Failed using with_map_records twice

[Olivier Salaün]

Hi,

I use Rose-DB-Object version 0.795.

I have a strange behavior using the 'with_map_records' Rose::DB::Object::Manager option.

The objects I'm working with :

• FederationRegistry::Data::Federation class
  
• FederationRegistry::Data::Serviceprovider and FederationRegistry::Data::Identityprovider classes with many2many relation with FederationRegistry::Data::Federation

I need to access the mapping table because it contains usefull DB field.

I can run this code to browse identityproviders and their relations with federations:

   $idps = FederationRegistry::Data::Identityprovider::Manager->get_identityproviders(
    with_objects => ['federations'],
    with_map_records => 1,
    );
   
    foreach my $provider (@$idps) {
      foreach my $federation (@{$provider->federations}) {   
        printf "%s / %s / %s / %s\n", $provider->entityid, $federation->map_record()->status;
      }
    }

But if I try running the code below to browse serviceproviders afterward, it fails with this error message: "next() - Illegal map record argument: FederationRegistry::Data::ServiceproviderFederationMap=HASH(0xa4dddb4) at /usr/lib/perl5/site_perl/5.8.8/Rose/DB/Object/Manager.pm line 2284"

The second part of the code:

   $sps = FederationRegistry::Data::Serviceprovider::Manager->get_serviceproviders(
    with_objects => ['federations'],
    with_map_records => 1,
    );
   
    foreach my $provider (@$sps) {
      foreach my $federation (@{$provider->federations}) {   
        printf "%s / %s / %s / %s\n", $provider->entityid, $federation->map_record()->status;
      }
    }

I can run each of these pieces of code alone, but not within the same script.
Removing "with_map_records => 1," for the FederationRegistry::Data::Serviceprovider::Manager->get_serviceproviders() call removes the error, but then I can't access DB fileds of the mapping table.

Is there anything I do wrong?

Thanks for your help.

Try giving each map record method a different name (since they will
end up holding objects of different types). E.g., with_map_records =>
'some_method_name' instead of with_map_records => 1

Hi John,

It works much better when each call to Rose::DB::Object::Manager defines
a different method name associated to with_map_records.
Thanks a lot very the very quick response :)
