Selenium 和 django 调试工具栏

Question

我的网站使用 Django 1.11.1 和 Django 调试工具栏 1.8 运行在我的开发服务器上运行良好 (vagrant/gunicorn/nginx)。我的常规测试套件运行没问题。但是，当我告诉它运行硒测试时，它会以 'djdt' is not a registered namespace error 结束。我在 url、中间件和配置中有适当的条目。如果我卷曲 localhost，它 returns 带有调试工具栏的主页。如果我将工具栏设置为不显示 show_toolbar 代码，我的 selenium 测试仍然会崩溃，但该网站仍然可以正常工作（并且不显示调试工具栏）。

关于如何让我的 selenium 测试达到运行的想法？

Answer 1

显然，如果您正在进行 selenium 测试，答案是不加载 django_debug_toolbar。

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

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

Answer 2

如果您希望看到 django 调试工具栏。如果是 django 1.11 ，那么请尝试下面的代码。将 "patterns" 替换为 []（列表）。我在 django-debug-toolbar 1.8 中测试过

if settings.DEBUG:
    import debug_toolbar
    urlpatterns += [
    url(r'^__debug__/', include(debug_toolbar.urls)),
    ]

请查看其他内容，例如

DEBUG = True
MIDDLEWARE_CLASSES = ['debug_toolbar.middleware.DebugToolbarMiddleware',]
INTERNAL_IPS = ['127.0.0.1',]（相应地添加 ip）
