CakePHP 3 - How do I use left joins in a query - mysql

Question

I have the following query that works, but after talking to the client I realized I need left joins to get the desired results and I don't know how to do it.
This is my query:
$query = $this->AssetStatusAudits->find('all', [
'contain' => [
'AssetStatus',
'Users',
'Assets' => function ($q) {
return $q->contain([
'Employees',
'Sites'
]);
}
],
'conditions' => [
'AssetStatusAudits.created >' => $from,
'AssetStatusAudits.created <' => $to
]
]);
$query->select([
'createdDate' => 'date(AssetStatusAudits.created)',
'assetStatus' => 'AssetStatus.desc_en',
'firstName' => 'Users.first_name',
'lastName' => 'Users.last_name',
'count' => $query->func()
->count('*')
])
->group('date(AssetStatusAudits.created)', 'assetStatus.desc_en', 'users.last_name')
->order('Users.last_name', 'Users.created');
The above query generates this in cake:
SELECT date(AssetStatusAudits.created) AS `createdDate`,
AssetStatus.desc_en AS `assetStatus`,
Users.first_name AS `firstName`,
Users.last_name AS `lastName`,
(COUNT(*)) AS `count`
FROM asset_status_audits AssetStatusAudits
INNER JOIN asset_status AssetStatus ON AssetStatus.id = (AssetStatusAudits.asset_status_id)
INNER JOIN users Users ON Users.id = (AssetStatusAudits.user_id)
INNER JOIN assets Assets ON Assets.id = (AssetStatusAudits.asset_id)
LEFT JOIN employees Employees ON Employees.id = (Assets.employee_id)
INNER JOIN sites Sites ON Sites.id = (Assets.site_id)
WHERE (AssetStatusAudits.created > date('2016-01-13') AND AssetStatusAudits.created < date('2016-05-03'))
GROUP BY date(AssetStatusAudits.created)
ORDER BY Users.last_name
But this is the query that I need to add to cakePHP and I don't know how to do it:
SELECT
date(asset_tracking.asset_status_audits.created) as 'Date',
asset_tracking.asset_status.desc_en as 'Status',
asset_tracking.users.first_name as 'First Name' ,
asset_tracking.users.last_name as 'Last Name',
count(*)
FROM asset_tracking.asset_status_audits
LEFT OUTER JOIN asset_tracking.assets ON asset_tracking.asset_status_audits.asset_id = asset_tracking.assets.id
LEFT OUTER JOIN asset_tracking.asset_status ON asset_tracking.asset_status_audits.asset_status_id = asset_tracking.asset_status.id
LEFT OUTER JOIN asset_tracking.users ON asset_tracking.asset_status_audits.user_id = asset_tracking.users.id
LEFT OUTER JOIN asset_tracking.employees ON asset_tracking.assets.employee_id = asset_tracking.employees.id
LEFT OUTER JOIN asset_tracking.sites ON asset_tracking.assets.site_id = asset_tracking.sites.id
WHERE asset_tracking.asset_status_audits.created between date('2016-01-13') and date('2016-05-19')
group by
date(asset_tracking.asset_status_audits.created) ,
asset_tracking.asset_status.desc_en,
asset_tracking.users.last_name
ORDER BY asset_tracking.users.last_name, asset_tracking.users.created;
