Question

我有一个资产详细信息视图，该视图使用来自另外两个模型（租户和服务）的数据。

asset \ views.py

class AssetMultipleDetailView(LoginRequiredMixin, UserPassesTestMixin, DetailView):
    model = Asset
    context_object_name = 'asset'
    template_name = 'asset/asset_multiple_detail.html'

    def test_func(self):
        asset_multiple = self.get_object()
        if self.request.user == asset_multiple.owner:
            return True
        return False

    def get_context_data(self, **kwargs):
        context = super(AssetMultipleDetailView, self).get_context_data(**kwargs)
        context['tenants'] = Tenant.objects.filter(asset=context['asset']).order_by('created')
        context['services'] = Service.objects.filter(asset=context['asset']).order_by('created')
        return context

我想对 context ['tenant] 和 context ['services'] 中的数据进行分页，我不知道该如何实现。

我已经使用 paginated_by 在自己的ListViews中完成了此操作，并使其正常工作。

我只是想知道如何在DetailView中对上下文进行分页。

谢谢。

您可以按照django's example中提供的示例将分页放在视图中。像这样：

class AssetMultipleDetailView(LoginRequiredMixin, UserPassesTestMixin, DetailView):
    ...

    def get_context_data(self, **kwargs):
        context = super(AssetMultipleDetailView, self).get_context_data(**kwargs)
        page = request.GET.get('page')
        tenants = paginator = Paginator(Tenant.objects.filter(asset=self.get_object()).order_by('created'), 5)  # will show 5 items in one page
        services = Paginator(Service.objects.filter(asset=self.get_object()).order_by('created'), 5)
        context['tenants'] = tenants.get_page(page)
        context['services'] = services.get_page(page)
        return context

并像这样更新模板：

// tenants pages
<div class="pagination">
    <span class="step-links">
        {% if tenants.has_previous %}
            <a href="?page=1">&laquo; first</a>
            <a href="?page={{ tenants.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ tenants.number }} of {{ tenants.paginator.num_pages }}.
        </span>

        {% if tennats.has_next %}
            <a href="?page={{ tenants.next_page_number }}">next</a>
            <a href="?page={{ tenants.paginator.num_pages }}">last &raquo;</a>
        {% endif %}
    </span>
</div>

// services
<div class="pagination">
    <span class="step-links">
        {% if services.has_previous %}
            <a href="?page=1">&laquo; first</a>
            <a href="?page={{ services.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ services.number }} of {{ services.paginator.num_pages }}.
        </span>

        {% if services.has_next %}
            <a href="?page={{ services.next_page_number }}">next</a>
            <a href="?page={{ services.paginator.num_pages }}">last &raquo;</a>
        {% endif %}
    </span>
</div>

在Django的DetailView中分页上下文
