Hi all,

I'm struggling to pass a context to a tree view field, which is nested inside a form view. Not 100% certain but I'm pretty sure I've done this successfully before. Is it due to Odoo V14 ?

When I create a new credit, i would like the building field to be populated before saving the record.

My form view :

<record model="ir.ui.view" id="bld_building_form_view">
    <field name="name">bld.building.form</field>
    <field name="model">bld.building</field>
    <field name="arch" type="xml">
    <form string="Building">
...
        <field name="id"/>
        <field name="credits" string="Credits" context="{'default_building_id': id}">
            <tree string="Credits">
                <field name="name"/>
                <field name="amount" widget="monetary" sum="Total"/>
                <field name="interest_rate" string="Annual interest rate %"/>
                <field name="start_date"/>
                <field name="building_id"/>
            </tree> 
        </field>
...

My model :

class Building(models.Model):
    _name = 'bld.building'
    _inherit = ['mail.thread', 'mail.activity.mixin']
    _description = 'Building'

    credits = fields.One2many('bld.credit', 'building_id', string='Credits', copy=True, auto_join=True)

class Credit(models.Model):
    _name = 'bld.credit'
    _description = 'Credit'
    
    building_id = fields.Many2one('bld.building', string='Building', required=True, index=True, copy=True)
    name = fields.Char(required=True)
    amount = fields.Monetary(store=True)
    interest_rate = fields.Float(string='Annual interest rate', store=True)
    start_date = fields.Date()
