分页Wagtail站点最后一页EmptyPage错误

我搜索了这个网站，没有一个答案与我尝试过的不同:Example | Example | Example | Example

我的目标是在我的Wagtail网站上显示每个分页页面5个帖子。它的工作，除了我得到一个持久的EmptyPage错误在最后一页。我目前有25个帖子，所以5个页面上应该有5个帖子。只有第5页(目前是最后一页)显示为空。

我很确定问题是与模板而不是与查询集/模型本身，但我在网上看到的一切看起来与我所拥有的完全相同。

这是我的模型:

class BlogIndexPage(Page):
body = RichTextField(blank=True)
def get_context(self, request, *args, **kwargs):
context = super().get_context(request, *args, **kwargs)
blog_pages = BlogPage.objects.live().public().order_by("-date")
page = request.GET.get("page")
paginator = Paginator(blog_pages, 5)
try:
blog_pages = paginator.page(page)
except PageNotAnInteger:
blog_pages = paginator.page(1)
except EmptyPage:
blog_pages = paginator.page(paginator.num_pages)

context["blog_pages"] = blog_pages
return context

这是我的模板:

{% if blog_pages.paginator.num_pages > 1 %}
{% if blog_pages.has_previous %}
<li class="page-item">
<a href="?page={{ blog_pages.previous_page_number }}" class="page-link">
<span>&laquo;</span>
</a>
</li>
{% endif %}

{% for page_num in blog_pages.paginator.page_range %}
<li class="page-item {% if page_num == blog_pages.number %} active{% endif %}">
<a href="?page={{ blog_pages.next_page_number }}" class="page-link">
{{ page_num }}
</a>
</li>
{% endfor %}

{% if blog_pages.has_next %}
<li class="page-item">
<a href="?page={{ blog_pages.next_page_number }}" class="page-link">
<span>&raquo;</span>
</a>
</li>
{% endif %}
{% endif %}

在这段代码中:

{% for page_num in blog_pages.paginator.page_range %}
<li class="page-item {% if page_num == blog_pages.number %} active{% endif %}">
<a href="?page={{ blog_pages.next_page_number }}" class="page-link">
{{ page_num }}
</a>
</li>
{% endfor %}

?page={{ blog_pages.next_page_number }}应为?page={{ page_num }}
