Odoo unknown currency_field 'currency_id'

Question

In Odoo 9 community version, I added the following monetary field as a monetary amount via the web interface: res.partner.x_tablet_bail_amount.

It's working fine, but when installing any new module I get the following error and my module does not install. Any help? thanks!

AssertionError: Field res.partner.x_tablet_bail_amount with unknown currency_field 'currency_id'

Answer 1

Fields of type monetary are using other fields to do some stuff like printing currency symbols in reports or the client. Per default currency_id is used (Odoo Code) for that process, and as far as i know there is no currency_id defined on res.partner.

So maybe you should define it or get it as related field from another relation?
