rails 3.2.6 routing error

问题描述:

i am new to rails, i followed the book "head first with rails"

this are the steps i did:

$rails tickets

[email protected] ~/Desktop/tickets $ rails generate scaffold ticket name:string seat_id_seg:string address:text price_paid:decimal email_address:string

[email protected] ~/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

[email protected] ~/Desktop/tickets $ rake db:migrate

== CreateTickets: migrating ==================================================

-- create_table(:tickets)

-> 0.1065s

== CreateTickets: migrated (0.1069s) =========================================

when i try going to localhost:3000/tickets

how do i solve this? i want to be able to see the main page and with all the links to go to index, create new ticket, edit, show, update and delete.

网友答案:

I just did exactly as you wrote for a new Rails 3.2.6 app, and it worked fine for me. The only step you missed was to run rake db:migrate after your scaffold generation. Try that and see if it works.
