so I am using the code from the Django documentation to processes
information from a form with the code :
def edit_place(request, place_id):
try:
manipulator = Place.ChangeManipulator(place_id)
place = manipulator.original_object
if request.method == 'POST':
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
manipulator.do_html2python(new_data)
if not errors:
manipulator.save(new_data)
return HttpResponseRedirect("/places/edit/%i/" % place.id)
else:
errors = {}
new_data = manipulator.flatten_data()
form = forms.FormWrapper(manipulator, new_data, errors)
return render_to_response('places/edit_form.html', {'form': form,
'place': place})
However in my post data from my form I don't return data for all the
values in my model. This is because I don't want the user to be able
to change some of these, only to see them. I am not sure how to fill
the new_data dict with the old values (ones not being returned from
the form in the post method) when saving to the db.
I have tried using a value old_data=manipulator.flatten_data() and
making a comparison and but have got a error
argument of type 'long' is not iterable
Help?
