Trying to import a class from another file but my test breaks

Question

I'm trying to use prettyconf - https://github.com/osantana/prettyconf - to use a .env file.

I created a config.py file and put it in the same folder of my script.

My config.py is this one:

from prettyconf import config


class Settings:
    ENVIRONMENT = config(
        'ENVIRONMENT',
        default='dev',
        cast=config.option({'dev': 'dev', 'int': 'int', 'prod': 'prod'}),
    )

    LOG_LEVEL = config('LOG_LEVEL', default='INFO')
 

settings = Settings()

In my script I import my config.py in this way:

from cl_uploader.config import settings

But I got this error msg:

Traceback (most recent call last):
  File "cl_uploader.py", line 7, in <module>
    from cl_uploader.config import settings
  File "/home/myfolder/Doing/folder/cl_uploader/cl_uploader.py", line 7, in <module>
    from cl_uploader.config import settings
ModuleNotFoundError: No module named 'cl_uploader.config'; 'cl_uploader' is not a package

I tried to change to a relative path like this:

from .config import settings

But I got this error:

Traceback (most recent call last):
  File "cl_uploader.py", line 7, in <module>
    from .config import settings
ImportError: attempted relative import with no known parent package

But if a let like this:

from config import settings

It works! But...

My tests starts to break and I get this msg:

____________________________ ERROR collecting tests/test_cl_uploader.py _____________________________

Hint: make sure your test modules/packages have valid Python names.

My tree folder is set this way:

Answer 1

You are already in the cl_uploader folder. Try: from config import settings.

In __init__.py add this:

import os, sys
sys.path.append(os.path.dirname(os.path.realpath(__file__)))

Then, all files in this directory will be on sys.path. Might want to change the filename to cl_config.py to avoid conflicts.
