django-debug-toolbar not showing up

Question

I looked at other questions and can\'t figure it out...

I did the following to install django-debug-toolbar:

1. pip install django-debug-toolbar

Answer 1

In the code I was working on, multiple small requests were made during handling of main request (it's very specific use case). They were requests handled by the same Django's thread. Django debug toolbar (DjDT) doesn't expect this behaviour and includes DjDT's toolbars to the first response and then it removes its state for the thread. So when main request was sent back to the browser, DjDT was not included in the response.

Lessons learned: DjDT saves it's state per thread. It removes state for a thread after the first response.

Answer 2

you have to make sure there is a closing tag in your templates.

My problem is that there is no regular html tags in my templates, I just display content in plain text. I solved it by inheriting every html file from base.html, which has a tag.

Answer 3

I had the same problem using Vagrant. I solved this problem by adding ::ffff:192.168.33.1 to the INTERNAL_IPS as below example.

INTERNAL_IPS = (
    '::ffff:192.168.33.1',
)

Remembering that 192.168.33.10 is the IP in my private network in Vagrantfile.

Answer 4

Add 10.0.2.2 to your INTERNAL_IPS on Windows, it is used with vagrant internally

INTERNAL_IPS = ( '10.0.2.2', )

This should work.

Answer 5

For anyone who is using Pycharm 5 - template debug is not working there in some versions. Fixed in 5.0.4, affected vesions - 5.0.1, 5.0.2 Check out issue

Spend A LOT time to find that out. Maybe will help someone

Answer 6

Docker

If you're developing with a Django server in a Docker container with docker, the instructions for enabling the toolbar don't work. The reason is related to the fact that the actual address that you would need to add to INTERNAL_IPS is going to be something dynamic, like 172.24.0.1. Rather than trying to dynamically set the value of INTERNAL_IPS, the straightforward solution is to replace the function that enables the toolbar, in your settings.py, for example:

DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': lambda _request: DEBUG
}

This should also work for other dynamic routing situations, like vagrant.

Here are some more details for the curious. The code in django_debug_tool that determines whether to show the toolbar examines the value of REMOTE_ADDR like this:

if request.META.get('REMOTE_ADDR', None) not in INTERNAL_IPS:
       return False

so if you don't actually know the value of REMOTE_ADDR due to your dynamic docker routing, the toolbar will not work. You can use the docker network command to see the dynamic IP values, for example docker network inspect my_docker_network_name
