Re: [django-users] Error when registering a new user - Django 1.5
Variations on this problem report have been made a couple of times
UserCreateForm is a ModelForm. That means the line in your Meta clause for
model=get_user_model() is invoked at the time the module is loaded.
However, there's no guarantee at the time that module is loaded that the
user model has been defined yet -- so you can end up with errors.
There are two options here.
Option 1: We try to define a truly dynamic UserCreateForm that can adapt to
the changing requirements of a User model (and remember, this means
adapting to the REQUIRED_FIELDS as well). This code would be complex and
potentially fragile, since it needs to work with *any* User model, with
*any* collection of required fields.
Option 2: We provide a UserCreateForm that works with the default User
model, and with any AbstractUser descendent that isn't too significantly
modified, and we leave the UserCreateForm for any other User model an an
activity for the developer.
We've chosen Option 2, and documented as such:

Re: [django-users] Error when registering a new user - Django 1.5
I did it and aparently it worked:
*# forms.py*
*class UserCreateForm(UserCreationForm):*
*
*
*
def clean_username(self):
username = self.cleaned_data["username"]
try:
self._meta.model._default_manager.get(username=username)
except self._meta.model.DoesNotExist:
return username
raise
forms.ValidationError(self.error_messages['duplicate_username'])
*
*
*
*class Meta:*
*model = get_user_model()*
*fields = ('email', 'password1', 'password2', 'first_name',
'last_name', 'bio', 'username')*

Should not it be the UserCreationForm standard?

[django-users] Error when registering a new user - Django 1.5
Hi,
I am getting an error when registering a new user in a Django 1.5 app.
It is the postgres' log:
*BRT ERROR: relation "auth_user" does not exist at character 280*
*BRT COMMAND: SELECT "auth_user"."id", "auth_user"."password",
"auth_user"."last_login", "auth_user"."is_superuser",
"auth_user"."username", "auth_user"."first_name", "auth_user"."last_name",
"auth_user"."email", "auth_user"."is_staff", "auth_user"."is_active",
"auth_user"."date_joined" FROM "auth_user" WHERE "auth_user"."username" =
E'teste'*
*
*
My code is very simple:
*
*
*# models.py*
*class User(AbstractUser):*
*bio = models.CharField(max_length=255, blank=True, null=True)*
*objects = UserManager()*
*# forms.py*
*class UserCreateForm(UserCreationForm):*
*class Meta:*
*model = get_user_model()*
*fields = ('email', 'password1', 'password2', 'first_name',
'last_name', 'bio', 'username')*
*# views.py*
*class UserCreateView(CreateView):*
*form_class = UserCreateForm*
*model = get_user_model()*
*
*
I think that UserCreationForm yet search for auth_user table.
A possible solution would be this:
*# models.py*
*class User(AbstractUser):*
*bio = models.CharField(max_length=255, blank=True, null=True)*
*objects = UserManager()*
*class Meta:*
* db_table = u'auth_user'*
But i would like to use a correct Django 1.5 approach to register a new
user.
Can anyone spot the problem?
Regards,
Leonardo
