我正在尝试根据prince范围筛选项目，然后对结果进行分页。我已经看了文件，但还是没用。我已经尝试了我能想出的所有逻辑，但仍然没有奏效。
搜索会显示第一页的项目，但一旦我点击后续页面，它就不会显示任何内容。如果我使用if request.Method==''POST:"，它显示：variable used before assignment。
我也尝试过使用if request.method =="GET"，但它仍然不起作用。搜索会显示第一页的项目，但一旦我点击后续页面，它就不会显示任何内容。

# urls.py
path('property_search/' ,views.availableProperty,name='property_search')
对我来说，一个快速的解决方案是使用javascript而不是django/python，因为我使用的是：
<a class="page-link" data-href="?page={{items.paginator.num_pages}}" href="?page={{items.paginator.num_pages}}">Last</a>
我添加了一个javascript来检测是否有过滤器，并添加&page＝"；页码"；而不是page＝"；页码"；。
<script>
// pagination
let pag = document.querySelectorAll('a.page-link')
console.log(pag.length)
let url = window.location
if (url.href.includes("?csrfmiddlewaretoken"))
{
for (let i = 0; i < pag.length; i++)
{
pag[i].href = url.search + pag[i].getAttribute("data-href").replace("?","&")
console.log(pag[i].getAttribute("data-href"))
}
} else {
console.log("not included")
}
</script>
希望能有所帮助。
