Django Queryset with filtering on reverse foreign key

Question

I have the following Django model:

class Make:
   name = models.CharField(max_length=200)

class MakeContent:
   make = models.ForeignKey(Make)
   published          


        

Answer 1

One more time, it is not clear what was the question, but if it was desired that all related MakeContent objects must have been published this can work:

Make.objects.exclude(MakeContent_set__published=False)

And if at least one of them (as it was in other answers):

Make.objects.filter(MakeContent_set__published=True)
