Fix: Django Debug Toolbar not showing when using with Docker.

option1.py

# YOU MAY WANT TO CHECK THIS OUT: https://github.com/douglasmiranda/ddpt/blob/master/{{cookiecutter.django_project_name}}/{{cookiecutter.django_project_name}}/config/local.py

# If you don't do this you will have to add the host IP in INTERNAL_IPS = ('127.0.0.1',)
# And it will change, then you will have to change INTERNAL_IPS again.

def show_toolbar(request):
    if request.is_ajax():
        return False
    return True

DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': 'config.local.show_toolbar',
}

option2.py

# Depending on your requirements, you can do:
import socket
import os

hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
INTERNAL_IPS = [ip[:-1] + '1' for ip in ips] + ['127.0.0.1', '10.0.2.2']

thank you very much

thank you.. this fix my problem..

save me a lot of time. thanks!

Thanks! It is fix my problem!

Great!!

ip[:-1] + '1' replaces not the last octet but the last digit of the last octet. Is it intended? If so, could you please explain why it should fix an issue?

Awesome thanks!

Thanks! Just watch out if gethostbyname_ex returns IP address with the last octet longer than 1 character. Probably is more safe use something like this:

import socket
INTERNAL_IPS = ['127.0.0.1', '::1', 'localhost']

# get ip address for docker host
hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
for ip in ips:
    # replace last octet in IP with .1
    ip = '{}.1'.format(ip.rsplit('.', 1)[0])
    INTERNAL_IPS.append(ip)

Still not showing;

my settings.py

def show_toolbar(request):
    if DEBUG:
        return True
    return False

DEBUG_TOOLBAR_CONFIG = {
    "SHOW_TOOLBAR_CALLBACK" : show_toolbar,
}

hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
INTERNAL_IPS = [ip[:-1] + '1' for ip in ips] + ['127.0.0.1', 'x.x.x.x','x.x.x.x']

The toolbar wouldn't show when I run on docker.

Hey @rhonaldmoses take a look in a more up to date code:

INSTALLED_APPS += ['debug_toolbar', ]
MIDDLEWARE = ['debug_toolbar.middleware.DebugToolbarMiddleware'] + MIDDLEWARE
hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
INTERNAL_IPS = [ip[:-1] + '1' for ip in ips] + ['127.0.0.1', '10.0.2.2']

Not using SHOW_TOOLBAR_CALLBACK anymore.

From douglasmiranda/ddpt.

Unfortunately it still wouldn't show up. This is what my settings.py looks like

INSTALLED_APPS = [
...
'debug_toolbar',
]

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

hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
INTERNAL_IPS = [ip[:-1] + '1' for ip in ips] + ['127.0.0.1', '10.0.2.2']

worked perfectly, thanks.

@douglasmiranda, boss! Thank you so much, It helped me a lot ;)

Smaller one line version:

DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': lambda request: False if request.is_ajax() else True,
}

Thank you for making us aware that the is_ajax function does what we're looking for @adamb70!

Using this lambda, we can avoid specifying INTERNAL_IPS.

Here's my full solution:

# Determine debug state.
DEBUG = os.getenv("DEBUG", "True") == "True"

# Add the debug toolbar.
if DEBUG:
    INSTALLED_APPS = INSTALLED_APPS + ['debug_toolbar']
    MIDDLEWARE = ['debug_toolbar.middleware.DebugToolbarMiddleware'] + MIDDLEWARE

    DEBUG_TOOLBAR_CONFIG = {
        'SHOW_TOOLBAR_CALLBACK': lambda request: not request.is_ajax()
    }

WHoop, gracias!

yay!!

@cgillions many thanks!

Nice!

Thanks!

Smaller one line version:

DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': lambda request: False if request.is_ajax() else True,
}

This is everything you need to add to standard config. They should add it in Installation guide

Thank you matacoder. Your solution did the trick for me.

is_ajax appears to be deprecated in Django 3.1

Great thank u so much
