Hi this is my first time with Rails and I’m having problems getting it to work properly. In the Database.yml file I have set up the following - development: adapter: mysql database: cars username: \*\*\*\*\* password: \*\*\*\*\* socket: /path/to/your/mysql.sock host: \*\*\*\*\* But, when I launch the controler it says - NameError in Add\_car#index uninitialized constant Car Where am I going wrong, as the database is not on localhost is there anything wrong in what I have done? ---

If your MySQL server is not on localhost, you probably should connect via a hostname and a port number (usually 3306), not by specifying a socket, just like in any other environment. Read the comments in the database.yml, which gives an example. Look at how you connect to that MySQL server from your machine with other tools. Those are the settings you should use. However, you may be happiest developing with a local database so you can work without a net connection at all if need be.

Thanks for the reply! 🙂 I’m afraid it has to be done through the web database, as it eventually has to be moved to another machine and the database is already set-up. I’ve put the same into in what I use to connect though MySQL front and it still does nothing with the Scaffold Cars command in the AddCar controller. ☹ database.yml - development: adapter: mysql database: cars username: \*\*\* password: \*\*\* host: _ **.\*\*\*.\*\*\*.\*\*\*.** _ port: 3306 * * * Error message - uninitialized constant Car RAILS\_ROOT: ./script/…/config/… C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/dependencies.rb:200:in `const_missing' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/core_ext/string/../../inflector.rb:149:in`constantize’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/core\_ext/string/inflections.rb:52:in `constantize' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/pagination.rb:186:in`paginator\_and\_collection\_for’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/pagination.rb:124:in `paginate' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/scaffolding.rb:101:in`list’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/scaffolding.rb:94:in `index' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:853:in`perform\_action\_without\_filters’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/filters.rb:332:in `perform_action_without_benchmark' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/benchmarking.rb:69:in`perform\_action\_without\_rescue’ C:/INSTAN~1.0/ruby/lib/ruby/1.8/benchmark.rb:293:in `measure' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/benchmarking.rb:69:in`perform\_action\_without\_rescue’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/rescue.rb:82:in `perform_action' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:369:in`process\_without\_session\_management\_support’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/session\_management.rb:116:in `process' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/dispatcher.rb:38:in`dispatch’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick\_server.rb:117:in `handle_dispatch' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick_server.rb:83:in`service’ C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/httpserver.rb:104:in `service' C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/httpserver.rb:65:in`run’ C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:173:in `start_thread' C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:162:in`start\_thread’ C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:95:in `start' C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:92:in`start’ C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:23:in `start' C:/INSTAN~1.0/ruby/lib/ruby/1.8/webrick/server.rb:82:in`start’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick\_server.rb:69:in `dispatch' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/servers/webrick.rb:59 C:/INSTAN~1.0/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/dependencies.rb:214:in `require' C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/server.rb:28 C:/INSTAN~1.0/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’ C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/dependencies.rb:214:in `require’ script/server:3 This error occured while loading the following files: car.rb ---

Can we see your schema for the cars table and also the contents of your controller and your model? I’d like some confirmation that you have a schema called cars and a table called cars in place, for starters.

Try calling your database cars\_development like this: - database: cars\_development that _might_ work
