CakePHP How to Get Associated Data and COUNT/GROUP BY - cakephp

Question

I'm having some trouble with Cakephp Query builder and try to get results I'm looking for. I have three tables 'Users', 'Items', 'Owns', where Owns belongs to both 'Users' and 'Items'.... A user can own many items (and many of the same items).
So I'm wanting to return the "owned" items by a user along with the count... However whenever I add count into my query I lose the associated Items data.
example - this returns the user data along with associated owns data and associated items data as shown below the query
$owns = $this->Users->get($id, [
'contain' => [
'Owns' => function($q) { return $q->find('all')->group(['Owns.item_id']); },
'Owns.Items'
],
]);
SQL Generated from this is
SELECT
Owns.id AS Owns__id,
Owns.item_id AS Owns__item_id,
Owns.user_id AS Owns__user_id,
Items.id AS Items__id,
Items.name AS Items__name,
Items.description AS Items__description,
Items.created AS Items__created,
Items.modified AS Items__modified
FROM
owns Owns
INNER JOIN items Items ON Items.id = (Owns.item_id)
WHERE
Owns.user_id in (1)
GROUP BY
Owns.item_id
Data results look like this:
'owns' => [
'id' => (int) 1,
'username' => 'myusername',
'owns' => [
(int) 0 => object(App\Model\Entity\Own) id:0 {
'id' => (int) 2
'item_id' => (int) 1
'user_id' => (int) 1
'item' => object(App\Model\Entity\Item) id:1 {
'id' => (int) 1
'name' => 'Item Name'
'description' => 'Item Description'
However in the 'owns' query I want to add in the count (i.e. the number owned). I can get the count by using this query but then I lose the associated item object from my results. I've tried this many different ways but always seems that if I want to use SQL count I can't get the associated data.
$owns2 = $this->Users->get($id, [
'contain' => [
'Owns' => function($q) { return $q->select(['count' => $q->func()->count('Owns.id'),'Owns.id', 'Owns.user_id', 'Owns.item_id'])->group(['Owns.item_id']); },
'Owns.Items'
],
]);
SQL Generated from this is
SELECT
(COUNT(Owns.id)) AS count,
Owns.id AS Owns__id,
Owns.user_id AS Owns__user_id,
Owns.item_id AS Owns__item_id
FROM
owns Owns
INNER JOIN items Items ON Items.id = (Owns.item_id)
WHERE
Owns.user_id in (1)
GROUP BY
Owns.item_id
Data results look like this:
'owns2' => [
'id' => (int) 1,
'username' => 'myusername',
'owns' => [
(int) 0 => object(App\Model\Entity\Own) id:36 {
'count' => (int) 4
'id' => (int) 2
'user_id' => (int) 1
'item_id' => (int) 1
Any insight into how I can get "count" into the first $user query or the associated items into the $user2 would be appreciated.

To keep the association table's fields that are returned in the $owns = find('all') query along with the SQL count function I needed to add the associated fields into the select statement
$owns2 = $this->Users->get($id, [
'contain' => [
'Owns' => function($q) { return $q->select(['count' => $q->func()->count('Owns.id'),'Owns.id', 'Owns.item_id','Owns.user_id', 'Items.id', 'Items.collection_id','Items.name', 'Items.description'])->group(['Owns.item_id']); },
'Owns.Items'
],
]);
