Hi Jos�,
As the documentation says, the best alternative right now is to set a
ForeignKey from one of the models to the other, on which you should
place the ForeignKey really depends on every specific case, normaly it
should go to the one that "cannot live with the other" (hence, the
dependent one).

ForeignKey simply adds a "related_model_id" column to hold the id of the
other model and both models get the appropiate attributes/methods to
find their relatives.

Hope this helps,
Marc
