Transfer-ORM:在对象'siteID‘中找不到属性'siteUsers.siteUsers’

Question

当使用Transfer映射到我的Microsoft数据库时，我将得到以下Cold聚变错误。我认为这是由一个配置错误的transfer.xml文件造成的，该文件映射了我的链接表。我不确定我完全理解合成id的细微差别。你看到错误了吗？

错误：

找不到搜索的属性，在对象'siteID‘中找不到属性'siteUsers.siteUsers’

index.cfm：

<cfset transfer = application.transferFactory.getTransfer()>
<cfset obj = transfer.new("users.users")>
<cfdump var="#obj#">

transfer.xml：(相关部分-我认为siteUsers包中存在问题)

Answer 1

可能的原因是您为相同的关系同时定义了o2m和m2o。我记得，这是不允许的。

Answer 2

要正确配置Transfer-ORM，需要对配置文件进行三项验证：

1. 它是否有正确的XML格式？
2. 它是否符合transfer.xsd模式文件？
3. transfer.xml中的关系与数据库中的关系匹配吗？

我通过了对#1和#2的验证，但是在#3中使用了错误的关系标记。
