Withardry

Install

gem "withardry"

Usage

class Post < ActiveRecord::Base      
  withardry :title

  # exactly same as
  # scope :with_title, lambda { |t| where(:title => t) }

  friendly_url
  # same as to_param with model id and name attribute

  friendly_url :title
  # same as to_param with model id and title attribute
end

Now use this inside your app:

Post.with_title("Some title")

post = Post.create(:title => "Title Example")
post.to_param # => "1-title-example"

Sure, it can handle some options

class Post < ActiveRecord::Base
  belongs_to :user

  withardry :user, :prefix => "by", :as => "user_id"

  // exactly same as
  // scope :by_user, lambda {|u| where(:user_id => u) }
end

And then anywhere in your app

Post.by_user(some_user_id)

Todo

• Ensure that tests work with Rails 3
• Add support of relations in withardry method (e.g. use of withardry :user is equal to withardry :user_id if there is a relation with User)
