How to Begin a MVC Ruby on Rails project

Creating a Model

• rails g model
• rails g scaffold ClassName attr_1:datatype attr_2:datatype
  • eg rails g scaffold Entry meal_type:string calories:integer proteins:integer carbs:integer fats:integer
• created_at & updated_at column is created automatically+
  • after creating the scaffold, there is a migration file in db/migrate which needs to be dealt with
    • using rails db:migrate will create the table

Finding Routes on the Rails server

• launch the app with rails s
  • go to http://localhost:3000/rails/info/routes

Installing Dependencies

• Use "bundle add name" or add to the "Gemfile" like a package json
• just call "bundle" to do like a "npm install"

Initializing Routes

• Inside of the config/routes.rb
  • root to: "entries#index"
  • will route to the entries controller's index action
    • app/controllers/entries_controller.rb

Activating Bulma CSS Framework

• Add responsive viewport meta tag
• and stylesheet from the starter template
  • to app/views/layouts/application.html.erb

Partial Templates

• name file starting with _ like "_header.html.erb"
  • then use <%= render "shared/header" %> to render it out in html

Linking

• <%= link_to "Create a New Entry", new_entry_path, class: "button is-success" %>
  • link_to "Words to show", rails path, class: "classname"

Initializer

• Added this time_format.rb in config/initializers
  • provides a new function upon app startup

Book keeping of params

• use <%= params %> to show the params of that page, such as what controller, view and ID are active
