Configuring Django Doctor

Django Doctor checks over 40 security, performance, and maintainability problems.

This can be customized using a pyproject.toml file: add it to the root of your project and specify some check codes in enable and disable, like the examples below.

View the list of check codes here.
What is a pyproject.toml file? Read here.

Examples of Django Doctor pyproject.toml configuration

Example 1: Disable one check



disable = ["redundant-settings"]

Example 2: Disable multiple checks



disable = ["redundant-settings", "missing-hsts-subdomain"]

Example 3: Disable everything except x



disable = ["all"]

enable = ["redundant-settings", "missing-hsts-subdomain"]

Example 4: Targeting sub-directories and ignoring folders



directories = ["my_app_one", "my_app_two"]

ignore = ["my_app_one/tests", "my_app_two/tests"]

Check codes

Use these codes in the enable and disbale section of your pyproject.toml file to customize the checks that Django Doctor performs.
