Creating one-to-many relationships

After learning how to map a database table to a Scala class using Record, we will learn how to take the next step, which is mapping a one-to-many relationship using Record.

Getting ready

We are going to modify the project from the last recipe. You can duplicate the project or modify it; it is your choice.

Create a table called phones:

create table phones (
  id serial primary key,
  number varchar(15),
  contact bigint
)

Add the following import statements in the Boot.scala file:

import net.liftweb.http.S
import net.liftweb.util.LoanWrapper
import net.liftweb.squerylrecord.RecordTypeMode._

Add the following code into the boot method in the Boot.scala file:

S.addAround(new LoanWrapper {
  override def apply[T](f: => T): T = inTransaction(f)

Now, you won't need to invoke the inTransaction or transaction methods.

How to do it...

In the model folder, create a new file named Phone.scala containing the following code:
```
package code.model 

import net.liftweb.squerylrecord...
```
