Rails RestKit POST请求缺少json的根类

Question

嗨伙计们,我有这个我修复过的问题,但我知道修复是没有做正确的方法.有人能指出我正确的方向进行正确的修复吗？

所以基本上我用iOS sim创建一个对象,RESTkit postObject我收到了这条消息

Processing PeopleController#create (for 127.0.0.1 at 2012-01-13 03:55:46) [POST]
  Parameters: {"name"=>"data"}

Person Create (0.4ms)   INSERT INTO "people" ("created_at", "updated_at", "name")
VALUES('2012-01-13 11:55:46', '2012-01-13 11:55:46', NULL)
Completed in 27ms (View: 1, DB: 0) | 200 OK 

一位优秀的先生们指出,我的创建函数中的类只接受了一个我忽略的人类.

def create
@person = Person.new(params[:person]) , thus looking for {"person" => {"name"=>"data"}}

我这样做了

@person =Person.new(name:=>params[:name])因为我现在只发送{"name"=>"data"} 它创建好,我可以看到我的ios sim上的条目,但我知道这不是正确的方式应该{"person" => {"name"=>"data"}}发送到原始功能的正确方法.加上我的错误找不到keyPath的对象映射:"有什么想法吗？提前thnx!这是我的xcode
