Hi Jirka!

The idea behind the modelform is bring an intuitive way to the admin
of the site (a non django-developer) for doing the import of several
files. If with the ORM i can do something similar, it will be great!
There's something i can read to get into it?

Thanks Daniel!

I do some changes:

Forms.py:

def save(self, commit=True, *args, **kwargs):
form_input = super(DataInput, self).save(commit=False, *args,
**kwargs)
form_input.place = self.cleaned_data['place']
form_input.file = self.cleaned_data['file']
records = csv.reader(form_input.file)
for line in records:
self.time = datetime.strptime(line[1], "%m/%d/%y %H:%M:
%S")
self.data_1 = line[2]
self.data_2 = line[3]
self.data_3 = line[4]
form_input.save()

But i'm still get the same IntegrityError. The csv file is fine, so i
don't know why is null.

Regards!
