Method: ActiveRecord::AttributeMethods::PrimaryKey::ClassMethods#primary_key

Defined in:
activerecord/lib/active_record/attribute_methods/primary_key.rb

#primary_key ⇒ Object

Defines the primary key field – can be overridden in subclasses. Overwriting will negate any effect of the primary_key_prefix_type setting, though.
