Shame on me!
I forgot to make some changes inside the for loop.
So now it is:

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:
form_input.time = datetime.strptime(line[1], "%m/%d/%y %H:
%M:
%S")
form_input.data_1 = line[2]
form_input.data_2 = line[3]
form_input.data_3 = line[4]
form_input.save()

Buuuuut, i've got a new error message! an attribute error: 'NoneType'
object has no attribute 'save'.
What can it be?
