def _get_users(self, cr, uid, ids, field_name, arg, context=None):
    res = {}
    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:
    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"),

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:
    return users_ids
