Django: unable repr für die Klasse ‚django.db.models.query.datetimequeryset‘ bekommen

Question

ich so einige Daten in Django zu filtern versuchen:

MyModel.objects.filter(tense="future").values_list('date_updated').datetimes('date_updateded', 'hour').annotate(updated_count=Count('name')) 

Ich verwende PyCharm für das Debuggen und PyCharm zeigt:

Django: unable to get repr for class 'django.db.models.query.datetimequeryset' 

Und ich dieses auf meiner Ansicht (Browser):

UnboundLocalError at /myview/ 
local variable 'sql' referenced before assignment 

Wie kann ich dieses Problem beheben?

(Ich versuche, basierend auf ‚angespannt‘, bekommt die Zeit innerhalb einer Stunde Pause zu filtern, und die Namen zählen, eine Ausgabe so etwas wie diese (Datum, updated_count) erwartet)

EDIT, hinzugefügt Traceback:
