FriendlyId is the "Swiss Army bulldozer" of slugging and permalink plugins for Active Record. It lets you create pretty URLs and work with human-friendly strings as if they were numeric ids.
With FriendlyId, it's easy to make your application use URLs like:
FriendlyId offers many advanced features, including:
Add this line to your application's Gemfile:
gem 'friendly_id', '~> 5.4.0'
Note: You MUST use 5.0.0 or greater for Rails 4.0+.
And then execute:
slugcolumn to the desired table (e.g.
shell rails g migration AddSlugToUsers slug:uniq
Generate the friendly configuration file and a new migration
rails generate friendly_id
Note: You can delete the
CreateFriendlyIdSlugsmigration if you won't use the slug history feature. (Read more)
Run the migration scripts
app/models/user.rbfile as the following:
class User < ApplicationRecord extend FriendlyId friendly_id :name, use: :slugged end
app/controllers/users_controller.rbfile and replace
class UserController < ApplicationController def show @user = User.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/users/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:
