I need to call function in domain odoo 16 
I know that calling function in domain depricated in odoo16
but how can i solve this problem?

I tried to use compute field but it does't work


@api.onchange('deliver_id.shipping_method')
def _on_change_shipping_method(self):
    if self.deliver_id.Shipping_method:
        cities=self.env['shipping.meth']['line_ids']['city_id'].search_read()
        city_list={}
        for rec in cities:
            cit=self.deliver_id.Shipping_method.line_ids.city_id
            for c in cit:
                if rec['id'] == c.id:
                    city_list[c.id]=c.id
        return city_list
@api.depends("deliver_id.Shipping_method")
def _compute_allowed_value_ids(self):
    for record in self:
        x= _on_change_shipping_method()
        x=list(x.values())
        record.allowed_value_ids=x
allowed_value_ids = fields.Many2one(
    "city.city",
    _compute="_compute_allowed_value_ids",required=False
)
city = fields.Many2one('city.city',string='City',domain="[('id', 'in',  allowed_value_ids)]",)

Hello Asmaa,

I've checked the issue and here's what you can fix,

1) You need to remove '_' at beginning of compute parameter and write 'compute' instead as '_compute' is not a valid parameter.

2) The arguments used for onchange() decorator must be simple field names. If dotted names are used then it will be ignored by the decorator. Your onchange() decorator: ('deliver_id.shipping_method') will be ignored.

3) If your onchange method (in your case x) returns more than one value It throws an error, you cannot use them to write in Many2one as you can write only one value at a time in Many2one. 

So if your field 'allowed_value_ids' is not used in the view or anywhere else other than in the domain of field 'city', you can make the field type 
of field:'allowed_value_ids' as Many2many instead of Many2one.

Ex:- Suppose you have 3 cities, compute on your field 'allowed_value_ids' returns 2 cities, so it will write those two values in field 'allowed_value_ids' if it is a Many2many but not in Many2one. Now field 'city' will filter only those cities which are there in the field 'allowed_value_ids'. 

Hope this will help you.

Hi,

You can call the domain using a external module from oca, web_domain_field add this module in the depends in manifest file

https://odoo-community.org/shop/web-domain-field-4368#attr=22677

Try to update the code like this , import json

@api.depends("deliver_id.Shipping_method")
def compute_allowed_value_ids(self):
    for record in self:
        val = self._on_change_shipping_method()
        x = list(val.values())
        record.allowed_value_ids = json.dumps(
                [('id', 'in',x)]
            )

Update the xml code like follows

<field name="city" domain="allowed_value_ids"/>


<field name="allowed_value_ids" invisible="1"/>


Regards
