路由到控制器

Question

的行動上，我用：

指在類別中的動作指數controller.All工作得很好！

現在，我創建了類控制器的新動作

def search 
@categories = Category.order(:name).where("name like ?", "%#{params[:term]}%") 

render json: @categories.map(&:name) 
end 

並試圖指向行動：

data: {autocomplete_source: search_categories_path} %> 

，但我得到的錯誤：

undefined local variable or method `search_categories_path' for #<#<Class:0x51844c8>:0x5375820> 

什麼了我錯了？謝謝！

我的路線：

 products GET /products(.:format)   products#index 
      POST /products(.:format)   products#create 
new_product GET /products/new(.:format)  products#new 
edit_product GET /products/:id/edit(.:format) products#edit 
    product GET /products/:id(.:format)  products#show 
      PUT /products/:id(.:format)  products#update 
      DELETE /products/:id(.:format)  products#destroy 
categories GET /categories(.:format)   categories#index 
      POST /categories(.:format)   categories#create 
new_category GET /categories/new(.:format)  categories#new 
edit_category GET /categories/:id/edit(.:format) categories#edit 
category GET /categories/:id(.:format)  categories#show 
      PUT /categories/:id(.:format)  categories#update 
      DELETE /categories/:id(.:format)  categories#destroy 

路線：

Autorails::Application.routes.draw do 
resources :products 


resources :categories do 
collection do 
    :search 
end 
end 

Answer 1

你應該有這樣的事情在你的routes.rb：

resources :categories do 
    collection do 
    get :search 
    end 
end 

Answer 2

檢查rake routes如果該路由下該名稱確實存在。 欲瞭解更多信息，請參閱http://guides.rubyonrails.org/routing.html#path-and-url-helpers

Answer 3

你應該做這樣的事情

resources :categories do 
    collection do 
    get :search 
    end 
end
