FileNotFoundError: [Errno 2] ? - JohnnyCoffee - Sep-22-2019

Hi,

I have the following code in a class that works perfectly fine when inside it. Now when accessing through another class file presents me with error. Below I demonstrate the class that works:

import os 
class WspApplication:

ws_listdir = os.listdir('../application/controllers')

This class works when I print inside it.
It only presents the error below when I try to access it in another class:
ws_listdir = os.listdir('../application/controllers') FileNotFoundError: [Errno 2] No such file or directory: '../application/controllers'

Below is the other class:

from syscore.wsp_application import WspApplication
class WspProtected:

def wsm_dir(ws_path):
   ws_root = WspApplication.ws_listdir
   if ws_path == ws_root:
       return 'Info. . .'.encode('utf-8')

Can disregard the path parameter in the analysis it works!
Obs: These classes are in the same directories, without permissions and using python 3.7.3

There must be some issue with ..

Try this

try:
    ws_listdir = os.listdir('../application/controllers')
except FileNotFoundError as exc
    from pathlib import Path
    raise RuntimeError(Path('..').resolve()) from exc

Ok, I forgot a colon at the end of the except... line, sorry

This is not an answer. What happened? What was the whole error traceback? One cannot debug without a return from the interpreter.

Have a comment on the code above to know what you did ?

I raised a new exception to know how python interpretes the .. directory at the moment the error occurs.

This was the error generated :

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

So you're trying to access /home/assistant/PycharmProjects/application/controllers Does this directory exist? Is it really what you want to do?
