Django debugging tool django-debug-toolbar installation and usage tutorial

In website development, it is inevitable to debug the page. When using django to develop the site, you can use django-debug-toolbar for debugging. Installing this plug-in is very useful. I initially wanted to view all the context variable values ​​​​in a certain page. Of course, you can also see various information such as HTTP headers, templates, caches, etc. In short, it is very comprehensive and easy to use.

In the past, I was more accustomed to installing pycharm in Windows for development. The project was deployed in a virtual machine and the effect was viewed in a local browser. This method would be a bit troublesome in debugging. The emergence of django-debug-toolbar solved this problem.

Here's how to install and use django-debug-toolbar:

1. Install

Use the command

sudo pip install django-debug-toolbar

Install django-debug-toolbar. (Note that Django version and debug_toolbar version are compatible. If you don’t have pip, please install it first. See tutorial: Detailed explanation of python package manager pip installation)

2. 配置

Add 'debug_toolbar.middleware.DebugToolbarMiddleware' to the project in settings.py within MIDDLEWARE_CLASSES.

Add INTERNAL_IPS = ('127.0.0.1',) in settings.py, (from which ip to access the site, show debug_toolbar)

Add 'debug_toolbar' in INSTALLED_APPS

Make sure the DEBUG option is true

Add 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',
]

Okay, you are done here. Note that if you create a new site for testing debug_tool, be sure to render a template so that the site has an accessible page, otherwise you will not get the debug_tool interface.
