I am trying to edit the "default_code" field on the product.product model. I am attempting to make it so the field is no longer copied when duplicating a record. This is my XML record:
<record id="product.field_product_product_default_code" model="ir.model.fields">
<field name="copy" eval="False"/>
</record>
When I import the module, I can an error. If I comment out this record, the rest of my module imports without an issue, so I believe this is causing the problem. Is it not possible to alter a base field in this manner?
