update(id, attributes)
public
Updates an object (or multiple objects) and saves it to the database, if validations pass. The resulting object is returned whether the object was saved successfully to the database or not.

- attributes - This should be a hash of attributes to be set on the object, or an array of hashes.
Examples
# Updating one record: Person.update(15, :user_name => 'Samuel', :group => 'expert') # Updating multiple records: people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy" } } Person.update(people.keys, people.values)
