The PostgreSQL fuzzystrmatch extension enables several functions for fuzzy string matching: soundex(), difference(), levenshtein(), levenshtein_less_equal(), metaphone(), dmetaphone() and dmetaphone_alt().
Enabling them for use with Django turns out to be really easy - it just takes a migration that looks something like this:
\nfrom django.contrib.postgres.operations import CreateExtension\nfrom django.db import migrations\n\n\nclass Migration(migrations.Migration):\n\n dependencies = [\n (\"core\", \"0089_importrun_sourcelocation\"),\n ]\n\n operations = [\n CreateExtension(name=\"fuzzystrmatch\"),\n ]
