Question

I’ve created a simple mountable application in rails 3.1.3 using command:

$ rails plugin new appToMount –mountable

Than I added some MVC to it. And now I want to mount it to another normal Rails application. The problem is I have no idea how to do this. I tried asking google, but I failed. There are plenty of examples how to create mountable app, but none explaining how to mount it.

You have to add it to the config/routes.rb of your rails app. Something like the following:

mount AppToMount::Engine, :at => '/'

And I recommend you to package your engine as a gem. You can use bundler to create the new gem with the command

bundle new app_to_mount

And finally, you should add the Gem to your gemfile, using the path option. Like in the following:

gem 'app_to_mount', path: '/your/home/app_to_mount'
