ruby-on-rails – 对嵌套资源的PUT更新操作的RSpec控制器测试

我正在学习Rails以及如何使用RSpec进行测试.我需要帮助完成PUT更新操作的RSpec控制器测试.控制器指示嵌套资源.嵌套路由和相关程序代码在Web浏览器中按预期工作.我只需要帮助为PUT更新操作编写RSpec测试.我已经通过了控制器执行的其他操作的测试.

我知道路径以及父和子id必须传递给put方法,但我对以下内容感到困惑：(1)如何使用FactoryGirl对象正确设置PUT更新测试,以及(2)正确RSpec语法将路径和ID传递给PUT方法.

耙路线的相关路线：

PATCH  /members/:member_id/cardio_exercises/:id(.:format)      cardio_exercises#update
  PUT    /members/:member_id/cardio_exercises/:id(.:format)      cardio_exercises#update

routes.rb包含：
??????资源：成员做
????????资源：cardio_exercises
??????结束

members.rb包含：
??????has_many：cardio_exercises,：dependent => ：破坏

cardio_exercises.rb包含：
??????belongs_to：member

相关工厂：

FactoryGirl.define do
 factory :cardio_exercise do
   title "My cardio exercise"
   duration 30
   calories_burned 300
   date "2014-11-15"       
   association :member     
 end
end


FactoryGirl.define do
  factory :member do
    first_name {Faker::Name.first_name}
    last_name {Faker::Name.last_name}
    age 21
    height 75
    weight 195
    goal "fffff" * 5
    start_date "2014-11-15"     
  end
end

cardio_exercises_controller.rb

class CardioExercisesController < ApplicationController

# :get_member is defined in the private method at the bottom of this file,# and takes the member_id provided by the routing and
#converts it to a @member object.

before_action :get_member    

# GET member/1/cardio_exercises
# GET member/1/cardio_exercises.json
def index
@cardio_exercises = @member.cardio_exercises
end

# GET member/1/cardio_exercises/1
# GET member/1/cardio_exercises/1.json
def show
 cardio_exercise = @member.cardio_exercises.find(params[:id])
end

# GET member/1/cardio_exercises/new
def new
  @member = Member.find(params[:member_id])
  @cardio_exercise = @member.cardio_exercises.build
end

# GET member/1/cardio_exercises/1/edit
def edit
@cardio_exercise = @member.cardio_exercises.find(params[:id])
end

# POST member/1/cardio_exercises
# POST member/1/cardio_exercises.json
def create
@cardio_exercise = @member.cardio_exercises.build(cardio_exercise_params)

if @cardio_exercise.save
flash[:success] = "Cardio exercise was successfully created."
redirect_to member_cardio_exercises_path(@member)
else
render 'new'
end
end  

# PATCH/PUT member/1/cardio_exercises/1
# PATCH/PUT member/1/cardio_exercises/1.json
def update
 @cardio_exercise = @member.cardio_exercises.find(params[:id])
  if @cardio_exercise.update(cardio_exercise_params)
  flash[:success] = "Cardio exercise was successfully updated."
  redirect_to member_cardio_exercises_path(@member)
else
render 'edit'
end
end

# DELETE member/1/cardio_exercises/1
# DELETE member/1/cardio_exercises/1.json
def destroy
@cardio_exercise = @member.cardio_exercises.find(params[:id])
@cardio_exercise.destroy
respond_to do |format|
format.html { redirect_to (member_cardio_exercises_path(@member)),notice: 'Cardio exercise was    successfully destroyed.' }
format.json { head :no_content }
end
end

private
# The get_member action converts the member_id given by the routing
# into an @member object,for use here and in the view.

def get_member
@member = Member.find(params[:member_id])
end


def cardio_exercise_params
params.require(:cardio_exercise).permit(:title,:duration,:calories_burned,:date,:member_id)
end
end

cardio_exercises_controller_spec.rb和我尝试设置PUT更新操作的几个测试：

require 'rails_helper'

RSpec.describe CardioExercisesController,:type => :controller do
  before :each do
    @member = FactoryGirl.create(:member)      
    @cardio_exercise = FactoryGirl.create(:cardio_exercise,member: @member)      
    @cardio_exercise_attributes = FactoryGirl.attributes_for(:cardio_exercise,:member_id => @member)
    @cardio_exercise_update_attributes = FactoryGirl.attributes_for(:cardio_exercise,:title => "Your Cardio Exercise",:member_id => @member)
  end

describe "GET index" do
it "assigns all cardio_exercises as @member.cardio_exercises" do
  get :index,{ :member_id => @member  }
  expect(assigns(:cardio_exercises)).to eq(@member.reload.cardio_exercises)
end
end

describe "GET show" do
it "assigns the requested cardio_exercise as @cardio_exercise" do
  get :show,{ :member_id => @member,:id => @cardio_exercise }    
  expect(assigns(:cardio_exercise)).to eq(@cardio_exercise)  
end
end 

describe "GET new" do
 it "assigns a new cardio_exercise as @member.cardio_exercise" do
  get :new,{ :member_id => @member }
  expect(assigns(:cardio_exercise)).to be_a_new(CardioExercise)
end
end

 describe "GET edit" do
  it "assigns the requested cardio_exercise as @member.cardio_exercise" do      
  get :edit,:id => @cardio_exercise }
  expect(assigns(:cardio_exercise)).to eq(@cardio_exercise) 
 end
end

describe "POST create" do
  describe "with valid params" do
  it "creates a new CardioExercise" do        
    expect {          
      post :create,:cardio_exercise => @cardio_exercise_attributes }
    }.to change(CardioExercise,:count).by(1)         
  end

  it "assigns a newly created cardio_exercise as @cardio_exercise" do
    post :create,:cardio_exercise => @cardio_exercise_attributes }        
    expect(assigns(:cardio_exercise)).to be_a(CardioExercise)
    expect(assigns(:cardio_exercise)).to be_persisted
  end

  it "redirects to the created cardio_exercise" do
    post :create,:cardio_exercise => @cardio_exercise_attributes }
    expect(response).to redirect_to(member_cardio_exercises_path(@member))
  end
  end
 end

 describe "PUT update" do
  describe "with valid params" do

  it "updates the requested cardio_exercise" do
    put :update,:id => @cardio_exercise_update_attributes }
    @member.cardio_exercise.reload                      
    put :update,:id => @cardio_exercise_update_attributes}

  end

  it "assigns the requested cardio_exercise as @member.cardio_exercise" do
    put :update,:cardio_exercise => @cardio_exercise_update_attributes = FactoryGirl.attributes_for(:cardio_exercise,:member_id => @member)}
    expect(assigns(:cardio_exercises)).to eq(@member.cardio_exercises)
  end

  it "redirects to the cardio_exercise" do 
    put :update,:id => @cardio_exercise }        
    expect(response).to redirect_to(@member.cardio_exercise)
  end
 end

 describe "with invalid params" do
  xit "assigns the cardio_exercise as @member.cardio_exercise" do

  end

  xit "re-renders the 'edit' template" do

    expect(response).to render_template("edit")
  end
 end
end

describe "DELETE destroy" do
  it "destroys the requested cardio_exercise" do
  expect {
    delete :destroy,:id => @cardio_exercise }
  }.to change(CardioExercise,:count).by(-1)
  end

  it "redirects to the cardio_exercises list" do      
  delete :destroy,:id => @cardio_exercise }
  expect(response).to redirect_to(member_cardio_exercises_url)
  end
end
end

请查看我的测试设置和PUT更新测试.具体来说,我的设置是否是测试PUT更新操作的正确方法？

如何更改控制器更新操作的设置和/或测试,以便：

(1)我的测试与我的路由匹配更新操作？

(2)我用正确的RSpec语法传递必要的父和子id,以便找到记录？

我感谢任何帮助！

put :update,{ 
  :member_id => @member,:id => @cardio_exercise.id,:cardio_exercise => @cardio_exercise_update_attributes 
}
