Hello,

I have a Many2many fields in sale order form, and I want that only that order line will show in many2many fields related to that sale order. So what domain I will use.

I have also made a field in order line name 'number' of char type in which when we create order line then the same sale order name is copied in 'number ' field. This field I have created  to make relationship between sale order and sale order line.

Code:

sale.py.

class SaleOrder(models.Model):

item_delivered_ids = fields.Many2many('sale.order.line',

'sale_order_sale_order_line_rel',

'sale_order_id',

'order_line_id',

string='Item Delivered')

class SaleOrderLine(models.Model):

    number = fields.Char(string='Order Number')

sale_view.xml:

<record id="view_sale_order_form_inherit" model="ir.ui.view">

<field name="name">sale.order.form.inherited</field>

<field name="model">sale.order</field>

<field name="inherit_id" ref="sale.view_order_form"/>

<field name="arch" type="xml">

    <xpath expr="//field[@name='partner_id']" position="after>

        <field name="item_delivered_ids" widget="many2many_tags" />

</xpath>

</field>

</record>

Thanks,
