I am working on an application which is in Django. I am trying to store some data structure e.g. dictionary in MySQL db. So i use Python Pickle module. It works fine when i store it in db using pickle.dumps(some_structure). My DB field is longblob mode is binary.

But when i access the field of model object in django:

obj = someModel.get(pk=1)
some_structure = obj.field
content  = pickle.loads(some_structure)

it raises following error:

UnpicklingError: invalid load key, '{'.

Please help me, i have tried google but it does'nt help me, also there is one similar Question but it is not related to my problem as i am storing in db.
