Change IntegerField to smaller integer provider.

faker.rand_int(-4294967295, 4294967295) return values outside range supported by all django databases (-2147483648 to 2147483647): https://docs.djangoproject.com/en/1.8/ref/models/fields/#integerfield

Alternatively, you could:

  if isinstance(field, IntegerField): return lambda x: random.randint(-2147483648 , 2147483647)
