[odb-users] Automatically persist / update relations

[Andreas Pasternak MT-Robot AG]

Hello all,

I have:

#pragma db object
struct Val {
  short id;
  string value;
};
#pragma db object
struct Cont{
  std::vector> vals_rel;
}

To persist all of Cont I have to write:

Cont c;
db.persist(c);
for(val : vals_rel)
  db.persist(val);

But I'd like that ODB checks all relations automatically and inserts /  
updates them. The background is that I get the Cont class via network  
inclusive all data referenced by pointers and the recieving client  
might not have the related database entries yet.

Best regards,

Andreas
