Hang on, what you're doing here is repeatedly setting the data values
for each line to the *same* form_input model. Presumably what you
actually want to do is to create new Data instances for each line in
the CSV, with the place set to the value of the form.
In this case, I'd recommend not to bother with a ModelForm at all.
Instead, just use a standard Form, and create new Data instances in
your for loop:
class DataInput(forms.Form):
file = forms.FileField()
place = forms.ModelChoiceField(queryset=Places.objects.all())
def save(self):
records = csv.reader(self.cleaned_data[file])
for line in records:
data_obj = Data()
data_obj.time = datetime.strptime(line[1],
"%m/%d/%y %H: %M: %S")
data_obj.data_1 = line[2]
data_obj.data_2 = line[3]
data_obj.data_3 = line[4]
data_obj.save()
