Can I have a Django model that has a foreign key reference to itself?

Question

Okay, how would I do this?

class Example(models.Model):
  parent_example = models.ForeignKey(Example)

I want to have a model have a foreign key reference to itself. When I try to create this I get a django validation error that Example is not yet defined.

Answer 1

Yes, just do this:

class Example(models.Model):
  parent_example = models.ForeignKey('self')

Answer 2

You should use

models.ForeignKey('self')

as mentioned here.
