Notes: $ rails new blogger The generator has created a Rails application for you. Let’s figure out what’s in there. Looking at the project root, we have these folders: -app - This is where 98% of your effort will go. It contains subfolders which will hold most of the code you write including Models, Controllers, Views, Helpers, JavaScript, etc. -bin - This is where your app’s executables are stored: bundle, rails, rake, and spring. -config - Control the environment settings for your application. It also includes the initializers subfolder which holds items to be run on startup. -db - Will eventually have a migrations subfolder where your migrations, used to structure the database, will be stored. When using SQLite3, as is the Rails default, the database file will also be stored in this folder. -lib - This folder is to store code you control that is reusable outside the project. -log - Log files, one for each environment (development, test, production) -public - Static files can be stored and accessed from here, but all the interesting things (JavaScript, Images, CSS) have been moved up to app since Rails 3.1 -test - If your project is using the default Test::Unit testing library, the tests will live here -tmp - Temporary cached files -vendor - Infrequently used, this folder is to store code you do not control. With Bundler and Rubygems, we generally don’t need anything in here during development.
$ bin/rails console #to get to the console

$ bin/rails generate model Article We’re running the generate script, telling it to create a model, and naming that model Article. From that information, Rails creates the following files: -db/migrate/(some_time_stamp)_create_articles.rb : A database migration to create the articles table -app/models/article.rb : The file that will hold the model code -test/models/article_test.rb : A file to hold unit tests for Article -test/fixtures/articles.yml : A fixtures file to assist with unit testing
#After editing the db/migrate/(some_time_stamp)_create_articles.rb to add your model fields $ bin/rake db:migrate
$ bin/rails generate controller articles The output shows that the generator created several files/folders for you: -app/controllers/articles_controller.rb : The controller file itself -app/views/articles : The directory to contain the controller’s view templates -test/controllers/articles_controller_test.rb : The controller’s unit tests file -app/helpers/articles_helper.rb : A helper file to assist with the views (discussed later) -test/helpers/articles_helper_test.rb : The helper’s unit test file -app/assets/javascripts/articles.js.coffee : A CoffeeScript file for this controller -app/assets/stylesheets/articles.css.scss : An SCSS stylesheet for this controller
SCAFFOLD for MVC
$ bin/rails generate scaffold_controller Author username:string email:string password:password password_confirmation:password Rails has two scaffold generators: scaffold and scaffold_controller. The scaffold generator generates the model, controller and views. The scaffold_controller will generate the controller and views. We are generating a scaffold_controller instead of scaffold because Sorcery has already defined for us an Author model.
