Hi, If you don't need the form elements themselves, as you do everything in the save method, you don't need to do anything with the form. All you need to do, is to create the visual effect, which can be done with jQuery quite easily. You could just hide the fields if you prefer them empty and create some of your own fields to display then stuff in, or just use the form fields.
I would suggest a blur trigger that check if values on the needed fields have been filled. Then all you need to to, is to make a ajax get request where you send along the values. Create a view that handles the calc and sends the data back. You could also if you prefer do the calculation in javascript. But I don't see how this should break your setup. ~Jakob On 2 Apr., 09:59, Alfonso <allanhender...@gmail.com> wrote: > Hi, > > I've got two very unremarkable models, Invoice Order that has a > foreign key to an Invoice model.
