Howto avoid traceback in case of PermissionDenied in custom can_access_file? about django-private-storage

[acaduck]

you can avoid this by rewrite the get() method of the PrivateStorageView base view:

# copied from source code:
class PrivateStorageView(View):
    def get(self, request, *args, **kwargs):
     
        if not self.can_access_file(private_file):
            raise PermissionDenied(self.permission_denied_message) # here is the cause

in your case, you can:

from django.http import HttpResponse

class AttachmentDownloadView(PrivateStorageDetailView):
    model = ImageAttachment
    model_file_field = 'file'

    def get_object(self):
        ...

    def can_access_file(self, private_file):        
        ...

  # add this
   def get(self, request, *args, **kwargs):
      if not self.can_access_file(private_file):
           return HttpResponse('unaothorized', status=401)

rather than raise an error, we returned a 401 response
