Hi! 

I'm trying to show data from product_template model on a custom addon, but I'm facing that error. Why? What I'm doing wrong? 

Here is part of my Model code : 

class tienda(models.Model):

_name="tienda.tienda"

_auto= False

_description="Gestion de tienda"

product = fields.Many2one('product.template')

name= fields.Char(string="Producto", related="product.name")

And Here is my view 

<record id="action_tienda_tree" model="ir.ui.view">

<field name="name">tienda.tienda.tree</field>

<field name="model">tienda.tienda</field>

<field name="arch" type="xml">

<tree>

<field name="producto" />

</tree>

</record>

</field>

And the error says : "KeyError: 'Field name referenced in related field definition tienda.tienda.name does not exist.'"

Thanks for the explanation.
