Say I create a form that reflects the current state of an object. The user can edit that form, and when they click 'save', I get back the new, possibly edited, values via the POST. In my POST code I do something like this:
postDict = request.POST.copy() bookForm = BookForm(postDict, instance=bookObj) if bookForm.is_valid() bookForm.save() What do folks typically do to avoid saving the data if nothing has been modified in the form? Is there any django functionality for doing this, or do I just write the manual check that compares the fields in the form to the fields in the existing object? I'm not only concerned with the database access. In addition to avoiding the save, I'd like to emit a message to the user that reflects what they've done, or not done. IE, "book foo updated' or "book foo unchanged". Anyway, just curious if others have encountered this.
