cakephp - Creating new record if the id is not in db -

-

i working on cakephp 2.x , want create new row or record if userid not present in db otherwise update record, problem is: not updating current record. creating record userid "0" dont know problem is. if not finding record should create record userid giving.

public function activenostatus(){       $this->loadmodel('status');     $userid =  $this->request->data('iduser');     $notify =  $this->request->data('notify');      $data = array();     $data['activeno'] = $notify;         $count =  $this->status->finduserid($userid);     if($count>0){         $this->status->id = $userid;         $this->status->save($data);           echo "update";     }else{              //create new row           $datanew=array();          $this->status->id = $userid;          $this->request->data['status']['activeno']=$notify;            $this->status->save($this->request->data);           echo "ok";     }    }

it seems iduser field not autoincrement, in cakephp documentaion :

all tables cakephp models interact (with exception of join tables), require singular primary key uniquely identify each row. if wish model table not have single-field primary key, cakephp’s convention single-field primary key added table. have add single-field primary key if want use table’s model.

rather using auto-increment key primary key, may use char(36). cake use unique 36 character uuid (string::uuid) whenever save new record using model::save method.

so should make iduser autoincrement primary key.
