Ajouter un champ à product.pricelist.item dans Odoo

Question

Je veux ajouter selection field comme ci-dessous:

class product_pricelist_item1(models.Model): 
    _inherit = 'product.pricelist.item' 

    x_type = fields.Selection(selection=[('sample', 'Sample'),('moq', 'MOQ'),('others', 'Others')],string="Choices") 

sous forme product.pricelist.item. Je vous écris du code XML comme ci-dessous:

 <record id="product_pricelist_item_form_view_with_code" model="ir.ui.view"> 
      <field name="name">product.pricelist.item.form</field> 
      <field name="model">product.pricelist.item</field> 
      <field name="inherit_id" ref="product.product_pricelist_item_form_view" /> 
      <field name="arch" type="xml"> 
       <field name="min_quantity" position="after"> 
        <field name="x_type"/> 
       </field> 
      </field> 
     </record> 

Mais quand je l'ouvre pricelist il me donne une erreur comme ceci:

Answer 1

Lors de l'extension d'un modèle, si vous voulez ajouter des valeurs possibles à un champ de sélection, vous pouvez utiliser l'argument mot-clé selection_add:

class SomeModel(models.Model): 
    _inherits = 'some.model' 
    type = fields.Selection(selection_add=[('b', 'B'), ('c', 'C')]) 

reference

Effectuez les opérations suivantes

class product_pricelist_item(models.Model): 
    _inherit='product.pricelist.item' 

    x_type= fields.Selection(selection_add=[('b', 'B')]) 

et xml

<record id='product_product_pricelist_item_form_view' model='ir.ui.view'> 
    <field name="model">product.pricelist.item</field> 
    <field name="inherit_id" ref="product.product_pricelist_item_form_view"/> 
    <field name="arch" type="xml"> 
     <form position="after"> 
     <field name="x_type" widget="radio"/> 
     </form> 
    </field> 
    </record> 

cela devrait fonctionner.
