# Changelog - Website Sale Aplicoop

## [18.0.1.9.0] - 2026-05-20

### Added

- **Category sequence**: New `sequence` field on `product.category` for controlling product display order on the web shop. Migration adds the column with default 10.
- **Stock availability check on history orders**: When loading a historical order, products are validated against current stock (`virtual_available`). Out-of-stock items are flagged before adding to cart.

### Changed

- **Cart disabled / redirected to /eskaera**: Standard `website_sale` cart is fully hidden — header cart icon removed, add-to-cart buttons removed from standard shop, `/cart` and `/shop` routes redirect to `/eskaera`. Customers interact exclusively through the group order flow.
- **Product card UI overhaul**: Improved responsive layout, placeholder image for products without photo, better accessibility markup, and professional styling for mobile.
- **Stock check uses `virtual_available`**: Replaces `qty_available` so forecasted quantity (including incoming moves) is considered.

### Fixed

- Lint fixes: exception chaining (`raise ... from exc`), unused imports/vars, `disable attribute-string-redundant` annotations.

## [18.0.1.8.0] - 2026-04-08

### Added

- **Clear cart button**: New button in the sidebar to empty the current group order cart in one click (`eskaera_clear_cart` route).

### Changed

- **Portal access restricted to consumer group**: Portal users can only see group orders belonging to their consumer group. Security rule `rule_group_order_company_read` updated with `user.share` guard.
- **Controller filtering by consumer group**: `eskaera_list` and `eskaera_shop` routes filter orders by the logged-in user's consumer group, not just by company.

### Fixed

- Stale cart invalidation: carts linked to closed/cancelled group orders are cleared on next access.
- Home delivery draft flow: fixed state transition for home delivery orders.
- Auto-confirm `sale.order` on cutoff day: fixed off-by-one (`>` vs `>=`) in cutoff guard so orders on the cutoff day are correctly confirmed.
- Pickup dates frozen after cron confirm: cron no longer overwrites pickup dates on already-confirmed orders.
- Cron hardened against missing/invalid group order configurations.
- Cart layout: moved cart sidebar before product grid.
- i18n: added missing ES/EU translations for checkout, cart labels, Save Draft button, and weekday strings. Removed legacy `week_draft` translation keys.

---

## [18.0.1.7.0] - 2026-03-06

### Added

- **Automatic batch picking creation**: After the cutoff cron confirms sale orders, picking batches are automatically created grouped by consumer group and pickup date.
- **Consumer group propagation**: `consumer_group_id` is now propagated directly from the `group.order` to linked `sale.order` records, eliminating manual assignment.
- **Out-of-stock blocking**: Add-to-cart button is hard-disabled for out-of-stock products. `allow_out_of_stock_order` flag on product is respected.

### Changed

- **Cron auto-confirm sale orders**: Daily cron (`_cron_confirm_group_orders`) now confirms linked sale orders on the cutoff date instead of requiring manual action.
- **Order card meta extracted**: Order card metadata (dates, state badge) moved to a reusable `_eskaera_order_card_meta` template for cleaner rendering.
- Delivery toggle (reparto/envío a domicilio) wired directly from the cart sidebar.
- Pricing alignment: theoretical price and displayed price reconciled for orders with home delivery.

### Fixed

- Fixed broken `aplicoopShop` → `groupOrderShop` JS class reference.
- Ensured add-to-cart event listeners are re-attached after infinite scroll loads new products.
- i18n: translated weekday names (ES/EU).

## [18.0.1.6.0] - 2026-02-22

### Added

- **Category Blacklist Feature**: Category-based exclusion system for group orders
  - New field: `excluded_category_ids` (Many2many to product.category)
  - Recursive exclusion: Excludes products in selected categories AND all subcategories
  - Blacklist has absolute priority over all inclusion sources
  - Helper method: `get_all_excluded_descendants()` for recursive category tree traversal
  - Comprehensive test suite in `test_product_discovery.py` (TestCategoryBlacklist class with 9 tests)

### Changed

- **Product Discovery Logic**: Extended to filter by category blacklist
  - `_get_products_for_group_order()` now applies `excluded_category_ids` filter recursively
  - Products in excluded categories and their subcategories are filtered out
  - `_compute_available_products_count()` now depends on `excluded_category_ids`
  - Detailed logging for excluded categories and affected products

- **UI Updates**: "Productos Excluidos" section now includes three blacklist types:
  - `excluded_supplier_ids`: Blacklist suppliers
  - `excluded_category_ids`: Blacklist categories (recursive)
  - `excluded_product_ids`: Blacklist specific products

### Technical Details

- New M2M relation: `group_order_excluded_category_rel`
- Recursive logic: Walks category tree to find all descendants
- Filter logic: `products.filtered(lambda p: p.categ_id not in all_excluded_categories)`
- Works in combination with product and supplier blacklists (all filters apply)

### Use Case

- Admin wants to exclude all products in a category and its subcategories
- Example: Exclude "Fresh Produce" → automatically excludes "Fruits", "Vegetables", etc.
- Add parent category to inclusion → add problematic subcategory to exclusion
- Result: Fine-grained control over product catalog with minimal configuration

## [18.0.1.5.0] - 2026-02-22

### Added

- **Supplier Blacklist Feature**: New exclusion system by supplier for group orders
  - New field: `excluded_supplier_ids` (Many2many to res.partner)
  - Filters products by `main_seller_id` (from product_main_seller addon)
  - Blacklist has absolute priority over all inclusion sources
  - Products whose main supplier is blacklisted never appear
  - Comprehensive test suite in `test_product_discovery.py` (TestSupplierBlacklist class with 9 tests)

### Changed

- **Product Discovery Logic**: Extended to filter by supplier blacklist
  - `_get_products_for_group_order()` now applies `excluded_supplier_ids` filter
  - Products with `main_seller_id` in excluded_supplier_ids are filtered out
  - `_compute_available_products_count()` now depends on `excluded_supplier_ids`
  - Detailed logging for excluded suppliers and affected products

- **UI Updates**: "Productos Excluidos" section now includes both:
  - `excluded_supplier_ids`: Blacklist suppliers
  - `excluded_product_ids`: Blacklist specific products

### Technical Details

- New M2M relation: `group_order_excluded_supplier_rel`
- Filter logic: `products.filtered(lambda p: p.product_tmpl_id.main_seller_id not in excluded_supplier_ids)`
- Works in combination with product blacklist (both filters apply)
- Uses `main_seller_id` from product_main_seller addon (NOT default_supplier_id)

### Use Case

- Admin wants to exclude all products from a specific supplier (e.g., temporary unavailability)
- Add category with 100 products → add problematic supplier to excluded_supplier_ids
- Result: All products from that supplier are excluded, even if directly included
- Combined workflow: Category inclusion + supplier exclusion + individual product exclusion

## [18.0.1.4.0] - 2026-02-22

### Added

- **Product Blacklist Feature**: New exclusion system for group orders
  - New field: `excluded_product_ids` (Many2many to product.product)
  - Blacklist has absolute priority over all inclusion sources (product_ids, category_ids, supplier_ids)
  - Model method: Updated `_get_products_for_group_order()` with blacklist filter
  - Comprehensive test suite in `test_product_discovery.py` (TestProductBlacklist class)

### Changed
- **UI Improvements**: Renamed "Associations" section to "Catálogo de Productos" for better user clarity
  - New subsection: "Productos Incluidos" (whitelist: suppliers, categories, direct products)
  - New subsection: "Productos Excluidos" (blacklist: explicit exclusions)
  - Updated help texts for all inclusion fields
  - Complete Spanish and Euskera translations

- **Product Discovery Logic**:
  - `_get_products_for_group_order()` now applies `excluded_product_ids` filter at the end
  - Products in blacklist never appear, regardless of inclusion source
  - `_compute_available_products_count()` now depends on `excluded_product_ids`
  - Detailed logging for excluded product count

### Technical Details
- New M2M relation: `group_order_excluded_product_rel` (separate from whitelist relations)
- Blacklist filter uses set subtraction: `products = products - order.excluded_product_ids`
- All tests validate absolute priority: direct products, category products, supplier products, and multi-source products all respect blacklist

### Use Case
- Admin selects a category with 100 products → adds to category_ids
- Admin identifies 5 unwanted products → adds to excluded_product_ids
- Result: 95 products available in the order
- Workflow: Bulk inclusion via categories/suppliers + fine-grained exclusion via blacklist

## [18.0.1.3.0] - 2026-02-16

### Added

  - Re-attaches listeners after AJAX loads new products

- README.md:
  - Added lazy loading feature to features list
  - Added version 18.0.1.3.0 to changelog

### Performance Impact
- **Initial page load**: 10-20s → 500-800ms (20x faster)
- **Product DOM size**: 1000 elements → 20 elements (initial)
- **Subsequent page loads**: 200-400ms via AJAX
- **Price calculation**: Only for visible products (reduced from 1000+ to 20)

### Technical Details
