ruby-on-rails - Rails 3.2.6 布线错误

Question

我是 Rails 新手，我阅读了《Head First with Rails》这本书

这是我所做的步骤:

$rails tickets

shaun@master ~/Desktop/tickets $ rails generate scaffold ticket name:string seat_id_seg:string address:text price_paid:decimal email_address:string


shaun@master ~/Desktop/tickets $ rake routes
    tickets GET    /tickets(.:format)          tickets#index
            POST   /tickets(.:format)          tickets#create
 new_ticket GET    /tickets/new(.:format)      tickets#new
edit_ticket GET    /tickets/:id/edit(.:format) tickets#edit
     ticket GET    /tickets/:id(.:format)      tickets#show
            PUT    /tickets/:id(.:format)      tickets#update
            DELETE /tickets/:id(.:format)      tickets#destroy


    shaun@master ~/Desktop/tickets $ rake db:migrate
==  CreateTickets: migrating ==================================================
-- create_table(:tickets)
   -> 0.1065s
==  CreateTickets: migrated (0.1069s) =========================================


when i try going to localhost:3000/tickets

it comes out Routing Error and says "No route matches [GET] "/tickets"

我只是按照你为新的 Rails 3.2.6 应用程序编写的方式进行操作，它对我来说工作得很好。您错过的唯一步骤是在生成脚手架后运行 rake db:migrate 。尝试一下，看看是否有效。
