Question

我正在尝试设置自定义路线。但是每当我点击beverage_locations / new页面时，它都会尝试在url中发送'new'作为索引路径中的：location_id。

route.rb

  controller 'beverage_locations' do
     get 'beverage_locations/:location_id' => 'beverage_locations#index'
     get 'beverage_locations/new' => 'beverage_locations#new'
  end

错误

ActiveRecord::RecordNotFound in BeverageLocationsController#index

Couldn't find Location with id=new

任何想法如何解决这个问题？

谢谢！

Rails路由按照指定的顺序进行匹配，所以如果你有一个资源：上面的照片得到'照片/民意调查'的节目动作资源行的路由将在获取行之前匹配。至解决这个问题，将get行移到资源行上方，这样就可以了首先匹配。

来自http://guides.rubyonrails.org/routing.html#crud-verbs-and-actions

演示：

# beverage_locations_controller.rb
class BeverageLocationsController < ApplicationController
  def index
    render :text => params[:location_id]
  end

  def new
    render :text => 'New method'
  end
end

# config/routes.rb
Forfun::Application.routes.draw do
  controller 'beverage_locations' do
     get 'beverage_locations/new'          => 'beverage_locations#new'
     get 'beverage_locations/:location_id' => 'beverage_locations#index'
  end
end
# http://localhost:3000/beverage_locations/1234   =>  1234
# http://localhost:3000/beverage_locations/new    =>  New method

您需要交换路线的顺序，以便new操作具有首选项：

controller 'beverage_locations' do
   get 'beverage_locations/new' => 'beverage_locations#new'
   get 'beverage_locations/:location_id' => 'beverage_locations#index'
end
