Can i save a file object <input type="file" name="file"> to CoreSessionTracking? I have a :records which I convert to a list of dictionaries. The net result is: [{'description':'Elvis','file':<file instance>},{'description':'Madonna','file':<file instance>},...] When I try to save this to CST, I get Unpickleable Error: cannot pickle objects. -- Milos Prudek
