Friendly_id gem in Rails

What is Friendly_id gem?

.FriendlyId is the “Swiss Army bulldozer” of slugging and permalink plugins for ActiveRecord. It allows you to create pretty URL's and work with human-friendlystrings as if they were numeric ids for ActiveRecord models. 

Usage

Add this line to your application's Gemfile:

gem 'friendly_id', '~> 5.2.4' # Note: You MUST use 5.0.0 or greater for Rails 4.0+

And then execute:

bundle install

Add a slug column to the desired table (e.g. Users)

rails g migration AddSlugToProducts slug:uniq

Generate the friendly configuration file and a new migration

rails generate friendly_id

Note: You can delete the CreateFriendlyIdSlugs migration if you won't use the slug history feature. (Read more)

Run the migration scripts

rails db:migrate

Edit the app/models/product.rb file as the following:

class Product < ApplicationRecord
  extend FriendlyId
  friendly_id :name, use: :slugged
end

Edit the app/controllers/users_controller.rb file and replace User.find by User.friendly.find

class ProductController < ApplicationController
  def show
    @product = Product.friendly.find(params[:id])
  end
end

Now when you create a new user like the following:

User.create! name: "Joe Schmoe"

You can then access the user show page using the URL http://localhost:3000/products/joe-schmoe.

If you're adding FriendlyId to an existing app and need to generate slugs for existing users, do this from the console, runner, or add a Rake task:

Product.find_each(&:save)
