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 result 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).
