I need to create many2one field.but it should need to filter data as per my logic in function.then how to implement this in OpenERP ver 7 ?

i tried with below code.but its not give a list.just load as a readonly field : 

def _get_users(self, cr, uid, ids, field_name, arg, context=None):
    res = {}
    users_list=[]
    officer_ids = self.search(cr, uid , 'bpl.officer', [('is_user', '=', True)])
    officer_obj = self.browse(cr, uid, officer_ids, context=context)
    for record in officer_obj:
        users_list.append(record.user_id.id) 
    user_obj = self.pool.get('res.users')
    for data in self.browse(cr, uid, ids, context=context):
        res[data.id] = users_list
    return res

_name = "bpl.officer"
_description = "Officer registration details"
_columns = {
    'bpl_company_id':fields.many2one('res.company', 'Company', help='Company'),
    'bpl_estate_id':fields.many2one('bpl.estate.n.registration', 'Estate', help='Estate', domain="[('company_id', '=', bpl_company_id)]"),
    'bpl_division_id':fields.many2one('bpl.division.n.registration', 'Division', help='Division', domain="[('estate_id','=',bpl_estate_id)]"),
    'name': fields.char('Name', size=128, required=True),
    'is_user': fields.boolean('Is User', help="Is System user or not"),
    'user_id': fields.function(_get_users, type="many2one",relation="res.users"),

Hi Of course yes , Fuction field is a readonly field, it just update when record being update

and return only value shown in that field according to method of that field you should use domain in method

no list of value you can select in function many2one field

Thanks

If you want to filter data as per your logic then you should call your method from _defaults and make your field fields.many2one instead of fields.function.

Like this:

'user_id': fields.many2one("res.users", "Users"),

_defaults = {
    'user_id': _get_users,
}

And then change the code in your method.

Try this:

def _get_users(self, cr, uid, context=None):
    users_ids = []
    officer_ids = self.search(cr, uid , 'bpl.officer', [('is_user', '=', True)])
    for record in self.browse(cr, uid, officer_ids, context=context):
        if record.user_id:
            users_ids.append(record.user_id.id)
    return users_ids
