- =========================
- Oscar 0.6.1 release notes
- =========================
-
- This is Oscar 0.6.1. It fixes one potentially serious data loss issue and a
- few minor bugs.
-
- Possible data loss from deleted users
- -------------------------------------
-
- Before this release, the foreign key from the
- :class:`~oscar.apps.order.abstract_models.Order` model to the ``User`` model
- did not specify an ``on_delete`` behaviour. The default is for deletes to
- cascade to related objects, even if the field is nullable. Hence, deleting a
- user would also delete any orders they had placed.
-
- As of 0.6.1, all foreign keys on the ``Order`` model specify
- ``on_delete=SET_NULL`` to avoid orders being deleted accidentally.
-
- See `Django's docs`_ for more info on ``on_delete`` options.
-
- Bug fixes
- =========
-
- The following bugs were fixed:
-
- * `#1128`_ - Calls to ``Source.debit`` without an ``amount`` argument were
- failing as ``balance`` was being called as a method instead of a property.
-
- * `#1130`_ - Variant products were not fetching the product class instance
- correctly within ``is_shipping_required``.
