Ruby on Rails app not connecting

Question

I can't connect to my localhost using Ruby on Rails. I've made fresh installs (even using explicit commands like rails new test_app -d mysql ) but it never connects to the page. When I try localhost:3000 there's just a white page and the Firefox loading icon doesn't stop. When I first installed it, the startup screen loaded fine - but after adding resources it just hangs. I can add resources to the database fine using rake db:migrate . Here's my database.yml:

development:
  adapter: mysql2
  host: localhost
  username: root
  password: root
  database: limetree
  socket: /tmp/mysql.sock

The test and production environments are the same setup. The weird thing is that I can add resources/tables to my database using the console - it's just my browser doesn't seem to be able to connect to the database using the app's controllers. I also think it might be a routing problem. The only line I changed in my routes.rb is:

root :to => "home#index"

Does anybody know why my Rails app isn't loading?

UPDATE:

Because I was running out-of-date versions (Ruby 1.8.7 and Rails 3.0.1) I reinstalled everything from scratch with the latest software. There was a minor issue with the rake gem which was resolved by reinstalling it. Everything now works fine.

Answer 1

尝试在配置文件中输入password: "root"

Answer 2

转到http：// localhost：3000 ，在Rails应用程序目录中打开文件log / development.log ，然后查看是否有任何有用的消息。

Answer 3

Make sure your MySQL server is actually running. You could try to use this in the routes file:

match ':controller(/:action(/:id(.:format)))'

Answer 4

既然已经设置了主页，请确保您有一个名为“ home”的控制器，并且有一个名为“ index”的操作。
