Hello all,

On the product.template kanban view, for each product, I see all default_code of the associated variants.

If I click on one of this code, an empty form view opens instead of the form view of the clicked variant.

How could I open the form view with the right variant id?

I have tried passing the variant.id with the context, but I don't manage it.

Should I declared my action in PYthon instead of XML?

XML of the kanban and the action when we click a code :

<record id="product_variant_action_2" model="ir.actions.act_window">
            <field name="name">Product Variants</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">product.product</field>
            <field name="view_mode">form</field>
            <field name="view_type">form</field>
<!--         <field name="res_id" eval="context.get('res_id')"/>-->
            <field name="context">{}</field>
            <field name="search_view_id" ref="product.product_search_form_view"/>
            <field name="view_id" eval="False"/> <!-- Force empty -->
            <field name="domain" eval="False"/> <!-- Force empty -->
        </record>

        <record id="product_template_kanban_view_inherited" model="ir.ui.view">
            <field name="name">Product.template.kanban.view.inherited</field>
            <field name="model">product.template</field>
            <field name="inherit_id" ref="product.product_template_kanban_view" />
            <field name="arch" type="xml">
                <xpath expr="//div[@name='tags']" position="after">
                     <t t-foreach="record.product_variant_ids.raw_value" t-as="variant">
                        <a name="%(product_variant_action_2)d" context="{'res_id': variant.id}" 
                            type="action">[<t t-esc="variant.default_code"/>]</a>
                    </t>
                </xpath>
            </field>
         </record>

EDIT #1

I have defined a new python method to open my product variant in the current window. It takes the res_id from the context.

With this code, it opens the product variant id 1362 in a new form view. So my action works well :

<field name="arch" type="xml">
                <xpath expr="//div[@name='tags']" position="after">
                     <t t-foreach="record.product_variant_ids.raw_value" t-as="variant">
                        <a name="open_product_variant" context="{'res_id': 1362}" type="object">[<t t-esc="variant.id"/>
                           <t t-esc="variant.default_code"/>]</a>
                    </t>
                </xpath>
            </field>

With this code, what I would want, I get an error :

<field name="arch" type="xml">
                <xpath expr="//div[@name='tags']" position="after">
                     <t t-foreach="record.product_variant_ids.raw_value" t-as="variant">
                        <a name="open_product_variant" context="{'res_id': variant.id}" type="object">[<t t-esc="variant.id"/>
                           <t t-esc="variant.default_code"/>]</a>
                    </t>
                </xpath>
            </field>

I get this error :

Error: NameError: name 'variant' is not defined
