在安装 askbot 之前，该应用程序运行良好。我检查了他们的文档并将 askbot 安装为可插入应用程序。而且我还合并了设置和网址。现在论坛部分(askbot 应用程序)工作正常，但包括索引在内的其他部分已经崩溃。
错误如下:

请帮我解决这个问题。我尝试了很多谷歌搜索，但没有用。而且我也不能在 askbot 论坛上发布这个，因为我的业力很低。
最佳答案
Askbot 使用 Jinja2 模板，您的“index.html”模板(我猜是 Django 模板)可能扩展了 askbot 的“基本”模板 - Jinja2 模板。
看来错误不是模板解析错误，而是API错误。当顶级模板和基本模板都被找到并正确解析时，可能会发生这种情况，但由于模板引擎的内部 api 不兼容，它们无法放在一起。
也许解决方案是创建基本模板的 Django 版本并将其放在不同的目录中。
当部分项目使用 Django 模板时，Askbot 确实可以工作 - 例如 - 我们的/settings/url 映射到 livesettings 应用程序，它使用 Django 模板并且两者都可以正常工作，但它们使用不同的基础模板。
为了快速测试 - 创建一个简单的基本模板并将其用于 index.html。
关于python - 安装 askbot 后 Django 应用程序未运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15157997/
