[14.0] Image Widget not loading when record.name is many2x type (e.g. product.supplierinfo)

[joshkreud]

Impacted versions:
14.0

Steps to reproduce:

1. Add a related image field to product.supplierinfo (we_product_tmpl_image = fields.Image(related='product_tmpl_id.image_256'))
2. Show that image in the supplier form view: (<field name="we_product_tmpl_image" widget="image" />)
3. Try to open form view

Current behavior:

Image wont load, because product.supplierinfo.name is a many2one:

The above exception was the direct cause of the following exception:

TypeError: expected str, bytes or os.PathLike object, not res.partner - - -

Expected behavior:

Image should load without error.

Maybe there should be a check, wether the filename is a record, and if yes, fall back to display_name?
Or make filename_field configurable via an XML attribute on the widget.

Any solution for this issue? Same issue on version 15
