Installation
Install with pip:
python -m pip install django-read-onlyThen add to your installed apps:
INSTALLED_APPS = [
...,
"django_read_only",
...
]Usage
Set the environment variable DJANGO_READ_ONLY to anything but the empty string, and all data modification queries will cause an exception:
DJANGO_READ_ONLY=1 python manage.py shell
...
>>> User.objects.create_user(username="hacker", password="hunter2")
...
DjangoReadOnlyError(...)You can put this in the shell profile file (bashrc, zshrc, etc.) of the user on your production system. This way developers performing exploratory queries can’t accidentally make changes, but writes remain enabled for non-shell processes like your WSGI server.
During a session with DJANGO_READ_ONLY set, you can re-enable writes for the current thread by calling enable_writes():
>>> import django_read_only
>>> django_read_only.enable_writes()Writes can be disabled with disable_writes():
>>> django_read_only.disable_writes()To temporarily allow writes, use the temp_writes() context manager / decorator:
>>> with django_read_only.temp_writes():
... User.objects.create_user(...)1 maintainer
