The docker setup uses supervisord to run the django runserver. This means if you want to access the management server from a shell to run things like ipdb you still can.

Using ipdb

As with ipdb normally just add a line in your code at the relevant point:

import ipdb; ipdb.set_trace()

Next connect to the running web container:

make debug

This will bring the Django management server to the foreground and you can interact with ipdb as you would normally. To quit you can just type Ctrl+c.

All being well it should look like this:

$ make debug
docker exec -t -i olympia_web_1 supervisorctl fg olympia

Using the Django Debug Toolbar

The Django Debug Toolbar is very powerful and useful when viewing pages from the website, to check the view used, its parameters, the SQL queries, the templates rendered and their context.

To use it please see the official getting started docs:


You must know that using the Django Debug Toolbar will slow the website quite a lot. You can mitigate this by deselecting the checkbox next to the SQL panel.

Also, please note that you should only use the Django Debug Toolbar if you need it, as it makes CSP report only for your local dev.


You might have to disable CSP by setting CSP_REPORT_ONLY = True in your local settings because django debug toolbar uses “data:” for its logo, and it uses “unsafe eval” for some panels like the templates or SQL ones.
