Adding reports¶

Defining your report¶

The most important attributes and methods to customize 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.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 view, defaults to "wagtailadmin/reports/base_report.html". Note that this template only provides the skeleton of the view, not the listing table itself. The listing table should be implemented in a separate template specified by results_template_name (see below), to then be rendered via {% include %}. Unless you want to customize the overall view, you will rarely need to change this template. To customize the listing, change the results_template_name instead.

results_template_name¶

(string)

The template used to render the listing table. For ReportView, this defaults to "wagtailadmin/reports/base_report_results.html", which provides support for using the wagtail.admin.ui.tables framework. For PageReportView, this defaults to "wagtailadmin/reports/base_page_report_results.html", which provides a default table layout 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.

page_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 For our example, we’ll set it to "Pages with unpublished changes".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'.

index_url_name¶

(string)

The name of the URL pattern registered for the report view.

index_results_url_name¶

(string)

The name of the URL pattern registered for the results view (the report view with .as_view(results_only=True)).

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.

Customizing 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_results.html, and wagtailadmin/reports/listing/_list_page_report.html.

{# <project>/templates/reports/unpublished_changes_report_results.html #}

{% extends 'wagtailadmin/reports/base_page_report_results.html' %}

{% block results %}
    {% include 'reports/include/_list_unpublished_changes.html' %}
{% endblock %}

{% block no_results_message %}
    <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.results_template_name to this new template: 'reports/unpublished_changes_report_results.html'.

Adding a menu item and admin URL¶

To add a menu item for your new report to the Reports submenu, you will need to use the register_reports_menu_item hook (see: Register Reports Menu Item). To add an admin url for the report, you will need to use the register_admin_urls hook (see: Register Admin URLs). This can be done as follows:

# <project>/wagtail_hooks.py

from django.urls import path, reverse

from wagtail.admin.menu import AdminOnlyMenuItem
from wagtail import hooks

from .views import UnpublishedChangesReportView

@hooks.register('register_reports_menu_item')
def register_unpublished_changes_report_menu_item():
    return AdminOnlyMenuItem("Pages with unpublished changes", reverse('unpublished_changes_report'), icon_name=UnpublishedChangesReportView.header_icon, order=700)

@hooks.register('register_admin_urls')
def register_unpublished_changes_report_url():
    return [
        path('reports/unpublished-changes/', UnpublishedChangesReportView.as_view(), name='unpublished_changes_report'),
        # Add a results-only view to add support for AJAX-based filtering
        path('reports/unpublished-changes/results/', UnpublishedChangesReportView.as_view(results_only=True), name='unpublished_changes_report_results'),
    ]

Here, we use the AdminOnlyMenuItem class to ensure our report icon is only shown to superusers. To make the report visible to all users, you could replace this with MenuItem.

Setting up permission restriction¶

Even with the menu item hidden, it would still be possible for any user to visit the report’s URL directly, and so it is necessary to set up a permission restriction on the report view itself. This can be done by adding a dispatch method to the existing UnpublishedChangesReportView view:

    # add the below dispatch method to the existing UnpublishedChangesReportView view
    def dispatch(self, request, *args, **kwargs):
        if not self.request.user.is_superuser:
            return permission_denied(request)
        return super().dispatch(request, *args, **kwargs)

The full code¶

# <project>/views.py

from wagtail.admin.auth import permission_denied
from wagtail.admin.views.reports import PageReportView
from wagtail.models import Page

class UnpublishedChangesReportView(PageReportView):
    index_url_name = "unpublished_changes_report"
    index_results_url_name = "unpublished_changes_report_results"
    header_icon = 'doc-empty-inverse'
    results_template_name = 'reports/unpublished_changes_report_results.html'
    page_title = "Pages with unpublished changes"

    list_export = PageReportView.list_export + ['last_published_at']
    export_headings = dict(last_published_at='Last Published', **PageReportView.export_headings)

    def get_queryset(self):
        return Page.objects.filter(has_unpublished_changes=True)

    def dispatch(self, request, *args, **kwargs):
        if not self.request.user.is_superuser:
            return permission_denied(request)
        return super().dispatch(request, *args, **kwargs)

def register_unpublished_changes_report_url():
    return [
        path('reports/unpublished-changes/', UnpublishedChangesReportView.as_view(), name='unpublished_changes_report'),
        path('reports/unpublished-changes/results/', UnpublishedChangesReportView.as_view(results_only=True), name='unpublished_changes_report_results'),
    ]
