Hello Friends,

I want to apply attrs on other fields select from many2many field.

in .py file which have

classs student_info(osv.Model):

_name = 'student.info'

_columns = {

'nick_name_ids': fields.many2many('nick.name', 'student_nick_name_rel', 'student_id', 'nick_id', string='Nick Name'),

'nick_name_1': fields.char('Nick Name 1'),

'nick_name_2':fields.char('Nick Name 2'),

'nick_name_2':fields.char('Nick Name 3').

}

now in .xml file

<record id="view_student_info_form" model="ir.ui.view">
            <field name="name">view.student.info.form</field>
            <field name="model">student.info</field>
            <field name="arch" type="xml">
                <form string="Student Info Form View">
                    <sheet>
                        <group>
