# ERROR FIX REPORT - product_price_category_supplier

**Date**: 10 de febrero de 2026
**Status**: ✅ FIXED & VERIFIED
**Author**: GitHub Copilot

---

## Summary

El addon tenía 2 categorías de errores que fueron corregidos exitosamente:

1. **Error crítico**: XPath incorrecto en vista XML
2. **Warnings**: Uso de `_()` en definiciones de campos de modelo

**Current Status**: ✅ Addon instalado correctamente en Odoo

---

## Errors Found & Fixed

### 1. ParseError: XPath not found in parent view

**Error Message**:
```
odoo.tools.convert.ParseError: while parsing /mnt/extra-addons/product_price_category_supplier/views/res_partner_views.xml:4
Error while parsing or validating view:
Element '<xpath expr="//notebook/page[@name='purchase']">' cannot be located in parent view
```

**Root Cause**:
- La vista base del partner en Odoo 18.0 no tiene una página con name='purchase'
- La estructura real usa `sales_purchases` para la página que contiene campos de ventas y compras
- El XPath buscaba la estructura incorrecta

**Solution Applied**:

#### File: `views/res_partner_views.xml`

**Change 1 - Form View (Line 11)**:
```diff
- <xpath expr="//notebook/page[@name='purchase']" position="inside">
+ <xpath expr="//page[@name='sales_purchases']" position="inside">
```

**Change 2 - Tree View (Line 27)**:
```diff
- <field name="name" position="after">
+ <field name="complete_name" position="after">
```

**Reason**: El tree view de partner usa `<list>` (no `<tree>`) con `complete_name` como primer campo, no `name`.

---

### 2. Translation Warning - "_() in field definitions at import time"

**Warning Message**:
```
2026-02-10 16:17:56,165 47 WARNING odoo odoo.tools.translate: no translation language detected,
skipping translation <frame at ..., file '...wizard_update_product_category.py', line 21, code WizardUpdateProductCategory>
```

**Root Cause**:
- Uso de `_()` en definiciones de campos de modelo durante la importación del módulo
- En Odoo, cuando los módulos se cargan, el contexto de traducción no está disponible aún
- Los strings en definiciones de campos se extraen automáticamente por Odoo sin necesidad de `_()`

**Solution Applied**:

#### File: `models/res_partner.py` (Lines 13-15)

```diff
  default_price_category_id = fields.Many2one(
      comodel_name='product.price.category',
-     string=_('Default Price Category'),
-     help=_('Default price category for products from this supplier'),
+     string='Default Price Category',
+     help='Default price category for products from this supplier',
      domain=[],
  )
```

#### File: `models/wizard_update_product_category.py` (Lines 15, 21, 27, 34)

```diff
  partner_id = fields.Many2one(
      comodel_name='res.partner',
-     string=_('Supplier'),
+     string='Supplier',
      readonly=True,
      required=True,
  )

  partner_name = fields.Char(
-     string=_('Supplier Name'),
+     string='Supplier Name',
      readonly=True,
      related='partner_id.name',
  )

  price_category_id = fields.Many2one(
      comodel_name='product.price.category',
-     string=_('Price Category'),
+     string='Price Category',
      readonly=True,
      required=True,
  )

  product_count = fields.Integer(
-     string=_('Number of Products'),
+     string='Number of Products',
      readonly=True,
      required=True,
  )
```

**Why This Works**:
- Odoo's translation extraction system automatically captures field `string` and `help` values
- No necesita marcador `_()` - se extrae durante la compilación del módulo
- Evita warnings de "no translation language detected"
- Los strings siguen siendo traducibles en archivos .po

## Verification Results

### ✅ Installation Success

✅ No errors
✅ No critical warnings

```

### Database Changes Applied

- ✅ Table `wizard_update_product_category` created
- ✅ Field `default_price_category_id` added to `res_partner`
- ✅ View records created in `ir.ui.view`
- ✅ Security ACL created in `ir.model.access`

---

## Files Modified

| File | Changes | Status |
|------|---------|--------|
| `views/res_partner_views.xml` | XPath corrected (2 changes) | ✅ Fixed |
| `models/res_partner.py` | `_()` removed from field definition (1 change) | ✅ Fixed |
| `models/wizard_update_product_category.py` | `_()` removed from 4 field definitions | ✅ Fixed |

---

## What Was NOT Changed

❌ Translation strings WERE NOT removed from:
- Python code logic (methods still use `_()` for user-facing messages)
- View templates (unchanged - Odoo extracts them automatically)
- XML button labels and help text (extracted by Odoo)

The fix only removed `_()` from **field definition string/help parameters**, where translation happens at extraction time, not at runtime.

---

## Testing Recommendations

### 1. Verify Field Appears in UI

```
1. Go to Contacts (Contactos)
2. Select a supplier (supplier_rank > 0)
3. Open "Sales & Purchase" tab
4. Should see "Price Category Settings" group with:
   - "Default Price Category" field
   - "Apply to All Products" button
```

### 2. Test Bulk Update Functionality

```
1. Create a price category (e.g., "Premium")
2. Select supplier with products
3. Set supplier's "Default Price Category" to "Premium"
4. Click "Apply to All Products"
5. Confirm in wizard modal
6. Verify products updated in product list
```

### 3. Test Translations

```
1. User preferences → Change Language to Spanish (es)
2. Verify labels display in Spanish:
   - "Categoría de Precio Predeterminada"
   - "Aplicar a Todos los Productos"
3. Repeat for Euskera (eu)
```

### 4. Verify Permissions

```
1. Test with sales_team.group_sale_manager → Should have access ✅
2. Test with basic user → Should not see wizard access ✅
```

## Architecture Notes

### Odoo 18.0 Partner Form Structure

The corrected XPath path now properly targets:
```xml
<record id="view_partner_form" model="ir.ui.view">
    <field name="arch" type="xml">
        <form>
            <notebook>
                <page name="contact_addresses">...</page>
                <page name="sales_purchases">  ← We insert here
                    ...existing fields...
                </page>
                <page name="internal_notes">...</page>
            </notebook>
        </form>
    </field>
</record>
```

### Tree View Structure (List in Odoo 18)

```xml
<record id="view_partner_tree" model="ir.ui.view">
    <field name="arch" type="xml">
        <list>
            <field name="complete_name">  ← First field (was: name)
            <field name="default_price_category_id" column_invisible="1"/>  ← We add after
            ...
        </list>
    </field>
</record>
```
