Question

出于某种原因，这些URL都在不应该的时候路由到同一个文件，在输入无效的URL时我注意到了另一件事，例如localhost：3000 / topics / inexjojvnsjg它只是保持不变页。

这是我尝试访问网址时我的rails控制台告诉我的内容 localhost:3000/topics/index

Started GET "/topics/index" for ::1 at 2015-02-06 17:33:07 -0700
Processing by TopicsController#show as HTML
Parameters: {"id"=>"index"}
Rendered topics/show.html.erb within layouts/application (0.1ms)
User Load (0.8ms)  SELECT  "users".* FROM "users" WHERE "users"."id" =$1   ORDER BY "users"."id" ASC LIMIT 1  [["id", 1]]
Completed 200 OK in 98ms (Views: 96.5ms | ActiveRecord: 0.8ms)

这是我的路线档....

Rails.application.routes.draw do

devise_for :users
get 'welcome/index'
get 'welcome/about'

# get "topics/index"
# get "topics/show"
# get "topics/new"
# get "topics/edit"
#for some reason, using resources:topics, index and show both route to  show
resources :topics

root to: 'welcome#index'

post :incoming, to: 'incoming#create'
end

以下是关键信息：

Started GET "/topics/index" for ::1 at 2015-02-06 17:33:07 -0700
Processing by TopicsController#show as HTML
Parameters: {"id"=>"index"}

TopicsController的:index网址是＆＃34; / topics＆＃34;。

TopicsController的:show网址是＆＃34; / topics /：id＆＃34;或＆＃34; / topics / 1＆＃34;，其中网址的最后一部分与params[:id]相关联。使用网址＆＃34; / topics / 1＆＃34; :id = 1。

所以当你去网址＆＃34; / topics / index＆＃34;由于＆＃34;索引＆＃34;您将进入:show行动网址的一部分。您只需将:id设置为＆＃34;索引＆＃34;而不是整数:id。您可以在此处粘贴的输出中看到：

Parameters: {"id"=>"index"}

TLDR：＆＃34; / topics / index＆＃34;是一个将通过Rails路由器的路由但是路由无效，因为:id是一个字符串＆＃34;索引＆＃34;。

localhost：3000 / topics / index和localhost：3000 / topics /显示同一show.html文件的两条路由
