JustInclude

JustInclude simply wraps included { class_eval { ... } } combo. class_eval is better then normal method ClassMethods because you can include all kind of things you normally type inside a class. Such as:

• methods
• class methods
• callbacks
• relation definitions
• act_as_*
• constans
• extends / includes etc...

Usecase

I was working on a large app where core functionality was searching. I decided that methods related with solr so searchable and wrapper on solr search are so important in my app, that they deserve to have their own file. From class point of view, functionality sill belongs to that class.

Installation

gem 'just_include'

Usage

Create a module with functionality you want to be part of other class

module FunctionalityA
   include JustInclude
   just_include do

     extend FriendlyId

     acts_as_taggable_on :skills

     searchable do
     end

     def method
     end

     def self.class_method
     end

   end
 end

Then simply include this module inside other class

class OtherClass < ActiveRecord::Base 
    include FunctionalityA
end
