Cakephp3 Sumof Containable Data - cakephp

Question

I have an Articles model and Ratings model. An Article hasMany Ratings. I want to find the 10 highest rated Articles in the past 60 days.. The problem as I see it is that i have to get the sumOf 'score' on a containable model.
This is what I have tried:
$articles = $this->Articles->find()
->where( 'Articles.publish >' => (new Time())->subDays(60))
->contain([
'Ratings' => function ($q) {
return $q->select(['id', 'article_id', 'total' => func()->sum('score')
]);
},
])
->order(['Ratings.total' => 'DESC']);
The other approach would be to query Ratings first to tge the 10 highest total scores then leftJoin on Articles. This doesn't seem very efficient though as I have 2500+ articles and I don't want to add overhead by totalling score for Articles that won't be included as they are to old to be included.

Answer 1

Please check below code using left join
$query = $this->Articles->find();
$query->limit( 10 );
$query->where( ['Articles.created >' => (new Time())->subDays(60)]);
$query->select( [
'Articles.id',
'Articles.title',
'sumrating' => $query->func()->sum( 'Ratings.rating' ),
'Articles.created',
'Articles.modified'
] );
$query->leftJoin(
[ 'Ratings' => 'ratings' ],
[ 'Ratings.article_id = Articles.id' ]
);
$query->group( [ 'Articles.id' ] );
$query->order( [ 'sumrating'=> 'DESC' ] );
$articles = $query ;
$this->set(compact('articles'));
