doctrine2查找方法返回数组而不是ArrayCollection

Question

I have a problem with Doctrine2 find methods. They all return as array instead of ArrayCollection.

Is there any away to force them to return a ArrayCollection? I remember this also happened with a custom repository query. I had to do: new ArrayCollection($result).

Answer 1

Here is my dirty, low-tech approach.

// your findBy* here:
$entities = $em->getRepository($entclass)->findBy($entFilter, array('id' => 'DESC'));

// my one-liner conversion here:
$entitiesCollection= new \Doctrine\Common\Collections\ArrayCollection($entities);

Then I confirmed I could use those handy ArrayCollection methods like last(), count(), contains(), etc.

var_dump($entitiesCollection->count(), $entitiesCollection); print \strftime('%c') . __FILE__ . __LINE__ . __FUNCTION__; die;
