禁用debugtoolbar会导致Mako错误

Question

我有一个金字塔应用程序，当我设置.ini包含文件：

pyramid.includes =
    pyramid_debugtoolbar
    pyramid_tm

但如果我把事情改成：

^{pr2}$

发生这种情况：

ValueError: No such renderer factory .mak

我很想知道为什么。在

套用：

问题是为什么会发生这种情况，而不是如何解决它。。。在项目中使用了mako，一切正常。这个错误只在我禁用debugtoolbar时发生。那么debugtoolbar在某种程度上使mako对应用程序可用？怎样？在

Answer 1

问题是

ValueError: No such renderer factory .mak

默认情况下，棱锥不再依赖或配置Mako和Chameleon模板系统渲染器。在

Support for Mako templating has been moved into an add-on package named pyramid_mako, and support for Chameleon templating has been moved into an add-on package named pyramid_chameleon. These packages are drop-in replacements for the old built-in support for these templating langauges. All you have to do is install them and make them active in your configuration to register renderer factories for .pt and/or .mako (or .mak) to make your application work again.
