ruby-on-rails – Rails jQuery POST – ArgumentError – 参数

我已经设置了自定义控制器.我已经配置了以下路线：

resources :chats

我正在尝试使用jQuery向控制器发出post请求.这是代码：

$.post('/chats/',{ session: { advisor_id: $(this).attr('data-id') } },function (data) {
    eval(data);
});

编辑：这是我的控制器的代码 –

class ChatsController < ApplicationController

  def create
    #create the new session
    @session = Session.create(:advisor_id => session_params[:advisor_id],:session_type => @session.call!,:client_id => current_user.id)

  end

  private
    def session_params
     params[:session].permit(:advisor_id,:client_id,:session_type)
    end
end

编辑：这是我的模型的代码 –

class Session < ActiveRecord::Base
  enum session_type: [ :chat,:call ]
  belongs_to :client,:class_name => "User",:foreign_key => :client_id
  belongs_to :advisor,:foreign_key => :advisor_id
  has_many :instant_messages

  def self.obj_name(id)
    o = Session.find(id)
    "#{o.client.full_name} and #{o.advisor.full_name}"
  end
end

但是它会抛出一个错误：

为什么会抛出这个错误？如何让它接受请求？
