Question

Can we define multiple models in the “Meta class” part of a Form ?

Here is my example:

from django import forms

from django.contrib.auth.models import User , Group

from django.forms import ModelForm

from django.utils.translation import ugettext as _

from profiles.models import Student , Tutor 


class RegistrationForm(ModelForm):
    email           = forms.EmailField(label=_('Email Address:'))
    password        = form.CharField(label=_('Passsword:') , widget = forms.PasswordInput(render_value = False))
    password1       = form.CharField(label=_('Verify Passsword:') , widget = forms.PasswordInput(render_value = False))

    class Meta:
        model = [Student , Tutor] ## IS THIS TRUE ???

No. But you don’t need to. Instead of instantiating and validating a single form, do it for each type of form you need to support.

# Define your model forms like you normally would
class StudentForm(ModelForm):
    ...

class TutorForm(ModelForm):
    ...

class RegistrationForm(Form):
    email = ...
    ...

# Your (simplified) view:
...
context = {
    'student_form': StudentForm(),
    'tutor_form': TutorForm(),
    'registration_form': RegistrationForm()
}
return render(request, 'app/registration.html', context)

# Your template
...
<form action="." method="post">
    {{ student_form }}
    {{ tutor_form }}
    {{ registration_form }}
    <input type="submit" value="Register">
</form>

If this means field names are duplicated across forms, use form prefixes to sort that out.
