Django views OpenStack Horizon-LinkAction未向视图传递数据

我的一个数据表中有一个问题-单击表的LinkAction时，它不会将数据传递到相应的视图。 我需要与您选择更新现有网络记录时获得的体验相同。在那里，当您单击“编辑”行操作时，相应的表单将填充该网络数据。 在我的例子中，我有一个自定义的仪表板/面板/选项卡/表格。因此，当我单击该表行中的“编辑”链接操作时，我确实会显示我的表单，但不会从该行传递任何数据。。 这是我的表和操作（tables.py）：

这是我的更新视图（views.py）：

这是我的表格（forms.py）：

如何使此表和视图将行数据传递到表单？
