Have tried model.__dict__ and model_to_dict. In both cases it often returns values as objects instead of string values. For instance, a date comes back as a list, so does a text field. Then I'll receive an error like this:
Environment: Request Method: POST Request URL: http://127.0.0.1:8000/edit_pet/8/ Django Version: 1.0.2 final Python Version: 2.5.4 Traceback: File "C:\Python25\lib\site-packages\django\core\handlers\base.py" in get_response 86. response = callback(request, *callback_args, **callback_kwargs) File "C:\Python25\lib\site-packages\django\contrib\auth\decorators.py" in __call__ 67. return self.view_func(request, *args, **kwargs) File "C:\Python25\lib\site-packages\PetSite\apps\pets\views.py" in userEditPet 322. if form.is_valid(): File "C:\Python25\lib\site-packages\django\forms\forms.py" in is_valid 120. return self.is_bound and not bool(self.errors) File "C:\Python25\lib\site-packages\django\forms\forms.py" in _get_errors 111. self.full_clean() File "C:\Python25\lib\site-packages\django\forms\forms.py" in full_clean 231. value = field.clean(value) File "C:\Python25\lib\site-packages\django\forms\fields.py" in clean 308. return datetime.date(*time.strptime(value, format)[:3]) File "C:\Python25\lib\_strptime.py" in strptime 327. found = format_regex.match(data_string) Exception Type: TypeError at /edit_pet/8/ Exception Value: expected string or buffer I did find this ticket http://code.djangoproject.com/ticket/5126 which I'm going to have a read through in more detail later today. My code goes like this values = model_to_dict(instance) values.update(request.POST) It then fails on form.is_valid() because it's trying to match a date string in a date value that is actually a list with one value in it instead of a date string!
