How to pull the ID of a relationship using the find function

Hi,

I am using the tutorial from the find function the doc but can’t find a way to pull the ID of a Simple Relationship (custom defined list). I defined ID|VALUE such as the following:

1|Easy
2|Moderate
3|Hard
4|Very Hard

I can’t find if there is specific magic tag to pull the ID from a relationship. I tried .ID without success. Can you please guide me into the right direction?

// Here's how to use find()
$params = array(
    'limit' => 3, 
    'page' => 2, 
    // Be sure to sanitize ANY strings going here
    'where'=>"category.name = 'My Category'"
);

// Run the find
$mypod = pods( 'mypod', $params );

// Loop through the records returned
while ( $mypod->fetch() ) {
    echo $mypod->display( 'myrelationship' ) . "\n";
}

This is returning the value “Easy” by example, and what I want is the ID (ex: 1).

Thank you
