29019	createsuperuser crashes if a ManyToManyField is in REQUIRED_FIELDS	James Kirsop	Hasan Ramezani	"I've defined a custom user model with a ManyToMany field.

When running `manage.py createsuperuser` I receive the following error after entering the user's email address:

{{{

    ) if field.remote_field else '',
AttributeError: 'ManyToManyRel' object has no attribute 'field_name'
}}}

**Models**
My custom user model is defined as such (relevant pieces only included):
{{{
class OrgUser(AbstractBaseUser, PermissionsMixin):
	email = models.EmailField(
		verbose_name='email address',
		max_length=255,
		unique=True,
	)
	orgs = models.ManyToManyField(Organisation)
	USERNAME_FIELD = 'email'
	REQUIRED_FIELDS = ['orgs']
        objects = OrgUserManager()
}}}

and Organisations
{{{
class Organisation(models.Model):
	name = models.CharField(max_length=60)

	def __str__(self):
		return self.name
}}}

It seems that if I remove the need for the Orgs to be a `REQUIRED_FIELD` the issue goes away. However, it's central to my project and needs to be defined on every user.

Happy to update the ticket with any other code snippets if required."	Bug	closed	contrib.auth	dev	Normal	fixed	user custom		Accepted	1	0	0	0	0	0
