Question

我有一个servicebooking模型，当我在accept_booking展示视图中点击以下链接时，我正在尝试更新其servicebooking列，其值为：

<%= link_to 'Accept this booking', acceptbooking_servicebooking_path(@servicebooking) %>

我收到以下错误：

undefined method `acceptbooking_servicebooking_path' for #<#<Class:0x5a35e98>:0x5a2bbf0>

下面我在routes.rb

中声明了路线

get 'acceptbooking', to: 'servicebookings#acceptbooking'

我的servicebookings控制器中有以下的acceptbooking方法：

def acceptbooking
    render nothing: true
    @servicebooking = Servicebooking.find(params[:id])
    @servicebooking.update_attribute(:accept_booking, 1) 
  end

我的Routes.rb

Appa::Application.routes.draw do
  devise_for :users
  devise_for :views
  get "welcome/index"
  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  root 'welcome#index'
  get 'myevents', to: 'events#myevents'
  get 'myvenues', to: 'venues#myvenues'
  get 'myservices', to: 'services#myservices'
  get 'make_available', to: 'services#make_available'
  get 'myservicebookings', to: 'servicebookings#myservicebookings'
  get 'acceptbooking', to: 'services#acceptbooking'

  #match 'acceptbooking', to: 'servicebookings#acceptbooking', via: [:get, :post]
  resources :events do
     resources :comments

   end

   resources :users do
     resources :events
   end

   resources :venues do
     resources :comments do
       collection do
         post :venuec
       end
     end
   end

   resources :services do
     resources :comments do
       collection do
         post :servicec
       end
     end
   end

   resources :servicebookings do
     resources :services
   end
end

谁能看到我在哪里出错了？谢谢你们。

Answer 1

试试这个：get 'acceptbooking/:id', to: 'servicebookings#acceptbooking', as: 'acceptbooking_servicebooking'

Answer 2

仅使用路线定义（来自路线文件）：

get 'acceptbooking', to: 'servicebookings#acceptbooking'

路线名称为acceptbooking，因此您应该使用acceptbooking_path。但根据您的<%= link_to 'Accept this booking', acceptbooking_servicebooking_path(@servicebooking) %>，您似乎想要一个类似/servicebookings/:service_booking_id/acceptbooking的网址。如果是这种情况，那么您应该将路线定义更新为：

resources :servicebookings do
  resources :services

  # Move the following line here from the top.
  get 'acceptbooking', to: 'servicebookings#acceptbooking'
end

这会给你servicebooking_acceptbooking_path（注意服务预订和接受预订的顺序）。
