你的表格应该是这样的。

def clean_email(self):
    email = self.cleaned_data.get('email')
    username = self.cleaned_data.get('username')
    print User.objects.filter(email=email).count()
    if email and User.objects.filter(email=email).count() > 0:
        raise forms.ValidationError(u'This email address is already registered.')
    return email
