Lightbend示例语法错误

Question

I just wonder if I have messed something up or is it just unavoidable pain of using Scala. I wanted to test out slick so I decided to run activator-play-slick-angularjs example from Lightbend . Unfortunatelly I get syntax errors while using

lazy protected val empTableQuery: TableQuery[EmployeeTable] = TableQuery[EmployeeTable]

in any possible way. In filtering examples, the type I am required by Scala plugin to use is Any eg

def delete(id: Int): Future[Int] = db.run { empTableQuery.filter(_.id === id).delete }

_.id part yields syntax error. I bet that I am just missing something because I can't imagine a single developer willing to work in 2017 without syntax assistance from IDE.

Answer 1

In case somebody met this problem in future - in this example EmployeeTable is defined with private[EmployeeTable] what makes in not visible in EmployeeRepository class. Just skip the private[EmployeeTable] part in class definition to make everything work smoothly.
