如何正确定义Rails路由,以便资源的某些操作转到一个控制器而另一些转到另一个控制器？

Question

我的应用程序有products,categories和subcategries.我在网址/dash上有一个管理界面来编辑这些详细信息.我试着像这样设置网址:

• 产品在网址下创建,更新,销毁和索引 /dash/products
• 产品展示如下 /products/porduct-code
• 类别显示在 /category-name
• /dash/editcategories指向动作的类别编辑列表editcategories
• 子类别显示在 category-name/subcategory-name
• 编辑也属于上面的类别
• 类别和子类别创建,更新,删除和索引全部 /dash

当我试图解决一件事时,另一件事打破了.我的整个路线文件变得一团糟.试图解决它们,事情不会奏效.这是我的路线文件:

Rails.application.routes.draw do

    # Pages
    root 'pages#home'
    get 'terms' => 'pages#termsandconditions'
    get 'delivery-charges' => 'pages#deliverycharges'
    get 'search' => 'pages#search'
    get 'deals' => 'pages#alldeals'
    get 'contact', to: 'pages#contact'
    post 'contact', to: 'pages#contactscreate'
    get 'dealslist' => 'pages#dealslist'

    get 'cart' => 'carts#cart'

    get 'rate' => 'districtrates#rate'
    get 'deliverycharges' => 'districtrates#deliverycharges'
    get 'pricecalc' => 'pages#pricecalc'

    # Devise routes

    # Others
    resources :users
    resources :brands
    resources :orders

    get 'dash/subcategorylist' => 'products#subcategorylist'
    get 'dash'  =>  'dash#index'

    get '/products/:id', to: 'pages#product'

    scope '/dash' do
        resources :districtrates, as: 'deliveryrates'
        resources :slides
        resources :images
        resources :colorqtys
        resources :products
        get 'imagelist' => 'images#imagelist'
        get 'slidelist' => 'slides#slidelist'
        get 'update_deliveryrates' => 'districtrates#update_deliveryrates'
        get 'adminlogs' => 'logs#adminlogs'
    end

    get '/:id', to: 'categories#show'

    scope '/dash' do
        get 'editcategories' => 'categories#edit_categories'
    end

    scope '/:id' do
        get '/:id', to: 'subcategories#show'
    end

    resources :categories, path: '/dash/category' do
        get 'editsubcategories' => 'subcategories#edit_subcategories'
    end

    get 'dash/category/new' => 'categories#new'
    post 'dash/categories' => 'categories#create'
    delete 'dash/category/:id' => 'categories#destroy'
    patch 'dash/category/:id' => 'categories#update'

    get 'dash/subcategory/new' => 'subcategories#new'
    post 'dash/subcategories' => 'subcategories#create'
    delete 'dash/subcategory/:id' => 'subcategories#destroy'
    patch 'dash/subcategory/:id' => 'subcategories#update'

    get 'dash/colors' => 'colors#index'

    post 'dash/saveimages' => 'images#saveimages'
    post 'dash/savecolorqtys' => 'colorqtys#savecolorqtys'
end

请帮我修复冲突问题并清理我的路线文件.另外,请给我一个很好的指南,了解Rails路线.

Answer 1

RESTüberallles:

您可以通过坚持使用rails REST惯例来清理路径文件中的大部分内容.这还应该提高应用程序的一致性.我相信在很多情况下,您只是为了获取简短的网址而损害您的应用程序的设计.

使许多航线在'/'"命名",如'/about','/faq'等的小型网站工作正常,或者如果你正在建立一个应用程序,它主要使用单一类型的资源(如应用程序的Todo)交易.但是当你拥有许多类型的资源和公平的复杂性时,它会导致设计非常薄弱.

将每个资源放入自己的小框(/users,/pets)中可以创建漂亮的RESTful接口,并降低复杂性以及路由模糊和冲突的风险.

在命名资源时,您还应该使用snake_case来提高可读性:

resources :districtrates # bad
resources :district_rates # better

让我们重构并弄脏重构:

get 'contact', to: 'pages#contact'
post 'contact', to: 'pages#contactscreate'

在PagesController中挂载一些"静态"路由并"手动"创建路径就可以了.但这真的很有气味,因为合同实际上是可以更加安静地建模的东西.

创建一个ContactsController并将路径定义更改为:

resources :contacts, only: [:new, :create]
# GET /contacts/new
# POST /contacts

如果你绝对必须有一条/contact路径:

get 'contact', to: 'contacts#new'
# But don't create that POST route! 

其他相同治疗的候选人是dealslist,deliverycharges.

管理界面:

我认为你应该完全接受"在页面编辑上"(使用标准控制器,路由和视图)或者拥有一个带有自己的控制器和视图的管理命名空间.

因此,您将更改路由定义以使用Dash命名空间.

namespace :dash
  resources :slides
  resources :images
  resources :products
  # ...

  get 'imagelist' => 'images#imagelist' # BAD. Use images#index instead
  get 'slidelist' => 'slides#slidelist' # BAD. Use slides#index instead
end

这将路由到Dash::ImagesController.使用关注点(mixins)作为交叉重复的方法.

可以使用嵌套来路由类别和子类别.

namespace :dash
  resources :categories do
    resources :categories, as: 'sub_categories', controller: 'dash/categories'
  end
end

加成:

公共类别:

resources :categories, only: [:show] do
  resources :categories, 
            as: 'sub_categories', 
            controller: 'categories',
            only: [:show]
end
