The default behaviour is to display a list of addresses from the users's address book, from which the user can choose one to be their shipping address. They can add/edit/delete these USER addresses. This address will be automatically converted into a SHIPPING address when the user checks out. Alternatively, the user can enter a SHIPPING address directly which will be saved in the session and later saved as ShippingAddress model when the order is successfully submitted. z$oscar/checkout/shipping_address.htmlzcheckout:shipping-methodr$r%check_user_email_is_capturedZ$skip_unless_basket_requires_shippingcCsN|j}|rJ|}ytjj|dd|d<Wntjk rHYnX|S)NZ country_id)Z iso_3166_1_a2Zcountry)r8Znew_shipping_address_fieldscopyr"Zobjectsr.pop DoesNotExist)r/r6r3r3r4 get_initials zShippingAddressView.get_initialc s(tjf|}|jjjr$||d<|S)N addresses)r-get_context_datar'r(r)get_available_addresses)r/r1ctx)r2r3r4rPs  z$ShippingAddressView.get_context_datacCs|jjjjdddS)NT)Zcountry__is_shipping_countryz-is_default_for_shipping)r'r(rOfilterZorder_by)r/r3r3r4rQs z+ShippingAddressView.get_available_addressescs|jjjrld|jjkrltjj|jjd|jjd}|jjdd}|dkrb|j|t | St Snt j|f||SdS)NZ address_id)pkr(actionZship_to)r'r(r)POSTr!_default_managerr.r8Zship_to_user_addressrr>rHttpResponseBadRequestr-post)r/r'r0r1r rU)r2r3r4rYs     zShippingAddressView.postcs2tdd|jjD}|j|t|S)Ncss$|]\}}|ds||fVqdS)r<N) startswith).0kvr3r3r4 sz1ShippingAddressView.form_valid..)dictinstance__dict__itemsr8Zship_to_new_addressr-r@)r/r?Zaddress_fields)r2r3r4r@s zShippingAddressView.form_valid)rArBrCrDrErrFr r=rGskip_conditionsrNrPrQrYr@rHr3r3)r2r4rIns   rIcsDeZdZdZdZeZedZddZ fddZ fdd Z Z S) UserAddressUpdateViewz Update a user address z%oscar/checkout/user_address_form.htmlzcheckout:shipping-addresscCs|jjjS)N)r'r(rOall)r/r3r3r4 get_querysetsz"UserAddressUpdateView.get_querysetcst}|jj|d<|S)Nr()r-r7r'r()r/r1)r2r3r4r7s  z%UserAddressUpdateView.get_form_kwargscst|jtdtS)Nz Address saved)rr;r'r<r-r>)r/)r2r3r4r>sz%UserAddressUpdateView.get_success_url) rArBrCrDrErrFr r=rfr7r>rHr3r3)r2r4rds rdcs4eZdZdZdZedZddZfddZZ S)UserAddressDeleteViewz7 Delete an address from a user's address book. z'oscar/checkout/user_address_delete.htmlzcheckout:shipping-addresscCs|jjjS)N)r'r(rOre)r/r3r3r4rfsz"UserAddressDeleteView.get_querysetcst|jtdtS)NzAddress deleted)rr;r'r<r-r>)r/)r2r3r4r>sz%UserAddressDeleteView.get_success_url) rArBrCrDrEr r=rfr>rHr3r3)r2r4rgs rgcseZdZdZdZeZdddgZedZ fddZ fd d Z fd d Z fd dZ ddZddZfddZddZZS)ShippingMethodViewa View for allowing a user to choose a shipping method. Shipping methods are largely domain-specific and so this view will commonly need to be subclassed and customised.

This view class is used by two separate URLs: 'payment-details' and 'preview'. The `preview` class attribute is used to distinguish which is being used. Chronologically, `payment-details` (preview=False) comes before `preview` (preview=True). If sensitive details are required (e.g. a bankcard), then the payment details view should submit to the preview URL and a custom implementation of `validate_payment_submission` should be provided. - If the form data is valid, then the preview template can be rendered with the payment-details forms re-rendered within a hidden div so they can be re-submitted when the 'place order' button is clicked. This avoids having to write sensitive data to disk anywhere during the process. This can be done by calling `render_preview`, passing in the extra template context vars. - If the form data is invalid, then the payment details templates needs to be re-rendered with the relevant error messages. This can be done by calling `render_payment_details`, passing in the form instances to pass to the templates. The class is deliberately split into fine-grained methods, responsible for only one thing. This is to make it easier to subclass and override just one component of functionality. All projects will need to subclass and customise this class as no payment is taken by default. z#oscar/checkout/payment_details.htmlzoscar/checkout/preview.htmlr$r%rJrtFcs|jr|jdgSt|S)NZcheck_payment_data_is_captured)previewrGr-get_pre_conditions)r/r')r2r3r4rys z%PaymentDetailsView.get_pre_conditionscs|js dgSt|S)Nru)rxr-get_skip_conditions)r/r')r2r3r4rzsz&PaymentDetailsView.get_skip_conditionscOs4|jstS|jdddkr*||S||S)NrUZ place_order)rxrrXrVr.handle_place_order_submission!handle_payment_details_submission)r/r'r0r1r3r3r4rYs  zPaymentDetailsView.postcCs|jf|S)a Handle a request to place an order. This method is normally called after the customer has clicked "place order" on the preview page.

The process runs as follows: * Generate an order number * Freeze the basket so it cannot be modified any more (important when redirecting the user to another site for payment as it prevents the basket being manipulated during the payment process). * Attempt to take payment for the order - If payment is successful, place the order - If a redirect is required (e.g. PayPal, 3D Secure), redirect - If payment is unsuccessful, show an appropriate error message :basket: The basket to submit. :payment_kwargs: Additional kwargs to pass to the handle_payment method.
