Currently, the following code raises Mongoid::Errors::DocumentNotFound
class Person include Mongoid::Document embeds_many :phones accepts_nested_attributes_for :phones end class Phone include Mongoid::Document embedded_in :person end person = Person.create! person.update_attributes!(phones_attributes: [{ id: 'a' * 24, _destroy: true }]) #=> raises Mongoid::Errors::DocumentNotFound
It looks like this happens because the code first tries to "find" the embedded object (which raises error) before attempting to delete it.
In this case, it would be much better to just ignore the non-existent embedded object, because it was probably already deleted. This seems to happen a lot in parts of the app where many users might be trying to modify the same object.
