Question

我在django 1.6中使用过代码但是在django 1.8.6中尝试时我得到了：

AttributeError: 'SignupDataForm' object has no attribute 'fields'

在这一行，但每当要求领域时也是如此：

 merged_field_order = list(self.fields.keys())

我的SignupDataForm是一个声明如下的子项：

class SignupDataForm(BaseUserDataForm):
    reg_user_badge = forms.CharField(label="Give Points to a Friend",required=False,widget = TextInput(attrs={'placeholder': 'Username (optional)'}),validators=[validate_friendname])

class Meta(BaseUserDataForm.Meta):
    model = UserData
    fields = BaseUserDataForm.Meta.fields + ('terms_conditions',)
    #terms_conditions is also a model field but not added to the parent definition

def __init__(self, *args, **kwargs):
    super(SignupDataForm, self).__init__(*args, **kwargs)
    self.fields['terms_conditions'].required = False
    self.fields['gender'].widget = Select(choices=GENDER_CHOICES,attrs={'class':'signup_select',})
    self.fields['password2'].widget.attrs['onblur'] ="check_pass()"
    self.fields['password1'].widget.attrs['onblur'] ="check_pass()"


def clean(self):
    #clean overwrite

奇怪的是，如果我使用父表单，一切正常，我没有错误。此外，如果我在META声明中放置一个打印字段，那么带有字段的元组就在那里。父母的短代码在这里：

class BaseUserDataForm(forms.ModelForm):
    url = forms.CharField(max_length = 30, label="Don't type here (anti spam protection)",validators=[validate_name_honeypots])

class Meta:
    model = UserData
    fields = ('****model fields named without terms_conditions field****')

def __init__(self, *args, **kwargs):
    super(BaseUserDataForm, self).__init__(*args, **kwargs)

错误发生在另一个孩子身上：

class BaseSignupForm(SignupDataForm):
    username = forms.CharField(label=_("Username"),
                           max_length=get_username_max_length(),
                           min_length=app_settings.USERNAME_MIN_LENGTH,
                           widget=forms.TextInput(
                               attrs={'placeholder':
                                      _('Username'),
                                      'autofocus': 'autofocus'}))
    email = forms.EmailField(widget=forms.TextInput(
    attrs={'type': 'email',
           'placeholder': _('E-mail address')}))

    def __init__(self, *args, **kwargs):
        email_required = kwargs.pop('email_required',
                                app_settings.EMAIL_REQUIRED)
        self.username_required = kwargs.pop('username_required',
                                        app_settings.USERNAME_REQUIRED)
        super(BaseSignupForm, self).__init__(*args, **kwargs)
        # field order may contain additional fields from our base class,
        # so take proper care when reordering...
        field_order = ['email', 'username']

        merged_field_order = list(self.fields.keys())

有人知道我做错了什么吗？

更新 - 解决：解决了。根本不是python ModelForm或allauth问题。下面有一个表格，部分包装和部分评论，我没有看到，它引起了一个意图错误，表明它是如此奇怪的方式......
