Python Selenium和django调试工具栏

我的带有Django 1.11.1和Django debug toolbar 1.8的网站在我的开发服务器（vagrant/gunicorn/nginx）上运行良好。我的常规测试套件运行良好。但是，当我告诉它运行selenium测试时，它会死掉，出现

“djdt”不是注册的名称空间错误。我在URL、中间件和配置中有相应的条目。如果我使用curl localhost，它将返回带有调试工具栏的主页。如果我将工具栏设置为不显示show_工具栏代码，我的selenium测试仍然会崩溃，但网站仍然可以正常工作（并且不显示调试工具栏）

关于如何运行selenium测试的想法

显然，如果您正在进行selenium测试，那么答案是不要加载django_debug_工具栏

import sys
TESTING = len(sys.argv) > 1 and sys.argv[1] == 'test'

if not TESTING:
    MIDDLEWARE += ('debug_toolbar.middleware.DebugToolbarMiddleware',)
    INSTALLED_APPS += ('debug_toolbar', )


如果希望看到django调试工具栏。
如果是django 1.11，请尝试下面的代码。将“模式”替换为[]（列表）。我在django调试工具栏1.8中进行了测试


请检查其他事项，如

调试=真

MIDDLEWARE_CLASSES=['debug_toolbar.MIDDLEWARE.DebugToolbar MIDDLEWARE'，]

内部ip=['127.0.0.1'，]（相应地添加ip）

由@Denise Mauldin发布的问题和解决方案，经django debug toolbar 1.9.1确认。其他信息：NoReverseMatch:“djdt”不是在模板…\site packages\debug\u toolbar\templates\debug\u toolbar\base.html中的模板呈现过程中注册的命名空间错误，回溯：文件“…\site packages\django\url\base.py”，反向额外，解析器=解析器.namespace\u dict[ns]
if settings.DEBUG:
    import debug_toolbar
    urlpatterns += [
    url(r'^__debug__/', include(debug_toolbar.urls)),
    ]
