如何通过django的手机号码或电子邮件地址登录？

Question

我最初用电子邮件和密码登录，但现在想改变它，以便我们可以使用手机号码或电子邮件地址和密码登录。我无法了解我的代码中要更改哪些部分，因为我不想删除已经存在的用户和数据。

forms.py

from django.contrib.auth.models import User 
from django import forms 


class UserForm(forms.ModelForm): 
    password = forms.CharField(widget=forms.PasswordInput) 

    class Meta: 
     model = User 
     fields = ['first_name', 'last_name', 'email', 'password'] 

views.py

class UserFormView(View): 

    form_class = UserForm 
    template_name = 'main/registration_form.html' 

    def get(self, request): 
     form = self.form_class(None) 
     return render(request, self.template_name, {'form': form}) 

    def post(self, request): 
     form = self.form_class(request.POST) 

     if form.is_valid(): 

      user = form.save(commit=False) 

      # cleaned (normalized) data 
      email = form.cleaned_data['email'] 
      password = form.cleaned_data['password'] 
      user.username = email 
      user.set_password(password) 
      user.save() 

      # return user objects if credentials are correct 
      user = authenticate(username=email, password=password) 

      if user is not None: 

       if user.is_active: 
        login(request, user) 
        # request.user.username  display their username 
        return redirect('main:register2') 
     return render(request, self.template_name, {'form': form}) 

class LoginForm(View): 

    form_class = UserForm 
    template_name = 'main/login_form.html' 

    def get(self, request): 
     form = self.form_class(None) 
     if error: 
      return render(request, self.template_name, {'form': form}, 
{'error': error}) 
     else: 
      return render(request, self.template_name, {'form': form}) 

    def post(self, request): 
     email = request.POST.get('email', '') 
     password = request.POST.get('password', '') 
     user = auth.authenticate(username=email, password=password) 

     if user is not None and user.is_active: 
      # Correct password, and the user is marked "active" 
      auth.login(request, user) 
      # Redirect to a success page. 
      return HttpResponseRedirect("/main/home/") 
     else: 
      # Show an error page 
      error = True 
      return HttpResponseRedirect("/main/", {'error': error}) 

请回答考虑到我是新来的Django的事实。在此先感谢:)

在您的视图的后期方法中，确定用户给你什么。如果是电子邮件，请用电子邮件提供Django的authenticate()方法。如果不是，则假定它是一个电话号码（您也可以在那里运行其他验证），并在验证过程中使用它。

另一种方法是创建一个自定义authenticate()方法，它应该是这样的：

from django.contrib.auth.backends import ModelBackend 


class MobilePhoneOrEmailModelBackend(ModelBackend): 

    def authenticate(self, username=None, password=None): 
     # the username could be either one of the two 
     if '@' in username: 
      kwargs = {'email': username} 
     else: 
      kwargs = {'mobile_phone': username} 
     try: 
      user = User.objects.get(**kwargs) 
      if user.check_password(password): 
       return user 
     except User.DoesNotExist: 
      return None 

    def get_user(self, username): 
     try: 
      return User.objects.get(pk=username) 
     except User.DoesNotExist: 
      return None 

让我知道如果这个工作进行的顺利吗。
