新控制器 - 沒有路線匹配更新，編輯，顯示或銷燬

Question

我有一些困難讓所有的RESTful路線設置正確。到目前爲止，我已經在我的應用程序中採用了最簡單的步驟。

1. 創建新的Rails應用
2. 創建REST風格的動作新控制器
3. 添加resources到routes.rb

然而4了我7個的行動失敗的默認測試。任何人都可以解釋爲什麼？

rails generate controller Employees new create update edit destroy index show 

下面是相應的控制器，employees_controller.rb

class EmployeesController < ApplicationController 
    def new 
    end 

    def create 
    end 

    def update 
    end 

    def edit 
    end 

    def destroy 
    end 

    def index 
    end 

    def show 
    end 
end 

現在我的資源添加到routes.rb

Rails.application.routes.draw do 

    resources :employees 

end 

所有路由都似乎是有根據的rake routes

輸出

 Prefix Verb URI Pattern     Controller#Action 
    employees GET /employees(.:format)   employees#index 
       POST /employees(.:format)   employees#create 
new_employee GET /employees/new(.:format)  employees#new 
edit_employee GET /employees/:id/edit(.:format) employees#edit 
    employee GET /employees/:id(.:format)  employees#show 
       PATCH /employees/:id(.:format)  employees#update 
       PUT /employees/:id(.:format)  employees#update 
       DELETE /employees/:id(.:format)  employees#destroy 

但現在當我運行默認的測試中，我得到的4個錯誤：

# Running: 

.EEEE.. 

Finished in 0.267712s, 26.1475 runs/s, 11.2061 assertions/s.

7 runs, 3 assertions, 0 failures, 4 errors, 0 skips 

最後，這裏是employees_controller_test.rb內容。正如我所說的，這些是Rails在生成控制器時自動創建的默認測試。

require 'test_helper' 

class EmployeesControllerTest < ActionController::TestCase 
    test "should get new" do 
    get :new 
    assert_response :success 
    end 

    test "should get create" do 
    get :create 
    assert_response :success 
    end 

    test "should get update" do 
    get :update 
    assert_response :success 
    end 

    test "should get edit" do 
    get :edit 
    assert_response :success 
    end 

    test "should get destroy" do 
    get :destroy 
    assert_response :success 
    end 

    test "should get index" do 
    get :index 
    assert_response :success 
    end 

    test "should get show" do 
    get :show 
    assert_response :success 
    end 

end 

Answer 1

根據dimakura的回答，你必須改變一些線路在您的測試

的更新方法是put（或在rails4局部變化的patch）

test "should get update" do 
    put :update 
    assert_response :success 
    end 

，併爲您的編輯，刪除並顯示路由，id缺失

test "should get edit" do 
    get :edit, id: 2 
    assert_response :success 
    end 

Answer 2

你的控制器測試大概是這樣的：

class EmployeesControllerTest < ActionController::TestCase 
    test "should get create" do 
    get :create 
    assert_response :success 
    end 

    # other tests not shown 

末

你應該把它改成這樣：

class EmployeesControllerTest < ActionController::TestCase 
    test "should get create" do 
    post :create 
    assert_response :success 
    end 

    # other tests should be changed accordingly 
end 

使用patch或updateput方法，並delete爲delete行動。
