Question

我使用django-admin创建了一个非常基本的Django项目，当我在manage.py runserver运行时尝试在浏览器中查看我的管理应用程序时，我遇到了以下问题：

ImproperlyConfigured at /admin/
Module "django.template.loaders.filesystem" does not define a "Loader" callable template source loader

作为参考，这是我的settings.py文件：

# Django settings for mine project.

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', 'your_email@domain.com'),
)

MANAGERS = ADMINS

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '/tmp/mine.db',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

DATABASE_ENGINE = 'sqlite3'
DATABASE_NAME = '/tmp/mine.db'
DATABASE_USER = ''
DATABASE_PASSWORD = ''
DATABASE_HOST = ''

# Local time zone for this installation. Choices can be found here:
# http://en.wikipedia.org/wiki/List_of_tz_zones_by_name
# although not all choices may be available on all operating systems.
# On Unix systems, a value of None will cause Django to use the same
# timezone as the operating system.
# If running in a Windows environment this must be set to the same as your
# system time zone.
TIME_ZONE = 'America/Los_Angeles'

# Language code for this installation. All choices can be found here:
# http://www.i18nguy.com/unicode/language-identifiers.html
LANGUAGE_CODE = 'en-us'

SITE_ID = 1

# If you set this to False, Django will make some optimizations so as not
# to load the internationalization machinery.
USE_I18N = True

# If you set this to False, Django will not format dates, numbers and
# calendars according to the current locale
USE_L10N = True

# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT = ''

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash if there is a path component (optional in other cases).
# Examples: "http://media.lawrence.com", "http://example.com/media/"
MEDIA_URL = ''

# URL prefix for admin media -- CSS, JavaScript and images. Make sure to use a
# trailing slash.
# Examples: "http://foo.com/media/", "/media/".
ADMIN_MEDIA_PREFIX = '/media/'

# Make this unique, and don't share it with anybody.
SECRET_KEY = 'secret'

# List of callables that know how to import templates from various sources.
TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
#     'django.template.loaders.eggs.Loader',
)

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    #'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    #'django.contrib.messages.middleware.MessageMiddleware',
)

ROOT_URLCONF = 'mine.urls'

TEMPLATE_DIRS = (
    # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
)

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    #'django.contrib.messages',
    'django.contrib.admin',
    'mine.main',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
)

我必须注释掉一堆你可以看到的东西，我不得不使用一种不同的方式来定义我的数据库而不是他们提供的数据库。如果我在那里留下一些其他物品，我还会抛出其他错误。我做错了什么？

Answer 1

Here您可以看到正确的加载程序包路径。在我看来，你应该使用它们。

django.template.loaders.filesystem.Loader
django.template.loaders.app_directories.Loader

Answer 2

另一种解决方法是升级Django安装。

该settings.py文件似乎是为更新版本的Django创建的，而不是当前安装的文件。

Loader已添加到this revision中的django.template.loaders.filesystem。

Answer 3

似乎您可能想要注释掉下面的一个数据库设置，因为第二组数据库连接设置似乎是多余的：

    DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': '/tmp/mine.db',                      # Or path to database file if using sqlite3.
    'USER': '',                      # Not used with sqlite3.
    'PASSWORD': '',                  # Not used with sqlite3.
    'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
    'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
       }
    }

   #DATABASE_ENGINE = 'sqlite3'
   #DATABASE_NAME = '/tmp/mine.db'
   #DATABASE_USER = ''
   #DATABASE_PASSWORD = ''
   #DATABASE_HOST = ''

Django：模块“django.template.loaders.filesystem”没有定义“Loader”可调用模板源加载器
