Foreign key properties

[e.lema...@physioflow.com]

When adding a "fk" property which has a pointer type to a QObject registered with QDjango, it automatically adds 2 properties to the object : "fk_id" which I totally understand, and "fk_ptr" which confuses me.

Aren't "fk" and "fk_ptr" the same thing ? Why use "fk_ptr" instead of directly using "fk"?

Thanks !
