Hi,

Try this,

class AccountPayment(models.Model):
    _inherit = 'account.payment'

    move_ids = fields.One2many('account.move.line', 'payment_id', string='Bill lines')

class AccountMove(models.Model):
    _inherit = 'account.move'

    payment_id = fields.Many2one('account.payment', string='Payment')
XML
<record id="view_account_payment_form" model="ir.ui.view">
    <field name="name">account.payment.form</field>
    <field name="model">account.payment</field>
    <field name="inherit_id" ref="account.view_account_payment_form"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='ref']" position="after">
            <page name="payment_lines" string="Payment Lines">
                 <field name="move_ids" widget="one2many_list">                 
                     <tree string="Requisitions Lines" editable="bottom">
                     // add required fields here
                     </tree>
                 </field>
            <page>
        </xpath>
    </field>
</record>




Thanks

                

Hi,

To display the tree view of products from the bill (account.move) directly in the Payment view (account.payment) in Odoo 15 Community version, you can achieve this by adding a custom related field to the Payment model that fetches the related products from the bill.

* Inherit the model "account.payment" and add related_product_ids Many2many field.
In Python:
class AccountPayment(models.Model):
    _inherit = 'account.payment'

    related_product_ids = fields.Many2many(
        'product.product',
        string='Related Products',
        compute='_compute_related_products',
        help='Products from the related bills'
    )

    @api.depends('invoice_ids')
    def _compute_related_products(self):
        for payment in self:
            related_products = payment.invoice_ids.mapped('invoice_line_ids.product_id')
            payment.related_product_ids = [(6, 0, related_products.ids)]

In XML:

<odoo>
    <data>
        <record id="view_account_payment_form_inherit" model="ir.ui.view">
            <field name="name">account.payment.form.inherit</field>
            <field name="model">account.payment</field>
            <field name="inherit_id" ref="account.view_account_payment_form"/>
            <field name="arch" type="xml">
                <field name="amount" position="after">
                    <field name="related_product_ids" widget="many2many_tags"/>
                </field>
            </field>
        </record>
    </data>
</odoo>

Hope it helps
