Django百日草博客錯誤條目

Question

我正在修復百日草博客應用程序的問題，並彈出與聚合器和條目相關的錯誤。以下是代碼，如果有人有一個建議：

def get_authors(context, template='zinnia/tags/authors.html'): 
    """ 
    Return the published authors. 
    """ 

    return {'template': template, 
      'authors': Author.published.all().annotate(
       count_entries_published=Count('entries')), 
      'context_author': context.get('author')} 

在上面，我不認爲造成任何問題，但下面是可能會引起大驚小怪的倒數第二行的代碼。

def get_queryset(self): 
     """ 
     Return a queryset containing published entries. 
     """ 
     now = timezone.now() 
     return super(
      EntryRelatedPublishedManager, self).get_queryset().filter(
      models.Q(entries__start_publication__lte=now) | 
      models.Q(entries__start_publication=None), 
      models.Q(entries__end_publication__gt=now) | 
      models.Q(entries__end_publication=None), 
      entries__status=PUBLISHED, 
      entries__sites=Site.objects.get_current() 
      ).distinct() 

請提出一個解決方案，因爲整體百日草是一個了不起的應用程序，但有一個錯誤的幾乎無用。回購所有者已經得到了大量的用戶抱怨。 Python2和PYthon3的錯誤都是一樣的。

對於願意爲此工作的慷慨編碼人員，回購協議位於https://github.com/Fantomas42/django-blog-zinnia/issues。

Answer 1

嘗試在zinnia之後的INSTALLED_APPS設置中註冊django_comments之前。

INSTALLED_APPS = (
    'django.contrib.auth', 
    'django.contrib.admin', 
    'django.contrib.sites', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'django.contrib.contenttypes', 
    'mptt', 
    'tagging', 
    'zinnia', 
    'django_comments', 
)
