创建扩展用户配置文件 [英] Creating a extended user profile

问题描述

我在django中有一个扩展的UserProfile模型：

  class UserProfile（models.Model）：
 user = models.ForeignKey（User，unique = True）
＃该配置文件中的其他内容
  

一个signals.py：

  from registration.signals import user_registered 
 from models import UserProfile 
 from django。导入用户
 
 def createUserProfile（sender，instance，** kwargs）：
 profile = users.models.UserProfile（）
 profile.setUser（sender） 
 profile.save（）
 
 user_registered.connect（createUserProfile，sender = User）
  

我确保信号通过在我的 __ init __。py 中得到注册：

 导入信号
  

所以应该为每个人创建一个新的UserProfile注册用户，对吧？但是没有。当我尝试登录时，我总是得到UserProfile匹配查询不存在错误，这意味着数据库条目不存在。

我应该说我使用django-registration，它提供了user_registered信号。

这个重要的应用程序的结构是，我有一个名为users的应用程序，我有： models.py，signals.py，urls.py和views.py（以及其他一些在这里不重要的事情）。 UserProfile类在models.py中定义。

更新：我将signals.py更改为：

来自django.db.models.signals的

 导入post_save 
从模型import UserProfile 
 from django.contrib.auth.models import User 
 
 def create_profile（sender，** kw）：
 user = kw [instance] 
如果kw [created]：
 profile = UserProfile（）
 profile.user = user 
 profile.save（）
 
 post_save.connect（create_profile，sender =用户）
  

但现在我得到一个IntegrityError：

列user_id不唯一

编辑2：

我找到了。看起来不知何故，我注册了两次信号。以下介绍了解决方法： http://code.djangoproject.com/wiki/Signals#Helppost_saveseemstobeemittedtwiceforeachsave

我不得不添加一个dispatch_uid，现在我的signals.py看起来像这样，正在工作：

从django.db.models.signals导入post_save
从django.contrib.auth.models导入用户
从模型导入UserProfile
从django .db导入模型

def create_profile（sender，** kw）：
user = kw [instance]
如果kw [created]：
profile = UserProfile（user = user）
profile.save（）

post_save.connect（create_profile，sender = User，dispatch_uid =users-profilecreation-signal）

解决方案

您可以使用post_save在用户上实现：

$ b来自django.db.models.signals imp的
$ b

  ort post_save 
 from models import UserProfile 
 from django.contrib.auth.models import User 
 
 def create_profile（sender，** kwargs）：
 user = kwargs [ instance] 
如果kwargs [created]：
 profile = users.models.UserProfile（）
 profile.setUser（sender）
 profile.save（）
 
 post_save.connect（create_profile，sender = User）
  

编辑：

另一种可能的解决方案，经测试和工作（我在我的网站上使用它）：

 code>从django.db导入模型
从django.contrib.auth.models import用户
从django.db.models.signals import post_save 
 def create_profile（sender，** kwargs）
 user = kwargs [instance] 
如果kwargs [created]：
 up = UserProfile（user = user，stuff = 1，thing = 2）
 up.save（）
 post_save.connect（create_profile，sender = User）
  

I have an extended UserProfile model in django:

class UserProfile(models.Model):
  user = models.ForeignKey(User, unique=True)
  #other things in that profile

And a signals.py:

from registration.signals import user_registered
from models import UserProfile
from django.contrib.auth.models import User

def createUserProfile(sender, instance, **kwargs):
  profile = users.models.UserProfile()
  profile.setUser(sender)
  profile.save()

user_registered.connect(createUserProfile, sender=User)

I make sure the signal gets registered by having this in my __init__.py:

import signals

So that should create me a new UserProfile for every user that registers, right? But it doesn't. I always get "UserProfile matching query does not exist" errors when I try to log in, which means that the database entry isn't there.

I should say that I use django-registration, which provides the user_registered signal.

The structure of the important apps for this is, that I have one application called "users", there I have: models.py, signals.py, urls.py and views.py (and some other things which shouldn't matter here). The UserProfile class is defined in models.py.

Update: I changed the signals.py to:

from django.db.models.signals import post_save
from models import UserProfile
from django.contrib.auth.models import User

def create_profile(sender, **kw):
    user = kw["instance"]
    if kw["created"]:
        profile = UserProfile()
        profile.user = user
        profile.save()

post_save.connect(create_profile, sender=User)

But now I get a "IntegrityError":

"column user_id is not unique"

Edit 2:

I found it. Looks like somehow I registred the signal twice. The workaround for this is described here: http://code.djangoproject.com/wiki/Signals#Helppost_saveseemstobeemittedtwiceforeachsave

I had to add a dispatch_uid, now my signals.py looks like this and is working:

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from models import UserProfile
from django.db import models

def create_profile(sender, **kw):
    user = kw["instance"]
    if kw["created"]:
        profile = UserProfile(user=user)
        profile.save()

post_save.connect(create_profile, sender=User, dispatch_uid="users-profilecreation-signal")

解决方案

You can implement it using post_save on the user:

from django.db.models.signals import post_save
from models import UserProfile
from django.contrib.auth.models import User

def create_profile(sender, **kwargs):
    user = kwargs["instance"]
    if kwargs["created"]:
        profile = users.models.UserProfile()
        profile.setUser(sender)
        profile.save()

post_save.connect(create_profile, sender=User)

Edit:
Another possible solution, which is tested and works (I'm using it on my site):

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
def create_profile(sender, **kwargs):
    user = kwargs["instance"]
    if kwargs["created"]:
        up = UserProfile(user=user, stuff=1, thing=2)
        up.save()
post_save.connect(create_profile, sender=User)
