[odb-users] Reuse inheritance and id column names

[Артём Бодрин]

Greetings, developers 8-)

I've encountered a problem with subject, when tried to reflect odb-ready
classes onto existing database tables. Consider a small test:

reflection.h with contents:

#pragma once

#include <QUuid>

class CommonBase {
public:
    QUuid id;
    QUuid class_id;
};
#ifdef ODB_COMPILER
#pragma db object( CommonBase ) abstract
#endif

class Object : public CommonBase {
public:
    quint32 num1;
};

#ifdef ODB_COMPILER
#pragma db object( Object ) table( "object" )
#pragma db member( Object::id ) column( "id" ) id
#pragma db member( Object::class_id ) column( "class_id" )
#endif

class Extension : public CommonBase {
public:
    quint32  num2;
};

#ifdef ODB_COMPILER
#pragma db object( Extension ) table( "extension" )
#pragma db member( Extension::id ) column( "object_id" ) id
#pragma db member( Extension::class_id ) column( "object_class_id" )
#endif

processed by odb compiler:
/opt/odb-2.4.0/bin/odb -I/opt/Qt5.3.0/5.3/gcc_64/include/QtCore
-I/opt/Qt5.3.0/5.3/gcc_64/include/ -d pgsql --generate-query
--generate-schema --profile qt reflection.h

and produced a following sql file with schema:

/* This file was generated by ODB, object-relational mapping (ORM)
 * compiler for C++.
 */

DROP TABLE IF EXISTS "extension" CASCADE;

DROP TABLE IF EXISTS "object" CASCADE;

CREATE TABLE "object" (
  "object_id" UUID NOT NULL PRIMARY KEY,
  "object_class_id" UUID NULL,
  "num1" INTEGER NOT NULL);

CREATE TABLE "extension" (
  "object_id" UUID NOT NULL PRIMARY KEY,
  "object_class_id" UUID NULL,
  "num2" INTEGER NOT NULL);

everything seems fine and simple, except column names for table "objects".
I've expected "id" an "class_id" respectively as defined by pragmas...

Is this an odb-compiler bug, or i must do something else to meet my needs?

Thanks in advance, Artem.
