python - django 中的身份验证

Question

我正在尝试在我的 django 网站上连接表单

如果在 shell 中，我会这样做:

$ ./manage.py shell
Python 2.6.4 (r264:75706, Oct 27 2009, 06:25:13) 
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.contrib import auth
>>> user = auth.authenticate(username='user', password='password')
>>> 

如你所见，没问题

但如果按照我的观点，我有:

# views.py
...
from django.contrib import auth
...

def check_pass(request):
    ...
    user = auth.authenticate(username='user', password='password')
    ...

我有一个带有堆栈跟踪的 500 错误页面:

Environment:

Exception Type: OperationalError at /check_pass/
Exception Value: no such table: auth_user

我的设置.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
)
...
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
)

我已经在没有任何更改的情况下运行了“syncdb”，我确信这是这一行的问题，因为我用

assert False
user = auth...

断言错误

user = auth...
assert False

没有这样的表auth_user

这对我有用:

在脚本的顶部:

from django.contrib.auth import authenticate, login, logout

身份验证:

 user = authenticate(username=request.POST['username'], password=request.POST['password'])
        if user is not None:
            if user.is_active:
                login(request, user)
                #user is loged in
            else:
                # user is not active
        else:
            # false authentification

我希望它对你有用:)
