我将 Jinja2 与 Google App Engine 一起使用。在我尝试使用相对路径来加载 base.html 与我的 edit.html 模板。
我的主题目录结构如下所示...
- 应用程序根
- 主题
- 默认
- 行政
- 编辑.html
- base.html
- 行政
- 默认
- 主题
我已经在模板中尝试过这个......
{% extends "../base.html" %}
它返回这个......
TemplateNotFound: ../base.html
当我这样做...
{% extends "base.html" %}
我的 edit.html 模板加载，但没有 base.html。
如何访问 base.html，它是 edit.html 的一个目录？
现在的代码...
