GO-FOOD - GO-SCHOLAR RoR

Simplified GO-FOOD application based on website using Ruby on Rails. One of many projects in GO-SCHOLAR Ruby on Rails class. (Oct-Dec 2017)

Important Notes

This application using Ruby on Rails 5.1.4 on Linux Ubuntu 16.04 (Xenial). There are some important notes :

RoR using MVC Architecture
rails new go-food -> Creating new ruby on rails project named go-food
rails server -> starting rails server in development environment (default port : 3000)
rails server -e production -> starting rails server in production environment (will need some extra configurations)
If execjs error occurs when starting server, try to uncomment gem 'therubyracer' in Gemfile, then execute bundle and start server again.
rails generate ... -> rails command to create/generate many things such as controller, model, view, migration, etc. for example rails generate controller home hello will create a controller named home_controller with action method hello
Migration files are used to generate query to create and manipulate tables
In rails convention, model name is singular and start with one uppercase letter followed by table name in plural and all letter in downcase. Example : model User followed by table users
If rails generate a model, it will create a migration file automatically
rails console -> enter in rails console, doing some debugging process:
rails db:create -> for initial database creation
rails db:migrate -> doing database migration of migration files
rails db:rollback -> Revert/undo last migration process
<% something %> -> process something without display it to the screen, i.e : if, each, etc
<%= something %> -> display it to the screen, i.e : display a variable
