// End setup

// Lets begin with a fresh instance, retrieved from the DB
$retrieved = R::findOne('child', 'name = ?', ['Jack']);

// We can create a fresh instance, and inject into it without errors
$imported = R::dispense('child');
$imported->inject($retrieved);

// The record has no 'parent' property, as expected, because we haven't lazy-loaded it yet
var_dump($retrieved->getProperties()['parent_id']);      // 1
var_dump($retrieved->getProperties()['parent'] ?? null); // null

// Now we lazy load it
$retrieved->parent;

// And now we see it on the record
var_dump($retrieved->getProperties()['parent_id']); // 1
var_dump($retrieved->getProperties()['parent']);    // OODBBean parent object

// But now injecting into a fresh instance no longer works
$imported = R::dispense('child');
$imported->inject($retrieved);
