Re: PermissionError with open()

Your call to 

".format(file_name)"

does nothing as the original string does not have the positional arguments ("{0}" for example)

You could just append the filename with "+".

Hello everyone,

I am trying to run this code inside view.py, to make PDF file able to be downloaded :

import os  BASE_DIR = os.path.dirname(os.path.dirname(__file__))      def download(request, file_name = 'article1'):          file = open(os.path.join(BASE_DIR, 'media').replace('\\','/').format(file_name), 'rb')          response = HttpResponse(file, content_type='application/pdf')          response['Content-Disposition'] = "attachment; filename={}".format(file_name)          return response

The problem with line 4. I will get PermissionError on windows

PermissionError at /download/    [Errno 13] Permission denied: 'C:/Users/Oana/Desktop/tutela-net/media'

 

and IsADirectoryError on linux.

Even though, if I will use 'wb' instead of 'rb' or any other options. or the absolute path, I will get the same error.
