Ruby on rails 保存mongoid模型,ruby-on-rails,mongodb,mongoid,Ruby On Rails,Mongodb,Mongoid,我使用了以下mongoid模型： class Exercise include Mongoid::Document field :name, :type => String field :description, :type => String belongs_to :group validates_presence_of :name, :description end 我想通过控制器持久化模型： class ExercisesController <

我使用了以下mongoid模型：

class Exercise
  include Mongoid::Document
  field :name, :type => String
  field :description, :type => String

  belongs_to :group

  validates_presence_of :name, :description
end

我想通过控制器持久化模型：

class ExercisesController < ApplicationController
  respond_to :json

  def create
    @exercise = Exercise.create(params[:exercise])
    @exercise.save!
    respond_with @exercise
  end
end

我得到这个错误：

失败/错误：post:create，：exercise=>exercise.to_json 命名错误：未定义的方法“拒绝”#

有人能看出我做错了什么吗？就这样传过去

params[:excercise] = JSON.parse("{\"_id\":\"50064f2e26a31829ca000001\",\"description\":\"Do something\",\"group_id\":\"4fbc6f5a26a3181742000004\",\"name\":\"Preacher curls\"}")
