Problem with get_absolute_url()

This code in the chemical model indicates that I'm trying to display two
different views of the same chemical which has certain data in a details
1:1 record


class Chemical(models.Model):
    ...
    def get_absolute_url(self):
        detail = self.get_detail()
        if detail and detail.report_type == INTRO:
           return f"/report/intro/{self.id}/"
        return f"/report/audit/{self.id}/"




But it doesn't matter what report_type is selected, the same report
displays. Print statements inserted indicate the correct report_type
branch is being executed and the correct url is being returned.

The url which displays the report is always the first of whichever of
the following patterns is above the other ...



from django.urls import re_path
from report import views as report_views

app_name = "report"

urlpatterns = [
    re_path(r"(?P<pk>\d+)/$",
        report_views.audit,
        name="audit",
    ),
    re_path(r"(?P<pk>\d+)/$",
        report_views.intro,
        name="intro",
    ),
]




Both reports are identifiably different. In the above configuration the
audit report always shows no matter which report_type is selected.

Where am I going wrong?

I have tried to get reverse() working by following along with ...

https://docs.djangoproject.com/en/2.2/ref/models/instances/#get-absolute-url

... but to no avail. I think if I can get it working with specified urls
I should be able to get reverse working.

Thanks for any hints

Cheers

Mike
