我想使用django分页。第一页可以加载产品，但最后一页没有显示。
这是我的索引视图：
def index(request):
categories = Category.objects.filter(parent_category=None)
product_list = Product.objects.filter(is_deleted=False).order_by('created_at')
paginator = Paginator(product_list, 1) # Show 25 contacts per page
page = request.GET.get("page",1)
try:
products = paginator.page(page)
except PageNotAnInteger:
products = paginator.page(1)
except EmptyPage:
products = paginator.page(1)
context = {
'products': products,
'categories': categories
}
return render(request, 'product/urunler.html', context)
这是我的模板：
<div class="blog-pagination">
<ul class="flat-pagination style1">
{% if products.has_previous %}
<li class="prev">
<a href="?page={{products.previous_page_number}}" title="">
<img src="{% static 'images/icons/left-1.png' %}" alt="">Önceki Sayfa
</a>
</li>
{% else %}
<li class="prev">
<a href="#" title="">
<img src="{% static 'images/icons/left-1.png' %}" alt="">Önceki Sayfa
</a>
</li>
{% endif %}
{% for i in products.paginator.page_range %}
{% if products.number == i %}
<li class="active">
<a href="?page={{i}}" class="waves-effect" title="">{{i}}</a>
</li>
{% else %}
<li>
<a href="?page={{i}}" class="waves-effect" title="">{{i}}</a>
</li>
{% endif %}
{% endfor %}
{% if products.has_previous %}
<li class="next">
<a href="?page={{products.next_page_number}}" title="">
Sonraki Sayfa
<img src="{% static 'images/icons/right-1.png' %}" alt="">
</a>
</li>
{% else %}
{% if products.has_next %}
<li class="next">
<a href="" title="">
Sonraki Sayfa
<img src="{% static 'images/icons/right-1.png' %}" alt="">
</a>
</li>
{% endif %}
{% endif %}
</ul>
<div class="clearfix"></div>
</div>
我的数据库中有2个产品我能够显示第一页，但最后一页未显示此处是追溯：

第一页没有任何错误，但最后一页总是出错。

您正在检查has_previous，但随后又包括next_page_number。看起来您想要包含previous_page_number：
{% if products.has_previous %}
<a href="?page={{products.previous_page_number}}" title="">Previous</a>
{% endif %}
答案 1 :(得分：0)
在for循环之后的代码中，您正在检查has_previous，并且您正在犯小错误。 for循环后的代码应为
{% if products.has_next %}
<li class="next">
<a href="?page={{products.next_page_number}}" title="">Sonraki Sayfa
<img src="{% static 'images/icons/right-1.png' %}" alt=""></a>
</li>
{% else %}
<li class="next">
<a href="" title="">Sonraki Sayfa
<img src="{% static 'images/icons/right-1.png' %}" alt=""></a>
</li>
{% endif %}

也许您也可能使用分页器进行了一些尝试，并在模板中插入了多个标签来测试其工作/样式？
如果是这样，即使您注释掉这些行，django标签仍然可以使用。
因此，如果要测试分页器，则必须完全删除其他分页器。
