I found it, it was my fault of course. The problem was that, in the method where I make the delete, several lines after the deletion (in a code not related with the database) I use a global variable not defined so the method fails, don't return anything and I guess some automatic db.commit is not called. If I fix the global variable line, everything works without the db.commit.
