Rails复制了资源内部的参数 [英] Rails duplicated the parameters inside the resource

问题描述

我正在使用Angular Resource，但我不明白为什么Rails复制参数并将其放在资源名称中.我只需要了解为什么会发生这种情况.

I am using the Angular Resource and I don't understand why Rails duplicated the parameters and put it inside the resource name. I just need to understand why this is happening.

// post data
{"title":"asdsad"}

// rails parameters 
Parameters: {"title"=>"asdsad", "presentation"=>{"title"=>"asdsad"}}

重复，因为欢迎来到Stackoverflow，在这里您需要50点评论，因此会发生这种情况.我真的很抱歉: AngularJS $ resource发送了一个额外的注册"消息；哈希?

Duplicate because welcome to Stackoverflow where you need 50 points to comments so this happen. I really so sorry: AngularJS $resource sending out an extra "registration" hash?

推荐答案

..如果已在初始化程序中打开config.wrap_parameters [请检查文件 config/initializers/wrap_parameters.rb]或[您]正在呼叫 控制器中的wrap_parameters()...参数将被克隆并 默认情况下，根据您的控制器名称将其包装在密钥中.

..if you've turned on config.wrap_parameters in your initializer [check the file config/initializers/wrap_parameters.rb] or [you] are calling wrap_parameters() in your controller...the parameters will be cloned and wrapped in the key according to your controller's name by default.

换句话说，您所看到的是Rails在params哈希中输入内容的默认方式.

In other words, what you are seeing is the default way rails enters things in the params hash.
