How to change a Ruby on Rails application name?

Question

I have a Ruby on Rails application that was created using:

rails new old_name -d mysql

Now I want to change the application name to be

Answer 1

in Rails 3, the application class is defined in config/application.rb, and referred to in your environment files (config/environment.rb, config/environments/*.rb) and config/routes.rb. I think that's it, but you should find out pretty quickly from rails server if you missed one. :)

• config/application.rb
• config/enviroment.rb
• config/environments/*.rb
• config/routes.rb

That said, unless you've got a very specific reason for wanting it changed, I wouldn't bother. Doesn't really affect the application in any other way.

Answer 2

On rails 4

Add

gem 'rename'

to Gemfile then do

bundle install

After bundle install

rails g rename:app_to name_of_app
