django-debug-toolbar-1.4在openstack horizon上的使用笔记

下载： https://github.com/django-debug-toolbar/django-debug-toolbar/archive/1.4.zip

安装：

cd /home/dev/django-debug-toolbar-1.4

python ./setup.py  install

配置： http://django-debug-toolbar.readthedocs.org/en/1.4/

[root@mhtcloud openstack_dashboard]# vi /usr/share/openstack-dashboard/openstack_dashboard/settings.py

增加红色部分：

MIDDLEWARE_CLASSES = (

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

)

if django.VERSION >= (1, 8, 0):

    MIDDLEWARE_CLASSES += (

        'django.contrib.auth.middleware.SessionAuthenticationMiddleware',)

else:

    MIDDLEWARE_CLASSES += ('django.middleware.doc.XViewMiddleware',)

MIDDLEWARE_CLASSES += (

    'horizon.middleware.HorizonMiddleware',

    'django.middleware.locale.LocaleMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

)

MIDDLEWARE_CLASSES += ('debug_toolbar.middleware.DebugToolbarMiddleware',)

}

关于 DEBUG_TOOLBAR_CONFIG的更多可用选项，参见：

https://django-debug-toolbar.readthedocs.org/en/1.4/configuration.html

最后还要打开debug开关：

root@mhtcloud openstack_dashboard]# cat  settings.py | grep DEBUG DEBUG = False TEMPLATE_DEBUG = DEBUG [root@mhtcloud openstack_dashboard]# cat  /etc/openstack-dashboard/local_settings | grep DEBUG DEBUG = False TEMPLATE_DEBUG = DEBUG

修改  /etc/openstack-dashboard/local_settings：

DEBUG =  True

TEMPLATE_DEBUG =  True

修改 /usr/share/openstack-dashboard/openstack_dashboard/urls.py：

if settings.DEBUG:

    import debug_toolbar

    urlpatterns += patterns(

        '',

        url(r'^500/$', 'django.views.defaults.server_error') ,

        url(r'^__debug__/', include(debug_toolbar.urls)),

    )
