django reg extension-当前事务中止，命令被忽略，直到事务块结束

Question

I am trying to extend the django-registration register form according to:

Python/Django django-registration add an extra field

but I am getting:

current transaction is aborted, commands ignored until end of transaction block

In debugging I have added a breakpoint in the suggested regbackend.py which suggests the broken code is at:

from crewcal.models import UserProfile
from forms import *

def user_created(sender, user, request, **kwargs):
    form = CustomRegistrationForm(request.POST)
    data = UserProfile(user=user)
    import ipdb; ipdb.set_trace();
    data.locality = form.data["locality"]
    data.save()

from registration.signals import user_registered
user_registered.connect(user_created)

The problem (below), may have something to do with the way user profiles are created as defined in my models.py :

def create_user_profile(sender, instance, created, raw, **kwargs):
    if created and not raw:
        print vars(instance)
        UserProfile.objects.create(user=instance)

post_save.connect(create_user_profile, sender=User)

User.profile = property(lambda u: UserProfile.\
     objects.get_or_create(user=u)[0])

In the shell arising from the regbackend.py breakpoint listed above, I can produce:

    > /Users/project/app/regbackend.py(8)user_created()
      7     import ipdb; ipdb.set_trace();
----> 8     data.locality = form.data["locality"]
      9     data.save()

ipdb> data
<UserProfile: gub>
ipdb> vars(data)
{'user_id': 81, 'locality': None, '_user_cache': <User: gub>, '_state': <django.db.models.base.ModelState object at 0x103eb6990>, 'receive_email': True, 'id': None}
ipdb> form.data['locality']
u'BERLIN'
ipdb> data.locality = form.data['locality']
ipdb> vars(data)
{'user_id': 81, 'locality': u'BERLIN', '_user_cache': <User: gub>, '_state': <django.db.models.base.ModelState object at 0x103eb6990>, 'receive_email': True, 'id': None}
ipdb> data.save()

*** InternalError: current transaction is aborted, commands ignored until end of transaction block

ipdb>

and in the verbose trace (incl. sql) up to that point, I get:

I have tried feeding these commands in separately to dbshell, but I can't see the problem.

Any ideas?

When I face with something like adding special fields, or do any special action when creating an user I prefer to avoid overwrite User model and do like:

• You create a new model, for example Profile with a OneToOneField to user
• Add your desired fields to that profile model, such as (tlf, country, language,log...)
• Add any special action on create, such as save a log, store more info....
• Create admin.py to manage this model (profile) at the same time you manage users in django admin

Profile Model Example

class Profile(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=255, blank=True, null=True, verbose_name='phone')
    description = models.TextField(blank=True, verbose_name='descripction')
    ...
    ...
    def not_first_log(self):  
       # Just a tiny example of a function to mark user as first-logged
       self.first_log = False
       self.save()

    class Meta:
        ordering = ['user']
        verbose_name = 'user'
        verbose_name_plural = 'users'

---

admin.py example

# -*- coding: utf-8 -*-
from __future__ import unicode_literals    
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User


class ProfileInline(admin.StackedInline):
    model = Profile
    can_delete = False
    filter_horizontal = ['filter fields']  # example: ['tlf', 'country',...]
    verbose_name_plural = 'profiles'
    fk_name = 'user'

class UserAdmin(UserAdmin):
    inlines = (ProfileInline, )
    list_display = ('username', 'email', 'first_name', 'last_name', 'is_staff')
    list_filter = ('is_staff', 'is_superuser', 'is_active')

admin.site.unregister(User)  # Unregister user to add new inline ProfileInline
admin.site.register(User, UserAdmin)  # Register User with this inline profile

---

Create an user and attach a profile to him

# Create user
username = 'TestUser'
email = 'test@example.com'
passw = '1234'  
new_user = User.objects.create_user(username, email, passw)

# Create profile
phone = '654654654'
desc = 'Test user profile'
new_profile = Profile(user=new_user, phone = phone, description=desc)
new_profile.profile_role = new_u_prole
new_profile.user = new_user

# Save profile and user
new_profile.save()
new_profile.not_first_log()
new_user.save()

---

Now you'll have this Profile model attached to each user, and you could add the fields you wish to Profile Model, and for example if you make:

user = User.objects.get(id=1)

you can access to his profile doing:

user.profile

and to call any function

user.profile.function_name

You can also get the profile and do profile.user

---

I know you're trying to overwrite User model but I'm pretty sure this is way is less complex and easy to manage, add new fields,actions or whatever you need
