Django confirm_email和confirm_password返回None

Question

我有一个看起来像这样的表单。

class MyForm(Form):
    first_name = forms.CharField(max_length=128,
                                 widget=forms.TextInput(attrs={
                                     'placeholder': 'First Name',
                                     'class': "form-control"}),)
    last_name = forms.CharField(max_length=128,
                                widget=forms.TextInput(attrs={
                                    'placeholder': 'Last Name',
                                    'class': "form-control"}),)

    email = forms.EmailField(max_length=128,
                             widget=forms.TextInput(attrs={
                                 'placeholder': 'Email',
                                 'class': "form-control"}),)

    confirm_email = forms.EmailField(max_length=128,
                                     widget=forms.TextInput(attrs={
                                         'placeholder': 'Confirm Email',
                                         'class': "form-control"}),)

    password = forms.CharField(max_length=128,
                               widget=forms.PasswordInput(attrs={
                                   'placeholder': 'Password',
                                   'class': "form-control"}),)

    confirm_password = forms.CharField(max_length=128,
                               widget=forms.PasswordInput(attrs={
                                   'placeholder': 'Confirm Password',
                                   'class': "form-control"}),)

    def clean_email(self):
        cleaned_data = super(MyForm, self).clean()
        email = cleaned_data.get('email')
        confirm_email = cleaned_data.get('confirm_email')

        if not confirm_email:
            raise forms.ValidationError("Please confirm your email.")

        if email and confirm_email:
            if email != confirm_email:
                raise forms.ValidationError("Emails do not match")
        return confirm_email

    def clean_password(self):
        cleaned_data = super(MyForm, self).clean()

        pwd = cleaned_data.get('password')
        cpwd = cleaned_data.get('confirm_password')

        if not cpwd:
            raise forms.ValidationError("Please Confirm your Password")
        if pwd and cpwd:
            if pwd != cpwd:
                raise forms.ValidationError("Passwords do not match.")  #CNone

        return cpwd

    def clean(self, *args, **kwargs):
        self.clean_email()
        self.clean_password()
        return super(MyForm, self).clean()

confirm_email和confirm_passwor%d字段都返回None，这使得这些字段无法验证。我几乎不知道是什么导致了这个问题。

这是我的表单的问题，还是更可能是视图甚至模板的问题？
