Daniel The idea of using a form becomes a problem, because to replace the standar modelform inside the admin with ModelAdmin.form i need another modelform, according to this: http://docs.djangoproject.com/en/1.2/ref/contrib/admin/#adding-custom-validation-to-the-admin. If there's any way to replace a modelform with a standar form inside the admin view, i will appreciate some ideas. When i replace the modelform with a standar form, arrise an ImproperlyConfigured bug: DataAdmin.form does not inherit from BaseModelForm at admin.py: admin.site.register(Data, DataAdmin) But anyways i take your point of create new data instances inside the for loop: def save(self, commit=True, *args, **kwargs): file = self.cleaned_data['file'] records = csv.reader(file) for line in records: form_input = super(DataInput, self).save(commit=False, *args, **kwargs) form_input.place = self.cleaned_data['place'] 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() However i still got the AttributeError: 'NoneType' object has no attribute 'save'.
