Rails 异常：没有路线匹配 [GET] "/clock_events/1/clock_in"答案

【问题标题】：Rails exception: No route matches [GET] "/clock_events/1/clock_in"Rails 异常：没有路线匹配 [GET] "/clock_events/1/clock_in"

【问题描述】：

它曾经可以工作，但经过一些更改后，Action Controller 捕获异常
Routing Error: No route matches [GET] "/clock_events/1/clock_in"

routes.rb文件：

Rails.application.routes.draw do
  root to: 'clock_events#index'

  get '/register', to: 'users#new'
  get '/login', to: 'sessions#new'
  post '/login', to: 'sessions#create'
  get '/logout', to: 'sessions#destroy'

  resources :clock_events, except: [:destroy] do
    member do
      post 'clock_in', to: 'clocks#clock_in'
      post 'clock_out', to: 'clocks#clock_out'
    end
  end

  resources :users, except: [:destroy]

end

【解决方案1】：

您已经使用post http 动词定义了clock_in，这里：

resources :clock_events, except: [:destroy] do
  member do
    post 'clock_in', to: 'clocks#clock_in'
    post 'clock_out', to: 'clocks#clock_out'
  end
end

但是，您正在尝试使用 get 动词，如下所示：

Routing Error: No route matches [GET] "/clock_events/1/clock_in"

您需要更改路径以使用 get 动词：

resources :clock_events, except: [:destroy] do
  member do
    get 'clock_in', to: 'clocks#clock_in'
    post 'clock_out', to: 'clocks#clock_out'
  end
end

或者修改您的链接（或其他）以使用post 方法。

此外，您的 clock_in 和 clock_out 操作在 clocks 控制器上调用，而不是在 clock_events 控制器上调用，如您的 to: 指令所示：

resources :clock_events, except: [:destroy] do
  member do
    post 'clock_in', to: 'clocks#clock_in'
    post 'clock_out', to: 'clocks#clock_out'
  end
end

您确定不想使用ClockEventsController 吗？如果是这样，你可以这样做：

resources :clock_events, except: [:destroy] do
  member do
    post :clock_in
    post :clock_out
  end
end

在这种情况下你会得到：

 clock_in_clock_event POST   /clock_events/:id/clock_in(.:format)      clock_events#clock_in
clock_out_clock_event POST   /clock_events/:id/clock_out(.:format)     clock_events#clock_out
         clock_events GET    /clock_events(.:format)                   clock_events#index
                      POST   /clock_events(.:format)                   clock_events#create
      new_clock_event GET    /clock_events/new(.:format)               clock_events#new
     edit_clock_event GET    /clock_events/:id/edit(.:format)          clock_events#edit
          clock_event GET    /clock_events/:id(.:format)               clock_events#show
                      PATCH  /clock_events/:id(.:format)               clock_events#update
                      PUT    /clock_events/:id(.:format)               clock_events#update
