Method: ModelRecord#update

Defined in:
lib/model/the_record.rb

#update(set: {}, add: nil, to: nil, **args) ⇒ Object

Convient update of the dataset by calling sql-patch

Previously changed attributes are saved to the database.

Using the optional :set argument ad-hoc attributes can be defined

obj = ActiveOrient::Model::Contracts.first
obj.name =  'new_name'
obj.update set: { yesterdays_event: 35 }

updates both, the »name« and the »yesterdays_event«-properties

note: The keyword »set« is optional, thus

obj.update  yesterdays_event: 35

is identical
