Question

我有以下注册视图进入新用户.我希望它进入新用户然后自动登录.它通过用户记录保存,但在尝试登录时返回此错误:'AnonymousUser'对象没有属性'后端'

views.py

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST, error_class=DivErrorList)
        if form.is_valid():
            form.save()
            new_user = authenticate(username=request.POST['username'],password=request.POST['password'])
            login(request, new_user)
            return HttpResponseRedirect('/production/')
    else:
        form = UserRegisterForm(error_class=DivErrorList)

    return render(request,'register.html', {
        'form': form,
    })

forms.py

class UserRegisterForm(forms.ModelForm):

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

    password_compare = forms.CharField(max_length=128)

    def __init__(self, *args, **kwargs):
        super(UserRegisterForm, self).__init__(*args, **kwargs)
        self.fields['password_compare'].label = 'Password Again'
        self.fields['password'].help_text = ''
        self.fields['first_name'].label = 'First Name'
        self.fields['last_name'].label = 'Last Name'
        self.fields['email'].label = 'E-mail Address'

    def clean(self):
        cleaned_data = self.cleaned_data
        password1 = cleaned_data.get('password', None)
        password2 = cleaned_data.get('password_compare', None)
        if not (password1):
            error_msg = u'This field is required.'
            self._errors['password'] = self.error_class([error_msg])
        if not (password2):
            error_msg = u'This field is required.'
            self._errors['password_compare'] = self.error_class([error_msg])
        # password fields must match
        if password1 != password2:
            error_msg = u'Password doesn\'t match the confirmation.'
            self._errors['password'] = self.error_class([error_msg])
            del cleaned_data['password']
        # cannot have a username already existing
        try:
            existing_user = User.objects.get(username=cleaned_data.get('username'))
            error_msg = u'Username already exists.'
            self._errors['username'] = self.error_class([error_msg])
            del cleaned_data['username']
            return cleaned_data
        except User.DoesNotExist:
            return cleaned_data

您的用户永远不会进行身份验证,因为您以纯文本格式保存密码 - 并且authenticate需要使用哈希密码.您应该user.set_password(password)在将新创建的用户对象保存到db之前调用它 - 请参阅内置的UserCreationForm.
