Cakephp - get database data from not associated models

Question

I wanted to ask, how can i get data from one table and use this in other find.

For example, i have films table. I want to get highest rated 3 films. Result should return 3 ID's.

Now, i want to create other query from not associated table, and pass this 3 ID's as "conditions" to find data in other table.

I dont want to use associations, because, data is stored in many databases, and this is problematic.

Thank You.

Answer 1

Once you've got your film IDs you can use in to filter the results from your other Model :-

$filmIds = ['32','55','75'];

$query = TableRegistry::get('Model')->find()
    ->where(function ($exp, $q) use ($filmIds) {
        return $exp->in('film_id', $filmIds);
    });
// WHERE film_id IN ('32','55','75')

Check out the docs section on advanced conditions .

If you need to get your film IDs into the correct format ( ie that shown in the example code) you can use Hash::extract() on the results from your previous query.

Answer 2

if your cakephp version 3.x you can use subqueries in fairly intuitive way

$films = TableRegistry::get('Films')->find('highestRated')
->select(['id'])
->limlt(3);

$query = $related->find()
->where(['id' => $films]);

Subqueries are accepted anywhere a query expression can be used. For example, in the select() and join() methods. http://book.cakephp.org/3.0/en/orm/query-builder.html#subqueries
