Question

我使用模型关联加入了两个表。这两个表格为<div class="header"> <div id="logo"> <img src="http://placehold.it/200x100"> </div> <div class="navbar"> <div id="leftnavbar"> <ul> <li><span id="dollarydoos">Dollarydoos:</span> <span id="dosh">1.00000000</span> <span id="dsh">DSH</span></li> </ul> </div> <div id="rightnavbar"> <ul> <li><a href="index.html">Button1</a></li> <li><a href="index.html">Button2</a></li> <li><a href="index.html">Button3</a></li> <li><a href="index.html">Button4</a></li> </ul> </div> </div> </div>和films但是有一些错误

我的查询：

movie_streams

Film.php模型：

$film = Film::model()->with('movie_streams')->find(array('select' => '*', 'condition' => 'user_id=:user_id, 'params' => array(':user_id' => $user_id)));

错误讯息：

public function relations() {
    return array(
              'movie_streams' => array(self::HAS_MANY, 'MovieStream','movie_id'),              
    );
}

我默认看到了别名。对于CDbCommand failed to execute the SQL statement: SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'user_id' in where clause is ambiguous表films和t表movie_streams

如何为上面两个表设置手动别名我想要的内容？

Answer 1

您可以通过指定关系的别名属性来避免表别名的冲突。

$comments = Comment::model()->with(array(
     'author',
     'post',
     'post.author' => array('alias' => 'p_author'))
   )->findAll();

Answer 2

使用

model_name.feild_name

$film = Film::model()->with('movie_streams')->find(array('select' => '*', 'condition' => 'film.user_id=:user_id, 'params' => array(':user_id' => $user_id)));

或

使用allias

避免表冲突

$comments=Comment::model()->with(array(
 'author',
  'post',
  'post.author'=>array('alias'=>'p_author')))->findAll(array(
   'order'=>'author.name, p_author.name, post.title'
 ));
