Do Django generic foreign key lookups in one query

Project description

Django Fast Generic Foreign Keys

Travis

Travis

Overview

Generic foreign keys are incredibly powerful but can’t be prefetched, leading to a large number of SQL queries when accessing a generic foreign key field while iterating over a queryset. This app provides a function that reduces the number of SQL queries to 1 + (number of content types included in the set of generic foreign keys).

Installation

  1. Install or add django-fast-gfk to your Python path.

Usage

The fetch function returns a generator with the generic foreign key prefetched. Parameter field is the name of the generic foreign key.:

from fast_gfk import fetch

fetch(Bar.objects.all(), field="target"))
