Random Notes⚓︎

  • Ruby on Rails follows the Model-Controller-View (MVC) architectural pattern: models are database tables, controllers are actions performed on the models, views are HTML pages rendered on the browser
  • To create a controller, rails generate controller NAME [action]
  • Views templates have .html.erb extensions
  • Django's corresponding URLs are called routes (\config\routes.rb)
  • The root route can be referenced to a specific action of a specific controller (like root CONTROLLERNAME#ACTION)
  • To check the routes in this Rails project, run rails routes or go to http://127.0.0.1:3000/rails/info/routes
  • A resource is generally anything that you want to reach with a URI and perform CRUD operations on. Simply put, it's a database table which is represented by a model, and acted on through a controller.
