Yii2 rest API与用户一起发布

Question

I am creating REST API in YII2. I am getting all post data by calling get API

/post/
/post/1/

But I want to get user also who post that particular post.

for example I want data in below format

{
      "id":"1",
      "title":"kapil",
      "content" : "test",
      "user" : {
         "username":"admin",
         "first_name":"kapil",
         "last_name":"sharma",
          //blah blah
      }

}

But response is

{
          "id":"1",
          "title":"kapil",
          "content" : "test",
}

I used this tutorial for creating API.

Answer 1

Let's say in your post method you have the getIdUser() relation:

public function getIdUser() {
  return $this->hasOne(User::className(), ['id' => 'user_id']);
}

In that model, you should make use of the extraFields() method, as follows:

public function extraFields() {
  return [
    'user' => 'idUser' // or the name you hasOne relation with user has
  ];
}

Then, you call your REST API with the expand parameter, specifying there which extraField details you'd like to include, in your case:

http://example.com/post/view?id=1&expand=user
