Python django中通过电子邮件和数据库密码进行用户身份验证

我是django的初学者。我正在从事一个项目，在该项目中，客户和公司都有自己的帐户。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

但现在我无法使用超级用户凭据登录到管理页面。我应该怎么做

型号

考虑从

django.contrib.auth.models

扩展

User

模型，如下所示。如果不想这样做，请跳到下一节（身份验证）

用户

模型具有公共字段，例如

用户名

、

名字

、

姓氏

、

电子邮件

，等等。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

，这可能也适用于您

请在此处阅读更多信息：

认证

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：

一旦设置好，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.

上面的代码片段来自文档，我已经对其进行了修改，以适合您的用例

from django.contrib.auth.models import User

class Customer(User):
    # extra fields

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.
