- =========================
- How to configure shipping
- =========================
-
- Checkout flow
- -------------
-
- Oscar's checkout is set-up to follow the following steps:
-
- 1. Manage basket
- 2. Enter/choose shipping address
- 3. Choose shipping method
- 4. Choose payment method
- 5. Preview
- 6. Enter payment details and submit
-
- Determining the methods available to a user
- -------------------------------------------
-
- At the shipping method stage, we use a repository object to look up the
- shipping methods available to the user. These methods typically depend on:
-
- * the user in question (eg. staff get cheaper shipping rates)
- * the basket (eg. shipping is charged based on the weight of the basket)
- * the shipping address (eg. overseas shipping is more expensive)
-
- The default repository is ``oscar.apps.shipping.repository.Repository``, which
- has a method ``get_shipping_methods`` for returning all available methods. By
- default, the returned method will be ``oscar.apps.shipping.methods.Free``.
-
- Set a custom shipping methods
- -----------------------------
-
- To apply your domain logic for shipping, you will need to override
- the default repository class (see :doc:`how_to_override_a_core_class`) and alter
- the implementation of the ``get_shipping_methods`` method. This method
- should return a list of "shipping method" classes already instantiated
- and holding a reference to the basket instance.
-
- Building a custom shipping method
- ---------------------------------
-
- A shipping method class must define two methods::
-
- method.basket_charge_incl_tax()
- method.basket_charge_excl_tax()
-
- whose responsibilies should be clear. You can subclass ``oscar.apps.shipping.base.ShippingMethod``
- to provide the basic functionality.
-
- Built-in shipping methods
- -------------------------
-
- Oscar comes with several built-in shipping methods which are easy to use
- with a custom repository.
-
- * ``oscar.apps.shipping.methods.Free``. No shipping charges.
-
- * ``oscar.apps.shipping.methods.WeightBased``. This is a model-driven method
- that uses two models: ``WeightBased`` and ``WeightBand`` to provide charges
- for different weight bands. By default, the method will calculate the weight
- of a product by looking for a 'weight' attribute although this can be
- configured.
-
- * ``oscar.apps.shipping.methods.FixedPrice``. This simply charges a fixed price for
- shipping, irrespective of the basket contents.
-
- * ``oscar.apps.shipping.methods.OrderAndItemCharges``. This is a model which
- specifies a per-order and a per-item level charge.
