Maurice, please remember not everyone on this ML knows finance and noone knows your application but you. Moreover, people on ML cannot spend hours trying to figure out what is your problem: sometimes just solving the problem needs a lot of work, so make things easy.
You posted your models, but I think you are implementing some views or at least using them in some code. Can you give some details about the procedure you are implementing and the exact issue tou are facing?
