Question

我将ember与parse数据库一起使用，并使用embe-parse-adapter

但我在获取记录后出现此错误

Error while processing route: index.index Cannot read property '_relationships' of null TypeError: Cannot read property '_relationships' of null

从我阅读的各种资源中，我怀疑它是因为在其中一个与其他模型有关系的字段中存在空值，

我怎么能处理这个？

javascript stacktrace是：

Error while processing route: index.index Cannot read property '_relationships' of null TypeError: Cannot read property '_relationships' of null

以及我使用的版本：
