Question

我有一个控制器，其中包含许多操作：

class TestsController < ApplicationController
   def find
   end

   def break
   end

   def turn
   end
end

当我将其添加到我的routes.rb文件时，如下所示：

resources :tests

并执行rake routes任务我看到以下额外轮次：

    tests GET    /tests(.:format)          tests#index
          POST   /tests(.:format)          tests#create
 new_test GET    /tests/new(.:format)      tests#new
edit_test GET    /tests/:id/edit(.:format) tests#edit
     test GET    /tests/:id(.:format)      tests#show
          PUT    /tests/:id(.:format)      tests#update
          DELETE /tests/:id(.:format)      tests#destroy

显然我的控制器没有上述动作。那么如何告诉Rails避免生成/期望这些路由？

Answer 1

只需为没有CRUD的未来简单路线添加答案：

resources :tests, only: [] do 
  collection do 
    get 'find'
    match 'break'
    match 'turn'
  end 
end

# output of rake routes

find_tests GET /tests/find(.:format)  tests#find
break_tests     /tests/break(.:format) tests#break
turn_tests     /tests/turn(.:format)  tests#turn

或使用namespace代替resources

namespace :tests do
  get 'find'
  match 'break'
  match 'turn'
end

# output of rake routes

tests_find GET /tests/find(.:format)  tests#find
tests_break     /tests/break(.:format) tests#break
tests_turn     /tests/turn(.:format)  tests#turn

for Rails 4.（导致{4. 3}在rails 4.x或最新版本中）

resources :tests, only: [] do 
  collection do 
    get 'find'
    get 'break'
    get 'turn'
  end 
end

使用namespace

namespace :tests do
  get 'find'
  get 'break'
  get 'turn'
end

Answer 2

您可以像这样指定要路由的操作：

resources :tests, except: [:new, :create, :edit, :update, :destroy] do 
  collection do 
    get 'find'
    get 'break'
    get 'turn'
  end 
end

Answer 3

如果您不想使用其他路线，请不要使用resources，请指定每条路径和操作。

get '/tests/find' => 'tests#find'
post '/tests/break' => 'tests#break'
post '/tests/turn' => 'tests#turn'

你指定params如下：

post '/tests/add/:id' => 'tests#add'
