我使用 Data 连接系统在 Sails 中有一个 sails-cassandra 模型。数据。 Data.count({...}).exec() 返回 1，但 Data.find({...}).exec() 或 Data.findOne({...}).exec() 返回以下错误消息:
Error (E_UNKNOWN) :: Encountered an unexpected error

最佳答案
这可能是构造返回属性的一个问题，因为 count() 不返回任何属性，而 find() 和 findOne() 会。
我会看看你模型的属性。添加和删除每一个，直到找到罪犯。
关于node.js - Cassandra Sails model.count() 有效，但 model.find() 和 model.findOne() 无效，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/33084155/
