Define "problems". It did nothing? It raised an exception? Your computer caught on fire? It will use understand what the underlying issue is. One thing that does jump out is you'll almost certainly need to handle the oa == self case, since that will infinitely loop, by the looks of it (once you fix the various syntax errors in the above). > I then figured it may run into a loop of saving the same model, so i > was going to use signals but ran into the same issue that it would > still need to be in the save function.
