In an automated action, I would like to copy the name of the filed product_id field (using the notation .name) from the mrp.production model to a text custom field in the project.task model.
So using the product_id.name the system returns the name of the "product" (template) instead on the name of the "product variant" while in the same automated action the notation .id (product_id.id) returns, as expected, the ID of the "Product Variant" .
What's the correct syntax to use?
