This is an attempt to a mountable rails engine for SCORM RTE.

First, add the gem to your Gemfile.

gem 'scorm_rte', git: 'https://github.com/pukei/scorm_rte.git'

And, bundle.

bundle install

Then, mount the engine to your application.

# Add this line to routes.rb
mount ScormRte::Engine, at: 'scorm_rte'
# Or, any custom mount point
mount ScormRte::Engine, at: 'this_is_soo_coool'

This will provide some actions to take care of the RTE.

/scorm_rte/stores                # POST
/scorm_rte/stores/fetch          # GET
# Or
/this_is_soo_coool/stores        # POST
/this_is_soo_coool/stores/fetch  # GET

Now, copy the migrations from the engine to the application.

[bundle exec] rake scorm_rte:install:migrations
[bundle exec] rake db:migrate

Make the javascript RTE available to the application

// Add the following line to application.js
//= require scorm_rte/rte

Or, you can add this line to config/initializers/assets.rb

Rails.application.config.assets.precompile += %w( scorm_rte/rte.js )

And, make it available to the subsequent views

<%= javascript_include_tag 'scorm_rte/rte' %>

Or, better still you can copy the RTE js to the application and handle it yourself

[bundle exec] rake scorm_rte:copy_rte

Well, almost done.!!! One last thing, that is to assign a unique ID to each instance of the SCO. This will be be used to query the db to keep track of everything that's going on at each User/SCO level.

Use the controller helper assign_sco_instance_id(sco_instance_id).

# This can be achieved in some way similar to this
class LmsController < ApplicationController
  def launch_scorm_player
    assign_sco_instance_id(sco_instance_id)

    # Rest of the code follows
    ...
  end

  private

  def sco_instance_id
    "#{current_user.id}:#{current_course.id}"
  end
end

• Add tests
• Handle custom mount point
• Allow export of RTE js to the host application for customization
• Possibly implement error and diagnostics or, switch to TinCan perhaps :)
