ForeignKey does not allow null values

Question

I am using the Django REST Framework 2.0.

Here is my model class:

class Mission(models.Model):
  assigned_to = models.ForeignKey(\'auth.User\',
                


        

Answer 1

In my case, required=False wasn't enough. I needed allow_null in the serializer, per Django ForeignKey field required despite blank=True and null=True.
