Question

我正在使用Versionist对我的API进行版本控制，所以现在我的路径文件看起来像

Rails.application.routes.draw do
  api_version(:module => "V1", :path => {:value => "v1"}) do
    resources :concepts, except: [:new, :edit]
  end
end

我的控制器位于app/controllers/v1/concepts_controller.rb。

在spec/controllers/v1/concepts_controller_spec.rb里面我有

  ...

  describe "POST #create" do
    context "with valid params" do
      it "creates a new Concept" do
        expect {
          post :create, {:concept => valid_attributes}, valid_session
        }.to change(Concept, :count).by(1)
      end

      ...
    end
  end

  ...

  describe "PUT #update" do
    context "with valid params" do
      let(:new_attributes) { {description: 'Sample description.'} }

      it "updates the requested concept" do
        concept = Concept.create! valid_attributes
        put :update, {:id => concept.to_param, :concept => new_attributes}, valid_session
        concept.reload
        expect(concept.description).to eq('Sample description.')
      end

      ...

PUT #update测试工作正常，但所有POST #create测试都给了我

1) V1::ConceptsController POST #create with valid params creates a new Concept
     Failure/Error: post :create, {:concept => valid_attributes}, valid_session

我的佣金路线：

     Prefix Verb   URI Pattern                Controller#Action
v1_concepts GET    /v1/concepts(.:format)     v1/concepts#index
            POST   /v1/concepts(.:format)     v1/concepts#create
 v1_concept GET    /v1/concepts/:id(.:format) v1/concepts#show
            PATCH  /v1/concepts/:id(.:format) v1/concepts#update
            PUT    /v1/concepts/:id(.:format) v1/concepts#update
            DELETE /v1/concepts/:id(.:format) v1/concepts#destroy

如何让它使用v1_concept_url代替？为什么即使是GET请求，它甚至会调用concept_url？＆＃39;

编辑我的控制器：

class V1::ConceptsController < V1::BaseController
  before_action :set_concept, only: [:show, :update, :destroy]

  # GET /concepts
  # GET /concepts.json
  def index
    @concepts = Concept.all

    render json: @concepts
  end

  # GET /concepts/1
  # GET /concepts/1.json
  def show
    render json: @concept
  end

  # POST /concepts
  # POST /concepts.json
  def create
    @concept = Concept.new(concept_params)

    if @concept.save
      render json: @concept, status: :created, location: @concept
    else
      render json: @concept.errors, status: :unprocessable_entity
    end
  end

  ...

显然location标题是罪魁祸首。传入实例变量@concept会导致Rails调用concept_url帮助程序。

您可以通过自己调用帮助程序来覆盖它：

location: v1_concept_url(@concept)

在模块中使用Rails URL帮助程序
