Unable to Display "Evaluations" Tab in a Form

[mahija (Ma)]

I am developing a Patient Evaluation feature in a Tryton-based system.
Evaluations should appear under the “Evaluations” tab in the xxx.patient form, but they are not visible.

Models Used:

1. xxx.patient.evaluation

• Fields: code, evaluation_start, evaluation_endtime, state
• Many2One relationship to xxx.patient

2. xxx.patient

• Field evaluations as One2Many to xxx.patient.evaluation

Form XML Code:

I have added the following code in xxx_patient_form.xml:

<page string="Evaluations">
    <field name="evaluations">
        <tree editable="bottom">
            <field name="code"/>
            <field name="evaluation_start"/>
            <field name="evaluation_endtime"/>
            <field name="state"/>
        </tree>
    </field>
</page>

However, the data does not appear under the Evaluations tab.

What I Have Tried:

1. Checked Access Rights (ir.model.access)

• xxx.patient.evaluation has no explicit access rule
• I added access for the Health Doctor group, but it still does not appear

2. Checked if Data Exists in the Database:

SELECT * FROM xxx_patient_evaluation WHERE patient = (SELECT id FROM xxx_patient WHERE name = 'Suwidarmo');

• This query failed because the name field in xxx.patient is a Many2One to party.party, not a direct string.
• After correcting it, I confirmed that the data exists in the database, but still does not show up in Tryton.

3. Checked the Model Definition in Python (xxx.patient)

evaluations = fields.One2Many(
    "xxx.patient.evaluation", "patient", "Evaluations",
    help="List of medical evaluations associated with this patient."
)

• This looks correct, but the data still does not appear in the UI.

Error occured

    field = cls._fields[fname]
KeyError: 'code'

Questions:

1. Could there be access rights or domain constraints preventing evaluations from being displayed?
2. Are there any ir.model.access or ir.ui.view configurations that I might have missed?
3. How can I ensure the evaluations field is properly displayed in the patient form?

Any help would be greatly appreciated!

I think that the problem is the view definition. Have you tried simplifying your XML code to just this and try if it works?

@mahija

<page string="Evaluations">
    <field name="evaluations"/>
</page>

If you want to display a specific view of the evaluation model, you should use view_ids attribute. There are a lot of examples in the code you can check.
