Upgrade considerations¶
EditHandler.bind_to_model
and EditHandler.bind_to_instance
deprecated¶
The internal EditHandler
methods bind_to_model
and bind_to_instance
have been deprecated, in favor of a new combined bind_to
method which accepts model
, instance
, request
and form
as optional keyword arguments. Any user code which calls EditHandler.bind_to_model(model)
should be updated to use EditHandler.bind_to(model=model)
instead; any user code which calls EditHandler.bind_to_instance(instance, request, form)
should be updated to use EditHandler.bind_to(instance=instance, request=request, form=form)
.
Changes to admin pagination helpers¶
Several changes have been made to pagination handling within the Wagtail admin; these are internal API changes, but may affect applications and third-party packages that add new paginated object listings, including chooser modals, to the admin. The paginate
function in wagtail.utils.pagination
has been deprecated in favor of the django.core.paginator.Paginator.get_page
method introduced in Django 2.0 - a call such as:
from wagtail.utils.pagination import paginate
paginator, page = paginate(request, object_list, per_page=25)
should be replaced with:
from django.core.paginator import Paginator
paginator = Paginator(object_list, per_page=25)
page = paginator.get_page(request.GET.get('p'))
Additionally, the is_ajax
flag on the template wagtailadmin/shared/pagination_nav.html
has been deprecated in favour of a new template wagtailadmin/shared/ajax_pagination_nav.html
:
{% include "wagtailadmin/shared/pagination_nav.html" with items=page_obj is_ajax=1 %}
should become:
{% include "wagtailadmin/shared/ajax_pagination_nav.html" with items=page_obj %}
New rich text formats¶
Wagtail now has built-in support for new rich text formats, disabled by default:
blockquote
, using theblockquote
Draft.js block type, saved as a<blockquote>
tag.superscript
, using theSUPERSCRIPT
Draft.js inline style, saved as a<sup>
tag.subscript
, using theSUBSCRIPT
Draft.js inline style, saved as a<sub>
tag.strikethrough
, using theSTRIKETHROUGH
Draft.js inline style, saved as a<s>
tag.code
, using theCODE
Draft.js inline style, saved as a<code>
tag.
Projects already using those exact Draft.js type and HTML tag combinations can safely replace their feature definitions with the new built-ins. Projects that use the same feature identifier can keep their existing feature definitions as overrides. Finally, if the Draft.js types / HTML tags are used but with a different combination, do not enable the new feature definitions to avoid conflicts in storage or editor behavior.
register_link_type
and register_embed_type
methods for rich text tag rewriting have changed¶
The FeatureRegistry.register_link_type
and FeatureRegistry.register_embed_type
methods, which define how links and embedded media in rich text are converted to HTML, now accept a handler class. Previously, they were passed an identifier string and a rewrite function. For details of updating your code to the new convention, see Rewrite handlers.
Chinese language locales changed to zh_Hans
and zh_Hant
¶
The translations for Chinese (Simplified) and Chinese (Traditional) are now available under the locale names zh_Hans
and zh_Hant
respectively, rather than zh_CN
and zh_TW
. Projects that currently use the old names for the LANGUAGE_CODE
setting may need to update the settings file to use the new names.
