How to insert a form into a ListView?

Question

Django

I have a model

class Notif(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    date = models.DateTimeField(default=timezone.now)
    text = models.CharField(max_length=100)

And in the template, I display all the objects of the model, but the form does not work in any way. The maximum that I could achieve was that the form started to show in the template, but upon confirmation it gives a 405 error. Here is the view

class Home(ListView):
    template_name ='main.html'
    context_object_name = 'p'
    model = Notif

    def get_context_data(self, **kwargs):
        context = super(Home, self).get_context_data(**kwargs)
        context['form'] = Notif()
        return context
