Ok, I think I’m following you now. The JobEditForm you’ve posted really isn’t part of this process.
If you’re just receiving an html page as the post data, my initial thought would be to just extract and validate the individual components from within the view. I wouldn’t try to wedge this extracted data into a form - I’m not sure it buys you any benefits to do that.
My initial reaction would be to create one or more validation classes to handle the data. But I can’t think of anything intrinsic to Django to facilitate this process.
