Question

模板标记{％if％} {％endif％}无效。我需要在搜索查询后才显示页面上的搜索结果。但由于某种原因，当页面加载时，所有现有内容立即出现。但是在get请求过滤器正常工作之后。

views.py

 def search(request):
        place_list = Places.objects.all()
        place_filter = PlaceFilter(request.GET, queryset=place_list)
        return render(request, 'search/user_list.html', {'filter': place_filter})

HTML

{% if filter.qs %}

<div class="row">
    {% for obj in filter.qs %}
    <div class="col-md-3 admin__block">
    <div class="cover__wrapper">
    <img src="{{ obj.main_photo.url }}" alt="">
    <a href="#"><span>#</span>{{ obj.name }}</a>
    <p>{{ obj.description }}</p>
    </div>                  
    </div>
    {% endfor %}        
</div>

{% endif %}

filters.py

class PlaceFilter(django_filters.FilterSet):
    name = django_filters.CharFilter(lookup_expr='icontains', widget=forms.TextInput(attrs={
            'placeholder': 'Search place', 'class': 'input__search'}))
    class Meta:
        model = Places
        fields = ['name']

FilterSet＆＃39; qs属性返回filterset＆＃39; s queryset。所以它总是True。您可以在模板中使用request.GET来检查GET是否包含任何请求数据，并仅渲染过滤后的数据：

{% if request.GET %}

<div class="row">
    {% for obj in filter.qs %}
    <div class="col-md-3 admin__block">
    <div class="cover__wrapper">
    <img src="{{ obj.main_photo.url }}" alt="">
    <a href="#"><span>#</span>{{ obj.name }}</a>
    <p>{{ obj.description }}</p>
    </div>                  
    </div>
    {% endfor %}        
</div>

{% endif %}
