url.py views.py Forms.py 其他资料 我转到

C:\Users\mittr\Desktop\ML Assignments\mom\Lib\site packages\django\views\generic\edit.py

，我看到第33行有以下内容：

`return form_class(**self.get_form_kwargs())`

当我将此更改为

返回表单_class（）

时，注册页面成功显示。然而，我相信这不是做生意的最佳方式

此外，forms.py文件中的save（）方法从未执行过，因此用户从未保存在自定义用户模型中。您的视图设置为使用UserRegistrationForm，但您的表单为UserRegistrationPerform

据推测，UserRegisterPerform是一个单独的表单，它不是modelform，也没有自定义的保存方法。您应该更改视图以指向正确的窗体

class RegisterView(CreateView):
    form_class = UserRegistrationForm
    template_name = 'registration/register.html'
    success_url = '/'

    def dispatch(self, *args, **kwargs):
        if self.request.user.is_authenticated:
            return redirect('/login')
        else:
            return super(RegisterView, self).dispatch(*args, **kwargs)

class UserRegisterForm(forms.ModelForm):

    password1 = forms.CharField(widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Email'}))
    password2 = forms.CharField(widget=forms.PasswordInput(attrs={'class': 'form-control', 'placeholder': 'Email'}))

    class Meta:
        model = User
        fields = ['email', 'full_name']

    def clean_password2(self):
        password1 = self.cleaned_data.get('password1')
        password2 = self.cleaned_data.get('password2')

        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords do not match.")
        else:
            return password2

    def clean_email(self):
        email = self.cleaned_data.get('email')
        qs = User.objects.get(email__iexact=email)
        if qs.exists():
            raise forms.ValidationError("A user with this email already exists.")
        else:
            return email

    def save(self, commit=True):
        user = super(UserRegisterForm, self).save(commit=False)
        user.set_password(self.cleaned_data['password1'])
        user.is_active = False

        if commit:
            user.save()
        return user

`return form_class(**self.get_form_kwargs())`
