Question

It’s taking me way to long to make this simple form. Almost there but when I submit I get the NoneType error

views.py:

from djangoproject1.authentication import forms
from django.contrib.auth.models import User
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response

def main(request):
    rf = forms.RegisterForm()
    pf = forms.ProfileForm()
    return render_to_response("authentication/index.html", {'form1': rf, 'form2':pf})

def register(request):
    if request.method == 'POST':
        rf = forms.RegisterForm(request.POST)
        pf = forms.ProfileForm(request.POST)
        if rf.is_valid() and pf.is_valid():
            newuser = User(username=rf.cleaned_data['username'],email=rf.cleaned_data['email']) # this is the offending line
            newuser.set_password(rf.cleaned_data['password'])
            newuser.save()
            profile = pf.save(commit=False)
            profile.user = newuser
            profile.save()
            return HttpResponseRedirect("/register-success/")
    else: 
        return main(request)

forms.py:

from django import forms
from djangoproject1.authentication.models import UserProfile    

class RegisterForm(forms.Form):
    username = forms.CharField(min_length=6,max_length=15)
    password = forms.CharField(min_length=6,max_length=15,widget = forms.PasswordInput())
    cpassword = forms.CharField(label='Confirm Password',widget = forms.PasswordInput())
    email = forms.EmailField(label='E-mail Address')

    def clean(self):
        if self.cleaned_data['cpassword']!=self.cleaned_data['password']:
            raise forms.ValidationError("Passwords don't match")

class ProfileForm(forms.ModelForm):
    phonenumber = forms.CharField(label='Phone Number')

    class Meta:
        model = UserProfile
        exclude = ('user')

Answer 1

Your clean method in the forms.py should return the self.cleaned_data, if it doesn’t raise an error.

Currently, it is returning None (as you are not returning anything explicitly)
