django - 如何从 Jinja 的扩展中访问上下文变量？
我通过棺材使用django+jinja2，我不明白如何访问扩展中的上下文变量。例如，我有这个：
所以我需要a在方法中获取变量render。我该怎么做？
python - 带有棺材扩展的 Babel 和 jinja2
我正在尝试使用命令行工具用 Babel 翻译 jinja2/coffin 模板。问题是函数 babel_extract 卡在 {% url %} 或 {% csrf_token %} 等棺材标签上。
首先，为了检测问题，我修改了 jinja.ext.babel_extract 并在渲染时在异常上添加了“print e”。
当我使用 Babel 运行 extract 方法时，它会打印出以下错误：
然后我编辑了我的 babel 配置以添加棺材库。我还设置了环境变量以将我的 django 项目添加到我的 python 路径并将 django 设置模块设置为我的 settings.py。
现在，当我运行 extract 方法时，会发生此错误：
