In master class

    NUT_DECLARE_CHILD_TABLE(Score, scores)

Post::Post(QObject *parent) : Table(parent),
    m_id(0), m_title(""),
    m_scores(new TableSet<Score>(this))
{

}

NUT_IMPLEMENT_CHILD_TABLE(Post, Score, scores)

The macro NUT_IMPLEMENT_CHILD_TABLE will be put codes of child class implement

    NUT_FOREIGN_KEY_DECLARE(Post,        int,         post,    post,            setPost)

In source:

    NUT_FOREIGN_KEY_IMPLEMENT(Score, Post, int, post, post, setPost)
