[DDC-2220] Add joins to Collection Filtering API

Thu, 3 Jan 2013 20:21:21 +0000

The recently added collection filtering API only goes half way in achieving a full fledged solution to filter huge collections. It still lacks joins. Look at the next two snippets:

    $criteria = Criteria::create()
        ->where(Criteria::expr()->eq('storeId', $store->getId()))
        ->andWhere(Criteria::expr()->eq('Category', 20))
        ->orderBy(array('popularity' => 'DESC'));
    return $this->BrandCategories->matching($criteria);

This piece of code works but what if there is a need to filter the BrandCategories collection by Categories with some extra criteria:

    $criteria = Criteria::create()
        ->where(Criteria::expr()->eq('storeId', $store->getId()))
        ->andWhere(Criteria::expr()->eq('Category', 20))
        ->andWhere(Criteria::expr()->eq('Category.name', 'Electronics'))
        ->orderBy(array('popularity' => 'DESC'));
    return $this->BrandCategories->matching($criteria);

That would not work.

Ideally we should have a possibility to join other entities, the Category entity in our case here:

    $criteria = Criteria::create()
        ->where(Criteria::expr()->eq('storeId', $store->getId()))
        ->andWhere(Criteria::expr()->eq('Category', 20))
        ->innerJoin(Criteria::expr()->field('Category', 'Category'))
        ->andWhere(Criteria::expr()->eq('Category.name', 'Electronics'))
        ->orderBy(array('popularity' => 'DESC'));
    return $this->BrandCategories->matching($criteria);

What do you think about it, does it make sense to add such functionality?
