django 分页不适用于 django 过滤器

Question

我有一个ListView 页面，它与分页配合得很好。我还在该页面中添加了 Django 过滤器进行过滤。问题是分页运行良好，但使用 Django 过滤器它停止工作。当页面加载时paginate_by 不工作。单击分页时，下一页不起作用。

我做错了什么？

views.py

class JobsListView(ListView, FilterView):
# model = JobPost
queryset = JobPost.objects.all()
template_name = 'jobpost_list.html'
paginate_by = 3
# page_kwargs = 'page'
filterset_class = JobPostFilter

def get_queryset(self, *args, **kwargs):
    if self.kwargs:
        return JobPost.objects.filter(position=self.kwargs['position']).order_by('-created_at')
    else:
        query = JobPost.objects.all().order_by('-created_at')
        return query

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context['todays'] = date.today()
    context['filter'] = JobPostFilter(self.request.GET,  queryset=self.get_queryset())
    return context

Answer 1

在{% for job in filter.qs %} 中，如果您将filter.qs 替换为“object_list”，则分页和过滤将起作用。但是当页面最初加载时，在 url 中没有设置任何过滤器参数时，这不会有任何记录。

我试图弄清楚可以做什么。正在搜索中......
