Question

我想添加一项功能，通过单击一个按钮返回属于一个导演的所有电影信息。它已经实现并且运行良好，但在编写Rspec测试时出现了一些错误。错误消息是：

(1)MoviesController searching for movies by the same director when 'Director' info exists should post @director and @movies variables for view
 Failure/Error: get :find_movies_by_same_director, :movie_id => @movie.id, :movie_director => @movie.director

 ActionController::RoutingError:
   No route matches {:movie_id=>"1", :movie_director=>["Star Wars", "THX-1138"], :controller=>"movies", :action=>"find_movies_by_same_director"}

 # ./spec/controllers/movie_controller_spec.rb:15:in `block (4 levels) in <top (required)>'

以下测试中发现没有找到路由的类似错误，所以我认为我的路由文件可能存在一些问题。这是我在routes.rb中指定的路径：

   get '/movies/:id/director', to: 'movies#find_movies_by_same_director', as: 'director'

Rspec文件是：

require "spec_helper"

describe MoviesController do
it { should respond_to(:find_movies_by_same_director) }

describe "searching for movies by the same director" do
  context "when 'Director' info exists" do
    before do
      @movie = double(:title => "Star Wars", :id => "1", :director => "George Lucas")
      Movie.stub(:find).with("1").and_return @movie
      @lucas_films = ["Star Wars", "THX-1138"]
      @movie.stub(:director).and_return @lucas_films
    end
    it "should post @director and @movies variables for view" do
      get :find_movies_by_same_director, :movie_id => @movie.id
      assigns(:director).should == @movie.director
      assigns(:movies).should == @lucas_films
    end
  end
end

控制器方法是：

def find_movies_by_same_director
  @movie = Movie.find(params[:id])
  @director = @movie.director
  if (not @director.nil?) and (not @director.empty?)
    @movies = Movie.where(director: @director) if (not @director.nil?) and (not @director.empty?);
    #@movies = Movie.find_by_sql("SELECT * FROM movies i WHERE i.director == '#{@director}'")
  render :director 
  else
    flash[:notice] = "'#{@movie.title}' has no director info"
    redirect_to root_path
end

我刚刚开始学习Rspec，所以任何评论或建议都会受到赞赏。

从路径中可以看出，您的操作需要参数:id。您正在通过:movie_id。所以，只需在规范中替换此行

 get :find_movies_by_same_director, :movie_id => @movie.id

与

 get :find_movies_by_same_director, :id => @movie.id

再试一次。

Rspec没有路由匹配错误
