For + instance, if you are passed in a chain of relations as follows: + + Posts.select(:name => "John").order('id DESC') + + but you want to get rid of order, then this feature allows you to do: + + Posts.select(:name => "John").order("id DESC").unscope(:order) + == Posts.select(:name => "John") + + The .unscope() function is more general than the .except() method because + .except() only works on the relation it is acting on. However, .unscope() + works for any relation in the entire relation chain. + + *John Wang* + * Postgresql timestamp with time zone (timestamptz) datatype now returns a ActiveSupport::TimeWithZone instance instead of a string |
