This command-line tool reads django settings, then tries to connect to configured postgresql server until connection succeeds. It is useful on service startup, when you want to launch migrations right after postgres database gets ready.

Installation

pip install pgwait

Usage

To wait before migrations:

pgwait && ./manage.py migrate

Specifying settings path

You can either set DJANGO_SETTINGS_MODULE environment variable, or specify settings module path in the first command-line argument.

pgwait path.to.settings
