Thanks for helping me
from ecommerce.store.models import Product will find package ecommerce from project root dir, this will find the subdirectory ecommerce not root directory ecommerce, you can use absolute import:
from store.models import Product
or just use relative import(recommended way):
from .models import Product
try change your wrong import:
from ecommerce.models import Product
I had a similar issue, found out that I did not import the forms into views.py header file.
Check to make sure that this has been imported

I get this error when I go to try to add another Nurse. The URL is http://127.0.0.1:8000/admin/lifesaver/nurse/add/. Everything else behaves as expected, except the adding the Nurse part.
If I try to remove the def __str___ part, the error still displays. I believe the error lies in the:
work_shift = models.OneToOneField(WorkShift, default="",
blank=True,
null=True,
on_delete=models.CASCADE)
part since when I included that code, the error spawned. Furthermore, the code is to add a work shift to certain employees and the goal is that the employees shift will display in their profile.
How do I fix this issue?
EDIT: When accessing the HTML template, the web page behaves as expected and has no issues.
In your Nurse model replace this:
def __str__(self):
return str(Nurse.name)
with this:
def __str__(self):
return self.name
