Coursemology is an open source gamified learning platform that enables educators to increase student engagement and make learning fun.

Setting up Coursemology

System Requirements

  1. Ruby (= 3.0.5)
  2. Ruby on Rails
  3. PostgreSQL (>= 9.5)
  4. ImageMagick or GraphicsMagick (For MiniMagick - if PDF processing doesn't work for the import of scribing questions, download Ghostscript)
  5. Node.js (v18 LTS)
  6. Yarn

Coursemology uses Ruby on Rails. In addition, some front-end components use React.js. This guide written by the awesome people at GoRails should help you to get started on Ruby on Rails.

Getting Started

  1. We use submodules in the git repo; use this command to update submodules:
   $ git submodule update --init --recursive
  1. Download bundler to install dependencies
   $ gem install bundler:2.2.33
  1. Install ruby dependencies
   $ bundle config set --local without 'ci:production'
   $ bundle install
  1. Install javascript dependencies
   $ cd client && yarn; cd -
  1. Create and seed the database
   $ bundle exec rake db:setup
  1. Start webpack and the development app server
   $ foreman start

Or if you are not using foreman:

   # Start the webpack dev server:
   $ cd client && yarn build:development

Either way, run this command to compile the assets before running the test suite.

   $ cd client && yarn build:test
  1. You're all set! Simply login with the default username and password:

Multi Tenancy

To make sure that multi tenancy works correctly for you, change the default host in config/application.rb before deploying:

config.x.default_host = ''

Opening Reminder Emails

Email reminders for items which are about to start are sent via a cronjob which should be run once an hour. See config/initializers/sidekiq.rb and config/schedule.yml for sample configuration which assumes that the Sidekiq and Sidekiq-Cron gems are used.

If you use a different job scheduler, edit those files so your favourite job scheduler invokes the ConsolidatedItemEmailJob job once an hour.
