How to rename a rails 5 application?

Question

Is the rename gem the best way to rename my rails 5 app?

Also, is there any notes I have to keep in mind when renaming my app?

Answer 1

The following worked for me:

1. Add gem "rename" to your Gemfile
2. bundle
3. rails g rename:into NEW_NAME

Note that this will create a new folder with the new app name, move all the files to the new folder and remove the old app. So take a back if you need to. The files that are modified are:

gsub  Gemfile.lock
gsub  Gemfile
gsub  config.ru
gsub  README.md
gsub  package.json
gsub  Rakefile
gsub  config/puma.rb
gsub  config/environments/production.rb
gsub  config/environments/test.rb
gsub  config/environments/development.rb
gsub  config/routes.rb
gsub  config/initializers/assets.rb
gsub  config/initializers/cookies_serializer.rb
gsub  config/initializers/content_security_policy.rb
gsub  config/initializers/application_controller_renderer.rb
gsub  config/initializers/wrap_parameters.rb
gsub  config/initializers/mime_types.rb
gsub  config/initializers/backtrace_silencers.rb
gsub  config/initializers/filter_parameter_logging.rb
gsub  config/initializers/inflections.rb
gsub  config/application.rb
gsub  config/spring.rb
gsub  config/boot.rb
gsub  config/environment.rb
gsub  config/initializers/session_store.rb
