Sluger

Sluger is a plugin for generating SEO friendly permalinks. It adds ability to use alphabetic ID for entities instead of numeric ID.

For instance, without sluger the helper article_url(article) returns:

http://localhost:3000/articles/1

But with sluger this helper will return:

http://localhost:3000/articles/seo-friendly-name

Add this line to your application's Gemfile:

gem 'sluger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sluger

Add a column which will store role/roles as integer:

add_column :articles, :slug, :string, null: false, limit: 150
add_index :articles, :slug, unique: true

And then tell a model that you use this gem functionality:

# app/models/article.rb
class Article < ActiveRecord::Base
  sluger :title, :slug
end

For now the gem has only one option - limit. It helps to limit a slug's length. If you set the limit all extra characters will be cut.

# app/models/article.rb
class Article < ActiveRecord::Base
  sluger :title, :slug, limit: 150
end

So you can do this:

article = Article.create!(title: 'Hello World!')
article.slug # => hello-world
article.title = 'New World!'
article.save! # => hello-world
article.slug = nil
article.save! # => new-world
article.to_param # => new-world
