yii：无法使用“through”获取图片

Question

我是一个yiibie，我陷入了一个问题。我在我的查看文件中创建了一个名为ngopage.php的文件，我可以从我的Ngo表中获取数据，但我无法获得针对ngo针对ngo的特定ID编写任何注释的用户的Picture。用户的图片位于profile表中，评论来自userRateReviewNgos表。我也能够获得评论，但没有得到用户的照片。我尝试userRateReviewNgos模型的relation function中的through方法，该模型给出了一个例外Property "CBelongsToRelation.through" is not defined.请帮我解决这个问题。谢谢。 这是我的UserRateReviewNgos model

Answer 1

的ngopage.php为此，我认为你应该使用一个具有一个关系

'profile' => array(self::HAS_ONE, 'Profile', 'user_id'),
