postgres.fields.HStoreField

class HStoreField(**options) [source]

A field for storing mappings of strings to strings. The Python data type used is a dict.

To use this field, you’ll need to:

1. Add 'django.contrib.postgres' in your INSTALLED_APPS.

2. Setup the hstore extension in PostgreSQL before the first CreateModel or AddField operation by adding a migration with the HStoreExtension operation. For example:

   from django.contrib.postgres.operations import HStoreExtension
   
   class Migration(migrations.Migration):
       ...
   
       operations = [
           HStoreExtension(),
           ...
       ]
   

   Creating the extension requires a database user with superuser privileges. If the Django database user doesn’t have superuser privileges, you’ll have to create the extension outside of Django migrations with a user that has the appropriate privileges. In that case, connect to your Django database and run the query CREATE EXTENSION IF NOT EXISTS hstore;

You’ll see an error like can't adapt type 'dict' if you skip the first step, or type "hstore" does not exist if you skip the second.
