release:2018-05-23

Welcome to Oscar 1.6

Table of contents:

Compatibility

Oscar 1.6 is compatible with Django 1.11 and Django 2.0 as well as Python 2.7, 3.4, 3.5 and 3.6.

Official support for Django 1.8, 1.9 and 1.10 has been dropped.

What’s new in Oscar 1.6?

  • Added support for managing large amounts of vouchers grouped in sets.

Removal of deprecated features

  • oscar.core.phonenumber.PhoneNumber is removed. Use phonenumber_field.phonenumber.PhoneNumber instead.
  • Removed the redundant OSCAR_PROMOTION_MERCHANDISING_BLOCK_TYPES setting.

Minor changes

  • The majority of the Oscar class imports now use dynamic loading, instead of direct imports, for better extensibility and customisability.
  • Added the ability to specify a custom class loader through the OSCAR_DYNAMIC_CLASS_LOADER setting.
  • Customer transaction emails were reworked to use Mailgun templates, so that they have a more modern appearance.
  • SearchHandler.get_search_form method now accepts additional keyword arguments, which will be passed on search form class instance.
  • Added get_stock_info hook to oscar.apps.basket.models.Basket for implementing strategies that depend on product options.
  • Fixed the page create/update views in the dashboard to correctly validate URLs. Invalid characters in URLs will raise a validation error, as will URLs longer than 100 characters.
  • The default shipping method ( oscar.apps.basket.views.BasketView.get_default_shipping_address) on the basket summary page now uses the user’s default shipping address to calculate an indicative shipping cost.
  • Fixed ExtendedURLValidator for locale-prefixed URLs for locales, different from current (see #1481). Previously, validation did not pass when if the current locale was “en-gb” and, the a visited URL was “/de/catalogue/” and visa versa due to Django’s default behaviour.
  • Product attribute value save is now handled by separate methods, to make it
    easier to override this behaviour.
  • Address hash generation is now separated from the summary in order to preserve same behavior when summary property customized (see #1537). They can use different field names, listed out in base_fields and hash_fields respectively. Also hash generation now became platform-independent and generates the same for Python 2 and 3. Corresponding data migration will update hashes automatically. Take it into account that it will take time to run if you have large user base.
  • Compact basket form is no longer displayed for the products with options on product list pages since it caused form elements to impose inside the product box (see :issues:`1976`).
  • Added has_options property to the oscar.apps.catalogue.models.Product model to indicate whether an instance or its product class has product options.
  • oscar.core.validators.validate_password was removed. Use django.contrib.auth.password_validation.validate_password instead.
  • oscar.core.validators.CommonPasswordValidator was removed. Use django.contrib.auth.password_validation.CommonPasswordValidator instead.
  • User notifications are marked as read only when viewed in detail, instead of being marked as read in bulk when the notification list was viewed.
  • Oscar’s ImageInput, TimePickerInput, DatePickerInput and DateTimePickerInput all use templates for rendering.
  • It is now possible to manage images for variant products and their parents.
  • For variant products we now display their own images on product detail page and fallback to parent product images if they don’t have any.
  • Basket line form quantity field now has “max” attribute with the maximum allowed quantity in it based on product availability and basket threshold (see #1412).
  • An unused setting OSCAR_SETTINGS was removed from oscar.core.defaults.
  • Fixed ``PhoneNumberMixin``s handling of empty phone number fields in forms.

Backwards incompatible changes in Oscar 1.6

  • Fixed a regression introduced in Oscar 1.5 (see #2664) where StockRequired.availability_policy was dependent on the product having a price. Price and availability are now decoupled, and it is possible to defer determination of a price until a product is added to the basket.
  • oscar.apps.customer.auth_backends.EmailBackend now rejects inactive users (where User.is_active is False).
  • EmailBackend no longer enforces its own password strength validation, and relies instead on the AUTH_PASSWORD_VALIDATORS setting used by Django.
  • oscar.apps.basket.middleware.BasketMiddleware was rewritten as new-style middleware for Django 1.11.
  • oscar.apps.offer.models.ConditionalOffer now has a new flag exclusive to denote that the offer involved can not be combined on the same item on the same basket line with another offer. This flag is used by oscar.apps.basket.utils.LineOfferConsumer, a facade that supercedes the old oscar.apps.basket.models.Line._affected_items counter, and replaces it with a more finegrained approach. This makes it possible to apply two distinct non-exclusive offers on the same basketline items, for example multiple distinct vouchers. A couple of methods on the basketline model have been extended with an optional offer argument, i.e. discount and consume, so if you are using a customized basketline model, you have to update your methods’ signatures.
  • Invalid URL names supplied to the OSCAR_DASHBOARD_NAVIGATION setting are now logged as an exception (previously they were silently ignored). The offending menu item will be skipped during menu rendering. In Oscar 1.8 the exception will be raised without being intercepted.
  • All signals are now loaded directly rather than using dynamic imports.
  • Stock manipulation (allocation/consumption/cancellation) now only happens if the track_stock property of the product’s class is set to true.
  • oscar.forms.widgets.RemoteSelect was updated to work with version 4 of select2. Instead of rendering a hidden input it now renders a normal select element.
  • The django-extra-views dependency was upgraded to version 0.11, and the basket views that rely on extra_views.ModelFormSetView updated to use the new factory_kwargs attribute.
  • jQuery UI was removed from Oscar’s static files. Projects that require it should install it at the project level.
  • Compatibility for Internet Explorer version 9 an lower was dropped from Oscar’s templates and styles.
  • The Google Analytics tracking code provided by Oscar now uses gtag.js API instead of the deprecated analytics.js. Analytics are also disabled by default in Oscar’s dashboard.

Dependency changes

  • Upgraded jQuery to version 3.3.1.
  • Upgraded Bootstrap to version 3.3.7.
  • Upgraded bootstrap-datetimepicker to v2.4.4.
  • Upgraded jQuery-mousewheel to v3.1.13.
  • Upgraded inputmask to v3.2.7.
  • Upgraded jquery-sortable to v0.9.13.
  • Upgraded select2 to v4.0.5.
