向 Rails 4 中的非休息路线添加方法

Question

我想对我的一些路由执行操作，问题是它们不在“资源”块中，因为我需要为每个路由命名方法。我希望能够在索引类型视图中切换每个项目中每个属性的状态。我正在尝试合并this 教程。

  devise_for :admins  # The priority is based upon order of creation: first created -> highest priority.
  root 'home#index'
  resources :entries, :only => [:index, :new, :create] 
  namespace :admin do 
    namespace :entries do
      match :pending, :via => [:get, :post], :collection => { :toggle_approve => :put}
      match :rejected, :via => [:get, :post], :collection => { :toggle_approve => :put}
      match :approved, :via => [:get, :post], :collection => { :toggle_approve => :put}
    end
  end

进入控制器

class Admin::EntriesController < ApplicationController

  expose(:entries){@entries}


  def index
  end

  def show
  end

  def approved 
    @entries = Photo.with_approved_state
  end

  def pending
    @entries = Photo.with_pending_state 
  end

  def rejected
    @entries = Photo.with_rejected_state
  end

  def toggle_approve  
    @a = Photo.find(params[:id])  
    @a.toggle!(:workflow_state)  
    render :nothing => true  
  end

Answer 1

我不知道collection 选项的来源（我在任何地方都找不到对它的引用）

实现非资源路由其实比较简单：

#config/routes.rb
resources :entries, only: [:index, :new, :create] do
    collection do
       match :pending, via: [:get, :post]  #-> domain.com/entries/pending
       match :rejected, via: [:get, :post] #-> domain.com/entries/rejected
       match :approved, via: [:get, :post] #-> domain.com/entries/approved
    end
end

我不理解 collection 选项 - 我认为这不属于您的路线。虽然已经考虑过了，但我想您正在尝试这样做，以便如果您收到对 domain.com/entries/toggle_approve_article/pending 的请求，您会想要处理请求？

如果是这样，为什么不这样做：

#config/routes.rb
resources :entries, only: [:index, :new, :create] do
    put :toggle_approve #-> domain.com/entries/15/toggle_approve
    collection do
       match :pending, via: [:get, :post]  #-> domain.com/entries/pending
       match :rejected, via: [:get, :post] #-> domain.com/entries/rejected
       match :approved, via: [:get, :post] #-> domain.com/entries/approved
    end
end

Answer 2

我必须了解成员和集合之间的区别。集合是附加到资源的路由（例如，restful 操作）。成员是可以在其块上执行操作的额外路由。

这...

resources :entries, :only => [:index, :new, :create]
  namespace :admin do
    resources :entries do
      get :pending, on: :collection
      get :approved, on: :collection
      get :rejected, on: :collection
      member do 
        get :toggle_approve_field
        get :toggle_reject_field
      end
    end 
  end

产生了这条 rake 路线

entries GET    /entries(.:format)                                entries#index
                                 POST   /entries(.:format)                                entries#create
                       new_entry GET    /entries/new(.:format)                            entries#new
           pending_admin_entries GET    /admin/entries/pending(.:format)                  admin/entries#pending
          approved_admin_entries GET    /admin/entries/approved(.:format)                 admin/entries#approved
          rejected_admin_entries GET    /admin/entries/rejected(.:format)                 admin/entries#rejected
toggle_approve_field_admin_entry GET    /admin/entries/:id/toggle_approve_field(.:format) admin/entries#toggle_approve_field
 toggle_reject_field_admin_entry GET    /admin/entries/:id/toggle_reject_field(.:format)  admin/entries#toggle_reject_field
                   admin_entries GET    /admin/entries(.:format)                          admin/entries#index
                                 POST   /admin/entries(.:format)                          admin/entries#create
                 new_admin_entry GET    /admin/entries/new(.:format)                      admin/entries#new
                edit_admin_entry GET    /admin/entries/:id/edit(.:format)                 admin/entries#edit
                     admin_entry GET    /admin/entries/:id(.:format)                      admin/entries#show
                                 PATCH  /admin/entries/:id(.:format)                      admin/entries#update
                                 PUT    /admin/entries/:id(.:format)                      admin/entries#update
                                 DELETE /admin/entries/:id(.:format)                      admin/entries#destroy

这花了很多时间，我不确定我是否能够根据要求做到这一点而不会更加头疼，但我当然对 Rails 路由有更好的了解。感谢@RichPeck 的帮助
