Cakephp 3 findAuth join table return array - mysql

Question

I am attempting to implement a role based authentication system using a custom finder.
public function findAuth(\Cake\ORM\Query $query, array $options)
{
$query
->select(['id', 'username', 'passwordHash', 'locked', 'roles.role'])
->group('username')
->join([
'table' => 'user_roles',
'conditions' => ['user_roles.userid = Users.id']])
->join([
'table' => 'roles',
'conditions' => ['roles.id = user_roles.role']])
->toArray()
;
return $query;
}
The resulting mysql query i need is:
select users.id, username, passwordHash, locked, group_concat(roles.role) role from users INNER JOIN user_roles on user_roles.userid = users.id INNER JOIN roles on roles.id = user_roles.role group by users.id

What I finally ended up going with is this:
public function findAuth(\Cake\ORM\Query $query, array $options)
{
$query
->select(['id', 'username', 'passwordHash', 'locked'])
->join([
'table' => 'user_roles',
'conditions' => ['user_roles.user_id = Users.id']])
->contain(['UserRoles.Roles'])
->join([
'table' => 'roles',
'conditions' => ['roles.id = user_roles.role']])
->group(['Users.username']);
return $query;
}
This gives me a multi-dimensional array of:
user_roles[index[id, user_id, roles[id, role]]]
in my case I have 2 entries for the index (0 and 1) and I can check the role of the user with the in_array function within a foreach loop
