我可以在 Django generic.ListView 中有多个列表吗? [英] Can I have multiple lists in a Django generic.ListView?

问题描述

作为一个 Django 初学者，我正在研究 django 文档提供的教程，位于 https://docs.djangoproject.com/en/1.5/intro/tutorial04/

As a Django beginner I'm working on the the tutorial provided by django docs at https://docs.djangoproject.com/en/1.5/intro/tutorial04/

在其中，他们展示了使用按发布日期查询列出的多个民意调查的列表.我可以添加另一个列表，也可以在要使用的模板中使用.示例 在同一页面上按日期显示最新民意调查列表，并按字母顺序显示另一个.

In it they demonstrate a list of multiple polls that are listed using a query by publication date. Could I add another list to be also used in the template to be used as well. Example Displaying a list of latest polls by date and another by alphabetical order on the same page.

class IndexView(generic.ListView):
    template_name = 'polls/index.html'
    context_object_name = 'latest_poll_list'

    def get_queryset(self):
        """Return the last five published polls."""
        return Poll.objects.order_by('-pub_date')[:5]

推荐答案

当然，您只需要编写自己的get_context_data"方法来检索这些值，然后它们将在视图中可用.类似的东西:

Absolutely, you'll just need to write your own 'get_context_data' method that will retrieve those values and then they will be available in the view. Something like:

def get_context_data(self, *args, **kwargs):
    context = super(IndexView, self).get_context_data(*args, **kwargs)
    context['alphabetical_poll_list'] = Poll.objects.order_by('name')[:5]
    return context 

有了这个 {{ latest_poll_list }} 和 {{alphabetical_poll_list }} 都可以在你的模板中使用.

With this both {{ latest_poll_list }} and {{ alphabetical_poll_list }} would be available in your template.
