My view object 'has no attribute' {my attribute} in Django - django

Question

Background
I'm trying to load a custom url (e.g. www.mysite.com/order-2523432) that will show a user details about their order.
Problem
I am trying to use the method order_id in my models.py in order to get the correct url. The problem is that I am getting the error:
'OrderDetailView' object has no attribute 'order_id'
Does anyone know what I can do to get order_id to work?
My views.py:
class OrderDetailView(DetailView):
model = Orders
template_name = "customer/orders.html"
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
try:
context["orders"] = get_orders(self)
except RequestException as e:
logger.exception(e)
return context
My utils.py:
def get_orders(orders):
url = f"mysite.com/customer/{orders.order_id}"
method = "GET"
content_type = "application/json"
header = Sender(
credentials etc
).request_header
response = requests.request(
headers etc
)
response.raise_for_status()
return response.json()
My models.py:
class Orders(CustomModel):
table_name = models.CharField(max_length=256, unique=True)
#property
def order_id(self):
return f"order-{self.table_name}"
def get_absolute_url(self):
return reverse("order:edit", args=(self.id,))

Answer 1

you should use self.object or context['object'] or get_object() instead of passing self
please try this:
class OrderDetailView(DetailView):
model = Orders
template_name = "customer/orders.html"
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
try:
context["orders"] = get_orders(context['object'])
except RequestException as e:
logger.exception(e)
return context
