class a(models.Mocel):
    _name='a'
    master = field.Char()
    slave = field.One2many('b','a_id')

class b(models.Model):
    _name='b'
    a_id=field.Many2one('a')
    c_id=field.Many2one('c')

class c(models.Model):
    _name='c'
    code=field.Char()

and the view for model "a"

<field name="master"/>
<field name="slave">
    <tree editable="bottom">
        <field name="c_id"/>
    </tree>
</field>

I need to filter "c" so that a.master=c.code so I tryed:

@api.onchange('master')
def onchange_master(self):
    return {'domain': {'slave.c_id': [('code','=',self.master)]}}

and

@api.onchange('master')
def onchange_master(self):
    return {'domain': {'slave': [('code','=',self.master)]}}

and

@api.onchange('master')
def onchange_master(self):
    return {'domain': {'c_id': [('code','=',self.master)]}}

but it just doesn't set the domain for c_id field. Is there any way to achieve this, or it is just not possible?

Dear  Praful chavdam
​

We can achive your requirment,
just try the bellow codes.

 .py

# -*- encoding: utf-8 -*-
from odoo import api, fields, models, _

​
class A(models.Model):     
_name = 'a'

    name = fields.Char()
    slave = fields.One2many('b', 'a_id')


class B(models.Model):     
_name = 'b'
_rec_name = 'a_id' 
a_id = fields.Many2one('a')
a_rel = fields.Char(related='a_id.name', readonly=1)
c_id = fields.Many2one('c') 

 @api.onchange('a_rel')  def onchange_master(self):
     return {'domain': {'c_id': [('name', '=', self.a_rel)]}}
class C(models.Model):
    _name = 'c' 
    name = fields.Char()​
.XML
        
 <group>

        field name="name"/>
field name="slave">
<tree editable="bottom">
<field name="c_id"/>
<field name="a_rel"/>
<field name="a_id"/>
</tree>
</field>
</group>
