Note - This repository is archived. All of the functionality previously offered by django-pgconnection is now available in Django's connection hooks

django-pgconnection

django-pgconnection provides primitives for overriding Postgres connection and cursor objects, making it possible to do the following:

1. Hook into SQL generation. For example, it is not possible to log every time a SQL statement is executed in Django or annotate SQL with comments so that additional metadata is logged when executing queries. The pgconnection.pre_execute_hook context manager allows one to hook into SQL before it is executed.
2. Route database traffic to a different database. Although Django provides the ability to construct custom database routers, routing to a different database has to be instrumented throughout code and can be tedious and error prone. The pgconnection.route context manager can route any database operations to a different database, even if it's an external management command that has not been instrumented to use a different database.

The documentation has examples of how to use django-pgconnection.

Installation

Install django-pgconnection with:

pip3 install django-pgconnection

After this, add pgconnection to the INSTALLED_APPS setting of your Django project.

In order to use connection routing and hooks, one must configure the DATABASES setting in settings.py like so:

DATABASES = pgconnection.configure({
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase',
    }
})
