Django - Create user profile on user creation


I'm following Django documentation here in order to achieve a simple objective: Create a user profile as soon as a new user is created.

I have an 'accounts' app and my accounts.models looks like this:

# -*- coding: utf-8 -*-
from django.db import models
from django.db.models.signals import post_save
from django.contrib.auth.models import User
from main.models import Store

class UserProfile(models.Model):

    GENRE_CHOICES = (
        ('m', 'Masculino'),
        ('f', 'Feminino'),
    )
    MARITAL_STATUS_CHOICES = (
        ('s', 'Solteiro'),
        ('c', 'Casado'),
        ('d', 'Divorciado'),
        ('v', 'Viúvo'),
    )

    user = models.ForeignKey(User, unique=True)
    birth_date = models.DateField()
    genre = models.CharField(max_length=1, choices=GENRE_CHOICES)
    address = models.CharField(max_length=150)
    postal_code_4 = models.PositiveIntegerField()
    postal_code_3 = models.PositiveIntegerField()
    locatity = models.CharField(max_length=30)
    marital_status = models.CharField(max_length=1, choices=MARITAL_STATUS_CHOICES)
    child_amount = models.PositiveSmallIntegerField()
    is_merchant = models.BooleanField(default=False)
    store = models.ForeignKey(Store, null=True)

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

post_save.connect(create_user_profile, sender=User)

Everything looks fine to me but when trying to add a new user (using django admin), instead of having a newly created user and user profile, I get the following error: InternalError at /admin/auth/user/add/ current transaction is aborted, commands ignored until end of transaction block

Here is the traceback error part:

/djangoProjects/lwboanova/lwboanova/apps/accounts/models.py in create_user_profile

34: UserProfile.objects.create(user=instance)

It seems like an integrity error but I'm not getting the reason for it.

Would be great if any of ya could give me some help on this.


Solution

  • Just figured it out.

    I forgot to add null=True to the rest of UserProfile model fields.

    So the accounts.models.UserProfile fields now looks like:

    user = models.ForeignKey(User, unique=True)
    birth_date = models.DateField(null=True)
    genre = models.CharField(max_length=1, choices=GENRE_CHOICES, null=True)
    address = models.CharField(max_length=150, null=True)
    postal_code_4 = models.PositiveIntegerField(null=True)
    postal_code_3 = models.PositiveIntegerField(null=True)
    locatity = models.CharField(max_length=30, null=True)
    marital_status = models.CharField(max_length=1, choices=MARITAL_STATUS_CHOICES, null=True)
    child_amount = models.PositiveSmallIntegerField(null=True)
    is_merchant = models.BooleanField(default=False)
    store = models.ForeignKey(Store, null=True)
    

    ...and everything is working as intended!

    Cheers for trying to help Ashray ^^
