attributes_from_column_definition() — ActiveRecord::Base

attributes_from_column_definition()

Initializes the attributes array with keys matching the columns from the linked table and the values matching the corresponding default value of that column, so that a new instance, or one populated from a passed-in Hash, still has all the attributes that instances loaded from the database would.
