Hi community,

I tried in odoo 10 to create a view but I have an error when i'm trying to upgrade my module.

Here my view 

<odoo>
    <data>
         <record id="view_address_referencial_tree" model="ir.ui.view">
            <field name="name">upecom.address.referencial.tree</field>
            <field name="model">upecom.address.referencial</field>
            <field name="arch" type="xml">
                <tree string="Address">
                    <field name="country_id"/>
                    <field name="city"/>
                </tree>
            </field>
        </record>
        <record id="view_address_referencial_search" model="ir.ui.view">
            <field name="name">upecom.address.referencial.search</field>
            <field name="model">upecom.address.referencial</field>
            <field name="arch" type="xml">
                <search string="Address">
                    <field name="city"/>
                    <field name="postal_code"/>
                </search>
            </field>
        </record>
        <record id="view_address_referencial_form" model="ir.ui.view">
            <field name="name">upecom.address.referencial.form</field>
            <field name="model">upecom.address.referencial</field>
            <field name="arch" type="xml">
                <form string="Address">
                    <group>
                        <field name="city"/>
                        <field name="postal_code"/>
                     </group>
                </form>
            </field>
        </record>
        <record id="action_address_referencial_form" model="ir.actions.act_window">
            <field name="name">Address Referencial</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">upecom.address.referencial</field>
            <field name="view_type">form</field>
            <field name="view_mode">tree,form</field>
            <field name="help" type="html">
                <p class="oe_view_nocontent_create">
                    Click to define a new postal code.
                </p>
            </field>
        </record>
        <menuitem name="toto" action="action_address_referencial_form" id="menu_action_address_referencial_form" parent="delivery.sale_menu_delivery"
                  sequence="1"/>
    </data>
</odoo>

Here my model

class AddressReferencial(models.Model):
    _name = "upecom.address.referencial"
    city = fields.Char("City")
    postal_code = fields.Char("Postal Code", index=True)
    country_id = fields.Many2one(
        'res.country', required=True, ondelete='cascade',
        string="Country"
  )

And the error message is : 

Model not found : upecom.address.referencial

Context of the error :
View `upecom.address.referencial.tree`

                </tree>
            </field>
        </record>

If somebody can help me to fix this ? 

Thanks
