NAME

DBIx::Class::PK - Primary Key class

SYNOPSIS

DESCRIPTION

This class contains methods for handling primary keys and methods depending on them.

METHODS

id

Returns the primary key(s) for a row. Can't be called as a class method.

ID

Returns a unique id string identifying a row object by primary key. Used by DBIx::Class::CDBICompat::LiveObjectIndex and DBIx::Class::ObjectCache.
WARNING
The default "_create_ID" method used by this function orders the returned values by the alphabetical order of the primary column names, unlike the ``id'' method, which follows the same order in which columns were fed to ``set_primary_key'' in DBIx::Class::ResultSource.

ident_condition

   my $cond = $result_source->ident_condition();
 
   my $cond = $result_source->ident_condition('alias');
 
 

Produces a condition hash to locate a row based on the primary key(s).
