 ========================
 
 Rails' use of **strict naming conventions** means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.

+Rail Generating & Scaffolding 
+========================
+
+Rails' use of **strict naming conventions** means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.
+
+This means that Rails can actually do some tasks for you!
+It can actually build things and write code on your behalf...
+
+Coming from another language like PHP, this can seem like magic.
+
+## Quick reference:
+
+	rails g scaffold Post name:string title:string content:text
+	rails g controller Comments
+	rails g model Comment commenter:string body:text article:references
+
+##Rails generator
+The rails generate command uses templates designed-by-convention to create a whole lot of useful things. Running rails generate by itself gives a list of available generators:
+
+	rails generate
+
+or for super-hackers:
+
+	rails g
+
+There are a lot of generators:	
+
+**Rails:**
+
+* assets
+* controller
+* generator
+* helper
+* integration_test
+* mailer
+* migration
+* model
+* observer
+* performance_test
+* resource
+* scaffold
+* scaffold_controller
+* session_migration
+* task
+
+**Coffee:**
+
+* coffee:assets
+
+**Jquery:**
+
+* jquery:install
+
+**Js:**
+
+* js:assets
+
+
+##Scaffolding in Rails
+
+Rails' scaffolding tool is a quick way to generate some of the major pieces of code in an application. This saves a lot of time when you want to get up-and-running quickly! (*It is super cool!*)
+
+Depending on what you want to create, scaffolding can auto-generate all or a combination of:
+
+	migrations
+	models
+	views
+	controllers
+	unit_tests 
+	helpers
+	stylesheets
+	javascript
+
+There might be a few more files that it makes... I'm not sure if that's a complete list!
+
+
+##Scaffolding a whole resource
+### You are scaffolding things associated with an object (singular)	
+
+If you want to scaffold an application, you need to scaffold each resource within that application. If you wanted to make a blogging application for example - you could scaffold the whole Post resource:
+
+	rails g scaffold Post
+
+The resource name `Post` needs to be: 
+
+* UpperCamelCase 
+* **SINGULAR**
+
+**This name is going to be the name of the model, e.g. Post.** It is also going to be the name of the controller class (but pluralized), e.g. PostsController AND the name of the table (but pluralized) e.g. posts
+
+After the class name, you can add table columns and their datatypes.
+
+	rails g scaffold Post name:string title:string content:text
+
+These table columns names should be: 
+
+* lower_snake_case
+* **SINGULAR**
+
+----
+
+This is because each Post item is meant to have **one** value stored in each column.
+
+---
+
+If you ran this scaffold, it would create these all files:
+
+* db/migrate/20100207214725_create_posts.rb
+* app/models/post.rb
+* test/unit/post_test.rb
+* test/fixtures/posts.yml
+* config/routes.rb
+* app/controllers/posts_controller.rb
+* app/views/posts/index.html.erb
+* app/views/posts/edit.html.erb
+* app/views/posts/show.html.erb	
+* app/views/posts/new.html.erb
+* app/views/posts/_form.html.erb
+* test/functional/posts_controller_test.rb
+* app/helpers/posts_helper.rb
+* test/unit/helpers/posts_helper_test.rb
+* app/assets/javascripts/posts.js.coffee
+* app/assets/stylesheets/posts.css.scss
+* app/assets/stylesheets/scaffolds.css.scss
+
+Within the PostController, all of the RESTful methods will be created and they will all have their corresponding view files.
+
+After creating the migration file, in order to make the change to the database remember to run:
+
+	rake db:migrate
+
+##Generating just a controller
+### It controls lots of objects (so it is plural)
+
+Sometimes, you want to generate just a controller.
+
+	rails g controller Comments
+
+The controller name needs to be:
+
+* UpperCamelCase
+* **PLURALIZED**
+
+----
+
+This is because a controller deals with lots of examples of an object, so it should be plural.
+
+---
+
+This will make these files:
+
+* app/controllers/comments_controller.rb
+* app/views/comments/
+* test/controllers/comments_controller_test.rb
+* app/helpers/comments_helper.rb
+* test/helpers/comments_helper_test.rb
+* app/assets/javascripts/comment.js.coffee
+* app/assets/stylesheets/comment.css.scss
+
+This will **NOT** create a migration file or a model file.
+
+##Generating just a model
+### You are generating the outline of an object (singular)
+
+If you just want to create a model, you can do:
+
+	rails g model Comment
+
+* UpperCamelCase 
+* **SINGULAR**
+
+You can also add the column names to this if you want:
+
+	rails g model Comment commenter:string body:text article:references
+
+These table column names should be: 
+
+* lower_snake_case
+* **SINGULAR**
+
+
+Generating a model will create these files:
+
+* db/migrate/20140120201010_create_comments.rb
+* app/models/comment.rb
+* test/models/comment_test.rb
+* test/fixtures/comments.yml
+
+After creating the migration file, in order to make the change to the database remember to run:
+
+	rake db:migrate
