#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.

#primary_key=(value) ⇒ Object
Sets the name of the primary key column.
class Project < ActiveRecord::Base
self.primary_key = 'sysid'
end
You can also define the #primary_key method yourself:
class Project < ActiveRecord::Base
def self.primary_key
'foo_' + super
end
end
Project.primary_key # => "foo_id"
