Was considering utilizing the magic findBy functions on a model today and encountered an issue when attempting to set optional parameters for the function. Here is what I tried.
正在考虑今天在模型上使用魔术findBy函数，并在尝试为函数设置可选参数时遇到问题。这是我尝试过的。
$result = $this->findById($id['Alpha.name']);
So to explain, I'm attempting to find a record with a specific id and only return the value of the name field. According to the documentation, there is a way to do this.
所以要解释一下，我试图找到一个具有特定id的记录，只返回name字段的值。根据文档，有一种方法可以做到这一点。
The findBy magic functions also accept some optional parameters:
findBy<fieldName>(string $value[, mixed $fields[, mixed $order]]);findBy魔术函数也接受一些可选参数：findBy
（string $ value [，mixed $ fields [，mixed $ order]]）;
CakePHP 1.3 Book :: findBy
When I do a simple findBy($id) I do get a result set. But with parameters, I get nothing. I know there are other ways to do this but was just curious if anyone has had any success using these magic functions with additional parameters?
当我做一个简单的findBy（$ id）时，我得到一个结果集。但有了参数，我什么都没得到。我知道还有其他方法可以做到这一点，但只是好奇，如果有人使用这些神奇功能与其他参数取得任何成功？

try this:
尝试这个：
$result = $this->findById($id, array('Alpha.name'));
where $id is an id of record you're searching for and Alpha.name is a field you need (e.g. name from model Alpha)
其中$ id是您要搜索的记录的ID，Alpha.name是您需要的字段（例如，来自模型Alpha的名称）
