Hi
i get the following error when trying to set data in the cache of a django application. The error is however a python error as it involves pickling and i can reproduce it in a shell. The error i get is this: cPickle.PicklingError: Can't pickle <class 'management.views.Stats'>: attribute lookup management.views.Stats failed Stats is a class i use to hold a couple of values, a string (user) and a number (calls), that are then used in a template. These are pickable, right? The data i want to pickle is the return value of this function: def calc_stats_topcallers(): stats_all = {} # cPickle doesn't like this class class Stats(object): def __init__(self): self.calls = None self.user = None current_year = datetime.datetime.now().year archive_year = current_year - 4 years = xrange(archive_year, current_year+1) for year in years: stats_year = [] counts = {} # Initialize count dict # If we don't do this, we get a KeyError for user in User.objects.all(): counts[user]=0 # Count the times an initiator has been calling for i in Call.objects.filter(date_created__year=year): for _init in i.initiator.all(): counts[_init] += 1 # Sort the dictionary count_sorted = sorted(counts.items(), lambda x, y: cmp(x[1], y[1]), reverse=True) # Take top 30 callers for user_stat in count_sorted[0:30]: if ( user_stat[1] > 0 ): st = Stats() st.calls = user_stat[1] st.user = user_stat[0] stats_year.append(st) stats_all[year]=stats_year stats_sorted = sorted(stats_all.items(), lambda x, y: cmp(x[0], y[0]), reverse=True) return stats_sorted When i run the function and pickle the data using a python shell, i get the error. How do i solve this as i haven't got a clue. Thanks, Benedict -- http://mail.python.org/mailman/listinfo/python-list
