I'm currently using Odoo 12.0+e-20181025 and I'm trying to add the followers of each ticket made in helpdesk into an automated email whenever it has been changed (not only in stage). So far I've tried some codes and managed to put the followers' emails into the body of the text, but in the recipient field.
Here is the code I used:
% for follower in object.message_follower_ids:${follower.email_formatted}%endfor
I can use it in the body text but I can't produce any result in the Email To field. Any help is greatly appreciated.
You could use ${str(object.message_partner_ids.ids).replace('[', '').replace(']', '')}
in "To (Partners)" field.
