Как связать строку со страницы django_table с подробной страницей этой строки?

/ 11 июня 2019

Я пытаюсь связать django_table с подробной страницей, которая отображает эту строку с некоторыми дополнительными данными.

Я перепробовал все учебники, которые смог найти, чтобы связать столбцы таблицы с идентификатором. В документации не так много подробностей, как это сделать.

Здесь, в CustomerListView, все работает нормально. Я могу отобразить свои блоки фильтров и таблицу, но не могу понять, как связать результаты с деталями

    group_required = u'company-user'

    filter_class = CustomerListFilter
    formhelper_class = CustomerListFormHelper

    def get_queryset(self):
        qs = super(CustomerListView, self).get_queryset()
        return qs

    def post(self, request, *args, **kwargs):
        return PagedFilteredTableView.as_view()(request)

    def get_context_data(self, **kwargs):
        context = super(CustomerListView, self).get_context_data(**kwargs)
        context['nav_customer'] = True
        search_query = self.get_queryset()
        table = CustomerTable(search_query)
        RequestConfig(self.request, paginate={'per_page': 20}).configure(table)
        context['table'] = table
        return context
