没有路线匹配{：action =＆gt;“up_vote”，：controller =＆gt;“votes”，：post_id =＆gt;“1”}

Question

我试图让我的upvote方法通过时，我的RSpec中一直收到以下错误：

Failures:
1) VotesController#up_vote adds an up-vote to the post
 Failure/Error: post( :up_vote, post_id: @post.id )
 ActionController::UrlGenerationError:
   No route matches {:action=>"up_vote", :controller=>"votes", :post_id=>"1"}

现在，当我在服务器上时，我可以进行upvote和downvote，这只是我的测试不起作用。

这是我的代码：

votes_controller_spec.rb

require 'rails_helper'

describe VotesController do

  include TestFactories
  include Devise::TestHelpers

  describe '#up_vote' do
    it "adds an up-vote to the post" do
      request.env["HTTP_REFERER"] = '/'
      @user = authenticated_user
      @post = associated_post
      sign_in @user

      expect {
        post(:up_vote, post_id: @post.id)
      }.to change { @post.up_votes }.by 1
    end
  end
end

votes_controller.rb

class VotesController < ApplicationController
  before_action :load_post_and_vote

  def up_vote
    update_vote!(1)
    redirect_to :back
  end

  def down_vote
    update_vote!(-1)
    redirect_to :back
  end

  def update_vote!(new_value)

    if @vote
      authorize @vote, :update?
      @vote.update_attribute(:value, new_value)
    else
      @vote = current_user.votes.build(value: new_value, post: @post)
      authorize @vote, :create?
      @vote.save
    end
  end

  private

  def load_post_and_vote
    @post = Post.find(params[:post_id])

    @vote = @post.votes.where(user_id: current_user.id).first
  end
end

的routes.rb

Rails.application.routes.draw do

  devise_for :users
  resources :users, only: [:update]
  resources :questions
  resources :advertisements

  resources :topics do
    resources :posts, except: [:index] do
      resources :summaries, only: [:create, :new, :show]
      resources :comments, only: [:create, :destroy]

      post '/up-vote', to: 'votes#up_vote', as: :up_vote
      post '/down-vote', to: 'votes#down_vote', as: :down_vote
    end
  end

  get 'about' => 'welcome#about'
  get 'contact' => 'welcome#contact'

  root to: 'welcome#index'

end

模块提供规范中的方法：

module TestFactories
  def associated_post(options={})
    post_options = {
        title: 'Post title',
        body: 'Post bodies must be pretty long.',
        topic: Topic.create(name: 'Topic name'),
        user: authenticated_user
    }.merge(options)

    Post.create(post_options)
  end

  def authenticated_user(options={})
    user_options = {email: "email#{rand}@fake.com", password: 'password'}.merge(options)
    user = User.new(user_options)
    user.skip_confirmation!
    user.save
    user
  end
end

相关的Rake路线

topic_post_up_vote POST   /topics/:topic_id/posts/:post_id/up-vote(.:format)       votes#up_vote
topic_post_down_vote POST   /topics/:topic_id/posts/:post_id/down-vote(.:format)     votes#down_vote

为什么我收到此URL生成错误的任何想法？

Answer 1

我认为您只需要将topic_id传递给post方法，如下所示：post( :up_vote, post_id: @post.id, topic_id: @post.topic.id )

Answer 2

我最终将routes.rb文件切换到下面，并使上面的vote_controller_spec.rb工作。

myobject.myset = myobject.myset.union(yourset)
