Instead of deleting pages when pressing delete, pages will get thrown into the "Trash Can".
First install the python package:
pip install wagtail-trash
Then add it to your INSTALLED_APPS
:
INSTALLED_APPS = [
# ...
"wagtail.contrib.modeladmin", # Wagtail Trash makes use of ModelAdmin, it needs to be installed.
"wagtail_trash",
]
Run migrations, et voila!
Wagtail Trash works by hooking into the Wagtail hook before_delete_page
and overriding the delete view.
Instead of deleting the page the page gets moved to the special "Trash" page. The deleted page and all descendants will get unpublished.
From the trash can in Wagtail admin it's then possible to permanently delete the page or to restore the page. Restoring a page will also republish the pages that were published when getting deleted.
If the parent of the deleted page is either in the trash can or permanently deleted it's still possible to restore the pages by supplying an alternate parent.
Since Wagtail Trash uses the hook before_delete_page
it might interfere with your applications before_delete_page
if you have defined one that returns a status code. Make sure wagtail trash is the last hook that runs otherwise or your custom before_delete_page
might not run since Wagtail Trash doesn't call it.
Also, Wagtail Trash "deletes" pages by unpublishing them, so if you use a queryset that doesn't filter out unpublished pages, pages in trash can might show up. There is a manager that will fix this for you included, example:
from wagtail_trash.managers import TrashManager
class SomePage(Page):
objects_excluding_trash = TrashManager()
# Now you can do this without getting any pages from the bin:
SomePage.objects_excluding_trash.all()
Permissions: If you remove a page under a restricted area, this page will be moved and therefore get new permissions. A user might go from not being allowed to see pages under e.g. "Secret Page", but when a page under this area is moved to trash can, the permissions from "Secret Page" are gone so now the user will see it in the trash can. This is a solvable issue and will be fixed in a later version.
There is an included managment-command called empty_trash
that takes a required argument --older_than_days
. To remove all items in the bin that's been there more than 30 days run this command:
./manage.py empty_trash --older_than_days=30
