我试图通过POST来创建一个用户资源与Django的tastypieDjango的 - TastyPie不能关键词解析成场
型号：
- 用户配置
- 用户（从django.contrib.auth。型号）
资源：
- CreateUserResource
- UserResource
- UserProfileResrouce
我不断收到错误
无法解析关键词 '城市' 到现场。选项包括：API_KEY，date_joined，电子邮件，FIRST_NAME，组ID，IS_ACTIVE，is_staff，is_superuser，LAST_LOGIN，姓氏，logentry，密码，个人资料，等级，user_permissions，用户名
我是新来的Django tastypie但在我的代码或django/tastypie代码的跟踪中找不到错误。它为什么这样做？ 我的代码是基于这个博客文章：http://psjinx.com/programming/2013/06/07/so-you-want-to-create-users-using-djangotastypie/
谢谢大家提前！
