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:
{{{
Traceback (most recent call last):

) 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.
