我正在尝试修复Zinnia博客应用程序的问题及其与聚合器和条目相关的弹出错误。以下是有人提出建议的代码：
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')}
上面我不认为导致任何问题，但下面是可能导致倒数第二行所有麻烦的代码。
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()
请建议一个解决方案，因为整体百日草是一个令人印象深刻的应用程序，但有一个错误，它几乎无用。回购的所有者已经有很多用户抱怨。 Python2和PYthon3的错误都是一样的。
对于愿意为此工作的慷慨的程序员，回购位于https://github.com/Fantomas42/django-blog-zinnia/issues。

答案 0 :(得分：2)
尝试在之前的INSTALLED_APPS设置中注册zinnia之后的django_comments。
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',
)
从repo的所有者那里得到了这个解决方案。检查Github上的问题。
