django-pgfields 1.4

Welcome to django-pgfields 1.4!

Overview

This release builds on django-pgfields by adding support for requiring a specific type on JSONField, and for allowing arbitrary callables for generating UUIDs automatically on UUIDField.

Features

• The JSONField class now allows you to send a type argument, along with a class that is JSON serializable, such as dict or list. Use this to require that the root value of a JSONField always be a particular type.
• The UUIDField class now accepts a callable as the value of auto_add (sending True still works). If specified, this callable will be used to generate new UUIDs. Any callable that takes no arguments and reliably returns a UUID is acceptable.

Minor Releases

• As of 1.4.2, django-pgfields ships with a DateTimeField subclass that accepts UNIX timestamps as values (and otherwise behaves exactly like its parent, the stock Django class).
• As of 1.4.3, sending a query to an ArrayField with a __len and value of 0 works. This was broken in prior releases because it requires special query handling in PostgreSQL (which expects a NULL value).
