Django 2. How can I make the registration form inherit from 2 models, for example the built-in user model and my UserProfile model?

Question

Django

There are 2 form classes:

class ExtendedUserCreationForm(UserCreationForm):
  email = forms.EmailField(required = True)

  class Meta:
    model = User
    fields = ['username','email','password1','password2']

  def save(self,commit = True):
    user = super().save(commit = True)

    user.email = self.cleaned_data['email']
    
    if commit:
      user.save()
    return user 

class UserProfileForm(forms.ModelForm):
  class Meta:
    model = UserProfile
    fields = ('first_name','last_name','father_name')

And I need to make sure that instead of two classes there is one. And at the same time, all the fields of 2 models must be placed in one variable fields. I need this in order to sort the form fields in the template in the sequence I need. At the same time, I want to save the first_name and last_name fields both in the user model table and in the UserProfile table.

Create a Form (not a ModelForm, just a Form) with the set of fields you need. Implement the save method in it, where the specified fields are decomposed into the necessary models.
