Hi,

I'm working on Odoo 18.

Here's my issue: I need to display the activities from the child_ids of a contact in the Chatter component on the contact's view (res.partner).

To do this, I created a computed field all_activity_ids One2Many on res.partner, wich collects all the activities i want to display in the Chatter (including those from child_ids).

In short, i want to replace the default activity_ids field used by Chatter by my custom all_activity_ids, but only on the contact form view.

I thought about overriding activity_ids with the contents of my all_activity_ids, but that doesn't because activity filtrers should not include activities from the child contact.

I've tried different approaches using both JS and XML, but i haven't been able to achieve the expected result.

As a fallback, I also considered adding a second actvity list in the Chatter and disabling the default one for res.partner, but that didn't work either.

I don't know if I was cleared in the explication of my problem.

Does anyone have an idea of how I could achieve this properly ?

Thanks in advance !
