DBIx::Class::PK(3)                   User Contributed Perl Documentation                  DBIx::Class::PK(3)



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).
