Override default queryset in Django admin

Question

One of my models has a deleted flag, which is used to hide objects globally:

class NondeletedManager(models.Manager):
    \"\"\"Returns only objects which ha         


        

Answer 1

Konrad is correct, but this is more difficult than the example given in the documentation.

Deleted conversations can't be included in a queryset that already excludes them. So I don't see an option other than re-implementing admin.ModelAdmin.queryset entirely.

class ConversationAdmin (admin.ModelAdmin):

    def queryset (self, request):
        qs = Conversation.all_conversations
        ordering = self.get_ordering(request)
        if ordering:
            qs = qs.order_by(*ordering)
        return qs
