Using multiple model in django form

 To use profile model with user form we need to initialize the form fields in the form. Then to get the values on edit we need to initialize __init__ function and passing the profile object from the view

 Ex: forms.py
 class SuperUserEditForm(forms.ModelForm):
    birthday = forms.DateTimeField(input_formats=['%Y-%m-%d %I:%M %p'], required=False)
    phone_number = forms.CharField(max_length=100, required=False, label="Home Phone")
    cell_number = forms.CharField(max_length=100, required=False)
    carrier = forms.ChoiceField(choices=CARRIERS, required=False)
   
    def __init__(self, profile=None, *args, **kwargs):
        super(SuperUserEditForm, self).__init__(*args, **kwargs)
        if(profile):
            self.fields['cell_number'].initial = profile.cell_number
            self.fields['carrier'].initial = profile.carrier
            self.fields['birthday'].initial = profile.birthday
            self.fields['phone_number'].initial = profile.phone_number

 Ex: views.py
     form = SuperUserEditForm(profile=profile, instance=user)

     on POST
     form = SuperUserEditForm(data=request.POST, instance=user)
