This error arises when I attempt to visit the Transaction Detail page from my Transaction List page. I am using a UUID (primary=true) as the PK for the Transaction Detail page.

memberships/models.py

class Transaction(models.Model):

    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="user_transaction")

    order_id = models.CharField(max_length=36, blank=True, unique=True, default=uuid.uuid4, primary_key=True, editable=False)

    membership = models.ForeignKey(Membership, on_delete=models.SET_NULL, null=True, blank=True)

    amount = models.DecimalField(max_digits=100, decimal_places=2)

    success = models.BooleanField(default=True)

    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)





    def __str__(self):

        return self.order_id



    class Meta:

        ordering = ['-timestamp']

EDIT: I added my main urls.py and the memberships/urls.py. The transaction page is under the memberships.urls.

You need to update the slug_url_kwarg in your view. For example:

class TransactionDetailView(DetailView):

    model = Transaction

    slug_field = 'order_id'

    slug_url_kwarg = 'order_id'

    ...

Because based on this code, slug value is taken from kwargs by attribute slug_url_kwarg of the View.

Also please update the url path.

Url:

path('transaction/<uuid:order_id>/', TransactionDetailView.as_view(), name='transaction_detail'),

You've set the view's slug_field parameter to order_id, but you haven't told it where to get the value for that field; the view is still expecting the URL to give it either pk or slug, as the error says.

In fact, your order_id is the primary key, not the slug, and Django already has an alias to whatever your primary key is: pk. So you should replace that attribute with pk_url_kwarg.

class TransactionDetailView(DetailView):

    model = Transaction

    pk_url_kwarg = 'order_id'
