如何在嵌套资源上设置Rails路由?

这可能看似多余,因为类似的问题已经被问到herehere,但我还没有找到解决方案。

我正在运行RSpec来测试:更新api。当我运行RSpec时,它在我的第一次测试时显示No Route Matches。我需要的是对未经身份验证的用户进行have_http_status(401)测试。 Rails无法弄清楚路由。 这是错误所说的:

Failures:

  1) PostsController unauthenticated user PUT update returns http unauthenticated
     Failure/Error: put :update, topic_id: my_topic.id, post_id: my_post.id, post: {title: my_post.title, body: my_post.body}

     ActionController::UrlGenerationError:
       No route matches {:action=>"update", :controller=>"posts", :post=>{:title=>"Xdiwbu zuitsom prubmlhd oxmgtkb swphb ukije salhvk.", :body=>"Pjlb ywlzqv igdesqmw oqjgy mrwpye ujierxtn owqxbvt. Wzxu sjcikthg xare tcawzx tedmiqwf lewab. Twkeoun mos ophta fvae krmnsqe. Jxefyo ncd agj ieyanvt uehazwnk mtsi fbsm."}, :post_id=>"1", :topic_id=>"1"}
     # ./spec/api/v1/controllers/posts_controller_spec.rb:11:in `block (3 levels) in <top (required)>'

这是RSpec(spec / api / v1 / controllers / posts_controller_spec.rb)

require 'rails_helper'

RSpec.describe Api::PostsController, type: :controller do
  let(:my_user) { create(:user) }
  let(:my_topic) { create(:topic) }
  let(:my_post) { create(:post, topic: my_topic, user: my_user) }

context "unauthenticated user" do

it "PUT update returns http unauthenticated" do
  put :update, topic_id: my_topic.id, post_id: my_post.id, post: {title: my_post.title, body: my_post.body}
  expect(response).to have_http_status(401)
end
...

以下是路线:

  namespace :api do
    namespace :v1 do
      resources :users, only: [:index, :show, :create, :update]
      resources :topics, except: [:edit, :new] do
        resources :posts, only: [:update, :create, :destroy]
      end
    end
  end

以下是测试的第一部分:

class Api::V1::PostsController < Api::V1::BaseController
  before_action :authenticate_user, except: [:index, :show]
  before_action :authorize_user, except: [:index, :show]

     def update
       post = Post.find(params[:id])

       if post.update_attributes(post_params)
         render json: post.to_json, status: 200
       else
         render json: {error: "Post update failed", status: 400}, status: 400
       end
     end
...

无论我改变RSpec,我都无法让它与路线相匹配。你们介意帮忙吗?

谢谢!

答案 0 :(得分:3)

有两件事让我感到高兴。

1:控制器本身在Api::V1下被命名空间。但是,规范中的控制器仅在Api下被命名空间。这应该更新以匹配。

2:如果您运行rake routes,您会注意到这样的一行:

PUT /api/v1/topics/:topic_id/posts/:id(.:format) api/v1/posts#update

注意在该消息中:之后给出的名称非常重要。在这里,它说明主题的ID应该作为topic_id提供给控制器,并且帖子的ID应该只提供id。如果您将put语句修改为更像put :update, topic_id: my_topic.id, id: my_post.id, post: {title: my_post.title, body: my_post.body}的内容,则应该有效。
