Question

我试图从旧项目中重复使用代码进行注册表单。问题是Django说UserCreationForm没有clean_password1属性。

你知道问题出在哪里吗？我看到UserCreationForm中没有这样的属性，但它之前有效。

我该怎么做才能让它发挥作用？

编辑：因为它调用超级（...）。clean_password1，它不是超级类。所以我试图把super（...）。更名为clean_data.get（＆＃34; password1＆＃34;），但它引发了clean_data不存在的错误（在超类中）。

class UserProfileCreationForm(UserCreationForm):
    username = forms.CharField(label="Username", max_length=40, min_length=5)
    email = forms.EmailField(label="Email address", max_length=40)
    first_name = forms.CharField(label='First name', max_length=40, required=False)
    last_name = forms.CharField(label='Last name', max_length=40, required=False)

    password1 = forms.CharField(label="Password", widget=forms.PasswordInput, min_length=5)
    password2 = forms.CharField(label="Password confirmation", widget=forms.PasswordInput)

    class Meta():
        model = UserProfile
        fields = (
            'username', 'email', 'type_of_user', 'first_name', 'last_name', 'password1', 'password2','IBAN',

        )

    def clean_password1(self):
        password = self.cleaned_data.get('password1')
        if len(password) < 8:
            raise ValidationError('Password has to be of size at least 8 characters')
        return super(UserProfileCreationForm, self).clean_password1()

    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("Password mismatch")
        return password2

    def save(self, commit=True):
        try:
            with transaction.atomic():
                user = User(username=self.cleaned_data['username'],
                            first_name=self.cleaned_data['first_name'],
                            last_name=self.cleaned_data['last_name'],
                            email=self.cleaned_data['email'])
                user.save()
                user.set_password(self.cleaned_data["password1"])

                user_profile = UserProfile(user=user,
                                           IBAN=self.cleaned_data['IBAN'],
                                           type_of_user=self.cleaned_data['type_of_user']
                                           )
                user_profile.save()
        except:
            raise #TODO: HANDLE THE EXCEPTION

        return user

Answer 1

您可以安全地删除$json = file_get_contents('json.php'); $itemsArray = json_decode($json); print_r($itemsArray); - Django已经验证密码是否匹配（我假设您正在使用新项目的当前版本）。至于clean_password2我建议将其删除并阅读password validation上的文档（Django 1.9中的新内容）。

Answer 2

没有理由在clean_field方法中调用super;该字段不存在于基类中，因此clean_field也不存在。

＆＃39;超＆＃39;对象没有属性＆＃39; clean_password1＆＃39;
