django.contrib.staticfiles.finders.find 需要帮助

Question

我有以下 Django 项目布局：

project_folder/
    app_folder/
        static/
           folder1/
               file1
        templates/
        ...
    compressor -> (symlink to django_compressor app with my modifications)
    __init__.py
    manage.py
    settings.py
    urls.py

从 django_compressor 的 fork 中指定的 templatetag 中，我调用一个执行以下操作的类：

class StorageMixin(object):
    from django import VERSION as DJANGO_VERSION
    if DJANGO_VERSION[:2] >= (1, 3):
        from django.contrib.staticfiles.finders import find as _django_find
        def _find_file_path(self, path):
            return self._django_find(path)
    else:
        def _find_file_path(self, path):
            static_roots = getattr(settings, 'STATIC_ROOTS', []) + [settings.COMPRESS_ROOT]
            for root in static_roots:
                filename = os.path.join(root, basename)
                if os.path.exists(filename):
                    return filename
            return None

因此，如果 django 是新版本，它会尝试使用 staticfiles 查找器，否则模仿其基本查找器通过 STATIC_ROOTS 配置变量。

最后，问题是：给定上面的文件夹布局，我将 "folder1/file1" 传递给 finders.find 方法，并且我有以下设置：

INSTALLED_APPS = (

    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'compressor',
    'app_folder',
)

并且

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
#     'django.template.loaders.eggs.Loader',
)

我得到 <来自 find 调用的 code>None。

有什么想法吗？

UPD。更奇怪的细节：我跑了

python manage.py shell

并且做了

from django.contrib.staticfiles.finders import find
find("folder1/file1")

它给了我正确的结果......

Answer 1

答案是：导入整个模块，而不仅仅是 find 方法

Answer 2

我在新网站中使用静态文件，需要一段时间才能设置。你的settings.py里有类似的东西吗？
