Django Routing w/ subApplication

Question

What I have:

• a Django Project that is acting as a REST API through Django Rest Framework.
• a number of Django Apps that are controlling the logic of my Postgres DB.

What I am trying to do:

• Create a new Django App that represents a Service / Integration with Robinhood
• Within ^^ I want to structure my logic in subApplications in order to separate all logic for a user vs a transactions vs a transfers etc ...
• This entire Django App & all subApplications are APIs ONLY ... they will never need models / migrations but they will eventually communicate with the other Django Apps

SERVICE_robinhood/urls.py

# ?? do I need to import user here and pass it differently into `include` ??
# I thought that since `users` should be a module in and of itself in the overall Django Project you could just reference the app by name

urlpatterns = [
    ❌ path('user/', include('user.urls')),
    ✅ UPDATE - FROM ANSWER: ✅ path('user/', include('SERVICE_robinhood.user.urls')),

SERVICE_robinhood/user/urls.py

from . import utils
urlpatterns = [
    path('printSomething/', utils.printSomething, name='printSomething')
]

Error I am getting:

SERVICE_robinhood/urls.py", line 23
...
ModuleNotFoundError: No module named 'user'

I am assuming that this is an issue with how I am importing the sub application into the overall app but have added all the relevant code I can think of to uncover any other problems.

Answer 1

Per Amine's answer (ProfileLink) do the following in your Django App to import a subApplications routes:

SERVICE_robinhood.urls.py

urlpatterns = [
    path('user/', include('SERVICE_robinhood.user.urls')),
]
