刚升级到Django 1.4并收到错误消息 [英] Just upgraded to Django 1.4 and getting error with messages

问题描述

我刚刚升级到Django 1.4，它破坏了包括消息传递在内的几项功能。

I just upgraded to Django 1.4 and it has broken a couple things including messaging.

这是我尝试更改头像时遇到的错误：

Here's the error I get when trying to change a avatar:

'User' object has no attribute 'message_set'
Exception Location: /Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/utils/functional.py in inner, line 185

跟踪：

File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  111.                         response = callback(request, *callback_args, **callback_kwargs)
File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/contrib/auth/decorators.py" in _wrapped_view
  20.                 return view_func(request, *args, **kwargs)
File "/Users/nb/Desktop/spicestore/apps/avatar/views.py" in change
  76.             request.user.message_set.create(
File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/utils/functional.py" in inner
  185.         return func(self._wrapped, *args)

Exception Type: AttributeError at /avatar/change/
Exception Value: 'User' object has no attribute 'message_set'

此外，消息传递不再有效在网站上。 Django 1.4有哪些更改可能导致此问题，并且有人克服了类似的问题？

Also, messaging no longer works on the site. What are the changes in Django 1.4 that could be causing this and has anyone overcome a similar issue?

推荐答案

Django引入了消息应用程序1.2（发行说明）中，并弃用了旧用户消息API。

Django introduced a messages app in 1.2 (release notes), and deprecated the old user messages API.

在Django 1.4中，旧的message_set API已被完全删除，因此您必须更新代码。如果您遵循消息文档，您应该会发现它很简单

In Django 1.4, the old message_set API has been removed completely, so you'll have to update your code. If you follow the messages docs, you should find it pretty straight forward.
