StaticAssociation

Adds basic ActiveRecord-like associations to static data.

Installation

Add this line to your application's Gemfile:

gem "static_association"

And then execute:

$ bundle

Or install it yourself as:

$ gem install static_association

Usage

Static Models

Create your static association class:

class Day
  include StaticAssociation

  attr_accessor :name

  record id: 0 do |day|
    day.name = :monday
  end
end

Calling record will allow you to create an instance of this static model, a unique id is mandatory. The newly created object is yielded to the passed block.

The Day class will gain .all, .find, .find_by_id, and .where methods.

• The .all method returns all the static records defined in the class.
• The .find method accepts a single id and returns the matching record. If the record does not exist, a RecordNotFound error is raised.
• The .find_by_id method behaves similarly to the .find method, except it returns nil when a record does not exist.
• The .where method accepts an array of ids and returns all records with matching ids.

Associations

Currently just a 'belongs to' association can be created. This behaviour can be mixed into an ActiveRecord model:

class Event < ActiveRecord::Base
  extend StaticAssociation::AssociationHelpers

  belongs_to_static :day
end

This assumes your model has a field day_id.
