Question

尝试在Django 2.0中使用自定义用户模型注册用户时，出现以下错误。

public ActionResult Index()
    {
        var users = db.Users.Select().Where(u => u.Users1).ToList();
        return View(users);
    }

Urls.py

    success_url = '/'

    def dispatch(self, *args, **kwargs):
        if self.request.user.is_authenticated:

其他信息

我接着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 ，我看到第33行有以下内容：

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

当我将其更改为`return form_class(**self.get_form_kwargs())` 时，注册页面成功显示。但是，我认为这不是开展业务的最佳方式。

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。任何有关这方面的帮助也将受到赞赏。

Answer 1

您的视图设置为使用UserRegistrationForm，但您的表单是UserRegisterForm。

据推测，UserRegisterForm是一个单独的表单，它不是一个modelform，也没有自定义的save方法。您应该将视图更改为指向正确的形式。
