@epicserve could you give this a test run for me?

@tim-schilling,

I tested it out and it worked. You can see my code here.

Excellent thank you. @matthiask I know this is a hack, but I personally don't see a difference between asking a developer to copy/paste the hack themselves versus us writing it in for them and letting them know where it exists. At least for a development tool like this.

I do wonder if we could setup a test that's better than a mock though. @epicserve do you have any ideas on how that could be done? I haven't researched it at all, so I apologize if it's just a search away.

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 or Heroku.

@nitairoy did you attempt to use the code in this PR? Also, please see the discussion in #1854.

[epicserve]

@tim-schilling, mocking is how I would handle testing it. I can't think of a better alternative.

[nitairoy]

Yes, I did and it work. Best Regards, Nitai Roy

Yes, I agree. It would certainly be nice if the toolbar worked out of the box for everyone.
