Charfield必须与另一个Charfield Django的表单验证匹配

Question

您好我无法找到一个验证，一个charfield必须与另一个charfield

比如我想这NEW_PASSWORD必须confirm_new_password匹配验证匹配的文档：

class ChangePassword(forms.Form): 
    new_password = forms.CharField(label='New Password', max_length=100, error_messages={'required': 'New password is required'}, widget=forms.PasswordInput()) 
    confirm_new_password = forms.CharField(label='Confirm New Password', max_length=100, error_messages={'required': 'Confirm New password is required'}, widget=forms.PasswordInput()) 

https://docs.djangoproject.com/en/1.9/ref/forms/fields/#charfield

看来主要的有required, max_length, min_length？

执行自定义表单验证，你需要重写洁（）函数，就像这样：

class ChangePassword(forms.Form): 
    new_password = forms.CharField(label='New Password', max_length=100, error_messages={'required': 'New password is required'}, widget=forms.PasswordInput()) 
    confirm_new_password = forms.CharField(label='Confirm New Password', max_length=100, error_messages={'required': 'Confirm New password is required'}, widget=forms.PasswordInput()) 

    def clean(self): 
     password = self.cleaned_data['new_password'] 
     confirm_password = self.cleaned_data['confirm_new_password'] 
     if password != confirm_password: 
      raise forms.ValidationError('Your passwords do not match!')
