控制器&＃xff1a;
获取帖子public function actionIndex()
{
$posts &＃61; Post::find();
$pagination &＃61; new Pagination([
&＃39;defaultPageSize&＃39; &＃61;> 2,
&＃39;totalCount&＃39; &＃61;> $posts->count()
]);
$posts &＃61; $posts->offset($pagination->offset)->limit($pagination->limit)->all();
return $this->render(
&＃39;index&＃39;,
[
&＃39;posts&＃39; &＃61;> $posts,
&＃39;pagination&＃39; &＃61;> $pagination
]
);
}
视图&＃xff1a;显示帖子文本和用户ID
foreach($posts as $post){ ?>
&＃61;$post[user_id]?>
&＃61;$post[text]?>
} ?>
我不能使用功能getUser因为$ post不是对象
和后期模型&＃xff1a;
命名空间app \ models;
使用yii \ db \ ActiveRecord;
类Post扩展ActiveRecord
{
/ **
* &＃64;inheritdoc
* /
公共静态函数tableName()
{
返回“发布”&＃xff1b;
}
/**
* &＃64;inheritdoc
*/
public function rules()
{
return [
[[&＃39;user_id&＃39;, &＃39;text&＃39;], &＃39;required&＃39;],
[[&＃39;user_id&＃39;], &＃39;integer&＃39;],
[[&＃39;text&＃39;], &＃39;string&＃39;]
];
}
/**

*/
public function attributeLabels()
{
return [
&＃39;id&＃39; &＃61;> &＃39;ID&＃39;,
&＃39;user_id&＃39; &＃61;> &＃39;User ID&＃39;,
&＃39;text&＃39; &＃61;> &＃39;Text&＃39;,
];
}
/**
* &＃64;return \yii\db\ActiveQuery
*/
public function getUser()
{
return $this->hasOne(User::className(), [&＃39;id&＃39; &＃61;> &＃39;user_id&＃39;]);
}
}
最佳答案
foreach($posts as $post){ ?>
&＃61; $post->user->username ?>
&＃61; $post->text ?>
} ?>
