CustomFields

Manage custom fields to a Mongoid document or a collection. This module is one of the core features we implemented in our custom CMS, named LocomotiveCMS. Basically, its aim is to provide to editors a way to manage extra fields to a Mongoid document through, for instance, a web UI.

The main goals:

Offering a very secure way to add, edit and delete extra fields to a Mongoid document.
Scoping the modifications added to a Mongoid document, so that other documents of the same class won't be updated.

Requirements

MongoDB 3.x
Mongoid 5.x
ActiveSupport 4.2.x

Examples

On a `has_many` relationship

class Company
  include CustomFields::Source

  has_many :employees

  custom_fields_for :employees
end

class Employee
  include CustomFields::Target

  field :name, String

  belongs_to :company, inverse_of: :employees
end

company = Company.new
company.employees_custom_fields.build label: 'His/her position', name: 'position', type: 'string', required: true

company.save

company.employees.build name: 'Michael Scott', position: 'Regional manager'

another_company = Company.new
employee = another_company.employees.build
employee.position # Returns a `not defined method` error

On the class itself

IN PROGRESS

class Company
  custom_fields_for_itself
end

company = Company.new
company.self_metadata_custom_fields.build label: 'Shipping Address', name: 'address', type: 'text'

company.save

company.self_metadata.address = '700 S Laflin, 60607 Chicago'

another_company = Company.new
other_company.self_metadata.address # Returns a `not defined method` error
