Installation

Each of the following steps needs to be configured for the Debug Toolbar to be fully functional.

Getting the code

The recommended way to install the Debug Toolbar is via pip:

$ pip install django-debug-toolbar

If you aren’t familiar with pip, you may also obtain a copy of the debug_toolbar directory and add it to your Python path.

To test an upcoming release, you can install the in-development version instead with the following command:

$ pip install -e git+https://github.com/jazzband/django-debug-toolbar.git#egg=django-debug-toolbar

Prerequisites

Make sure that 'django.contrib.staticfiles' is set up properly and add 'debug_toolbar' to your INSTALLED_APPS setting:

INSTALLED_APPS = [
    # ...
    'django.contrib.staticfiles',
    # ...
    'debug_toolbar',
]

STATIC_URL = '/static/'

If you’re upgrading from a previous version, you should review the change log and look for specific upgrade instructions.

Setting up URLconf

Add the Debug Toolbar’s URLs to your project’s URLconf as follows:

from django.conf import settings
from django.conf.urls import include, url  # For django versions before 2.0
from django.urls import include, path  # For django versions from 2.0 and up

if settings.DEBUG:
    import debug_toolbar
    urlpatterns = [
        path('__debug__/', include(debug_toolbar.urls)),

        # For django versions before 2.0:
        # url(r'^__debug__/', include(debug_toolbar.urls)),

    ] + urlpatterns

This example uses the __debug__ prefix, but you can use any prefix that doesn’t clash with your application’s URLs. Note the lack of quotes around debug_toolbar.urls.

Enabling middleware

The Debug Toolbar is mostly implemented in a middleware. Enable it in your settings module as follows:

MIDDLEWARE = [
    # ...
    'debug_toolbar.middleware.DebugToolbarMiddleware',
    # ...
]

Warning

The order of MIDDLEWARE is important. You should include the Debug Toolbar middleware as early as possible in the list. However, it must come after any other middleware that encodes the response’s content, such as GZipMiddleware.

Configuring Internal IPs

The Debug Toolbar is shown only if your IP address is listed in the INTERNAL_IPS setting. This means that for local development, you must add '127.0.0.1' to INTERNAL_IPS; you’ll need to create this setting if it doesn’t already exist in your settings module:

INTERNAL_IPS = [
    # ...
    '127.0.0.1',
    # ...
]

You can change the logic of determining whether or not the Debug Toolbar should be shown with the SHOW_TOOLBAR_CALLBACK option. This option allows you to specify a custom function for this purpose.
