当我使用样板时，Django 模型不渲染

如何解决当我使用样板时，Django 模型不渲染

当我尝试渲染时没有错误。当我不使用 django 仪表板样板时，它工作正常。我测试了在 shell 上设置的查询及其工作。数据可以在admin上看到。它只是没有在 html 模板上呈现。不确定网址设置是否会影响它。

我已尝试更改如何在模板上呈现，但仍然无法正常工作。有人知道如何纠正它吗？

解决方法

问题出在您的 urls.py 中，您没有在 url 中定义 list_tabels

path('List_tabels/',view.list_tables,name='list_tabel')
