- Backend: Agregar método _validate_items_for_group_order() para validar que los productos históricos sigan siendo disponibles en la orden de grupo actual
- Backend: Modificar load_order_from_history() para filtrar solo items disponibles antes de pasar al template
- Backend: Generar mensaje de aviso traducido cuando hay productos no disponibles
- Template: Pasar información de productos no disponibles y warnings al JavaScript
- Frontend: Mostrar notificación de advertencia si hubo productos excluidos durante la carga histórica
- Notas: Esto evita cargar productos que ya no existen en la orden actual debido a cambios en categorías, proveedores o listas negras
Añade botón 'Clear Cart' (fa-trash) en el header y footer del sidebar
del carrito en la página de lista de productos.
Cambios:
- views/website_templates.xml: botón clear-cart-btn en card-header y
clear-cart-btn-footer en card-footer del sidebar
- controllers/website_sale.py: nuevo endpoint POST /eskaera/clear-cart
que cancela el sale.order borrador del usuario si existe
- static/src/js/website_sale.js: método _clearCart(), listeners para
ambos botones (header + footer)
- models/js_translations.py: nuevas cadenas clear_cart, clear_cart_confirm,
cart_cleared, draft_cancelled
- i18n/es.po, i18n/eu.po: traducciones ES y EU de los nuevos labels
The save-cart-btn event listener was placed after a return statement in
_attachEventListeners(), so it was never executed. Moved it to the correct
location inside the _cartCheckoutListenersAttached block alongside the
other cart/checkout buttons (reload-cart-btn, confirm-order-btn, etc.).
The _attachEventListeners() function was cloning the products-grid element
without its children (cloneNode(false)) to remove duplicate event listeners.
This destroyed all loaded products every time the function was called.
Solution: Use a flag (_delegationListenersAttached) to prevent adding
duplicate event listeners instead of cloning and replacing the grid node.
This fixes the issue where products would disappear ~1-2 seconds after
page load.
