Cloning Twitter with Rails 4

I posted this Rails 4 Development Map for myself to review in the future. Also, this repo helped me earn my first + second SoftEng jobs!!!

1. The Must-Know Core:

   a. RAILS command-line: rails generate xxx, rails server, rails console

   • RAKE tasks: db:migrate (VERSION=0), db:rollback, test:prepare, db:reset, assets:precompile
   • Git & Heroku

   b. Flexible DB-schema with "migrations"

   c. MODEL as a soft DB-manipulater with: "validations", "associations", "callbacks", has_secure_password, and business logics

   d. RAILS app-dev as RESOURCE manipulation via Controller-and-View(s):

   • CONTROLLER: RESTful & custom methods linked with VIEW(s), execute application logics, have "strong parameters" and "filters"
   • VIEW(s): "layouts", "templates", and "partials" with Bootstrap-HTML
   • HELPER(s): extracting codes to achieve DRY

   e. Different ROUTING(s):

   • RESTful routes
   • custom routes
   • named routes

2. Additions for a Good Junior:

   a. TDD with RSpec:

   • 3 test levels: models, helpers, & requests
   • spec/*_helper.rb configs
   • spec/support functions
   • factory_girl
   • capybara

   b. RAKE task: db:populate

3. Advanced(s) for a Senior/Full-stack:

   • Gems Hunting
   • CSS styling
   • JS-related stuffs
   • More configs: config/environments, configs/initializers & config/application.rb.
