在phpactiverecord三重水平协会 [英] Triple level associations in phpactiverecord
问题描述
现在,如果我尝试渴望负荷超过深phpactiverecord两个对象,我得到一个错误。
Right now if I try to eager load more than two objects deep in phpactiverecord, I get an error.
什么是像这样的:
$conditions['include'] = array( 'playlists' => array('playlist_songs' =>array('song')));
User::find('first', $conditions);
太多只是一个层面,试图找回?
我发现了一个错误未定义抵消:0
每当我尝试使用深协会3个级别。
感谢任何帮助或洞察力。:D
Just one level too much to try to retrieve?
I'm getting an error Undefined offset: 0
whenever I try to use an association 3 levels deep.
Thanks for any help or insight :D.
编辑:
所以,我发现这是一个有些奇怪的图案。
如果我有阵列('playlist_songs'=>阵列('歌'=>阵列('专辑')));
,热切负荷将打破我。但是,如果我添加其他关联数组,然后它工作正常。阵列('playlist_songs'=>阵列(歌,歌,歌,歌=>阵列('专辑')));
So I've found a pattern that's a little odd.
If I have array('playlist_songs'=>array('song'=>array('album')));
, the eager load will break for me. But if I add another association to the array, it then works correctly.
array('playlist_songs'=>array('song','song','song','song'=>array('album')));
我用歌多次在该数组中只是为了让修复非常明显的。
I used 'song' multiple times in that array just to make the fix very apparent.
推荐答案
只需要通过
if (is_array($name))
{
$nested_includes = count($name) > 1 ? $name : $name[0];//<-- this line
$name = $index;
}
到
if (is_array($name))
{
$nested_includes = count($name) > 0 ? $name : $name[0];
$name = $index;
}
