How to rename rails 4 app?

Question

rails plugin install git://github.com/get/Rename.git will allow us to rename only rails 3 app

Is there any gem available to rename Rails 4 app.

If not, suggest me the better way to rename.

Answer 1

I just used this rename gem in a basic rails 4 app:

https://github.com/morshedalam/rename

This is quite a bit different to get's version.

Easy enough to use:

Add this to Gemfile:

gem 'rename'

And run:

rails g rename:app_to NewName

Seemed to the trick,
It also updated my rubymine .idea project settings :)

In Rails 5.x, doing it manually

using ag (https://github.com/ggreer/the_silver_searcher), there are files that use the default folder name (if generated via rails new .)

three basic files, relative to root of project, need to be updated:

• config/cable.yml > channel_prefix:
• config/environments/production.rb > # config.active_job.queue_name_prefix
• package.json > name

There are sure to be more locations as mentioned previously such as database etc. Hope this helps.

Since rails 4.1.x, if you want to rename your application, the only two files you need to modify are config/application.rb:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module YourApplicationName # <-- rename it here
   class Application < Rails::Application
     ...
   end
end

and config/initializers/session_store.rb (optional):

# Be sure to restart your server when you modify this file.

Rails.application.config.session_store :cookie_store, key: '_your_application_name_session' # <-- rename the key

---

For Rails 4.0.x you can use the rename gem and execute the following command:

rails g rename:app_to New-Name

This will update the necessary files for you:

old/ (master)  › rails g rename:app_to new
Search and replace module in to...
    gsub  config.ru
    gsub  Gemfile
    gsub  Gemfile.lock
    gsub  Rakefile
    gsub  README.md
    gsub  config/application.rb
    gsub  config/boot.rb
    gsub  config/environment.rb

    gsub  config/environments/production.rb
    gsub  config/environments/test.rb
    gsub  config/initializers/backtrace_silencers.rb
    gsub  config/initializers/filter_parameter_logging.rb
    gsub  config/initializers/inflections.rb
    gsub  config/initializers/load_class_extensions.rb
    gsub  config/initializers/mime_types.rb
    gsub  config/initializers/secret_token.rb
    gsub  config/initializers/session_store.rb
    gsub  config/initializers/update.rb
    gsub  config/initializers/wrap_parameters.rb
    gsub  config/routes.rb
    gsub  config/initializers/session_store.rb

For Rails 5

Require

• config/application.rb change the module name

Optional

• config/initializers/session_store.rb (in Rails.application.config.session_store) change the session name
• app/views/layouts/application.html.erb You can change the <title>...</title>, if it is not already done

Answer 5

In Rails 4.2 just change in application config file

config/application.rb

and config/initializers/session_store.rb (optional):

Rails.application.config.session_store :cookie_store, key: '_your_application_name_session' # <-- rename the key

then restart your server.

That's it!

Here is a gem specifically for Rails 4 https://github.com/negativetwelve/rails-rename (I haven't used it but it seems fine)

The other gems listed here only target Rails 3
