  • A model [m] with a many2many field [m2m]
  • Field [m2m] have attribute [copy=False]
  • A form view [v] display the [m] and the field [m2m] with widget [many2many_tags]

I have tested that the python object did return a with False on field [m2m]

but the javascript, keep render the tags on web.

model.py 

class model(models.Model):
    _name = "m"

    m2m = fields.Many2many('sale.order', string="SO", copy=False)

XML File

<record ...>

<form>
<group>
    <field name="name"/>
    <field name="ref"/>
    <field name="so_m2m" widget="many2many_tags" options="{'no_create_edit': True}"/>
    </group>
</form>
</record>

When I duplicate the current record, the field [m2m] is keeps the old tag from old record which is not expected.

After clicking the save button, the old tag will disappear.

So here you want something like when you duplicate record then m2m field value should not copy, right ? – Keval Mehta
yes, i do not want to copy the value, i have set copy=False, and it did work at the record level, but the UI level tags are copied. – Ken Ho
Which kind of tags ? Can you explain what include in term 'tag' as per you ? – Keval Mehta
I used the widget many2many_tags to for the field. – Ken Ho

Try one thing here :

Whatever your third table is there, both fields used in many2many relation, from third table keep them as a copy false.

i.e. 

    m2m = fields.Many2many('sale.order','sale_order_another_table_rel', 'sale_order_field','antother_table_field', string="SO", copy=False)

Into new table : 

_name = 'sale.order.another.table.rel'
sale_order_field_id = // copy=false
another_table_field_id = //copy = false

Hopefully work.
