Method: Mongoid::Factory#execute_from_db

Defined in:

lib/mongoid/factory.rb

#execute_from_db(klass, attributes = nil, criteria = nil, selected_fields = nil, execute_callbacks: Threaded.execute_callbacks?) ⇒ Document

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Execute from_db.

Parameters:

• klass (Class) —

  The class to instantiate from if _type is not present.

• attributes (Hash) (defaults to: nil) —

  The document attributes.

• criteria (Criteria) (defaults to: nil) —

  Optional criteria object.

• selected_fields (Hash) (defaults to: nil) —

  Fields which were retrieved via #only. If selected_fields are specified, fields not listed in it will not be accessible in the returned document.

• execute_callbacks (true | false) (defaults to: Threaded.execute_callbacks?) —

  Whether this method should invoke the callbacks. If true, the callbacks will be invoked normally. If false, the callbacks will be stored in the pending_callbacks list and caller is responsible for invoking run_pending_callbacks at a later time. Use this option to defer callback execution until the entire object graph containing embedded associations is constructed.

Returns:

• (Document) —

  The instantiated document.
