Yii2 Restful API：使用特定条件SQL将数据库中的数据显示为JSON格式

Question

I'm working on Yii2 restful API and want to display the data into JSON format. This is my structure database :

TABLE `volunteer`(
`volunteer_id` int(11) NOT NULL auto_increment,
`state_id` int(11) null
`nama` varchar(200) null

TABLE `state`(
`state_id` int(11) NOT NULL auto_increment,
`state` varchar(225) null

Basically, when I run at browser with specific ID = 1 ( http://localhost/KDMA/web/index.php/volunteers/1 ) the data will display like this:

{
   "volunteer_id": "1",
   "state_id":"12",
   "nama": "Bentong",
}

that result is display the data from volunteer_id = 1. So, what I want to do right now is display the data from state_id, not volunteer_id . For example in SQL:

SELECT * FROM volunteer where state_id = 12;

What are the ways that can solve my problem?

Answer 1

If I understand your question I think you can solve the problem as follows: try adding another method in the controller that performs the action you need eg in volunteerController

public function actionViewByState ($ id)
   {

     if (($ model = State :: findOne ($ id))! == null) {
         $ this-> setHeader (200);
     echo json_encode (array ('status' => 1, 'date' => array_filter ($ model-> attributes)), JSON_PRETTY_PRINT);
     } Else {

       $ this-> setHeader (400);
       echo json_encode (array ('status' => 0, 'error_code' => 400, 'message' => 'Bad request'), JSON_PRETTY_PRINT);
       exit;
     }
   }

and then call the action with

  http: //localhost/KDMA/web/index.php/volunteers/view-by-state/1
