I am creating a web application for a pizzeria. You need to add an action: when you click on the "Order delivered" button, the order status should change to "Order completed". How to do it? It is necessary that when you click on the button, the status field in the order changes

You have to make a post request to your OrderView. For example,
class OrderView(ListView):
model = OrderPizzaWithPrice
template_name = 'mainapp/listOrder.html'
context_object_name = "orders_list"
ordering = ['-id']
def post(self,request):
order = get_object_or_404(OrderPizza, id=request.POST.get('order_id'))
order.status = "Order completed"
order.save()
context = self.get_context_data()
return render(request, template_name, context)
In your listOrder.html:
<form method="post" action="order_view_url">
<input type="hidden" name="order_id" value="{{i.order.order.id}}"/>
<button type="submit">Заказ доставлен</button>
</form>
