Ruby on Rails 4:使用rspec无法测试嵌套资源 [英] Ruby on Rails 4: test nested resources with rspec not working
问题描述
我在测试我的ruby on rails应用程序时遇到了一些麻烦.我有一个资源餐厅和一个嵌套资源菜单.
i have some troubles with testing my ruby on rails application. I have a resource Restaurant and a nested resource menu.
路由文件:
resources :restaurants do
resources :menus
菜单模型:
class Menu
include Mongoid::Document
belongs_to :restaurant
accepts_nested_attributes_for :restaurant
validates :name, presence: true
validates :description, presence: true
validates :restaurant, presence: true
field :name, type: String
field :description, type: String
end
餐厅模型:
class Restaurant
include Mongoid::Document
has_one :address, dependent: :destroy
has_many :menus, dependent: :destroy
accepts_nested_attributes_for :address, :menus
validates :name, presence: true
validates :description, presence: true
validates :address, presence: true
field :name, type: String
field :description, type: String
field :thumbnail, type: String
field :banner, type: String
end
然后,我正在尝试类似的方法.这是rspec的默认测试,但由于我有嵌套的资源,因此我试图对其进行修改.
then, i am trying something like this. it is a default test from rspec, but which i am trying to modify because i had a nested resource..
describe MenusController do
before :each do
@restaurant = FactoryGirl.create(:random_restaurant)
@menu = FactoryGirl.create(:menu)
end
describe 'GET index' do
it 'assigns all menus as @menus' do
get restaurant_menus_path(@restaurant)
assigns(:menus).should eq([menu])
end
end
describe 'GET all restaurants menus' do
it 'responds with 200' do
get :index, { :id => @restaurant }
expect(response).to be_success
expect(response.status).to eq(200)
end
end
但错误是:
1) MenusController GET index assigns all menus as @menus
Failure/Error: get restaurant_menus_path(@restaurant)
ActionController::UrlGenerationError:
No route matches {:controller=>"menus", :action=>"/en/restaurants/52a20e4c6561721131010000/menus"}
# ./spec/controllers/menus_controller_spec.rb:30:in `block (3 levels) in <top (required)>'
2) MenusController GET all restaurants menus responds with 200
Failure/Error: get :index, { :id => @restaurant }
ActionController::UrlGenerationError:
No route matches {:action=>"index", :id=>"52a20e4c6561721131060000", :controller=>"menus"}
# ./spec/controllers/menus_controller_spec.rb:37:in `block (3 levels) in <top (required)>'
以下是路线:
restaurant_menus_path GET (/:locale)/restaurants/:restaurant_id/menus(.:format) menus#index
POST (/:locale)/restaurants/:restaurant_id/menus(.:format) menus#create
new_restaurant_menu_path GET (/:locale)/restaurants/:restaurant_id/menus/new(.:format) menus#new
edit_restaurant_menu_path GET (/:locale)/restaurants/:restaurant_id/menus/:id/edit(.:format) menus#edit
restaurant_menu_path GET (/:locale)/restaurants/:restaurant_id/menus/:id(.:format) menus#show
PATCH (/:locale)/restaurants/:restaurant_id/menus/:id(.:format) menus#update
PUT (/:locale)/restaurants/:restaurant_id/menus/:id(.:format) menus#update
DELETE (/:locale)/restaurants/:restaurant_id/menus/:id(.:format) menus#destroy
有趣的是,menu_spec.rb中的此测试正在运行..
interestingly is, that this test in menu_spec.rb is working..
require 'spec_helper'
describe 'Menu' do
before :each do
@restaurant = FactoryGirl.create(:random_restaurant)
@menu = FactoryGirl.create(:menu)
end
describe 'GET /menus' do
it 'responds with 200' do
get restaurant_menu_path(@restaurant, @menu)
expect(response).to be_success
expect(response.status).to eq(200)
end
end
describe 'GET all restaurants menus' do
it 'responds with 200' do
get restaurant_menus_path(@restaurant)
expect(response).to be_success
expect(response.status).to eq(200)
end
end
end
我真的不知道为什么这个测试不起作用..:(
i really dont know why this test is not working.. :(
请..我需要一些解释..如果有人可以帮助..请:) 也欢迎阅读资源:)
please.. i need some explanation.. if anyone can help.. please :) resources to read are also welcome :)
非常感谢你.
推荐答案
好的,我明白了,测试应该像这样:
ok, i got it, the tests should look like this:
it 'renders the index template' do
get :index, { :restaurant_id => @restaurant }
expect(response).to render_template('index')
end
我必须添加:restaurant_id ..然后它起作用了.
i had to add :restaurant_id.. then it worked.
