Automatically search through ForeignKey fields?

[kevinrenskers]

I have many models that have a ForeignKey field to the User model. When I use django-admin-site-search to search for "someuser@example.com" by default I only get that user as a result, not also all the objects that belong to this user.

I can extend the filter like so:

class MyAdminSite(AdminSiteSearchView, admin.AdminSite):
    site_header = "Sound Radix site admin"

    def filter_field(self, query, field):
        if isinstance(field, ForeignKey) and field.related_model is User:
            return Q(**{f"{field.name}__email__icontains": query})

        return super().filter_field(query, field)

And then I see many more results, as I'd expect. But it's kind of annoying to have to add these filters by hand for all possible related models (obviously I have ForeignKey fields to other models too). Can this be automated somehow?

Yeah - I think having this as an opt-in via the admin's search fields, as per #22, is the way to go. Adding it on top of the current implementation would make performance even more problematic.
