Re: djano user registration form and login(full example)

Hello again,

In extended auth user model, is there any way to handle unique fields with django forms.

Lets say I have model like:

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    phone_num = models.BigIntegerField(null=True, unique=True)

    def __unicode__(self):
    return "%s" % self.user


so how can a user gets an error message if the phone number already exist?
Is there any django way to handle this??

Thanx,

Btw, I solved it by creating an instance of get_profile() and then saving user and profile separately.

here is the code snippet of forms.py

if commit:
        profile = user.get_profile()
        profile.serial_num = self.cleaned_data['serial_num']
        profile.save()
        user.save()
 return user, profile

This error is occur when you're saving the member, not the user. When creating the member, you are not assigning the user.

Exception Type:     IntegrityError
Exception Value:     column user_id is not unique

Thanx Shawn,

UserCreationForm really helped.

Now I have a different problem, I'm trying to add custom feilds to auth user using storing-additional-information-about-users.

But now I m getting this error.

Exception Type:	IntegrityError
Exception Value:	column user_id is not unique

This is my models.py file:

from django.db import models

from django.contrib.auth.models import User

from django.db.models.signals import post_save

class UserProfile(models.Model):

    user = models.OneToOneField(User)

    sr_no = models.CharField(max_length=10)

    def __unicode__(self):

        return self.sr_no

def create_user_profile(sender, instance, created, **kwargs):

    if created:

        UserProfile.objects.create(user=instance)

post_save.connect(create_user_profile, sender=User)

I have added unique field, but it does not make any difference. So far I haven't got

any convincing answer. 

Any Idea ??

Don't even worry about factories. They're for when you want a bunch of
forms for the same model on the page at once.

Use the UserCreationForm in django.contrib.auth.forms. It only accepts
a username and password, so you can either subclass it to add the
fields or make your own form and add it to your view so that they both
appear in the same HTML form. You can validate both and do what you
need to do.

You definitely shouldn't be writing validation logic for the password
and username and such -- that's what ModelForms are for.

If you have more specific questions just ask.
