Question

我有一个ListView页面在分页方面运行良好。我还在该页面上添加了Django过滤器以进行过滤。问题是分页工作正常，但是使用Django过滤器后，分页停止工作。页面加载时paginate_by不起作用。单击分页时，下一页不起作用。

我在做什么错了？

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 %}中的

如果将filter.qs替换为'object_list'，则分页和过滤将起作用。但是，当页面最初加载时未在url中设置任何过滤器参数时，该记录将没有任何记录。

我试图弄清楚该怎么办。正在搜索......

Django分页不适用于Django过滤器
