嗨,我正在使用 sqlite3 数据库开发 django python 应用程序。我对在我的 models.py 中定义的 django 用户模型进行了扩展,如下所示:
#Account Model
class Account(models.Model):
user = models.OneToOneField(User)
avatar_url = models.CharField(max_length=200)
profile_url = models.CharField(max_length=200)
account_type = models.CharField(max_length=60, choices=choices.ACCOUNT_TYPE)
我也有一个方法来创建Account object
和post_save
定义这样的处理程序:
#Function to Create user Account/Profile
def create_user_account(sender, instance, created, **kwargs):
if created:
models.Account.objects.create(user=instance)
#Create User / User Registration
def UserRegistration(request):
if request.method == 'POST':
username = request.POST['fn'].capitalize() + ' ' + request.POST['ln'].capitalize()
# CREATE USER
newuser = User.objects.create_user(username=username,
email=request.POST['email'],
password=request.POST['pw'])
newuser.save()
return HttpResponse(username)
#Post Save handler to create user Account/Profile
post_save.connect(create_user_account, sender=User)
现在,每当我尝试注册新用户时,都会收到以下数据库错误:
DatabaseError at /register/
table engine_account has no column named user_id
Request Method: POST
Request URL: http://localhost:8000/register/
Django Version: 1.4
Exception Type: DatabaseError
Exception Value:
table engine_account has no column named user_id
Exception Location: /usr/local/lib/python2.7/dist-packages/Django-1.4-py2.7.egg/django/db/backends/sqlite3/base.py in execute, line 337
Python Executable: /usr/bin/python
Python Version: 2.7.3
我不知道那个"user_id"
领域是从哪里来的..有什么想法吗?
PS:
表 engine_account 基本上是Account
应用程序中名为的类Engine
