Question

我正在使用Django == 1.4.5，Python == 2.7.5并尝试使用像django-debug-toolbar这样的探查器。我已按照文档操作并在我的本地设置中应用了以下设置： -

如果DEBUG： INTERNAL_IPS =（＆＃39; 127.0.0.1＆＃39;，） MIDDLEWARE_CLASSES + =（＆＃39; debug_toolbar.middleware.DebugToolbarMiddleware＆＃39 ;, ）

INSTALLED_APPS += (
    'debug_toolbar',
)

DEBUG_TOOLBAR_PATCH_SETTINGS = False
DEBUG_TOOLBAR_PANELS = [
    'debug_toolbar.panels.versions.VersionsPanel',
    'debug_toolbar.panels.timer.TimerPanel',
    'debug_toolbar.panels.settings.SettingsPanel',
    'debug_toolbar.panels.headers.HeadersPanel',
    'debug_toolbar.panels.request.RequestPanel',
    'debug_toolbar.panels.sql.SQLPanel',
    'debug_toolbar.panels.staticfiles.StaticFilesPanel',
    'debug_toolbar.panels.templates.TemplatesPanel',
    'debug_toolbar.panels.cache.CachePanel',
    'debug_toolbar.panels.signals.SignalsPanel',
    'debug_toolbar.panels.logging.LoggingPanel',
    'debug_toolbar.panels.redirects.RedirectsPanel',
]

DEBUG_TOOLBAR_CONFIG = {
    'INTERCEPT_REDIRECTS': False,
}

我收到此错误＆＃39; NoneType＆＃39;对象没有属性＆＃39; _meta＆＃39;

Traceback:

Exception Type: AttributeError at /
Exception Value: 'NoneType' object has no attribute '_meta'

请咨询

抛出'NoneType'对象的Django调试工具栏没有属性'_meta'
