How to fix int() error?

Question

Django

How to fix int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method' error?

views.py

from .models import Order
from .forms import OrderCreateForm
from cart.cart import Cart
from django.shortcuts import render, get_object_or_404,redirect
from shop.models import Product

def order_create(request):
    cart = Cart(request)
    
    if request.method == 'POST':
        form = OrderCreateForm(request.POST)
        if form.is_valid():
            order = form.save(commit=False)
            order.nickname = request.user
            order.product = Product.objects.get(id=id)         
            order.save()
            for item in cart:
                Order.objects.create(
                                         product=item['product'],
                                         price=item['price'],
                                         quantity=item['quantity'])
            # очистка корзины
            cart.clear()
            return render(request, 'orders/order/created.html',
                          {'order': order})
    else:
        form = OrderCreateForm
    return render(request, 'orders/order/create.html',
                  {'cart': cart, 'form': form, })

Error in the line
order.product = Product.objects.get(id=id)
In general, this function passes the name of the authorized user and the name of the product to the checkout form. Here is the name of the product can not be conveyed.

Please tell me what am I doing wrong?

Answer 1

order_createThere are no variables named in the scope of the function , so a reference to the built-in function idid is passed as an argument in the string , and the method expects a number. order.product = Product.objects.get(id=id)get

Answer 2

Please tell me what am I doing wrong?

you do not show us a normal traceback, so that you could understand something about the error. Well, I would also translate the text of the error, what to understand what it is about.
