django注册查看无法正常工作

Question

我想创建一个注册视图，所以它需要用户名，密码和电子邮件注册，我使用Django用户模型，但它给我一个错误。

AttributeError at /signup/ 
'SignUpForm' object has no attribute 'cleaned_data' 

请告诉我如何解决这个问题，

forms.py

class SignUpForm(forms.Form): 
    username = forms.CharField(widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'})) 
    email = forms.EmailField(widget=forms.EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email'})) 
    password = forms.CharField(widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Password'})) 
    confirm_password = forms.CharField(widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 
     'Confirm Password'}), label="Confirm Password") 

    class Meta: 
     model = User 

    def __init__(self, *args, **kwargs): 
     super(SignUpForm, self).__init__(*args, **kwargs) 
     self.fields['username'].validators.append(ForbiddenUsernamesValidator) 
     self.fields['username'].validators.append(InvalidUsernameValidator) 
     self.fields['username'].validators.append(UniqueUsernameIgnoreCaseValidator) 
     self.fields['email'].validators.append(UniqueEmailValidator) 

    def clean(self): 
     super(SignUpForm, self).clean() 
     password = self.cleaned_data.get('password') 
     confirm_password = self.cleaned_data.get('confirm_password') 
     if password and password != confirm_password: 
      self._errors['password'] = self.error_class(['Passwords don\'t match']) 
     return self.cleaned_data 

views.py

def signup(request): 
    if request.method == 'POST': 
     form = SignUpForm(request.POST or None) 
     if form.is_valid(): 
      username = form.cleaned_data.get('username') 
      password = form.cleaned_data.get('password') 
      email = form.cleaned_data.get('email') 
      print(username) 
      print(password) 
      print(email) 
      messages.add_message(request, messages.SUCCESS, 'YOU ARE REGISTRED SUCCESSFULLY') 
      return render(request, 'authentication/signup.html', {}) 
     else: 

      return render(request, 'authentication/signup.html', {'form': form}) 
    else: 
     return render(request, 'authentication/signup.html', {'form': SignUpForm})

def clean(self): 
     self.cleaned_data = super(SignUpForm, self).clean() 
     password = self.cleaned_data.get('password') 
     confirm_password = self.cleaned_data.get('confirm_password') 
     if password and password != confirm_password: 
      self._errors['password'] = self.error_class(['Passwords don\'t match']) 
     return self.cleaned_data
