Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

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:
