Mapping a MongoDB collection to a Scala class


In the previous recipe, we learned how to connect a Lift application to a MongoDB database. Now, we will learn how to map a collection from MongoDB to a Scala class so we can use it to store and retrieve data into and from the MongoDB collection.

Getting ready

Let's modify the project from the previous recipe because it already has the connection configured.

How to do it...

Carry out the following steps:

  1. Create a file named Contact.scala in the model package using the following code:

    package code.model
    
    import net.liftweb.mongodb.record._
    import net.liftweb.mongodb.record.field._
    import net.liftweb.record.field.StringField
    
    class Contact extends MongoRecord[Contact] with ObjectIdPk[Contact] {
      def meta = Contact
    
      object name extends StringField(this, 150)
    }
    
    object Contact extends Contact with MongoMetaRecord[Contact]
  2. Create a file named Contacts.scala in the snippet package with the following code:

    package code.snippet
    
    import code.model._
    import...
