Can't create super user with custom user model in Django 1.5

There are three ways for you in this case

1) Make relation to company Not required company = models.ForeignKey('Company', null=True)

2) Add default company and provide it as default value to foreign key field company = models.ForeignKey('Company', default=1) #where 1 is id of created company

3) Leave model code as is. Add fake company for superuser named for example 'Superusercompany' set it in create_superuser method.

UPD: according to your comment way #3 would be the best solution not to break your business logic.

Thanks to your feedback here is the solution I made: A custom MyUserManager where I created a default company

    def create_superuser(self, email, password, company=None):
        """
        Creates and saves a superuser with the given email and password.
        """

        if not company:
            company = Company(
                name="...",
                address="...",
                code="...",
                city="..."
            )
            company.save()

        user = self.create_user(
            email,
            password=password,
            company=company
        )
        user.is_admin = True
        user.save(using=self._db)
        return user
