Notice: Trying to get property of non-object in D:\phpStudy\WWW\SELF\yii\yiisns2\frontend\config\main.php on line 17

对应的是

  'aliases' => [
        '@views' => dirname(__DIR__) . "/views/",
        '@jsUrl' => Yii::$app->request->baseUrl."/js/"
    ],

请问怎么解决啊

@我的丶关键词

$query = Post::find()->select('max(id) as max_id ')->where('author_id = :author_id and status = :status', [':author_id'=>1, ':status'=> 2]);

看文档的查询构建器

还是预处理的更好用

Chat::find()->where('id > :id and uid = :uid', [':id'=>118, 'uid'=> 1])->asArray()->all();

如果先看到底运行的原生sql是什么可以用这样

$query = Post::find()->where('author_id = :author_id and status = :status', [':author_id'=>2, ':status'=> 2]);
      $commandQuery = clone $query;
      echo $commandQuery->createCommand()->getRawSql();

      print_r($query->all());

请问您在github上有可学习的源码吗
