Scala, Casbah: MongoCollection.插入编译错误

Question

我正在尝试编写使用Casbah工具包向MongoDB写入数据的函数:

  import com.mongodb.casbah.WriteConcern
      import ...
  def saveRecord(rec: MongoDBObject) {
    mongoColl.insert(rec)
  }

得到以下错误:

1) No implicit view available from Object => com.mongodb.casbah.Imports.DBObject.   
2) not enough arguments for method insert: (implicit dbObjView: Object => com.mongodb.casbah.Imports.DBObject, implicit concern: com.mongodb.WriteConcern, implicit encoder: com.mongodb.casbah.Imports.DBEncoder)com.mongodb.casbah.Imports.WriteResult. Unspecified value parameter dbObjView.    

怎么了?

Answer 1

我不确定是否完全导入，但尝试将MongoDBObject更改为com.mongodb.DBObject或添加import com.mongodb.casbah.Imports._
