Looping insert data to database with django

Question

can insert loop data into django model?..

here my code. on view.py


    class EmpCreateView(CreateView):
        fields = ()
        model = models.Employee

        def form_valid(self, form):
            self.object = form.save(commit=False)

            loopdo = 5
            while loopdo > 0:
                self.object.name = "work?" 
                self.object.no = loopdo
                self.object.save()
                loopdo -= 1

            return super(ModelFormMixin, self).form_valid(form)

it's only insert 1 data.

Could it be that your data model doesn't allow some of the data taken from the form to be duplicated (unique = true) ? That way most of the insertions would fail since you can't have, for example, the same name twice. — Alceste_, Apr 22 '18 at 03:14
Don't use loop for save multiple objects, use bulk_create.. it is an advice only — Phd. Burak Öztürk, Apr 22 '18 at 03:14
@BurakÖztürk bulk create can use data from another model?... — Dicky Raambo, Apr 22 '18 at 03:16
I get **super(type, obj): obj must be an instance or subtype of type** — AnonymousUser, Jun 02 '22 at 05:12

You should try setting the primary key to None.

See this answer: How can I save the same form more than once in Django 1.8?

I got my reference from: Save multiple data using loops in django models using save function with admin save button

Why are we not advising a formset here? – Swift Nov 03 '22 at 23:41
