Hi, I am using GAE (dev server) and i am unable to cache Row objects. For some reason they cannot be pickled. When a convert it to dicts everything works fine, but then i am unable to work with web2py Rows.
This is a related post: https://groups.google.com/forum/#!msg/web2py/SbJGKMRyeT8/BNybB-znFQgJ I tried 2 different ways and below i copied the errors. The first is when using my own caching mechanism in which i pickle the data myself and directly use GAE memcache. The second is when i use "@cache.action" * * *Pickle by me* ========= Traceback (most recent call last): File "C:\Users\****************\gluon\restricted.py", line 212, in restricted exec ccode in environment File "C:\Users\****************\applications\init\controllers/api.py", line 401, in <module> File "C:\Users\****************\gluon\globals.py", line 194, in <lambda> self._caller = lambda f: f() File "C:\Users\****************\gluon\globals.py", line 158, in f return rest_action(*_self.args, **_self.vars) File "C:\Users\****************\applications\init\controllers/api.py", line 346, in GET return get(get_articles, use_etag, t, categories=c, channel=ch) File "C:\Users\****************\applications\init\controllers/api.py", line 259, in get cached_response = pickle.dumps(cached_response) File "C:\Python\Python273_X86\Lib\pickle.py", line 1374, in dumps Pickler(file, protocol).dump(obj) File "C:\Python\Python273_X86\Lib\pickle.py", line 224, in dump self.save(obj) File "C:\Python\Python273_X86\Lib\pickle.py", line 331, in save self.save_reduce(obj=obj, *rv) File "C:\Python\Python273_X86\Lib\pickle.py", line 401, in save_reduce save(args) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 562, in save_tuple save(element) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 649, in save_dict self._batch_setitems(obj.iteritems()) File "C:\Python\Python273_X86\Lib\pickle.py", line 663, in _batch_setitems save(v) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 649, in save_dict self._batch_setitems(obj.iteritems()) File "C:\Python\Python273_X86\Lib\pickle.py", line 663, in _batch_setitems save(v) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 600, in save_list self._batch_appends(iter(obj)) File "C:\Python\Python273_X86\Lib\pickle.py", line 615, in _batch_appends save(x) File "C:\Python\Python273_X86\Lib\pickle.py", line 331, in save self.save_reduce(obj=obj, *rv) File "C:\Python\Python273_X86\Lib\pickle.py", line 419, in save_reduce save(state) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 649, in save_dict self._batch_setitems(obj.iteritems()) File "C:\Python\Python273_X86\Lib\pickle.py", line 663, in _batch_setitems save(v) File "C:\Python\Python273_X86\Lib\pickle.py", line 331, in save self.save_reduce(obj=obj, *rv) File "C:\Python\Python273_X86\Lib\pickle.py", line 401, in save_reduce save(args) File "C:\Python\Python273_X86\Lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python\Python273_X86\Lib\pickle.py", line 562, in save_tuple save(element) File "C:\Python\Python273_X86\Lib\pickle.py", line 300, in save self.save_global(obj) File "C:\Python\Python273_X86\Lib\pickle.py", line 748, in save_global (obj, module, name)) PicklingError: Can't pickle <class 'gluon.dal.article'>: it's not found as gluon.dal.article *@cache.action* =========== Traceback (most recent call last): File "C:\Users\****************\gluon\restricted.py", line 212, in restricted exec ccode in environment File "C:\Users\****************\applications\init\controllers/api.py", line 403, in <module> File "C:\Users\****************\gluon\globals.py", line 194, in <lambda> self._caller = lambda f: f() File "C:\Users\****************\gluon\cache.py", line 505, in wrapped_f rtn = cache_model(cache_key, lambda : func(), time_expire=time_expire) File "C:\Users\****************\gluon\contrib\gae_memcache.py", line 40, in __call__ self.client.set(key, (time.time(), value)) File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\memcache\__init__.py", line 773, in set namespace=namespace) File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\memcache\__init__.py", line 878, in _set_with_policy time, '', namespace) File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\memcache\__init__.py", line 957, in _set_multi_async_with_policy stored_value, flags = _validate_encode_value(value, self._do_pickle) File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\memcache\__init__.py", line 227, in _validate_encode_value stored_value = do_pickle(value) File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\memcache\__init__.py", line 399, in _do_pickle pickler.dump(value) TypeError: 'NoneType' object is not callable Does anyone know whats going on here?
