Question

we have a list of items in one model named us_inventory_line. We have another model named ladings...

class inventory_line(models.Model):
    # ...
    lading_item = fields.Many2one('res.lading', ondelete='set null', string="lading", index=True)

class Lading(models.Model):
    # ... 
    us_inventory_line_item = fields.One2many(comodel_name='rodals.us_inventory_line', string="shippments", inverse_name='lading_item')

In the form, we have just simply put the field that represent one2many:

<!-- Form -->
<record model="ir.ui.view" id="us_inventory_line_form_view">
    <field name="name">lading.form</field>
    <field name="model">rodals.lading</field>
    <field name="arch" type="xml">
        <form string="Invetory Line Form">
            <sheet>
                <group>
                    <field name="delivery_date"/>
                    <field name="us_inventory_line_item"/>
                </group>
            </sheet>
        </form>
    </field>
</record>

When the application is opened, when the user opens the lading page, he is only able to add new us_inventory_line.

How do we go about in order to connect the tow ? Like the user need to choose, from a list of us_inventory_line that does not have a lading (because if its has lading, this means that its already shipped).

Thank you very much for the help !
