Wrong count in twig loop when using Pagerfanta with DoctrineORMAdapter

[mahdirabie]

I'm using

$products = new Pagerfanta(new DoctrineORMAdapter($queryBuilder, true, null));
$products->setMaxPerPage(10);

And my twig looks like,

{% for product in products %}
     LENGTH = {{ loop.length }}
{% endfor %}

I have 200 products but on any page loop.length returns 200 instead of 10, that causes twig loop utils to break.

It seems the problem is from DoctrineORMAdapter or Pagerfanta class which does not return number of current page results as twig loop iterator expects.

What is the solution here? I can happily create a PR if you'd guide me.

{{ product.getNbResults() }} will give the amount of items on the current page.

Changing the functionality of the count() method to not return the total would be a BC break.

@sstok Another problem is that loop.last doesn't work as expected too. It is comparing current index (0,1,2,etc) with length (always 200).

A little (inelegant) hack:
{% set remainingItems = (items.getNbResults() - ((items.currentPage - 1) * items.maxPerPage)) %}

and inside loop:
{% if loop.index == remainingItems %}

Can't find another way to know when I'm in the last iteration.
