Is it possible by making small change to resolve the error below:
(I did not yet finished reading all manual, maybe the error disappears
if i make custom code for every line in the model, but my model has

all these fields)

It's not very likely to encourage people to help you if you admit you haven't read the documentation.

What exactly are you trying to do here? You instantiate a form from an instance, and immediately try and save it, without even passing in values from the POST. Why? In any case, the error is that forms don't have a cleaned_data attribute until you call is_valid() on them, which the documentation does clearly state. The documentation also shows the correct pattern for using forms in views, so I don't know why you haven't used that.

(Not related to your problem, but the template path in your call to render_to_response won't work: you should pass a path that is relative to one of the paths in settings.TEMPLATE_DIRS.)
