Mapping a table to a Scala class


Now that we know how to connect Lift applications to the database, the next step is to learn how to create mappings between a database table and a Scala object using Mapper.

Getting ready

We will re-use the project we created in the previous recipe since it already has the connection configured.

How to do it...

Carry out the following steps to map a table into a Scala object using Mapper:

  1. Create a new file named Contact.scala inside the model package under src/main/scala/code/ with the following code:

    package code.model
    
    import net.liftweb.mapper.{MappedString, LongKeyedMetaMapper, LongKeyedMapper, IdPK}
    
    class Contact extends LongKeyedMapper[Contact] with IdPK {
      def getSingleton = Contact
    
      object name extends MappedString(this, 100)
    }
    
    object Contact extends Contact with LongKeyedMetaMapper[Contact] {
      override def dbTableName = "contacts"
    }
  2. Add the following import statement in the Boot.scala file:

    import code.model.Contact
  3. Add the following code into the boot...
