Bug reports and feature requests

You can report bugs and request features in the bug tracker.

Please search the existing database for duplicates before filing an issue.


The code is available on GitHub. Unfortunately, the repository contains old and flawed objects, so if you have set fetch.fsckObjects you’ll have to deactivate it for this repository:

git clone --config fetch.fsckobjects=false

Once you’ve obtained a checkout, you should create a virtualenv and install the libraries required for working on the Debug Toolbar:

$ python -m pip install -r requirements_dev.txt

You can run now run the example application:

$ DJANGO_SETTINGS_MODULE=example.settings python -m django migrate
$ DJANGO_SETTINGS_MODULE=example.settings python -m django runserver

For convenience, there’s an alias for the second command:

$ make example

Look at example/ for running the example with another database than SQLite.


Once you’ve set up a development environment as explained above, you can run the test suite for the versions of Django and Python installed in that environment:

$ make test

You can enable coverage measurement during tests:

$ make coverage

You can also run the test suite on all supported versions of Django and Python:

$ tox

This is strongly recommended before committing changes to Python code.

The test suite includes frontend tests written with Selenium. Since they’re annoyingly slow, they’re disabled by default. You can run them as follows:

$ make test_selenium

or by setting the DJANGO_SELENIUM_TESTS environment variable:

$ DJANGO_SELENIUM_TESTS=true make test
$ DJANGO_SELENIUM_TESTS=true make coverage

At this time, there isn’t an easy way to test against databases other than SQLite.


The Django Debug Toolbar uses black to format code and additionally uses flake8 and isort. You can reformat the code using:

$ make style


Please submit pull requests!

The Debug Toolbar includes a limited but growing test suite. If you fix a bug or add a feature code, please consider adding proper coverage in the test suite, especially if it has a chance for a regression.


Translation efforts are coordinated on Transifex.

Help translate the Debug Toolbar in your language!

Making a release

Prior to a release, the English .po file must be updated with make translatable_strings and pushed to Transifex. Once translators have done their job, .po files must be downloaded with make update_translations.

The release itself requires the following steps:

  1. Update supported Python and Django versions:

    • python_requires list

    • trove classifiers

    • README.rst


  2. Update the screenshot in README.rst.

    $ make example/django-debug-toolbar.png


  3. Bump version numbers in docs/changes.rst, docs/, README.rst and Add the release date to docs/changes.rst. Commit.

  4. Tag the new version.

  5. python sdist bdist_wheel upload.

  6. Push the commit and the tag.

  7. Change the default version of the docs to point to the latest release:
