AttributeError: Got AttributeError when attempting to get a value for field `password2` on serializer ` UserSerializer`...

Error_msg:

AttributeError: Got AttributeError when attempting to get a value for field `password2` on serializer `        UserSerializer`.
        The serializer field might be named incorrectly and not match any attribute or key on the `User` instance.
        Original exception text was: 'User' object has no attribute 'password2'.
        ERROR basehttp 124 "POST /users/ HTTP/1.1" 500 20189

问题:

　　序列化器字段读写设置出错

解决:

　　serializer中没有write_only_fields关键字, 需要在字段中加write_only=True
