Cannot Solve “ValueError: attempted relative import beyond top-level package”

Question

I am running the project and shows this error. I have googled and tried some of the solutions but doesn't seem to work.

File "/home/bs-094/Dev/backend/busgroup-backend/src/bus_portal_backend/apps/inquiry/forms/inquiry_details.py", line 2, in <module>
    from ..models.inquiry import Inquiry
ValueError: attempted relative import beyond top-level package

My folder structure is

busgroup-backend
 src
  bus_portal_backend
   apps
    inquiry
      models
       _init_.py
       inquiry.py
      forms
       inquiry_details.py

It would be great help is anyone helps me solve the problem. I am fairly new to django. Thanks

EDIT : Here's what solved my problem , I had to import in this way

from bus_portal_backend.apps.inquiry.models import Inquiry

Also, I was running with debugger. My script path was busgroup-backend/src/manage.py , I changed it to /home/bs-094/Dev/backend/busgroup-backend/src/manage.py , which made me run the project successfully.

Answer 1

forms does not appear to contain an __init__.py file, and so Python doesn't think it's a package. Therefore an attempt to import from ..models is an attempt to ascend above the current package's root (because ...busgroup-backend/src/bus_portal_backend/apps/inquiry/forms/inquiry_details.py is actually a standalone module).

Relative imports only work within a package. Therefore you should make both forms and models subpackages of inquiry by creating inquiry__init__.py as well.

Answer 2

If you import from ..models.inquiry import Inquiry then .. refers to

busgroup-backend
 src
  bus_portal_backend
   apps

Which does not have an __init__.py and thusly is not considered a package by python.
