Django debugging tool-debug-toolbar installation tutorial

The Django debugging tool django-debug-toolbar installation and usage tutorials inevitably require debugging pages in website development. when using the django development site, you can use django-debug-toolbar for debugging, installing this plug-in is very useful. I first wanted to view all the context variable values on a page. of course, you can also see the HTTp header, Template, cache, and other information, in short, it is comprehensive and easy to use.

In the past, I used to install pycharm development in windows, deploy projects in virtual machines, and view the results in a local browser. this method may be a bit difficult for debugging, and django-debug-toolbar may appear, solved this problem.

The following describes how to install and use django-debug-toolbar:

1. install

Use commands

sudo pip install django-debug-toolbar

Install django-debug-toolbar. (Note that the Django version and debug_toolbar version are compatible. if there is no pip, install it first. for details, see The Tutorial: how to install python package manager pip)

2. configuration

In settings. py, add 'debug _ toolbar. middleware. DebugToolbarMiddleware 'to the MIDDLEWARE_CLASSES of the project.

Add INTERNAL_IPS = ('192. 0.0.1 ',) to settings. py)

Add 'debug _ Toolbar' to INSTALLED_APPS'

Make sure that the DEBUG option is true.

Add the DEBUG_TOOLBAR_PANELS option

Finally, set the template and add the template directory of debug_toolbar to TEMPLATE_DIRS.

The code is as follows:

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',]

All right, this is done. Note: If you have created a new site to test debug_tool, make sure to render a template so that the site has an accessible page. Otherwise, you cannot obtain the debug_tool interface.
