[17.0] Incorrect display of tracked one2many field in chatter (tracking_manager module)

[melissalateb]

Module

tracking_manager

Describe the bug

• When I enable tracking on a one2many field in a custom model using the tracking_manager module, the tracked changes appear in the chatter. However, instead of showing the display name or a meaningful value, the system displays the raw IDs of the records (e.g., Modified: sale.order.linked, 24) in the chatter.

This issue does not occur when tracking one2many fields on standard models like sale.order.line. It seems specific to custom models. Am i missing something?

• The second thig is when changing a boolean field related (for example here sale.order.linked), it doesn't show both the before and after values; it only displays the new value with the arrow.

To Reproduce

1. Create a custom model with a One2many field ( in my example : sale.order.linked).
2. Enable tracking on this field.
3. Create records with the one2many field.
4. Modify a boolean related to one2many field save the record.
5. Observe the chatter for tracked changes.

Expected behavior

• The same think as Order Lines for tracking value.
• And more details about value changes before and after.

Additional context

Odoo 17.0 enterprise

False might be interpreted as <empty> and therefore an empty string is displayed. Where does the model sale.order.linked comes form? Could it be that this model does not have a display_name attribute? Therefore it displays model+id as fallback?

[CRogos]

I would like to add this finding when activating tracking on "child_ids" in res.partner:

• Two message are created. One odoo native and a second by tracking_manager.
• Content of New and Change in the tracking_manager message should be merged.

Maybe we can update the message content of the native message with the more detailed content of the tracking_manager message?

@CRogos ,

The model sale.order.linked is a custom model that I developed, and it doesn't have a display_name defined. Should I explicitly define one to make the tracking work properly?
