python - FutureWarning : `TemplateForHostMiddleware` is deprecated. 请升级到模板加载器

Question

我正在构建一个 mezzanine网站。

我通过键入 pip install mezzanine 安装了 mezzanine，这安装了 django 1.9 (IIRC) 和 mezzanine。

然后我安装了cartridge , 将 django 升级到 1.10.8 版本。

现在，当我在命令行运行 runserver 时，我在命令行收到以下警告:

/path/to/env/lib/python3.5/site-packages/django/core/handlers/base.py:58: FutureWarning: TemplateForHostMiddleware` is deprecated. Please upgrade to the template loader.

我该如何解决此警告 - 因为警告不是很清楚(即升级哪个 模板加载器以及升级模板加载器是什么意思？ )

Answer 1

参见 this portion解释正在发生的事情的文档:

Mezzanine implements host-specific templates using a template loader since version 4.3. Prior to that, the TemplateForHostMiddleware was used. If you are upgrading from a version lower than 4.3 and getting warnings in the terminal about TemplateForHostMiddleware, edit your settings.py to switch to the new loader-based approach:

• Remove TemplateForHostMiddleware from your MIDDLEWARE or MIDDLEWARE_CLASSES setting.
• Remove "APP_DIRS": True from your TEMPLATES setting.
• Add mezzanine.template.loaders.host_themes.Loader to the list of template loaders.

Your TEMPLATES setting should look like this (notice the "loaders" key):

TEMPLATES = [
  {
      "BACKEND": "django.template.backends.django.DjangoTemplates",
      "DIRS": [...],
      "OPTIONS": {
          "context_processors": [...],
          "builtins": [...],
          "loaders": [
              "mezzanine.template.loaders.host_themes.Loader",
              "django.template.loaders.filesystem.Loader",
              "django.template.loaders.app_directories.Loader",
          ]
      },
  },
]

看起来对文档的这种更改还没有实现 http://mezzanine.jupo.org/docs/multi-tenancy.html .
