Trek::Fragmentable

Composes a record from reusable fragments, based on a configuration matrix mapping record keys to fragment ids.

Configuration

# page_fragments configuration
page_fragments:
  matrix:
    home: [1, 2, 3]
    about: [4, 5]

Methods

Method	Purpose
fragments	the Fragment records configured for this record's key
fragments_attributes=	bulk-updates fragments from nested form attributes

Usage

class Page < ApplicationRecord
  include Trek::Fragmentable
end

page = Page.find_by(key: "home")
page.fragments # => [Fragment(1), Fragment(2), Fragment(3)]

This is what powers the fragment editing UI on page forms in the admin.
