Ruby on rails 聊天室消息控制器中的NoMethodError

我正在做一个AJAX调用，如下所示，并尝试解析Rails中接收到的JSON，如下所示

AJAX

local_data = {chat:{room_name: chatRoomName ,message: message}}
      $.ajax({
        type: "POST",
        url: '/chat_notify',
        dataType: 'json',
        async : false,
        data: local_data,
        success: function(data) {
            alert("working");
        }
      });

红宝石

def notify
    #data = ActiveSupport::JSON.decode(params)

    #chat_room = ChatRoom.where(:slug =>  data.chat.name)
    #puts @chat_room

    puts params.chat
    RestClient.post 'https://api.pushbots.com/push/all',
    { "platform" => [0,1] ,
      "msg" => "Harsha sent a message." ,
      "sound" => "pulse",
      "alias" => "harsha@mink7.com",
      "badge" => "1",
      "payload" => { "type" => "Chat", "chat_id" => 1 } }.to_json,
      headers = { "x-pushbots-appid" => APP_CONFIG['PUSHBOTS_APPID'],
                  "x-pushbots-secret" => APP_CONFIG['PUSHBOTS_SECRET'],
                  :content_type => :json }

    render json: true
  end

错误

您需要粘贴错误跟踪

但我认为问题可能出在下面

put params.chat

对于

参数

，没有聊天方法，只需将其删除即可

或

…..“有效负载”=>{“类型”=>“聊天”，“聊天id”=>1}}。到json

---

您需要

require'json'

才能使

可用。要使json

可用，请显示错误信息
