Python Django:获取一个错误，即SignUpForm没有属性clean_数据

这是东西。我不确定哪一部分出了问题。请帮帮我我有点困惑哈哈哈

class SignUpForm(forms.ModelForm):
    fname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'First Name','required':True}))
    lname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'Last Name','required':True}))
    email = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Email','required':True}))
    emailConfirm = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Confirm email','required':True}))
    password = forms.CharField(max_length=256, label="", required=True, widget=forms.PasswordInput(attrs={'class': 'form-control','placeholder': 'Password','required':True}))
    datetime = forms.DateTimeInput()
    class Meta:
        model=SignUp
        fields=['fname','lname','email','password',]

    def clean_fname(self):
        name = self.clean_data.get('fname')
        if ' ' in name:
            raise forms.ValidationError("Please do not have a space in your name.")
        else:
            return name

没错，没有属性clean_数据可能会帮助您…

以前的django版本中使用了clean_数据，而不是使用clean_数据

你的问题会解决的

这不正是错误告诉你的吗？类SignUpForm没有名为clean_data的属性。但代码却试图访问它？
