I've just upgraded some code to Django 1.0 and the caching stopped working.
I have found a fix but I don't understand what's happening so if
anyone can explain, I'd be grateful.
My code used to look somthing like this (simplified for clearer reading)
cached=cache.get(key)
if cached:
list=pickle.loads(cached)
else:
list = Banks.objects()
pickled = pickle.dumps(list,pickle.HIGHEST_PROTOCOL)
cache.set(key,pickled)
pickled is of type 'str', my default encoding appears to be 'ascii'.
When I call cache.set, I get a UnicodeDecodeError.
So to fix it, I add:
cached=smart_str(cached,encoding='iso_8859_1')
before the call to pickle.loads()
and
pickled=smart_unicode(pickled,encoding='iso_8859_1')
before the call to cache.set()
So what I don't understand is, why 'iso_8859_1'? As far as I know, the
python default encoding is 'ascii' and the django DEFAULT_CHARSET is
'utf-8'. So where's this coming from?
Any pointers welcome!
