Ruby on Rails
Vriendelijk ID

Invoering

Rails Snelstart

rails new my_app
cd my_app

Gemfile

gem 'friendly_id', '~> 5.1.0' # Note: You MUST use 5.0.0 or greater for Rails 4.0+
rails generate friendly_id
rails generate scaffold user name:string slug:string:uniq
rake db:migrate

app / modellen / user.rb bewerken

class User < ApplicationRecord
  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])

rails server
GET 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:
User.find_each(&:save)

Finders are no longer overridden by default. If you want to do friendly finds, you must do Model.friendly.find rather than Model.find. You can however restore FriendlyId 4-style finders by using the :finders addon


friendly_id :foo, use: :slugged # you must do MyClass.friendly.find('bar')
#or...
friendly_id :foo, use: [:slugged, :finders] # you can now do MyClass.find('bar')

Een nieuwe "kandidaten" -functionaliteit die het gemakkelijk maakt om een lijst met alternatieve slakken op te stellen die kunnen worden gebruikt om records op unieke wijze te onderscheiden, in plaats van een reeks toe te voegen. Bijvoorbeeld:

class Restaurant < ActiveRecord::Base
  extend FriendlyId
  friendly_id :slug_candidates, use: :slugged

  # Try building a slug based on the following fields in
  # increasing order of specificity.
  def slug_candidates
    [
      :name,
      [:name, :city],
      [:name, :street, :city],
      [:name, :street_number, :street, :city]
    ]
  end
end

Slug limiet lengte instellen met friendly_id gem?

def normalize_friendly_id(string)
   super[0..40]
end
