Preserving filters in the admin interface to match django.

[ollz272]

Is your proposal related to a problem?

In the django admin interface, if you have a filter applied in the list view, when going to the detail view these filters will be preserved so that, upon returning to the list view, they're still in place. We've had some questions from partners about this feature in the wagtail interface, and maybe its time to explore whether this is possible?

Describe the solution you'd like

The cleanest solution would likely to be referencing the current django implementation:

• https://github.com/django/django/blob/f3cd252cfc46c0c7d66e765818dd3dadf60d4d0e/django/contrib/admin/options.py#L1161-L1179 is used to get any filters
• And then when generating urls, these preserved filters are then applied to them;

Describe alternatives you've considered

Internally, we have used a session to store the filters of a given admin model, and then reapply these when a model admin is resaved. Im not sure this is the best solution for wagtail, though.

Hi, can you elaborate a little bit more how did you did this? I am trying to keep the filters but I have no ideia where to start.
