未定義的方法「補丁」 <Rspec的核心:: - Rails的教程第9章

Question

我收到以下錯誤，並不能找出如何解決它。有堆棧溢出解決類似問題的其他一些網頁，但這些似乎並不適用，或者至少我沒有足夠的悟性去解決它。

當我運行authentication_pages_spec，這個問題似乎是與使用的「補丁」，導致下面的故障。請注意，我已經嘗試用「put」替換「patch」並獲得相同的結果。

注：根據討論Stack Overflow here和blog it references here我當選爲改變我的規格/請求文件夾的投機/功能，因爲這似乎是什麼水豚2.0版本之後需要。

這是我的Gemfile： 源 'https://rubygems.org' 紅寶石 '2.0.0' ＃紅寶石寶石= railstutorial_rails_4_0

我修改Guardfile使用規格/功能文件夾，而不是規範的/請求文件夾：

require 'active_support/inflector' 

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, 
       :rspec_env => { 'RAILS_ENV' => 'test' } do 

    watch('config/application.rb') 
    watch('config/environment.rb') 
    watch('config/environments/test.rb') 
    watch(%r{^config/initializers/.+\.rb$}) 
    watch('Gemfile') 
    watch('Gemfile.lock') 
    watch('spec/spec_helper.rb') { :rspec } 
    watch('test/test_helper.rb') { :test_unit } 
    watch(%r{features/support/}) { :cucumber } 
end 

guard 'rspec', all_after_pass: false, cli: '--drb' do 
    watch(%r{^spec/.+_spec\.rb$}) 
    watch(%r{^lib/(.+)\.rb$})  { |m| "spec/lib/#{m[1]}_spec.rb" } 
    watch('spec/spec_helper.rb') { "spec" } 

    # Rails example 
    watch(%r{^app/(.+)\.rb$})       { |m| "spec/#{m[1]}_spec.rb" } 
    watch(%r{^app/(.*)(\.erb|\.haml)$})     { |m| "spec/#{m[1]}#{m[2]}_spec.rb" } 
    watch(%r{^app/controllers/(.+)_(controller)\.rb$}) { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] } 
    watch(%r{^spec/support/(.+)\.rb$})     { "spec" } 
    watch('config/routes.rb')       { "spec/routing" } 
    watch('app/controllers/application_controller.rb') { "spec/controllers" } 

    # Capybara features specs 
    watch(%r{^app/views/(.+)/.*\.(erb|haml)$})   { |m| "spec/features/#{m[1]}_spec.rb" } 

    # Turnip features and steps 
    watch(%r{^spec/acceptance/(.+)\.feature$}) 
    watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' } 

    # Custom Rails Tutorial specs 
    watch(%r{^app/controllers/(.+)_(controller)\.rb$}) do |m| 
    ["spec/routing/#{m[1]}_routing_spec.rb", 
    "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", 
    "spec/acceptance/#{m[1]}_spec.rb", 
    (m[1][/_pages/] ? "spec/features/#{m[1]}_spec.rb" : 
         "spec/features/#{m[1].singularize}_pages_spec.rb")] 
    end 
    watch(%r{^app/controllers/sessions_controller\.rb$}) do |m| 
    "spec/features/authentication_pages_spec.rb" 
    end 
end 

用戶控制器在這裏：

class UsersController < ApplicationController 
    attr_accessor :name, :email 
    before_action :signed_in_user, only: [:edit, :update] 

    def show 
    @user = User.find(params[:id]) 
    end 

    def new 
    @user = User.new 
    end 

    def create 
    @user = User.new(user_params) 
    if @user.save 
     sign_in @user 
     flash[:success] = "Welcome to the Sample App!" 
     redirect_to @user 
    else 
     flash[:error] = "Oops!" 
     render 'new' 
    end 
    end 

    def edit 
    @user = User.find(params[:id]) 
    end 

    def update 
    @user = User.find(params[:id]) 
    if @user.update_attributes(user_params) 
     flash[:success] = "Profile updated" 
     sign_in @user 
     redirect_to @user 
    else 
     render 'edit' 
    end 
    end 

    private 

    def user_params 
     params.require(:user).permit(:name, 
         :email, :password, :password_confirmation) 
    end 

    # Before filters 

    def signed_in_user 
     redirect_to signin_url, notice: "Please sign in." unless signed_in? 
    end 
end 

規格的輔助文件的位置：

require 'rubygems' 
require 'spork' 
#uncomment the following line to use spork with the debugger 
#require 'spork/ext/ruby-debug' 


Spork.prefork do 
    ENV["RAILS_ENV"] ||= 'test' 
    require File.expand_path("../../config/environment", __FILE__) 
    require 'rspec/rails' 
    require 'rspec/autorun' 

    Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } 
    ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration) 

    RSpec.configure do |config| 

    config.fixture_path = "#{::Rails.root}/spec/fixtures" 

    config.use_transactional_fixtures = true 

    config.infer_base_class_for_anonymous_controllers = false 

    config.order = "random" 

    config.include Capybara::DSL 

    # Added below myself, troubleshooting an 'undefined method 'patch'' message 
    config.include Rails.application.routes.url_helpers 
    end 
end 

Spork.each_run do 
    # This code will be run each time you run your specs. 

end 

最後，好措施，在配置/ routes.rb中的文件是在這裏：

SampleApp::Application.routes.draw do 
    resources :users 
    resources :sessions, only: [:new, :create, :destroy] 

    root 'static_pages#home' 

    match '/signup', to: 'users#new',    via: 'get' 
    match '/signin', to: 'sessions#new',   via: 'get' 
    match '/signout', to: 'sessions#destroy',  via: 'delete' 
    match '/help',  to: 'static_pages#help',  via: 'get' 
    match '/about',  to: 'static_pages#about', via: 'get' 
    match '/contact', to: 'static_pages#contact', via: 'get' 

有堆棧溢出here類似的討論，但在該職位的答案是，從移動到./spec/requests的./spec/features測試 - 我已經完成了。

另一個相關的討論here，當是在特徵文件的頂部...我已經使用require 'spec_helper'。

最後一個觀察：就這個主題的討論似乎很多表明問題是水豚需要位於spec/features文件夾中的測試才能訪問URL助手 - 但我的authentication_pages_spec.rb文件似乎對'訪問'沒有任何問題。

欣賞任何見解！ Rails 4.0的Rails教程處於測試階段，一直在試圖弄清楚這是否是一個錯誤。

* UPDATE *

得到的一切傳遞綠色執行彼得的建議後。以下是從authentication_pages_spec文件（部分，只是「授權」部分）的修改後的代碼：

describe "authorization", type: :request do 

    . 
    . 
    . 

    describe "as wrong user" do 
     let(:user) { FactoryGirl.create(:user) } 
     let(:wrong_user) {FactoryGirl.create(:user, email: "wrong@example.com") } 
     before { sign_in user, no_capybara: true } 

     describe "visiting Users#edit page" do 
     before { visit edit_user_path(wrong_user) } 
     it { should_not have_title(full_title('Edit user')) } 
     end 

     describe "submitting a PATCH request to the Users#update action" do 
     before { patch user_path(wrong_user) } 
     # NOTE: Rails Tutorial uses root_url below not root_path 
     specify { expect(response).to redirect_to(root_path) } 
     end 
    end 
    end 
end 

Answer 1

get，put，patch等僅用於:controller和:request規格定義，而不是一個:feature屬，當你改變它的位置時，你的authentication_pages_spec.rb測試隱含地變成了。如果在頂級describe中包含type: :request，它應該可以工作。

Answer 2

這個問題的答案也修復了這個RSpec的測試沒有錯誤失敗這是Rails教程第9章（規格/請求/ authentication_pages_spec.rb）

describe "submitting to the update action" do 

     before { patch user_path(user) } 

     specify { response.should redirect_to(signin_path) } 

    end
