Method: Preferences::InstanceMethods#preferences

Defined in:

#preferences(group = nil) ⇒ Object

Finds all preferences, including defaults, for the current record. If looking up custom group preferences, then this will include all default preferences within that particular group as well.

Examples

A user with no stored values:

user = User.find(:first)
user.preferences
=> {"language"=>"English", "color"=>nil}

A user with stored values for a particular group:

user.preferred_color = 'red', :cars
user.preferences(:cars)
=> {"language=>"English", "color"=>"red"}
