Re: django model forms validation and error display

I recommend using Class Based Views if you're running Django 1.3. I tried to go over your app and re-create a prototype using CBVs. I didn't spend a lot of time on the actual logic or field types. I also didn't even try running this. You'll need to fill in a couple of blanks but hopefully you get the idea. I hope it helps :)

i have this template: http://dpaste.com/645468/ that send data to this
view: http://dpaste.com/645469/. the template display a form made by
modelforms, with a custom layout. i have to validate the fields value
send to view, and then redirect to the same template if the field
validation fails. i've tried to do it by creating an instance of the
related model, then gathering all fields one by one (checking before
if they are present in request.POST) and assigning it to the model
field, and then assigning that model instance to a new modelform
instance. then i've prefromed a .is_valid() check, but it fails since
it require the model instance pc, so that model instance need to exist
on db. so how can i validate those data, and if validation fails,
redirect to another template and display the errors?
