A scala validator that supports value classes mechanism. Currently no artifact yet.
case class Student(name: String, email: String, code: String, age:Int, grade: Int, enrolled: Boolean) extends RichValidator
val student = new Student("Klarenz","[email protected]","st1", 18, 99, true)
println(EmailText(student.email).isValid) // Prints true.
implicit val constraint = RichConstraint[Student](student)(s =>
s.name ? (nonEmpty(), alphabetic(), matches("^[A-z]+$")) ++
s.code ? (startsWith("s")) ++
s.email ? (nonEmpty(), email()) ++
s.age ? gt(1) ++
s.enrolled ? TRUE()
)
student.validate //Calling validate requires implicit RichConstraint and throws exception if invalid.
student.isValid //Calling validate requires implicit RichConstraint and Return true if valid.student.name ? equalsTo("Mark").errMsg("Error.. ") // Overrides the default exception messages.dingo is Open Source and available under the Apache 2 License.
