Method: ActiveRecord::Base#initialize

Defined in:
lib/active_record/base.rb

#initialize(attributes = nil) ⇒ Base

New objects can be instantiated as either empty (pass no construction parameter) or pre-set with attributes but not yet saved (pass a hash with key names matching the associated table column names). In both instances, valid attribute keys are determined by the column names of the associated table – hence you can’t have attributes that aren’t part of the table columns.
