Model Reference¶
wagtail.models is split into submodules for maintainability. All definitions intended as public should be imported here (with ‘noqa’ comments as required) and outside code should continue to import them from wagtail.models (e.g. from wagtail.models import Site, not from wagtail.models.sites import Site.)
Submodules should take care to keep the direction of dependencies consistent; where possible they should implement low-level generic functionality which is then imported by higher-level models such as Page.
This document contains reference information for the model classes inside the wagtailcore
module.
Page
¶
Database fields¶
- class wagtail.models.Page¶
- title¶
(text)
Human-readable title of the page.
- draft_title¶
(text)
Human-readable title of the page, incorporating any changes that have been made in a draft edit (in contrast to the
title
field, which for published pages will be the title as it exists in the current published version).
- slug¶
(text)
This is used for constructing the page’s URL.
For example:
http://domain.com/blog/[my-slug]/
- content_type¶
(foreign key to
django.contrib.contenttypes.models.ContentType
)A foreign key to the
ContentType
object that represents the specific model of this page.
- live¶
(boolean)
A boolean that is set to
True
if the page is published.Note: this field defaults to
True
meaning that any pages that are created programmatically will be published by default.
- has_unpublished_changes¶
(boolean)
A boolean that is set to
True
when the page is either in draft or published with draft changes.
- owner¶
(foreign key to user model)
A foreign key to the user that created the page.
- first_published_at¶
(date/time)
The date/time when the page was first published.
- last_published_at¶
(date/time)
The date/time when the page was last published.
- seo_title¶
(text)
Alternate SEO-crafted title, for use in the page’s
<title>
HTML tag.
- search_description¶
(text)
SEO-crafted description of the content, used for search indexing. This is also suitable for the page’s
<meta name="description">
HTML tag.
(boolean)
Toggles whether the page should be included in site-wide menus, and is shown in the
promote_panels
within the Page editor.Wagtail does not include any menu implementation by default, which means that this field will not do anything in the front facing content unless built that way in a specific Wagtail installation.
However, this is used by the
in_menu()
QuerySet filter to make it easier to query for pages that use this field.Defaults to
False
and can be overridden on the model withshow_in_menus_default = True
.Note
To set the global default for all pages, set
Page.show_in_menus_default = True
once where you first import thePage
model.
- locked¶
(boolean)
When set to
True
, the Wagtail editor will not allow any users to edit the content of the page.If
locked_by
is also set, only that user can edit the page.
- locked_by¶
(foreign key to user model)
The user who has currently locked the page. Only this user can edit the page.
If this is
None
whenlocked
isTrue
, nobody can edit the page.
- locked_at¶
(date/time)
The date/time when the page was locked.
- alias_of¶
(foreign key to another page)
If set, this page is an alias of the page referenced in this field.
- locale¶
(foreign key to Locale)
This foreign key links to the
Locale
object that represents the page language.
- translation_key¶
(uuid)
A UUID that is shared between translations of a page. These are randomly generated when a new page is created and copied when a translation of a page is made.
A translation_key value can only be used on one page in each locale.
Methods and properties¶
In addition to the model fields provided, Page
has many properties and methods that you may wish to reference, use, or override in creating your own models.
Note
See also django-treebeard’s `node API https://django-treebeard.readthedocs.io/en/latest/api.html. Page
is a subclass of materialized path tree nodes.
- class wagtail.models.Page
- get_specific(deferred=False, copy_attrs=None, copy_attrs_exclude=None)¶
Return this page in its most specific subclassed form.
By default, a database query is made to fetch all field values for the specific object. If you only require access to custom methods or other non-field attributes on the specific object, you can use
deferred=True
to avoid this query. However, any attempts to access specific field values from the returned object will trigger additional database queries.By default, references to all non-field attribute values are copied from current object to the returned one. This includes:
Values set by a queryset, for example: annotations, or values set as a result of using
select_related()
orprefetch_related()
.Any
cached_property
values that have been evaluated.Attributes set elsewhere in Python code.
For fine-grained control over which non-field values are copied to the returned object, you can use
copy_attrs
to specify a complete list of attribute names to include. Alternatively, you can usecopy_attrs_exclude
to specify a list of attribute names to exclude.If called on a page object that is already an instance of the most specific class (e.g. an
EventPage
), the object will be returned as is, and no database queries or other operations will be triggered.If the page was originally created using a page type that has since been removed from the codebase, a generic
Page
object will be returned (without any custom field values or other functionality present on the original class). Usually, deleting these pages is the best course of action, but there is currently no safe way for Wagtail to do that at migration time.
- specific¶
Returns this page in its most specific subclassed form with all field values fetched from the database. The result is cached in memory.
- specific_deferred¶
Returns this page in its most specific subclassed form without any additional field values being fetched from the database. The result is cached in memory.
- specific_class¶
Return the class that this page would be if instantiated in its most specific form.
If the model class can no longer be found in the codebase, and the relevant
ContentType
has been removed by a database migration, the return value will beNone
.If the model class can no longer be found in the codebase, but the relevant
ContentType
is still present in the database (usually a result of switching between git branches without running or reverting database migrations beforehand), the return value will beNone
.
- cached_content_type¶
Return this page’s
content_type
value from theContentType
model’s cached manager, which will avoid a database query if the object is already in memory.
- page_type_display_name¶
A human-readable version of this page’s type
- get_url(request=None, current_site=None)¶
Return the ‘most appropriate’ URL for referring to this page from the pages we serve, within the Wagtail backend and actual website templates; this is the local URL (starting with ‘/’) if we’re only running a single site (i.e. we know that whatever the current page is being served from, this link will be on the same domain), and the full URL (with domain) if not. Return None if the page is not routable.
Accepts an optional but recommended
request
keyword argument that, if provided, will be used to cache site-level URL information (thereby avoiding repeated database / cache lookups) and, via theSite.find_for_request()
function, determine whether a relative or full URL is most appropriate.
- get_full_url(request=None)¶
Return the full URL (including protocol / domain) to this page, or None if it is not routable
- full_url¶
Return the full URL (including protocol / domain) to this page, or None if it is not routable
- relative_url(current_site, request=None)¶
Return the ‘most appropriate’ URL for this page taking into account the site we’re currently on; a local URL if the site matches, or a fully qualified one otherwise. Return None if the page is not routable.
Accepts an optional but recommended
request
keyword argument that, if provided, will be used to cache site-level URL information (thereby avoiding repeated database / cache lookups).
- get_site()¶
Return the Site object that this page belongs to.
- get_url_parts(request=None)¶
Determine the URL for this page and return it as a tuple of
(site_id, site_root_url, page_url_relative_to_site_root)
. Return None if the page is not routable.This is used internally by the
full_url
,url
,relative_url
andget_site
properties and methods; pages with custom URL routing should override this method in order to have those operations return the custom URLs.Accepts an optional keyword argument
request
, which may be used to avoid repeated database / cache lookups. Typically, a page model that overridesget_url_parts
should not need to deal withrequest
directly, and should just pass it to the original method when callingsuper
.
- route(request, path_components)¶
- serve(request, *args, **kwargs)¶
- context_object_name = None¶
Custom name for page instance in page’s
Context
.
- get_context(request, *args, **kwargs)¶
- get_template(request, *args, **kwargs)¶
- get_admin_display_title()¶
Return the title for this page as it should appear in the admin backend; override this if you wish to display extra contextual information about the page, such as language. By default, returns
draft_title
.
- preview_modes¶
A list of
(internal_name, display_name)
tuples for the modes in which this object can be displayed for preview/moderation purposes. Ordinarily an object will only have one display mode, but subclasses can override this - for example, a page containing a form might have a default view of the form, and a post-submission ‘thank you’ page. Set to[]
to completely disable previewing for this model.
- serve_preview(request, mode_name)¶
Returns an HTTP response for use in object previews.
This method can be overridden to implement custom rendering and/or routing logic.
Any templates rendered during this process should use the
request
object passed here - this ensures thatrequest.user
and other properties are set appropriately for the wagtail user bar to be displayed/hidden. This request will always be a GET.
- get_parent(update=False)¶
- Returns
the parent node of the current node object. Caches the result in the object itself to help in loops.
- get_ancestors(inclusive=False)¶
Returns a queryset of the current page’s ancestors, starting at the root page and descending to the parent, or to the current page itself if
inclusive
is true.
- get_descendants(inclusive=False)¶
Returns a queryset of all pages underneath the current page, any number of levels deep. If
inclusive
is true, the current page itself is included in the queryset.
- get_siblings(inclusive=True)¶
Returns a queryset of all other pages with the same parent as the current page. If
inclusive
is true, the current page itself is included in the queryset.
- get_translations(inclusive=False)¶
Returns a queryset containing the translations of this instance.
- get_translation(locale)¶
Finds the translation in the specified locale.
If there is no translation in that locale, this raises a
model.DoesNotExist
exception.
- get_translation_or_none(locale)¶
Finds the translation in the specified locale.
If there is no translation in that locale, this returns None.
- has_translation(locale)¶
Returns True if a translation exists in the specified locale.
- copy_for_translation(locale, copy_parents=False, alias=False, exclude_fields=None)¶
Creates a copy of this page in the specified locale.
- localized¶
Finds the translation in the current active language.
If there is no translation in the active language, self is returned.
Note: This will not return the translation if it is in draft. If you want to include drafts, use the
.localized_draft
attribute instead.
- localized_draft¶
Finds the translation in the current active language.
If there is no translation in the active language, self is returned.
Note: This will return translations that are in draft. If you want to exclude these, use the
.localized
attribute.
- search_fields¶
A list of fields to be indexed by the search engine. See Search docs Indexing extra fields
- subpage_types¶
A list of page models which can be created as children of this page type. For example, a
BlogIndex
page might allow aBlogPage
as a child, but not aJobPage
:class BlogIndex(Page): subpage_types = ['mysite.BlogPage', 'mysite.BlogArchivePage']
The creation of child pages can be blocked altogether for a given page by setting its subpage_types attribute to an empty array:
class BlogPage(Page): subpage_types = []
- parent_page_types¶
A list of page models which are allowed as parent page types. For example, a
BlogPage
may only allow itself to be created below theBlogIndex
page:class BlogPage(Page): parent_page_types = ['mysite.BlogIndexPage']
Pages can block themselves from being created at all by setting parent_page_types to an empty array (this is useful for creating unique pages that should only be created once):
class HiddenPage(Page): parent_page_types = []
To allow for a page to be only created under the root page (for example for
HomePage
models) set theparent_page_type
to['wagtailcore.Page']
.class HomePage(Page): parent_page_types = ['wagtailcore.Page']
- classmethod can_exist_under(parent)¶
Checks if this page type can exist as a subpage under a parent page instance.
See also:
Page.can_create_at()
andPage.can_move_to()
- classmethod can_create_at(parent)¶
Checks if this page type can be created as a subpage under a parent page instance.
- can_move_to(parent)¶
Checks if this page instance can be moved to be a subpage of a parent page instance.
- get_route_paths()¶
New in version 2.16.
Returns a list of paths that this page can be viewed at.
These values are combined with the dynamic portion of the page URL to automatically create redirects when the page’s URL changes.
Note
If using
RoutablePageMixin
, you may want to override this method to include the paths of popualar routes.Note
Redirect paths are ‘normalized’ to apply consistent ordering to GET parameters, so you don’t need to include every variation. Fragment identifiers are discarded too, so should be avoided.
- password_required_template¶
Defines which template file should be used to render the login form for Protected pages using this model. This overrides the default, defined using
PASSWORD_REQUIRED_TEMPLATE
in your settings. See Private pages
- is_creatable¶
Controls if this page can be created through the Wagtail administration. Defaults to
True
, and is not inherited by subclasses. This is useful when using multi-table inheritance, to stop the base model from being created as an actual page.
- max_count¶
Controls the maximum number of pages of this type that can be created through the Wagtail administration interface. This is useful when needing “allow at most 3 of these pages to exist”, or for singleton pages.
- max_count_per_parent¶
Controls the maximum number of pages of this type that can be created under any one parent page.
- exclude_fields_in_copy¶
An array of field names that will not be included when a Page is copied. Useful when you have relations that do not use ClusterableModel or should not be copied.
class BlogPage(Page): exclude_fields_in_copy = ['special_relation', 'custom_uuid']
The following fields will always be excluded in a copy - [‘id’, ‘path’, ‘depth’, ‘numchild’, ‘url_path’, ‘path’].
- base_form_class¶
The form class used as a base for editing Pages of this type in the Wagtail page editor. This attribute can be set on a model to customise the Page editor form. Forms must be a subclass of
WagtailAdminPageForm
. See Customising generated forms for more information.
- with_content_json(content)¶
Returns a new version of the page with field values updated to reflect changes in the provided
content
(which usually comes from a previously-saved page revision).Certain field values are preserved in order to prevent errors if the returned page is saved, such as
id
,content_type
and some tree-related values. The following field values are also preserved, as they are considered to be meaningful to the page as a whole, rather than to a specific revision:draft_title
live
has_unpublished_changes
owner
locked
locked_by
locked_at
latest_revision
latest_revision_created_at
first_published_at
alias_of
wagtail_admin_comments
(COMMENTS_RELATION_NAME)
- save(clean=True, user=None, log_action=False, **kwargs)¶
Overrides default method behaviour to make additional updates unique to pages, such as updating the
url_path
value of descendant page to reflect changes to this page’s slug.New pages should generally be saved via the
add_child()
oradd_sibling()
method of an existing page, which will correctly set thepath
anddepth
fields on the new page before saving it.By default, pages are validated using
full_clean()
before attempting to save changes to the database, which helps to preserve validity when restoring pages from historic revisions (which might not necessarily reflect the current model state). This validation step can be bypassed by calling the method withclean=False
.
- create_alias(*, recursive=False, parent=None, update_slug=None, update_locale=None, user=None, log_action='wagtail.create_alias', reset_translation_key=True, _mpnode_attrs=None)¶
- update_aliases(*, revision=None, user=None, _content=None, _updated_ids=None)¶
Publishes all aliases that follow this page with the latest content from this page.
This is called by Wagtail whenever a page with aliases is published.
- Parameters
revision (Revision, optional) – The revision of the original page that we are updating to (used for logging purposes).
user (User, optional) – The user who is publishing (used for logging purposes).
- has_workflow¶
Returns True if the page or an ancestor has an active workflow assigned, otherwise False
- get_workflow()¶
Returns the active workflow assigned to the page or its nearest ancestor
- workflow_in_progress¶
Returns True if a workflow is in progress on the current page, otherwise False
- current_workflow_state¶
Returns the in progress or needs changes workflow state on this page, if it exists
- current_workflow_task_state¶
Returns (specific class of) the current task state of the workflow on this page, if it exists
- current_workflow_task¶
Returns (specific class of) the current task in progress on this page, if it exists
Site
¶
The Site
model is useful for multi-site installations as it allows an administrator to configure which part of the tree to use for each hostname that the server responds on.
The find_for_request()
function returns the Site object that will handle the given HTTP request.
Database fields¶
- class wagtail.models.Site¶
- hostname¶
(text)
This is the hostname of the site, excluding the scheme, port and path.
For example:
www.mysite.com
Note
If you’re looking for how to get the root url of a site, use the
root_url
attribute.
- port¶
(number)
This is the port number that the site responds on.
- site_name¶
(text - optional)
A human-readable name for the site. This is not used by Wagtail itself, but is suitable for use on the site front-end, such as in
<title>
elements.For example:
Rod's World of Birds
- root_page¶
(foreign key to
Page
)This is a link to the root page of the site. This page will be what appears at the
/
URL on the site and would usually be a homepage.
- is_default_site¶
(boolean)
This is set to
True
if the site is the default. Only one site can be the default.The default site is used as a fallback in situations where a site with the required hostname/port couldn’t be found.
Methods and properties¶
- class wagtail.models.Site
- static find_for_request(request)¶
Find the site object responsible for responding to this HTTP request object. Try:
unique hostname first
then hostname and port
if there is no matching hostname at all, or no matching hostname:port combination, fall back to the unique default site, or raise an exception
NB this means that high-numbered ports on an extant hostname may still be routed to a different hostname which is set as the default
The site will be cached via request._wagtail_site
- root_url¶
This returns the URL of the site. It is calculated from the
hostname
and theport
fields.The scheme part of the URL is calculated based on value of the
port
field:80 =
http://
443 =
https://
Everything else will use the
http://
scheme and the port will be appended to the end of the hostname (for examplehttp://mysite.com:8000/
)
- static get_site_root_paths()¶
Return a list of SiteRootPath instances, most specific path first - used to translate url_paths into actual URLs with hostnames
Each root path is an instance of the SiteRootPath named tuple, and have the following attributes:
site_id - The ID of the Site record
root_path - The internal URL path of the site’s home page (for example ‘/home/’)
root_url - The scheme/domain name of the site (for example ‘https://www.example.com/’)
language_code - The language code of the site (for example ‘en’)
Locale
¶
The Locale
model defines the set of languages and/or locales that can be used on a site.
Each Locale
record corresponds to a “language code” defined in the :ref:wagtail_content_languages_setting
setting.
Wagtail will initially set up one Locale
to act as the default language for all existing content.
This first locale will automatically pick the value from WAGTAIL_CONTENT_LANGUAGES
that most closely matches the site primary language code defined in LANGUAGE_CODE
.
If the primary language code is changed later, Wagtail will not automatically create a new Locale
record or update an existing one.
Before internationalisation is enabled, all pages use this primary Locale
record.
This is to satisfy the database constraints, and makes it easier to switch internationalisation on at a later date.
Changing WAGTAIL_CONTENT_LANGUAGES
¶
Languages can be added or removed from WAGTAIL_CONTENT_LANGUAGES
over time.
Before removing an option from WAGTAIL_CONTENT_LANGUAGES
, it’s important that the Locale
record is updated to a use a different content language or is deleted.
Any Locale
instances that have invalid content languages are automatically filtered out from all
database queries making them unable to be edited or viewed.
Methods and properties¶
- class wagtail.models.Locale
- language_code¶
The language code that represents this locale
The language code can either be a language code on its own (such as
en
,fr
), or it can include a region code (such asen-gb
,fr-fr
).
- classmethod get_default()¶
Returns the default Locale based on the site’s LANGUAGE_CODE setting
- classmethod get_active()¶
Returns the Locale that corresponds to the currently activated language in Django.
- get_display_name()¶
TranslatableMixin
¶
TranslatableMixin
is an abstract model that can be added to any non-page Django model to make it translatable.
Pages already include this mixin, so there is no need to add it.
Database fields¶
The locale
and translation_key
fields have a unique key constraint to prevent the object being translated into a language more than once.
- class wagtail.models.TranslatableMixin¶
- locale¶
(Foreign Key to
Locale
)For pages, this defaults to the locale of the parent page.
- translation_key¶
(uuid)
A UUID that is randomly generated whenever a new model instance is created. This is shared with all translations of that instance so can be used for querying translations.
Methods and properties¶
- class wagtail.models.TranslatableMixin
- get_translations(inclusive=False)¶
Returns a queryset containing the translations of this instance.
- get_translation(locale)¶
Finds the translation in the specified locale.
If there is no translation in that locale, this raises a
model.DoesNotExist
exception.
- get_translation_or_none(locale)¶
Finds the translation in the specified locale.
If there is no translation in that locale, this returns None.
- has_translation(locale)¶
Returns True if a translation exists in the specified locale.
- copy_for_translation(locale)¶
Creates a copy of this instance with the specified locale.
Note that the copy is initially unsaved.
- classmethod get_translation_model()¶
Returns this model’s “Translation model”.
The “Translation model” is the model that has the
locale
andtranslation_key
fields. Typically this would be the current model, but it may be a super-class if multi-table inheritance is in use (as is the case forwagtailcore.Page
).
- localized¶
Finds the translation in the current active language.
If there is no translation in the active language, self is returned.
Note: This will not return the translation if it is in draft. If you want to include drafts, use the
.localized_draft
attribute instead.
PreviewableMixin
¶
PreviewableMixin
is a mixin class that can be added to any non-page Django model to allow previewing its instances.
Pages already include this mixin, so there is no need to add it.
New in version 4.0: The class is added to allow snippets to have live preview in the editor. See Making snippets previewable for more details.
Methods and properties¶
- class wagtail.models.PreviewableMixin¶
- preview_modes¶
A list of
(internal_name, display_name)
tuples for the modes in which this object can be displayed for preview/moderation purposes. Ordinarily an object will only have one display mode, but subclasses can override this - for example, a page containing a form might have a default view of the form, and a post-submission ‘thank you’ page. Set to[]
to completely disable previewing for this model.
- default_preview_mode¶
The default preview mode to use in live preview. This default is also used in areas that do not give the user the option of selecting a mode explicitly, e.g. in the moderator approval workflow. If
preview_modes
is empty, anIndexError
will be raised.
- is_previewable()¶
Returns
True
if at least one preview mode is specified inpreview_modes
.
- get_preview_context(request, mode_name)¶
Returns a context dictionary for use in templates for previewing this object.
- get_preview_template(request, mode_name)¶
Returns a template to be used when previewing this object.
Subclasses of
PreviewableMixin
must override this method to return the template name to be used in the preview. Alternatively, subclasses can also override theserve_preview
method to completely customise the preview rendering logic.
- serve_preview(request, mode_name)¶
Returns an HTTP response for use in object previews.
This method can be overridden to implement custom rendering and/or routing logic.
Any templates rendered during this process should use the
request
object passed here - this ensures thatrequest.user
and other properties are set appropriately for the wagtail user bar to be displayed/hidden. This request will always be a GET.
RevisionMixin
¶
RevisionMixin
is an abstract model that can be added to any non-page Django model to allow saving revisions of its instances.
Pages already include this mixin, so there is no need to add it.
New in version 4.0: The model is added to allow snippets to save revisions, revert to a previous revision, and compare changes between revisions. See Saving revisions of snippets for more details.
Database fields¶
Methods and properties¶
- class wagtail.models.RevisionMixin
- revisions¶
Returns revisions that belong to the object.
Subclasses should define a
GenericRelation
toRevision
and override this property to return thatGenericRelation
. This allows subclasses to customise therelated_query_name
of theGenericRelation
and add custom logic (e.g. to always use the specific instance inPage
).
- save_revision(user=None, submitted_for_moderation=False, approved_go_live_at=None, changed=True, log_action=False, previous_revision=None, clean=True)¶
Creates and saves a revision.
- Parameters
user – The user performing the action.
submitted_for_moderation – Indicates whether the object was submitted for moderation.
approved_go_live_at – The date and time the revision is approved to go live.
changed – Indicates whether there were any content changes.
log_action – Flag for logging the action. Pass
False
to skip logging. Can be passed an action string. Defaults to"wagtail.edit"
when noprevious_revision
param is passed, otherwise"wagtail.revert"
.previous_revision (Revision) – Indicates a revision reversal. Should be set to the previous revision instance.
clean – Set this to
False
to skip cleaning object content before saving this revision.
- Returns
The newly created revision.
- get_latest_revision_as_object()¶
Returns the latest revision of the object as an instance of the model. If no latest revision exists, returns the object itself.
- with_content_json(content)¶
Returns a new version of the object with field values updated to reflect changes in the provided
content
(which usually comes from a previously-saved revision).Certain field values are preserved in order to prevent errors if the returned object is saved, such as
id
. The following field values are also preserved, as they are considered to be meaningful to the object as a whole, rather than to a specific revision:latest_revision
If
TranslatableMixin
is applied, the following field values are also preserved:translation_key
locale
DraftStateMixin
¶
DraftStateMixin
is an abstract model that can be added to any non-page Django model to allow its instances to have unpublished changes.
This mixin requires RevisionMixin
to be applied. Pages already include this mixin, so there is no need to add it.
New in version 4.0: The model is added to allow snippets to have changes that are not immediately reflected to the instance. See Saving draft changes of snippets for more details.
Database fields¶
- class wagtail.models.DraftStateMixin¶
- live¶
(boolean)
A boolean that is set to
True
if the object is published.Note: this field defaults to
True
meaning that any objects that are created programmatically will be published by default.
- has_unpublished_changes¶
(boolean)
A boolean that is set to
True
when the object is either in draft or published with draft changes.
- first_published_at¶
(date/time)
The date/time when the object was first published.
- last_published_at¶
(date/time)
The date/time when the object was last published.
Methods and properties¶
- class wagtail.models.DraftStateMixin
- publish(revision, user=None, changed=True, log_action=True, previous_revision=None)¶
Publish a revision of the object by applying the changes in the revision to the live object.
- Parameters
revision (Revision) – Revision to publish.
user – The publishing user.
changed – Indicated whether content has changed.
log_action – Flag for the logging action, pass
False
to skip logging.previous_revision (Revision) – Indicates a revision reversal. Should be set to the previous revision instance.
- unpublish(set_expired=False, commit=True, user=None, log_action=True)¶

RevisionMixin.with_content_json()
, but with the following fields also preserved:live

Revision
¶
Every time a page is edited, a new Revision
is created and saved to the database. It can be used to find the full history of all changes that have been made to a page and it also provides a place for new changes to be kept before going live.
Revisions can be created from any instance of
RevisionMixin
by calling itssave_revision()
method.The content of the page is JSON-serialisable and stored in the
content
field.You can retrieve a
Revision
as an instance of the object’s model by calling theas_object()
method.
Changed in version 4.0: The model has been renamed from PageRevision
to Revision
and it now references the Page
model using a GenericForeignKey
.

- content_object¶
(generic foreign key)
The object this revision belongs to. For page revisions, the object is an instance of the specific class.
- content_type¶
(foreign key to
ContentType
)The content type of the object this revision belongs to. For page revisions, this means the content type of the specific page type.
- base_content_type¶
(foreign key to
ContentType
)The base content type of the object this revision belongs to. For page revisions, this means the content type of the
Page
model.

Managers¶
- class wagtail.models.Revision
- objects¶
This default manager is used to retrieve all of the
Revision
objects in the database. It also provides afor_instance()
method that lets you query for revisions of a specific object.Example:
Revision.objects.all() Revision.objects.for_instance(my_object)
- page_revisions¶
This manager extends the default manager and is used to retrieve all of the
Revision
objects that belong to pages.Example:
Revision.page_revisions.all()
New in version 4.0: This manager is added as a shorthand to retrieve page revisions.
- submitted_revisions¶
This manager extends the default manager and is used to retrieve all of the
Revision
objects that are awaiting moderator approval.Example:
Revision.submitted_revisions.all()
Methods and properties¶
- class wagtail.models.Revision
- as_object()¶
This method retrieves this revision as an instance of its object’s specific class. If the revision belongs to a page, it will be an instance of the
Page
’s specific subclass.Changed in version 4.0: This method has been renamed from
as_page_object()
toas_object()
.
- approve_moderation(user=None)¶
Calling this on a revision that’s in moderation will mark it as approved and publish it.
- reject_moderation(user=None)¶
Calling this on a revision that’s in moderation will mark it as rejected.
- is_latest_revision()¶
Returns
True
if this revision is the object’s latest revision.
