Exception Type: ValueError at /blog/archive/ 
Exception Value: Database returned an invalid datetime value. Are time zone definitions for your database and pytz installed? 

私は "MySQL mysql_tzinfo_to_sql program" にしようと試みた今、私はこれらのエラーを取得しています。しかし、それはうまくいかない。

解決策は何ですか？

from django.views.generic.list import ListView
 

from django.utils import timezone
 

...
 

class NewsListView(ListView, ArchiveIndexView, CategoryListMixin):
 

model = New
 

...
 

def get_context_data(self, **kwargs):
 

context = super(NewsListView, self).get_context_data(**kwargs) 

    context['now'] = timezone.now() 

    return context
