#Sorting a Hash I wanted to understand what happened under the hood when something like

hash.sort { |a, b| b[1] <=> a[1] }

is called. If you can't answer, you might want to read.
I'll be as basic as possible (I don't know much anyway...) so it should be understandable.

First let's begin by saying that we will be working on this hash

Todo.rb

Todo.rb is a simple command-line tool for managing todos. It's minimal, straightforward, and you can use it with your favorite text editor.

Getting Started

Todo.rb doesn't require any third-party gems so you can copy the file anywhere and use it as long as it's executable:

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

	<!-- Some form -->
	<div data-controller="auto-grow-textarea">
	<%= form.text_area :body, cols: 20, row: 2, placeholder: 'Bir yorum yazın...', class:'form-control', data: { action: 'input->auto-grow-textarea#resize', target: 'auto-grow-textarea.input' } %>
	</div>
	<!-- Some form continued -->

	NET START postgresql-x64-9.3 (64-bit windows)
	NET STOP postgresql-x64-9.3 (64-bit windows)

	NET START postgresql-9.3 (32-bit windows)
	NET STOP postgresql-9.3 (32-bit windows)


	Note: This is for Windows 7. Replace 9.3 with your version of PostgreSQL version.
