When to use get_user_model()

[tango ward]

Hi,

I am playing around with user registration. I came across a code where the
get_user_model() was assigned to a model in Meta class inside a form. I was
just wondering, what is the benefit of using the get_user_model() as Model
in a form instead of importing a class from models.py then use that class
as model of the form and when should I use it?

models.py
class RegUser(User):

    def __str__(self):
        return self.username

forms.py

class UserCreateForm(UserCreationForm):

    class Meta:
        fields = ('username', 'password1', 'password2')
        model = get_user_model()


Thanks,
Jarvis
