doctrine extra lazy load doesn't work as expected with count

Question

I have an entity Shop and a related entity ShopProduct, with the following relation:

/**
 * @OR         


        

Answer 1

Just encountered the same problem and the solution was very simple:

{{ value.getAlerts.count() }}

instead of

{{ value.getAlerts.count }}

Twig must be overriding the Doctrine count() method meant to "Extra Lazy Load" with a variant of it's own implementation that just dumbly fetches all entities to count them.

That turned all expected SELECT * queries into COUNT(*)...
