Django – 创建用户配置文件

,以实现一个简单的目标：创建一个新的用户创建一个用户配置文件.

我有一个’帐户’应用程序和我的帐户.模型看起来像这样：

# -*- 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)

一切都看起来不错,但是当尝试添加新用户(使用django管理员),而不是拥有新创建的用户和用户配置文件时,我会收到以下错误：

/ admin / auth / user / add /

当前事务被中止,命令被忽略,直到事务块结束

这是追溯错误部分：

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

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

这似乎是一个完整性错误,但我没有得到它的理由.

如果有任何一个可以给我一些帮助,这将是伟大的.

只是想出来

我忘了在其余的UserProfile模型字段中添加’null = True’字段选项=)

所以accounts.models UserProfile字段现在看起来像：

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)

…一切都按照预期工作！
