我是django的初学者 . 我正在开展一个项目，其中客户和公司拥有自己的帐户models.py是：

class Company_SignUp(models.Model):
   comp_name = models.CharField(_('Company Name'), max_length=30)
   email = models.EmailField(_('E-mail'), unique=True)
   raise forms.ValidationError("This email address already exists.")
   password1 = models.CharField(_('Password'), max_length=128)
   password2 = models.CharField(_('Confirm Password'), max_length=30)

   def __unicode__(self):
       return smart_unicode(self.comp_name)

class Customer_SignUp(models.Model):
   cust_name = models.CharField(_('Customer Name'), max_length=30)
   email = models.EmailField(_('E-mail'), unique=True)
   password1 = models.CharField(_('Password'), max_length=128)
   password2 = models.CharField(_('Confirm Password'), max_length=30) 

   def __unicode__(self):
       return smart_unicode(self.cust_name)

我的forms.py是：

class Company(forms.ModelForm):
    class Meta:
        model = Company_SignUp
        widgets = {
          'password1': forms.PasswordInput(),
          'password2': forms.PasswordInput(),
        }
        fields = ('email','password1','password2','comp_name')

    def clean(self):
        if 'password1' in self.cleaned_data and 'password2' in       self.cleaned_data:
            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError(_("The two password fields did not match."))
            elif len(self.cleaned_data['password1']) < 8:
                raise forms.ValidationError(_("The password must be 8 characters long."))

        return self.cleaned_data

class Customer(forms.ModelForm):
    class Meta:
        model = Customer_SignUp
        widgets = {
            'password1': forms.PasswordInput(),
            'password2': forms.PasswordInput(),
        }  
    def clean(self):
        if 'password1' in self.cleaned_data and 'password2' in self.cleaned_data:
            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError(_("The two password fields did not match."))
            elif len(self.cleaned_data['password1']) < 8:
              raise forms.ValidationError(_("The password must be 8 characters long."))

        return self.cleaned_data

我将如何使用他们的电子邮件和密码验证公司或客户 . 我试过authenticate（）但它不起作用 . 如何在注册期间检查，给出的电子邮件地址已经存在

好吧，现在我创建了一个后端，它是：来自django.contrib.auth.models从prmanager.models导入用户导入Company_SignUp，Customer_SignUp

class EmailBackend(object):
    def authenticate(self, username=None, password=None):
        try:
            o = Company_SignUp.objects.get(email=username, password1=password)
        except Company_SignUp.DoesNotExist:
            try:
                o = Customer_SignUp.objects.get(email=username, password1=password)
            except Customer_SignUp.DoesNotExist:
                return None
        return User.objects.get(email=o.email)
   def get_user(self, user_id):
       try:
          return User.objects.get(pk=user_id)
       except User.DoesNotExist:
           return None

但现在我无法使用超级用户凭据登录管理页面 . 我该怎么办

python django authentication login

    Models

    考虑从 django.contrib.auth.models 扩展 User 模型 . 如果您不想这样做，请跳到下一部分（身份验证） .

    from django.contrib.auth.models import User

class Customer(User):
    # extra fields

    User 模型具有常见字段，例如 username ， first_name ， last_name ， email 等 . 您只需指定模型可能具有的任何额外属性 .

    Django文档建议扩展 AbstractBaseUser ，这也可能适合你 .

    在这里阅读更多：https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#extending-the-existing-user-model

    Authentication

    对于基于电子邮件的身份验证，您需要编写自己的身份验证后端：https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#writing-an-authentication-backend

    准备好后，您需要接受电子邮件/密码并使用 authenticate 和 login 进行身份验证 .

    from django.contrib.auth import authenticate, login

def my_view(request):
    email = request.POST['email']
    password = request.POST['password']
    user = authenticate(email=email, password=password)
    if user is not None:
        if user.is_active:
            login(request, user)
            # Redirect to a success page.
        else:
            # Return a 'disabled account' error message
    else:
        # Return an 'invalid login' error message.

    上面的代码段来自文档，我修改了它以适合您的用例 .
