What friendly gem can do?

Friendly_Id 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.

Rails Quicksetup

#Lets include this in the Gemfile
gem 'friendly_id', '~> 5.1.0' # Note: You MUST use 5.0.0 or greater for Rails 4.0+

rails generate friendly_id
rake db:migrate

You can use it in any model for example lets take the user model first:

# edit app/models/user.rb
class User < ActiveRecord::Base
  extend FriendlyId
  friendly_id :name, use: :slugged
end

User.create! name: "Joe Schmoe"

# Change User.find to User.friendly.find in your controller
User.friendly.find(params[:id])

Now, the thing you notice here is that what if we want a custom URL besides the name, then you can use something like this:

class Event < ActiveRecord::Base
	extend FriendlyId
  	friendly_id :cus_name, use: :slugged

	
	def custome_name 
         #using this function will make URL with description+name fields in events table
          description+ename	
	end

	def cus_name #randon string will be generated of 5 characters 
          random_str
	end

	def random_str leng=5 
	    str=''
  		leng.times{str+=([*('a'..'z'), *(1..9)]).shuffle.sample.to_s}
  		str
	end



end

rails server

# 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:
User.find_each(&:save)
