Question

我目前停留在Michael Hartl（railstutorial.org）第13章

的导轨教程中

并收到以下两个错误：

1) Error:
MicropostsControllerTest#test_should_redirect_create_when_not_logged_in:
ActionController::UrlGenerationError: No route matches {:action=>"/microposts", :controller=>"microposts", :params=>{:micropost=>{:content=>"Lorem ipsum"}}}
    test/controllers/microposts_controller_test.rb:11:in 'block (2 levels) in <class:MicropostsControllerTest>'
    test/controllers/microposts_controller_test.rb:10:in 'block in <class:MicropostsControllerTest>'


  2) Error:
MicropostsControllerTest#test_should_redirect_destroy_when_not_logged_in:
ActionController::UrlGenerationError: No route matches {:action=>"/microposts/499495288", :controller=>"microposts"}
    test/controllers/microposts_controller_test.rb:18:in 'block (2 levels) in <class:MicropostsControllerTest>'
    test/controllers/microposts_controller_test.rb:17:in 'block in <class:MicropostsControllerTest>'

据我所知，＆＃39;行动＆＃39;应该像get，post，delete等。但是我不知道，为什么它会说＆＃39; micropost＆＃39;这里。

microposts_controller_test.rb的内容：

require 'test_helper'

class MicropostsControllerTest < ActionController::TestCase

  def setup
    @micropost = microposts(:orange)
  end

  test 'should redirect create when not logged in' do
    assert_no_difference 'Micropost.count' do
      post microposts_path, params: {micropost: {content: 'Lorem ipsum'}}
    end
    assert_redirected_to login_url
  end

  test 'should redirect destroy when not logged in' do
    assert_no_difference 'Micropost.count' do
      delete micropost_path(@micropost)
    end
    assert_redirected_to login_url
  end
end

micropost_controller.rb的内容：

class MicropostsController < ApplicationController
  before_action :logged_in_user, only: [:create, :destroy]

  def create
    @micropost = current_user.microposts.build(micropost_params)
    if @micropost.save
      flash[:success] = 'Micropost created!'
      redirect_to root_url
    else
      render 'static_pages/home'
    end
  end

  def destroy
  end

  private

  def micropost_params
    params.require(:micropost).permit(:content)
  end

end

routes.rb的内容：

Rails.application.routes.draw do
  root 'static_pages#home'
  get '/help' => 'static_pages#help'
  get '/about' => 'static_pages#about'
  get '/contact' => 'static_pages#contact'
  get '/signup' => 'users#new'
  get '/login' => 'sessions#new'
  post '/login' => 'sessions#create'
  delete '/logout' => 'sessions#destroy'
  resources :users
  resources :account_activations, only: [:edit]
  resources :password_resets, only:     [:new, :create, :edit, :update]
  resources :microposts, only:           [:create, :destroy]
end

感谢任何帮助。

编辑：

在micropost_controller_test.rb中，它应该是：

class MicropostsControllerTest < ActionDispatch::IntegrationTest

而不是

class MicropostControllerTest < ActionCntroller::TestCase

Answer 1

第一个测试的问题是你在控制器/微博中没有路线＆＃34;测试试图点击，如果你看到你的路线文件，它确认resources :microposts, only: [:create, :destroy]，所以没有路由。其次，在销毁之后它应该重定向，并且在你的控制器方法中没有重定向。所以最终测试失败了。

Answer 2

在micropost_controller_test.rb中，它应该是：

class MicropostsControllerTest < ActionDispatch::IntegrationTest

而不是

class MicropostControllerTest < ActionCntroller::TestCase

没有路线匹配{：action =＆gt;＆＃34; / microposts＆＃34;，：controller =＆gt;＆＃34; microposts＆＃34;，：params =＆gt; {：micropost =＆gt; {：content =＆gt; ＆＃34; Lorem ipsum＆＃34;}}}
