Adding reports¶
Reports are views with listings of pages matching a specific query. They can also export these listings in spreadsheet format. They are found in the Reports submenu: by default, the Locked Pages report is provided, allowing an overview of locked pages on the site.
It is possible to create your own custom reports in the Wagtail admin. Two base classes are provided:
wagtail.admin.views.reports.ReportView
, which provides basic listing and spreadsheet export functionality, and
wagtail.admin.views.reports.PageReportView
, which additionally provides a default set of fields suitable for page listings.
For this example, we’ll add a report which shows any pages with unpublished changes.
# <project>/views.py
from wagtail.admin.views.reports import PageReportView
class UnpublishedChangesReportView(PageReportView):
pass
Defining your report¶
The most important attributes and methods to customise to define your report are:
-
get_queryset
(self)¶
This retrieves the queryset of pages for your report. For our example:
# <project>/views.py
from wagtail.admin.views.reports import PageReportView
from wagtail.core.models import Page
class UnpublishedChangesReportView(PageReportView):
def get_queryset(self):
return Page.objects.filter(has_unpublished_changes=True)
-
template_name
¶
(string)
The template used to render your report. For ReportView
, this defaults to "wagtailadmin/reports/base_report.html"
,
which provides an empty report page layout; for PageReportView
, this defaults to
"wagtailadmin/reports/base_page_report.html"
which provides a listing based on the explorer views,
displaying action buttons, as well as the title, time of the last update, status, and specific type of any pages.
In this example, we’ll change this to a new template in a later section.
-
title
¶
(string)
The name of your report, which will be displayed in the header. For our example, we’ll set it to
"Pages with unpublished changes"
.
-
header_icon
¶
(string)
The name of the icon, using the standard Wagtail icon names. For example, the locked pages view uses "locked"
,
and for our example report, we’ll set it to 'doc-empty-inverse'
.
Spreadsheet exports¶
-
list_export
¶
(list)
A list of the fields/attributes for each model which are exported as columns in the spreadsheet view. For ReportView
, this
is empty by default, and for PageReportView
, it corresponds to the listing fields: the title, time of the last update, status,
and specific type of any pages. For our example, we might want to know when the page was last published, so we’ll set
list_export
as follows:
list_export = PageReportView.list_export + ['last_published_at']
-
export_headings
¶
(dictionary)
A dictionary of any fields/attributes in list_export
for which you wish to manually specify a heading for the spreadsheet
column, and their headings. If unspecified, the heading will be taken from the field verbose_name
if applicable, and the
attribute string otherwise. For our example, last_published_at
will automatically get a heading of "Last Published At"
,
but a simple “Last Published” looks neater. We’ll add that by setting export_headings
:
export_headings = dict(last_published_at='Last Published', **PageReportView.export_headings)
-
custom_value_preprocess
¶
(dictionary)
A dictionary of (value_class_1, value_class_2, ...)
tuples mapping to {export_format: preprocessing_function}
dictionaries,
allowing custom preprocessing functions to be applied when exporting field values of specific classes (or their subclasses). If
unspecified (and ReportView.custom_field_preprocess
also does not specify a function), force_str
will be used. To prevent
preprocessing, set the preprocessing_function to None
.
-
custom_field_preprocess
¶
(dictionary)
A dictionary of field_name
strings mapping to {export_format: preprocessing_function}
dictionaries,
allowing custom preprocessing functions to be applied when exporting field values of specific classes (or their subclasses). This
will take priority over functions specified in ReportView.custom_value_preprocess
. If unspecified (and
ReportView.custom_value_preprocess
also does not specify a function), force_str
will be used. To prevent
preprocessing, set the preprocessing_function to None
.
Customising templates¶
For this example “pages with unpublished changes” report, we’ll add an extra column to the listing template, showing the last
publication date for each page. To do this, we’ll extend two templates: wagtailadmin/reports/base_page_report.html
, and
wagtailadmin/reports/listing/_list_page_report.html
.
{# <project>/templates/reports/unpublished_changes_report.html #}
{% extends 'wagtailadmin/reports/base_page_report.html' %}
{% block listing %}
{% include 'reports/include/_list_unpublished_changes.html' %}
{% endblock %}
{% block no_results %}
<p>No pages with unpublished changes.</p>
{% endblock %}
{# <project>/templates/reports/include/_list_unpublished_changes.html #}
{% extends 'wagtailadmin/reports/listing/_list_page_report.html' %}
{% block extra_columns %}
<th>Last Published</th>
{% endblock %}
{% block extra_page_data %}
<td valign="top">
{{ page.last_published_at }}
</td>
{% endblock %}
Finally, we’ll set UnpublishedChangesReportView.template_name
to this new template: 'reports/unpublished_changes_report.html'
.
