Django“AnonymousUser”对象没有属性“u meta”

django python

Luv33preet · 技术社区 · 8 年前

我在Django应用程序中使用社交登录。因此,我在我的 settings.py 文件

AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend',
    'social_core.backends.open_id.OpenIdAuth',
    'social_core.backends.google.GoogleOpenId',
    'social_core.backends.google.GoogleOAuth2',
    'social_core.backends.google.GoogleOAuth',
    'social_core.backends.twitter.TwitterOAuth',
    'social_core.backends.facebook.FacebookOAuth2',
    'social_core.backends.github.GithubOAuth2',

]

我还使用了 UserCreationForm

class SignupForm(UserCreationForm):
    first_name = forms.CharField(max_length=30, required=True, help_text='Required.')
    last_name = forms.CharField(max_length=30, required=True, help_text='Required.')
    email = forms.EmailField(max_length=254, help_text='Required. Inform a valid email address.')

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2' )

这是视图文件,

def signup(request):
    if request.method == 'POST':
        form  = SignupForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_pass = form.cleaned_data.get('password')
            user = authenticate(request, username=username, password=raw_pass)
            login(request,user,backend='django.contrib.auth.backends.ModelBackend')
            url = reverse('location:get_location')
            print("location_url ", url)
            return HttpResponseRedirect(url)
    else:
        form = SignupForm()
    return render(request, 'signup.html', {'form':form})

'AnonymousUser' object has no attribute '_meta'

login(request,user,backend='django.contrib.auth.backends.ModelBackend')

为什么会这样?

我可以在我的管理面板中看到用户已被保存。

是什么导致了这个错误?如何解决?

保存表单时,您已经拥有了用户,因此不需要调用 authenticate 因为您在调用时已经提供了后端 login()

user = form.save()
login(request, user, backend='django.contrib.auth.backends.ModelBackend')

来这里寻找这个错误。我们的堆栈是django oscar+wagtail。结果是我们删除了 oscar.apps.customer.auth_backends.EmailBackend AUTHENTICATION_BACKENDS . 把它放回去解决了这个问题。

如果您打印表单。清理完数据后,你会得到一个类似的字典

{'username': 'myuser', 'password1': 'pass1234', 'password2': 'pass1234'}

更改raw_传递线应该可以解决这个问题:

raw_pass = form.cleaned_data.get('password1')

abhishek Singh 6 年前

AUTHENTICATION_BACKENDS = ('django.contrib.auth.backends.ModelBackend',)

或者将后端传递给登录函数本身

login(request, username,password, backend='django.contrib.auth.backends.ModelBackend')

导入make_password函数并将密码从注册表中传递给它,然后它将以加密形式将密码保存到数据库中

from django.contrib.auth.hashers import make_password

raw_pass = form.cleaned_data.get('password') raw_pass = make_password(form.cleaned_data.get('password'))

Django=2.2.4

AUTH_USER_MODEL = 'myapp.MyUser' 设置。py以上 MIDDLEWARE .

2.2 Docs 替换自定义用户模型时:

“Django允许您通过提供引用自定义模型的AUTH\u user\u model设置值来覆盖默认用户模型: AUTH\u USER\u MODEL='我的应用程序。我的用户' . 这对虚线描述了Django应用程序的名称(必须在您安装的应用程序中),以及您希望用作用户模型的Django模型的名称。“

        user = userform.save()
        user.set_password(user.password)
        user.save()

我遇到了同样的问题,因为我有自定义的身份验证,并且传入了错误的参数 authenticate()

您没有共享您的自定义用户模型,但可能是您使用电子邮件作为 USERNAME_FIELD .

class User(AbstractUser):
    email = models.EmailField(unique=True)
    USERNAME_FIELD = 'email'

    if form.is_valid():
        form.save()
        email = form.cleaned_data['email']
        password = form.cleaned_data['password1']
        user = authenticate(request, email=email, password=password)
        login(request, user)
    ...
