How I can add button to the variants tab in the products screen in Odoo

Question

I try to add a button in the products screen but I can't find the correct path, and I do not know the problem.

this is my code

        <xpath expr="//page[@name='variants']" position="inside">
            <button string="Custom Button" type="object" name="custom_button_method"/>
        </xpath>

==========================================

but it gives an error

Element '<xpath expr="//page[@name=&#39;variants&#39;]">' cannot be located in parent view

Can anyone help me?

Answer 1

Inherit from the view that adds the variant page to force Odoo to resolve the parent view before applying the xpath.

Example:

<record id="product_template_form_extend" model="ir.ui.view">
    <field name="name">product.template.form.extend</field>
    <field name="model">product.template</field>
    <field name="inherit_id" ref="product.product_template_only_form_view"/>
    <field name="arch" type="xml">
        <xpath expr="//page[@name='variants']" position="inside">
            <button string="Custom Button" type="object" name="custom_button_method"/>
        </xpath>
    </field>
</record>
