Go to your app directory " ...\\myNewproject\\PMSdate\\PMSDetails_data\\urls.py,
check if you have added your :
from django.urls import path
app_name = "PMSDetails_data"
urlpatterns = [
path('your_url/', views.function, name="url_name"),
]
You have not included a "urls.py" file in your app directory... sorry i am just seeing this.
