redis_utils.py

About this file

This file contains the utils for using Redis. The functions included in this file pertain to storing a file's metadata, returning the stored file's metadata, obtaining the file's upload key, returning the user session ID. A file's metadata includes the file size, mime type, and hash.

Function 'redis_set_file_metadata(request_or_response_id, filepath, is_update=False)' stores a file's size, mime type, and hash.

Function 'redis_get_file_metadata(request_or_response_id, filepath, is_update=False)' returns a tuple containing a file's size (int), mime type (str) and hash (str).

Code Issues

Use of modules cPickle and pickle is associated with security implications (line 5). It is normally avoided unless used cautiously. More information can be found here.
