ModuleNotFoundError: No module named 'C:\\repos\\<API_NAME>\\app' #33

Closed djkemmet closed 1 year ago

djkemmet commented 1 year ago

Describe the bug Panther suddenly throws ModuleNotFoundError in the middle of development. Project structure hasn't changed only contents per the documentation and my idea and my IDE reports no errors with the project.

Expected behavior I expect the app module to be found

Desktop (please complete the following information):

Additional context I have tested on windows, linux, vs code, pycharm, vnev and out and basically when I start making substantive changes to the API project the app module suddenly become unfind-able:

main.py

from panther.app import API
from panther.request import Request
from panther.response import Response
from panther import status

from serializers import MFA_Exception_Request_Serializer

@API(input_model=MFA_Exception_Request_Serializer)
async def MfaExceptionsEndpoint(request: Request):

    data: MFA_Exception_Request_Serializer = request.data

    if request.method == 'POST':
        message = f"You have POSTED to MFA Exceptions for device {data.hostname}"
        return Response(data=message, status_code=status.HTTP_200_OK)

    return Response(data="None of that.", status_code=status.HTTP_501_NOT_IMPLEMENTED)

urls.py

from apis import MfaExceptionsEndpoint

urls = {
    'mfa/requested-exceptions/': MfaExceptionsEndpoint,
}

serializers.py

from pydantic import BaseModel

class MFA_Exception_Request_Serializer(BaseModel):
    hostname: str

main.py

from panther import Panther

app = Panther(__name__)

IDE Error

The error seems to come from main.py which literally hasn't even been touched.

AliRn76 commented 1 year ago

Are you sure this error happened in Linux too?

As I understand from this log, we had a problem with collecting models in Windows but it was fixed in v2.1.2, Please upgrade your Panther to the latest (2.4.0) version and see if this error still happens!

Same Issue on windows - going to focus on windows troubleshooting since that's what my organization will require me to use

The contents of my files remain the same and my idea indicates no errors in the code. I recreated the project fresh with panther 4.2.0 and then copy and pasted the contents from the opening issue into my various files.

Ok, then, thank you for the issue, I'm going to track this issue in Windows ASAP 👍

AliRn76 commented 1 year ago

Fixed in 2.4.1, Please upgrade your Panther version again.
