Description
If you customize queryset in ModelAdmin:
from app.models import License, Server from django.contrib import admin class LicenseAdmin(admin.ModelAdmin): def queryset(self, request): qs = super(LicenseAdmin, self).queryset(request) return qs.extra(select={'usage_count': "SELECT COUNT(id) FROM app_server WHERE license_id=license.id",}) list_display = ('name','description','product_key', 'usage_count') admin.site.register(License, LicenseAdmin)
and want to use extra field called usage_count, you get an error:
ImproperlyConfigured at /admin/app/license/ LicenseAdmin.list_display[3], 'usage_count' is not a callable or an attribute of 'LicenseAdmin' or found in the model 'License'.
Django Admin interface ignores extra field usage_count from QuerySet, or validates columns by another way, which doesn't include QuerySet changes.
