django - File not found on pythonanywhere.com

Question

On pythonanywhere.com I have a django app. This is views.py:

def literature(request):
    module_dir = os.path.dirname(__file__)
    file_path = os.path.join(module_dir, 'literature.csv')
    with open(file_path, 'r') as f:
        ...

File literature.csv is located at the same directory as views.py. But every time when I try to load the page I get FileNotFoundError. The same construction works normally on local server. Where is the bug?

Answer 1

This os.path.dirname(__file__) is giving you a relative path. On your local server, it just happens that it corresponds to the correct path. On PythonAnywhere, use the full path for module_dir. Like this: os.path.abspath(os.path.dirname(__file__))
