This change modifies how the Wagtail home site summary panel displays
the number of pages on the site, and where that number links to.
Instead of showing the total number of pages on the site, the panel
should show the number of pages under the user's explorable root page
(inclusive). If the user has access to the full tree, the Wagtail root
is not counted in this total.
Previously, the site summary page link would go to the Wagtail root if
there were multiple sites in an installation, and to the site root page
for a single site. This change modifies this logic so that the link
always goes to the user's explorable root page (which may be their
explorable root page).
The unit tests for the site summary panel have been pulled out into a
new module at `wagtail.admin.tests.test_site_summary`, and augmented to
test how things work for users with different permissions.
This implements a new "find" view for all endpoints which can be used
for finding an individual object based on the URL parameters passed to
it.
If an object is found, the view will return a ``302`` redirect to detail
page of that object. If not, the view will return a ``404`` response.
For the pages endpoint, I've added a ``html_path`` parameter to this
view, this allows finding a page by its path on the site.
For example a GET request to ``/api/v2/pages/find/?html_path=/`` will
always generate a 302 response to the detail view of the homepage. This
uses Wagtail's internal routing mechanism so routable pages are
supported as well.
Fixes #4154
Searching the docs for the phrases "add django model to wagtail admin" and "add model to wagtail admin" (without the quotes) did not even yield this crucial page as one of the results. The proposed wording puts the main idea of being able to show/edit ANY model via the Wagtail admin at the top of the document and includes wording to, hopefully, have this page appear at the top for anyone searching for how to implement this functionality.
* Add a new hook 'register_account_menu_item'
This new hook makes it easier for third party apps to add new buttons on
the 'my account' page in the Wagtail admin. Existing buttons are
converted to the new hooks to make the code consistent.
* Add documentation for the new register_account_menu_item hook
