If I have a couple of models like these (just an example)....
class Parent(models.Model):
name = models.CharField(max_length=100)
class Gender(models.Model):
name = models.CharField(max_length=100)
class Child(models.Model):
entity = models.ForeignKey(Entity, related_name=’children’)
gender = models.ForeignKey(Gender)
name = models.CharField(max_length=100)
How can i get a list of parents that _doesn't_ have a child of a
certain gender?
>>> gender = Gender.objects.get(name='female')
>>> Parent.objects.filter(#whatever that gets parents that doesn't have a child
>>> with gender=gender#)
I'm completely lost here so please help me out.
If it was about getting parents with no children then
"children__isnull=True" should do it but now I don't know.
The answer is probably obvious but I'm suffering from a mental block
right here.
