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 Locomotive.
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 / 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.
ActiveSupport 3.1.1, MongoDB 2.0 and Mongoid 2.3.2
On a has_many relationship
class Company embeds_many :employees
custom_fields_for :employees end
class Employee field :name, String
embedded_in :company, :inverse_of => :employees end
company = Company.new company.employees_custom_fields.build :label => 'His/her position', :_alias => 'position', :kind => 'string', :required => true
company.employees.build :name => 'Michael Scott', :position => 'Regional manager'
another_company = Company.new employee = company.employees.build employee.position # returns a "not defined method" error
On the class itself
class Company custom_fields_for_itself end
company = Company.new company.self_metadata_custom_fields.build :label => 'Shipping Address', :_alias => 'address', :kind => 'text'
company.self_metadata.address = '700 S Laflin, 60607 Chicago'
another_company = Company.new other_company.self_metadata.address # returns a "not defined method" error
