Builder

Responsibility

  • Converts params into a template for creating and updating items.

include magic

class ContactCurator < BaseCurator
  include Omicron.authorization(ContactAuthorizer)

  def create_action
    pipe(default_response, :through => [
      :build, :validate, :authorize_to_write, :create,
      :apply_readables, :publish_create, :decorate
    ])
  end

  def update_action
    pipe(default_response, :through => [
      :find, :build, :remove_shared_access, :validate,
      :authorize_to_update, :update, :update_user, :apply_readables,
      :publish_update, :decorate
    ])
  end
end

We use the include magic to
inject build into the curator. 

Concepts

  • build

  • create_template

  • update_template

  • model

  • deprecated_attributes

class ContactBuilder < MasterBuilder
  private

  def deprecated_attributes
    {
      :hide_address => :is_address_hidden
    }
  end

  def model
    Contact
  end

  def create_template
    process_template(:allowed => [
      :label, :position, :address_street1, :address_street2,
      :address_city, :address_state, :address_zip, :address_country,
      :first_name, :last_name, :is_address_hidden, :allow_shared_access, 
      :member_id
    ])
  end

  def update_template
    process_template(:allowed => [
      :label, :position, :address_street1, :address_street2,
      :address_city, :address_state, :address_zip, :address_country,
      :first_name, :last_name, :is_address_hidden, :allow_shared_access
    ])
  end
end

build

Build takes the params and combines it with the template to either create a new item or update an existing item in the collection.
