Django jinja2模板，扩展了另一个模板。 Django渲染没有jinja2的基本模板

Question

我正在使用jinja2在django中渲染模板：

TEMPLATES = [
    {
        "BACKEND": "django.template.backends.jinja2.Jinja2",
        "DIRS": [os.path.join(BASE_DIR, "templates/jinja2/")],
        "APP_DIRS": True,
        "OPTIONS": {"environment": "management.jinja2_conf.environment"},
    },
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [],
        "APP_DIRS": True,
        "OPTIONS": {
            "context_processors": [
                "django.template.context_processors.debug",
                "django.template.context_processors.request",
                "django.contrib.auth.context_processors.auth",
                "django.contrib.messages.context_processors.messages",
            ]
        },
    },
]

初始模板位于myproject/foo/templates/jinja2/...中。 Jinja似乎觉得很好。该模板扩展了myproject/templates/jinja2/...中的基本模板。找不到这个。奇怪的是，根据模板加载器事后分析，当django搜索基本模板时，它不使用jinja2-它仅使用通常的django后端。我不知道为什么会这样...

验尸：

Django tried loading these templates, in this order:

Using engine django:
    * django.template.loaders.app_directories.Loader: /Users/foo/.pyenv/versions/management/lib/python3.7/site-packages/django/contrib/admin/templates/base_email.plain (Source does not exist)
