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?

With the most popular text editors and IDEs you can search for a string across all project files. If by any chance you are using Sublime Text, you can do it with the keyboard shortcut Ctrl+⇧+F or using Find > Find in files, as explained here.

Remember that your app name might appear in the following formats:

• MyAppName (in application.rb)
• my-app-name
• my_app_name
• My App Name (in layouts)

In my case, for a Rails 5.1.6 app I had to edit the following files:

• config/application.rb
• config/cable.yml
• config/database.yml (if you want to change database names)
• config/environments/production.rb
• app/views/layouts/application.html.erb
• package.json
• app/mailers/* (change email from addresses)
• config/initializers/devise.rb (config.mailer_sender)
