PostgreSQL specific lookups

Unaccent

The unaccent lookup allows you to perform accent-insensitive lookups using a dedicated PostgreSQL extension.

This lookup is implemented using Transform, so it can be chained with other lookup functions. To use it, you need to add 'django.contrib.postgres' in your INSTALLED_APPS and activate the unaccent extension on PostgreSQL. The UnaccentExtension migration operation is available if you want to perform this activation using migrations).

The unaccent lookup can be used on CharField and TextField:

>>> City.objects.filter(name__unaccent="México")
['<City: Mexico>']

>>> User.objects.filter(first_name__unaccent__startswith="Jerem")
['<User: Jeremy>', '<User: Jérémy>', '<User: Jérémie>', '<User: Jeremie>']
