Question

我试图实现Rails API，我有两个模型：

事件

belongs_to :location   accepts_nested_attributes_for :location

位置
```
has_many :events
```

带

event = Event.all

我正在获取location_id其他数据，但我想显示location.name代替location_id以获取索引路径的API请求，即 localhost:3000/api/events。

目前我的回复是

[{"id":5,"name":"event420","description":"22","venue":"","contact":"","cost":"","created_at":"2015-07-01T05:49:22.738Z","updated_at":"2015-07-01T05:49:22.738Z","started_at":"2015-07-01T06:00:00.000Z","ended_at":"2015-07-01T06:30:00.000Z","owner_id":6,"city_id":null,"slug":"event420","clot_id":null,"location_id":10}]

而不是location_id：10我想要Location.name

请建议我，我该怎么做。

Answer 1

def index
    @events = Event.all
    respond_to do |format|
      format.html
      format.json { render :json => @events.to_json(:include => { :location => { :only => :name } }) }
    end
end

将此代码添加到events_controller

Rails API以JSON
