Question

我正在使用Django-filter对列表视图查询集进行过滤和排序。

当前统计信息-用户提交过滤器时，页面会刷新并显示新查询。

我的目标-在无需刷新页面的情况下获取列表更新+在每个过滤器选择中都进行列表更新（而不是等待用户选择所有所需的过滤器并提交）

我相信该解决方案将包括Ajax，但是我不确定如何通过Django过滤器来使用它，不幸的是，文档中没有任何提及。

Filter.py

class FestivalFilter(django_filters.FilterSet):
    style = django_filters.MultipleChoiceFilter(choices=Festival.style_choices,widget=forms.CheckboxSelectMultiple,)
    camp_style = django_filters.MultipleChoiceFilter(choices=Festival.camp_style_choices,widget=forms.CheckboxSelectMultiple,)
    friendly = django_filters.BooleanFilter(method='avg_above3',)
    .....
    def avg_above3(self, queryset, name, value):
        return queryset.annotate(avg=Avg('Festival_Reviews__{}'.format(name))).filter(avg__gt=3)

views.py

from django.views.generic import (TemplateView, ListView)
from festival_list import models
from django.views import generic
from .filter import FestivalFilter
from .filter_mixin import ListFilteredMixin
from el_pagination.views import AjaxListView
from django.contrib.auth.mixins import (LoginRequiredMixin, 
PermissionRequiredMixin, UserPassesTestMixin)
from braces.views import SelectRelatedMixin
from django.views.decorators.http import require_GET
from django.urls import (reverse, reverse_lazy)
from django.shortcuts import render

class HomePage(ListFilteredMixin, AjaxListView):
    template_name = 'index.html'
    page_template = 'index_page.html'
    model = models.Festival
    paginate_by = 12
    context_object_name = 'festivals'
    filter_set = FestivalFilter

用于分页的AjaxListView与过滤任务无关。

模板过滤器菜单：

<form action="" method="get" id="filter-form">

    <div class="row filters-row text-center">
      {% for style in filter.form.style %}
      {% if forloop.counter == 4 %}
      </div><div class="row filters-row text-center">
      {% endif %}
      <div class="col col-pad">
      {{ style.tag }}
      <label for="{{ style.id_for_label }}"><span id="{{ style.id_for_label }}"></span></br> {{ style.choice_label }}</label>
      </div>
    {% endfor %}
    ...
    ...
    </div>

任何帮助将不胜感激=]谢谢！
