Equal on foreign key raise Related Field got invalid lookup: iexact #66
Description
If I create an admin model :
class MyModelAdmin(AdminAdvancedFiltersMixin, admin.ModelAdmin):
advanced_filter_fields = ['related_obj'] # related_obj is a foreign key
And try to create a custom filter with related_obj + EQUALS + 1 I get the following traceback when executing the filter:
Traceback:
