Hi,

If your One2many field (chargable_lines) isn't showing any fields in the form view, it's likely because the view is missing a proper <tree> or <form> layout.

Please try with the following code.

<record id="view_wh_charges_form" model="ir.ui.view">
    <field name="name">wh.charges.form</field>
    <field name="model">wh.charges</field>
    <field name="arch" type="xml">
        <form string="Warehouse Charges">
            <sheet>
                <group>
                    <group>
                        <field name="name"/>
                        <field name="partner_id"/>
                        <field name="date"/>
                        <field name="related_invoice_id"/>
                        <field name="currency_id"/>
                    </group>
                    <group>
                        <field name="total_bill"/>
                    </group>
                </group>
                <notebook>
                    <page string="Charges">
                    <field name="chargable_lines">
                        <tree editable="bottom">
                            <field name="product_id"/>
                            <field name="price"/>
                            <field name="billed_qty"/>
                            <field name="total"/>
                            <field name="currency_id"/>
                        </tree>
                    </field>
                    </page>
                </notebook>
            </sheet>
        </form>
    </field>
</record>

Hope it helps.

Hi,
Have a  look at this: Working Of One2Many Fields in Odoo

Thanks

Hello Pete Charalampopoulos,

I hope you're doing well.

I noticed that there is no relation field between the two models in the tree view. If you haven't already created a relationship between these tables, you'll need to do so. I've shared the code below for your reference:

Python:

class WhCharges(models.Model):

    _name = 'wh.charges'

    # Add a One2many field to create a relation with 'wh.charges.line'

    wh_changes_id = fields.One2many('wh.charges.line', 'wh_changes_id')

class WhChargesLine(models.Model):

    _name = 'wh.charges.line'

    # Add a Many2one field to create a relation with 'wh.charges'

    wh_changes_id = fields.Many2one('wh.charges')

This should establish the internal link between the two models.

Hope this helps!

Thanks & Regards,
