Example Code

from fastapi import Response, status, HTTPException, Depends, APIRouter
from sqlalchemy.orm.session import Session

from app import models, schemas
from app.database import  get_db

Description

I cant access top level module from submodule

this is my structure

├─ app
├─main.py
├─ models.py
├─ schemas.py
|───router
│    ├─── __init__.py
│    ├─── post.py
│    └─── user.py

I want to access models and schemas for my post and user in router
but I cant import all module from app
I using relative and absolute import and yet python cant find all that

I believe import using the correct way as I following tutorial on official doc and reproduce the same structure from this https://github.com/tiangolo/full-stack-fastapi-postgresql

Hi there, from what I've been researching seems that python3 doesn't allow to directly import as you have. Instead you might want to use the sys module or environment variables (which I believe is the best option) to optimize your imports.

Then you can use the import method as usual.

Try this and let me know if this works:

import sys

#Set the path to where the modules you're importing.
sys.path.insert(0, 'path to your App directory')

#Here fastApi imports.

from app import models, schemas
from app.database import get_db

try to check PYTHONPATH to be sure it's correct

where I put those sys import ?? in main file or I must that on before init file ?

I already did that

Yes is must be windows problem (windows sucks) because I dnt see it in anybody code

Could be even in the init file. However, I’d say it’s best practice to have it in the scripts where you need them.

Try if it works in any file from your router dir.

Yeah its works, iam using this

import sys
import os
sys.path.append(os.path.dirname(os.getcwd()))

Iam tried to pip install -e . and make my project to the ediable state but I cant find the import

apreciate it

Something that you can also try is setting the path as an environment variable and accessing it using the OS library.
