将额外上下文传递给django中的列表视图

发布于 2025-02-02 12:05:24 字数 511 浏览 1 评论 0原文

谁能告诉我如何将我的listView上的“查询”作为上下文传递，同时将“ search_results”作为Context_Object_name？我只是无法绕过它：

class SearchResulView(ListView):
    model = Product
    template_name = 'shop/product/search_results.html'
    context_object_name = 'search_results' 

    def get_queryset(self):
        query = self.request.GET.get("q")
        search_results = Product.objects.filter(
            Q(name__icontains=query)
            )
        return search_results

正在尝试将传递给“查询”的值渲染到我的模板上，但我无法弄清楚如何...

原文

Can anyone please tell me how I can pass the "query" on my ListView as a context while at the same time keeping "search_results" as a context_object_name? I just can't get my head around it:

class SearchResulView(ListView):
    model = Product
    template_name = 'shop/product/search_results.html'
    context_object_name = 'search_results' 

    def get_queryset(self):
        query = self.request.GET.get("q")
        search_results = Product.objects.filter(
            Q(name__icontains=query)
            )
        return search_results

Am trying to render the values passed to "query" on my template but I just can't figure out how...

您可以通过覆盖 .get_context_data（…） method> nbsp; ^{^{[django-doc> [django-doc]}}

class SearchResulView(ListView):
    model = Product
    template_name = 'shop/product/search_results.html'
    context_object_name = 'search_results' 

    def get_queryset(self):
        return super().get_queryset().filter(
            name__icontains=self.request.GET.get('q')
        )

    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        context['query'] = self.request.GET.get('q')
        return context

您无需覆盖.get_context_data（…）方法。在模板中，您可以使用以下方式访问此操作：

{{ view.request.GET.q }}

You can pass this by overriding the .get_context_data(…) method ^[Django-doc]:

class SearchResulView(ListView):
    model = Product
    template_name = 'shop/product/search_results.html'
    context_object_name = 'search_results' 

    def get_queryset(self):
        return super().get_queryset().filter(
            name__icontains=self.request.GET.get('q')
        )

    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        context['query'] = self.request.GET.get('q')
        return context

You however do not need to override the .get_context_data(…) method. In the template you can access this with:
