验证非活动用户 Django

如何解决验证非活动用户 Django

我正在寻找解决我的问题的方法。我有自定义用户模型：

class User(AbstractUser):
    username = models.CharField(max_length=150,unique=True,blank=False,null=False)
    first_name = models.CharField(max_length=150,blank=True)
    last_name = models.CharField(max_length=150,blank=True)
    password = models.CharField(max_length=150,blank=False)
    email = models.EmailField(unique=True,blank=False)
    date_create = models.DateTimeField(auto_now_add=True)
    address = models.CharField(blank=True,max_length=128)
    phone = PhoneNumberField(unique=True)
    photo = models.ImageField(upload_to='images/',blank=True)
    is_active = models.BooleanField(default=True)

在我的应用程序中，我有电子邮件确认。当我创建用户时，我点击了“is_active=False”。当用户激活帐户然后标记“is_active=True”。一切正常。但是当非活动用户尝试登录时，我想以登录形式从 Django 获取消息。 Django 有（源代码）：

def confirm_login_allowed(self,user):
        if not user.is_active:
            raise ValidationError(
                self.error_messages['inactive'],code='inactive',)

但对我不起作用。更新：当非活动用户尝试登录时，我收到与用户名或密码不正确的用户相同的消息。我试图覆盖 AuthenticationForm:

User = get_user_model()
class CustomAuthenticationForm(AuthenticationForm):
    class Meta:                # tried with Meta and without
        model = User
    def confirm_login_allowed(self,user):
        if not user.is_active:
            raise forms.ValidationError('There was a problem with your login.')

查看：

class CustomLoginView(SuccessMessageMixin,LoginView):
    form_class = CustomAuthenticationForm
    success_url = reverse_lazy('home')
    success_message = "You was logged in successfully"

网址：

path('login/',CustomLoginView.as_view(),name='login'),

更新、模板库和登录：

            </div>
        </form>
    </div>
</div>

有人可以帮我吗？谢谢。

解决方法

我是从安全角度理解的。我解决了它只是覆盖了 ModelBackend

from django.contrib.auth.backends import ModelBackend  
from django.contrib.auth import get_user_model 
UserModel = get_user_model()
class CustomModelBackend(ModelBackend):
    def authenticate(self,request,username=None,password=None,**kwargs):
        if username is None:
            username = kwargs.get(UserModel.USERNAME_FIELD)
        if username is None or password is None:
            return
        try:
            user = UserModel._default_manager.get_by_natural_key(username)
        except UserModel.DoesNotExist:
            # Run the default password hasher once to reduce the timing
            # difference between an existing and a nonexistent user (#20760).
            UserModel().set_password(password)
        else:
            if user.check_password(password):   # here (remove 'and self.user_can_authenticate(user):')
                return user

设置

AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend','accounts.backends.CustomModelBackend',]
