This is a fairly bare bones Rails app illustrating how to create the beginnings of a CMS UI using Rails 5, Postgres 9, and Bootstrap 4.

There is a demo app where you can log in with admin@example.com / admin.

NOTE: I have also put together a Clojure CMS REST API based on Mongodb. For a CMS with versioning a document database seems like a good fit.

• The model hierarchy is: Site -> Page -> Widget. The page/widget relationship is modeled via an array of IDs in a JSON column in Postgres. It is easier to version documents than normalized relational data models.
• There is the beginnings of a simple versioning scheme for the Page model. It saves versions in a PageVersion model.
• The Page model has a publication status and it maintains a unique url (path).
• There is a User model and login/login routes. Authentication is required for all pages.
• There is a change log (audit) for all write operations that are performed by users (editors) of the CMS

• Simplicity is a prerequisite for reliability
• Be restrictive with library dependencies. This helps with simplicity and Rails upgrades.
• Respect Rails and Ruby idioms

bundle install
bin/rake db:create db:migrate db:seed
bin/rails s
open http://localhost:3000

Create your app on heroku with the Postgres addon and then do:

heroku git:remote -a <my-heroku-app>
git push heroku master
heroku run rake db:migrate db:seed
heroku open
