+Group orders (*eskaera*) are a business model for collaborative consumption where groups of users collectively purchase products within defined time windows. This module was created to replace the legacy Aplicoop application, providing:
+
+**Business Value:**
+- Streamlined group purchasing workflows within Odoo's standard sales framework
+- Flexible scheduling to accommodate different group shopping patterns (daily, weekly, biweekly, monthly)
+- Clear separation between temporary shopping carts and permanent sales orders
+- Support for multiple groups with different suppliers, products, and categories
+
+**Use Cases:**
+- Cooperative grocery purchasing groups
+- Bulk order consolidation for community members
+- Time-limited promotional campaigns with group participation
+- Multi-location organizations with shared procurement

+## [18.0.1.0.3] - 2025-12-19
+
+### Added
+- Centralised product discovery API on `group.order`: `_get_products_for_group_order(order_id)`.
+- Backward-compatible delegation on `product.product._get_products_for_group_order`.
+- Controller `AplicoopWebsiteSale` now delegates discovery to `group.order` and sanitises supplier display.
+
+### Changed
+- Moved discovery responsibility from `product.product` to `group.order` (single responsibility).
+- Updated `eskaera_shop`, `add_to_eskaera_cart` and `confirm_eskaera` to use centralised discovery.
+
+### Fixed
+- Avoided runtime AttributeError when discovery function was not present by providing a canonical implementation.
+- Ensured product discovery priority remains: explicit products → categories → suppliers.
+ - Fixed a regression where discovery returned only one association branch; discovery now
+	 returns the UNION of products from `product_ids`, `category_ids` and
+	 `supplier_ids` to avoid dropping valid products when multiple associations exist.
+
+	Note: this change documents and prevents a repeated mistake where a single
+	fallback branch hid products from other association fields.
+
+### Tests
+- `website_sale_aplicoop` test-suite: 63 tests, 0 failures after the refactor (commit 4b15207).
+
+### Security
+- Kept portal surface minimal (no `res.partner` records exposed); controller only injects supplier name/city for display.
+
+### I18N
+- Regenerated translation template (`.pot`) using an addon-only export to avoid collecting unrelated Odoo strings.
+- Added `docs/I18N_EXPORT_PITFALL.md` explaining the common export pitfall and safe export workflow (export to `/tmp`, restrict `--addons-path`, use `msgmerge`).
+- Added `tools/filter_pot_by_module.py` to filter POT files by module references and applied it to reduce the POT to addon-only entries (~168 entries).
+- Updated and committed cleaned `.po` files for all supported languages (es, pt, gl, ca, eu, fr, it).
+
+## [18.0.1.0.2] - 2025-12-14
+
+### Added
+- Multi-company support with company_id field on group.order
+- Company validation constraint to ensure groups belong to the same company
+- Multi-company filtering in get_active_orders_for_week() method
+- company_id field on res.partner for user-group relationships
+- 9 new test cases for multi-company scenarios (test_multi_company.py)
+- Post-migration script to assign default company to existing group.order records
+
+### Changed
+- group.order now respects allowed_company_ids context for data isolation
+- get_active_orders_for_week() filters by company context when applicable
+- group_ids domain now validates company relationships
+
+### Fixed
+- Ensured multi-company data isolation between different organizations
+
+## [18.0.1.0.1] - 2025-12-14
+
+### Added
+- Product discovery with 3-level fallback system (direct → categories → suppliers)
+- Search functionality by product name and description in eskaera_shop
+- Dynamic category filtering dropdown on shopping page
+- Product thumbnail images with fallback icons in base64 encoding
+- Comprehensive logging for debugging group order flow
+- Logging of cutoff day, pickup day, and order dates in eskaera_shop
+- 7 new test cases for product discovery scenarios (test_eskaera_shop.py)
+- Criptomart branding with logo.svg
+- Professional HTML documentation in static/description/index.html
+
+### Changed
+- Refactored product lookup to support three discovery methods
+- Updated confirm_eskaera to accept products from any discovery method
+- Improved error handling in checkout flow
+- Enhanced template rendering with conditional field validation
+- Optimized product search with regex and case-insensitive matching
+
+### Fixed
+- Fixed products not appearing when assigned via categories or suppliers (discovered via fallback)
+- Fixed translation errors in 7 languages (es, fr, ca, eu, gl, it, pt) - order type labels
+- Removed obsolete website_sale.py model file causing ImportError
+- Fixed checkout validation that blocked orders with category/supplier-discovered products
+- Fixed QWebException when start_date is optional by adding t-if validation
+- Fixed duplicate sale.order creation from double event binding on confirm button
+- Corrected product supplier relationship in tests (use seller_ids instead of supplier_id)
+
+### Deprecated
+- N/A
+
+### Removed
+- Obsolete models/website_sale.py file (functionality migrated to controllers)
+- Duplicate event listener on confirm button in website_templates.xml
+- Fallback confirmCheckout() function from template (handled by JS)
+
+### Security
+- Maintained CSRF protection on all POST routes
+- Input validation on JSON payloads in confirm_eskaera
+- Access control validation for group membership
+
+## [18.0.1.0.0-beta] - 2025-12-13
+

+# Seguridad y Control de Acceso - Website Sale Aplicoop
+
+## Descripción General
+
+El addon implementa un sistema completo de control de acceso basado en:
+1. **ACL (Access Control List)** - Permisos de lectura, escritura, creación y eliminación
+2. **Record Rules** - Filtros automáticos de registros por compañía
+3. **Grupos de Usuarios** - Roles con permisos específicos
+
+## Arquitectura de Seguridad
+
+```
+Usuario
+  ↓
+Grupo (group_group_order_user / group_group_order_manager)

+| `name` | Descripción |
+| `model_id:id` | Modelo que aplica la regla |
+| `groups:eval` | Grupo de usuarios (evaluado como Python) |
+| `domain_force` | Filtro dominio (sintaxis de búsqueda Odoo) |
+| `perm_read/write/create/unlink` | Permisos bajo esta regla |
+
+### Reglas Implementadas
+
+#### Rule 1: Usuarios Finales - Lectura por Compañía
+
+```csv
+rule_group_order_company_read,group.order: company access read,model_group_order,
+website_sale_aplicoop.group_group_order_user,"[('company_id', 'in', company_ids)]",1,0,0,0
+```
+
+**Dominio:** `[('company_id', 'in', company_ids)]`
+- `company_ids` = lista de compañías del usuario
+- Filtra automáticamente por compañía
+
+**Ejemplo:**
+```
+Usuario "Juan" pertenece a [Company A]
+Intenta ver órdenes
+Dominio aplicado: company_id IN (1)
+Resultado: Solo órdenes de Company A
+```
+
+#### Rule 2: Administradores - Lectura/Escritura por Compañía
+
+```csv
+rule_group_order_company_write,group.order: company access write,model_group_order,
+website_sale_aplicoop.group_group_order_manager,"[('company_id', 'in', company_ids)]",1,1,1,1
+```
+
+**Dominio:** `[('company_id', 'in', company_ids)]`
+- Igual que usuarios finales
+- Pero con permisos de escritura/creación
+
+**Ejemplo:**
+```
+Admin "Pedro" pertenece a [Company A, Company B]
+Crea nueva orden
+Dominio aplicado: company_id IN (1, 2)
+- Si crea en Company A: ✅ Permitido
+- Si crea en Company B: ✅ Permitido
+- Si intenta acceder a Company C: ❌ Denegado
+```
+
+#### Rule 3: Superusuarios - Acceso Global
+
+```csv
+rule_group_order_manager_global,group.order: manager global access,model_group_order,
+"['admin']","[]",1,1,1,1
+```
+
+**Grupo:** `['admin']` (Superusuario de Odoo)
+**Dominio:** `[]` (vacío = sin restricción)
+
+**Comportamiento:**
+- Acceso completo a todos los registros
+- Puede ver/editar órdenes de cualquier compañía
+- Sin filtrado por company_id
+
+## Flujo de Control de Acceso
+
+### Escenario 1: Usuario Final Lee Órdenes
+
+```
+1. Usuario "Maria" (group_group_order_user, Company A)
+2. Abre menú "Órdenes de Grupo"
+3. Odoo verifica:
+   a) ACL: ¿Tiene perm_read=1? → Sí (grupo_group_order_user)
+   b) Record Rule: ¿Cumple domain [('company_id', 'in', [1])]?
+      - Solo órdenes donde company_id = 1
+4. Resultado: Maria ve solo sus órdenes de Company A
+```
+
+### Escenario 2: Usuario Intenta Editar Orden
+
+```
+1. Usuario "Carlos" (group_group_order_user, Company A)
+2. Intenta editar orden de Company A
+3. Odoo verifica:
+   a) ACL: ¿Tiene perm_write=1? → No (grupo_group_order_user tiene 0)
+   b) Resultado: ❌ Acceso denegado - no puede editar
+```
+
+### Escenario 3: Admin Edita Orden de Otra Compañía
+
+```
+1. Admin "Rosa" (group_group_order_manager, Company A, B)
+2. Intenta editar orden de Company B
+3. Odoo verifica:
+   a) ACL: ¿Tiene perm_write=1? → Sí (grupo_group_order_manager)
+   b) Record Rule: ¿Cumple domain [('company_id', 'in', [1, 2])]?
+      - company_id de orden = 2
+      - 2 IN (1, 2) = Sí
+   c) Resultado: ✅ Rosa puede editar la orden
+```
+
+### Escenario 4: Superuser Accede a Todo
+
+```
+1. Admin "System" (superuser)
+2. Intenta editar cualquier orden de cualquier compañía
+3. Odoo verifica:
+   a) Es admin? → Sí
+   b) Rule: rule_group_order_manager_global aplica (domain = [])
+   c) Resultado: ✅ Acceso completo, sin restricciones
+```
+
+## Tests
+
+Archivo: [tests/test_record_rules.py](../tests/test_record_rules.py)
+
+### Casos de Prueba
+
+1. **test_user_company1_can_read_own_orders**
+   - Verifica que usuario de Company A ve sus órdenes
+
+2. **test_user_company1_cannot_read_company2_orders**
+   - Verifica que usuario NO ve órdenes de Company B
+
+3. **test_admin_can_read_all_orders**
+   - Verifica que admin con acceso a ambas compañías ve todo
+
+4. **test_user_cannot_write_other_company_order**
+   - Verifica que usuario no puede editar órdenes de otra compañía (AccessError)
+
+5. **test_record_rule_filters_search**
+   - Verifica que búsqueda automáticamente filtra por compañía
+
+6. **test_cross_company_access_denied**
+   - Verifica que acceso entre compañías es denegado
+
+7. **test_admin_can_bypass_company_restriction**
+   - Verifica que admin puede acceder a cualquier compañía
+
+### Ejecución
+
+```bash
+# Ejecutar solo tests de record rules
+odoo -d odoo -i website_sale_aplicoop -t website_sale_aplicoop.tests.test_record_rules --test-enable --stop-after-init
+
+# Con pytest
+pytest tests/test_record_rules.py -v
+```
+
+## Mejores Prácticas
+
+### ✅ Hacer
+
+1. **Confiar en ACL y Record Rules**
+   ```python
+   # Odoo filtra automáticamente
+   orders = env['group.order'].search([])
+   # Solo devuelve órdenes de compañía del usuario
+   ```
+
+2. **Usar grupos de seguridad correctamente**
+   ```xml
+   <!-- En vista XML -->
+   <group string="Administración" groups="website_sale_aplicoop.group_group_order_manager">
+       <button name="action_open" type="object" string="Open Order"/>
+   </group>
+   ```
+
+3. **Asignar compañías a usuarios**
+   ```python
+   user.write({
+       'company_id': company_a.id,
+       'company_ids': [(6, 0, [company_a.id, company_b.id])]
+   })
+   # El usuario ahora ve órdenes de A y B
+   ```
+
+### ❌ No Hacer
+
+1. **No usar sudo() sin razón válida**
+   ```python
+   # ❌ Malo - bypasea todas las restricciones
+   order = env['group.order'].sudo().search([])
+
+   # ✅ Bueno - respeta reglas
+   order = env['group.order'].search([])
+   ```
+
+2. **No modificar ACL directamente en SQL**
+   - Siempre use el CSV de datos
+
+3. **No olvidar agregar usuarios a grupos**
+   - Los usuarios deben estar en `group_group_order_user` o `group_group_order_manager`
+
+4. **No asumir permisos sin verificar**
+   - Siempre test con usuarios reales
+
+## Diagnóstico de Problemas
+
+### Problema: Usuario no ve ninguna orden
+
+**Causas posibles:**
+1. No está en grupo `group_group_order_user`
+2. No está asignado a la compañía correcta
+3. No existen órdenes en su compañía
+
+**Solución:**
+```python
+# Verificar grupo
+user.groups_id  # Debe incluir group_group_order_user
+
+# Verificar compañía
+user.company_ids  # Debe incluir la compañía del usuario
+
+# Verificar órdenes existentes
+env['group.order'].search([('company_id', '=', company_id)])
+```
+
+### Problema: Usuario no puede crear órdenes
+
+**Causas posibles:**
+1. Está en `group_group_order_user` (lectura solo)
+2. No tiene permiso `perm_create`
+
+**Solución:**
+```python
+# Mover a grupo de manager
+user.groups_id = [(3, group_order_user.id), (4, group_order_manager.id)]
+```
+
+### Problema: Error AccessError al leer orden
+
+**Causa probable:**
+- La orden está en una compañía diferente
+- Record rule está denegando acceso
+
+**Solución:**
+```python
+# Verificar compañía de orden
+order.company_id  # Comparar con user.company_ids
+```
+
+## Historial de Cambios
+
+### v18.0.1.0.2
+
+- ✨ Record rules agregadas para multicompañía
+- 🔒 ACL actualizado con documentación
+- 🧪 7 test cases para control de acceso
+- 📚 Documentación completa de seguridad

+
+## Cambios recientes y acciones realizadas (19-12-2025)
+
+Se documentan aquí las modificaciones y acciones realizadas durante la sesión de depuración y ejecución de tests:
+
+- **Regla interna `rule_group_order_user_company_read_internal`**: se actualizó el dominio de
+  `('company_id', '=', user.company_id.id)` a `('company_id', 'in', user.company_ids.ids)` para
+  soportar usuarios multi-compañía (por ejemplo, administradores creados en tests con
+  `company_ids` que contienen varias compañías). Esto permite que usuarios con varias
+  compañías vean las `group.order` pertenecientes a cualquiera de sus `company_ids`.
+
+- **Escape de entidades XML**: se corrigieron errores de parseo XML (p. ej. `xmlParseEntityRef: no name`)
+  reemplazando `&` por `&amp;` en los dominios de las reglas cuando era necesario.
+
+- **ACL temporal para triage de tests**: durante la depuración se añadió/ajustó una entrada mínima
+  en `security/ir.model.access.csv` (`access_group_order_base`) para permitir operaciones de prueba
+  (lectura/creación/edición según necesitaba el entorno de tests). Esta entrada se introdujo solo
+  para facilitar la ejecución de tests y validaciones locales; considerar revisarla antes de
+  publicar si se requiere endurecer los permisos.
+
+- **Ejecuciones de tests**:
+  - Módulo `website_sale_aplicoop`: ejecución local completada — `63 tests`, **0 fallos** para este módulo.
+  - Ejecución completa del conjunto de tests de Odoo: `3583 tests` ejecutados en total;
+    **34 fallos** y **65 errores** (log completo disponible en `/tmp/test_output_full_run.log`).
+
+- **Recomendaciones**:
+  - Si se desea completar la corrección de la suite completa, empezar triando las primeras
+    fallas del log (`grep -n "FAILED\|Traceback" /tmp/test_output_full_run.log | head -n 50`).
+  - Revisar la permanencia de `access_group_order_base` en `ir.model.access.csv` y ajustarla
+    para que los tests no hayan forzado permisos en producción.
+  - Mantener la regla que limita el acceso del portal a `product.supplierinfo` para no exponer
+    `res.partner` al portal; cualquier información adicional del proveedor debe inyectarse
+    desde los controladores de manera explícita y mínima.
+
+Esta sección se añadió para dejar constancia de los cambios que afectan a la política de acceso
+y a la ejecución de tests; actualizarla cuando se hagan revert/ajustes adicionales.

+## Creating a Group Order
+
+1. Go to **Website Sale > Group Orders > Create**
+2. Fill in the order details:
+   - **Order Name**: Descriptive name (e.g., "Weekly Vegetable Order")
+   - **Start Date**: When the order opens for shopping (leave empty for orders that are always open)
+   - **End Date**: When the order closes (optional; leave empty for permanent orders)
+   - **Cutoff Day**: Day of week when purchases stop (0=Monday, 6=Sunday) - mandatory
+   - **Recurrence Period**: How often the order repeats (once, weekly, biweekly, monthly)
+   - **Suppliers**: Link to product suppliers (informational)
+   - **Products**: Products available in this order (REQUIRED - add via the "Products" tab)
+   - **Categories**: Product categories available in this order (informational)
+   - **Groups**: Which user groups can participate (REQUIRED - users from these groups can shop)
+
+3. **Assign Products**: Click on the "Products" tab and add all products that should be available for this order
+4. Click **Save** and transition the order to **Open** state to allow shopping
+
+### Note on Start Date
+
+- If **Start Date is empty**, the order is considered always open (ignoring date range checks)
+- If **Start Date is set**, the order is only active starting from that date
+- Use empty Start Date for orders that should always be available during their time window
+
+## Shopping for a Group Order
+
+1. Navigate to the website storefront at `/eskaera` (group orders page)
+2. View active group orders for your participating groups
+3. Select an order to view available products
+4. Add products to your cart (separate cart per order)
+5. At checkout, confirm your order to convert items to a sales order draft
+6. Proceed through standard Odoo checkout workflow
+
+## Configuration
+
+### Managing Groups
+
+1. Go to **Contacts > Groups** (res.partner with is_group=True)
+2. Create groups for user communities
+3. Add partners/users to groups via the **Members** tab
+
+### Managing Products
+
+1. Products are linked to group orders via the **Group Orders** field in product settings
+2. Set pricing and availability per group order
+3. Assign products to categories used in group orders
+
+### Date & Time Validation
+
+- `start_date` must be ≤ `end_date` (when both filled)
+- Empty end_date = permanent order
+
