Question

我在Django中定义了以下表单，我不知道为什么我无法从“save”方法中访问属性“username”：

class ExtendedUserForm(Form):

    required_css_class = 'required'

    username = forms.RegexField(regex=r'^[\w.@+-]+$', ...)

    def save(self, commit = False):

        User.objects.create_user(username = self.username, 
                                    email = self.email, 
                                    password = self.password1)

...每当我尝试访问它时，我都会遇到以下异常：

Exception Type: AttributeError
Exception Value: 'ExtendedUserForm' object has no attribute 'username'

我是Python的新手，尽管已经阅读了官方教程，但我并不完全理解Python类。任何帮助将不胜感激。

已清理的表单数据位于self.cleaned_data字典下。考虑username，email和password1是ExtendedUserForm的字段，您可以像这样写save：

def save(self, commit = False):
    User.objects.create_user(username = self.cleaned_data['username'], 
                                email = self.cleaned_data['email'], 
                                password = self.cleaned_data['password1'])

    return super(ExtendedUserForm, self).save(self, commit = commit)

Django使用self访问属性
