Another issue I run into intermittently is the following:
TypeError: can't pickle function objects
Module myproject.lib.account_api:98 in get_user view
>> get(user_id)
Module sqlalchemy.orm.query:637 in get view
>> return self._get(key, ident)
Module sqlalchemy.orm.query:1968 in _get view
>> return q.one()
Module sqlalchemy.orm.query:1656 in one view
>> ret = list(self)
Module myproject.model.caching:75 in __iter__ view
>> return self.get_value(createfunc=lambda: list(Query.__iter__(self)))
Module myproject.model.caching:93 in get_value view
>> ret = cache.get_value(cache_key, createfunc=createfunc)
Module beaker.cache:214 in get view
>> return self._get_value(key, **kw).get_value()
Module beaker.container:299 in get_value view
>> self.set_value(v)
Module beaker.container:332 in set_value view
>> self.namespace.set_value(self.key, (storedtime, self.expire_argument,
>> value))
Module beaker.ext.memcached:67 in set_value view
>> self.mc.set(self._format_key(key), value)
Module memcache:515 in set view
>> return self._set("set", key, val, time, min_compress_len)
Module memcache:725 in _set view
>> store_info = self._val_to_store_info(val, min_compress_len)
Module memcache:697 in _val_to_store_info view
>> pickler.dump(val)
Module copy_reg:70 in _reduce_ex view
>> raise TypeError, "can't pickle %s objects" % base.__name__
