How to Generate SEO Friendly URL in Rails 3.x

SEO friendly URLs are more important to make a page popular & search engines to crawl.

FriendlyId is the slugging and permalink plug-in for Ruby on Rails. It allows you to create pretty URLs and work with human-friendly strings.

The URLs created by slug are very useful for SEO. It is designed for generation of URL slug and history maintenance.

Steps to create Pretty URLs:

Step#1

Include gem in your Gem file:

gem 'friendly_id'

Then run bundle install.

Step#2

Modify your model on which you want the pretty URL:

extend FriendlyId
 
friendly_id :title, use: :slugged

Step#3

Add the slug column in your migration file to add it on the table

add_column :articles, :slug, :string

Then run

rake db:migrate

Now if you create an article with Title like “This is a demo title for testing”,
it will create a SEO friendly URL like “this-is-a-demo-title-for-testing” and will
save into the articles table under slug column.
