items empty in getPaginate()

When attempting to present data with a filter on the data. Items are empty when displayed on view:

This is how im getting the result set:

$vehicles = Vehicles::find(array($vehicleWhere));

$paginator = new Paginator(array(
            "data" => $vehicles,
            "limit" => 10,
            "page" => $numberPage
        ));

This is a vardump of the $vehicles, $numberPage, and $page.

Which adapter you use as Paginator class? If you want to use resultset as data, then you should use \Phalcon\Paginator\Adapter\Model

More info: http://docs.phalconphp.com/en/latest/reference/pagination.html#adapters-usage

That is the Adapter I am using:

use Phalcon\Paginator\Adapter\Model as Paginator;

Hey,

sorry for injecting to your topic.

I've the same problem. Did you solved it? May you can share your experience with me?

Thanks a lot OP =)

Try using the Builder, see below,

Here is what I do:


    \Phalcon\Mvc\Model\Transaction\Manager as TransactionManager;

    /**
     * @return void
     */
    public function indexAction()
    {
        $page = (int) $this->request->get("page");
        $page = (!$page) ? 1 : (int) $page;

        $builder = $this->modelsManager->createBuilder()
            ->columns('id, user_id, transaction_id, type, gateway, amount, created_at')
            ->from('Transaction') // Notice the capitalized model name
            ->orderBy('id');

        $paginator = new \Phalcon\Paginator\Adapter\QueryBuilder([
            "builder" => $builder,
            "limit"=> 50,
            "page" => $page
        ]);

        // Get the paginated results
        $page = $paginator->getPaginate();

        $this->view->setVars([
            'page' => $page,
        ]);
        $this->view->pick('admin/transaction');
    }
    {% for transaction in page.items %}
    ...
    <tr>
        <td>{{ transaction.id }}</td>
        <td>{{ transaction.user_id }}</td>
        <td>{{ transaction.transaction_id }}</td>
        <td>{{ transaction.type }}</td>
        <td>{{ transaction.gateway }}</td>
        <td>{{ transaction.amount }}</td>
        <td>{{ transaction.amount_after_discount }}</td>
        <td>{{ transaction.created_at }}</td>
    </tr>
    ...
    {% endfor %}

<ul class="pagination pagination-large">
       <l}><a href="{{ url('admin/transaction') }}"><span class="glyphicon glyphicon-fast-backward"></span></a></li>
       <li><a href="{{ url('admin/transaction') }}?page=<?= $page->before; ?>"><span class="glyphicon glyphicon-chevron-left"></span></a></li>
       <li><a href="{{ url('admin/transaction') }}?page=<?= $page->next; ?>"><span class="glyphicon glyphicon-chevron-right"></span></a></li>
       <li><a href="{{ url('admin/transaction') }}?page=<?= $page->last; ?>"><span class="glyphicon glyphicon-fast-forward"></span></a></li>
</ul>

This is fragment from my grid helper.


    public function setData(Builder $data)
    {
        $this->_data = $data;
        return $this;
    }

    public function getData()
    {
        return $this->_data;
    }

    public function loadData()
    {
        if (is_null($this->_paginator))
        {
            $currentPage = ($this->request->has('page')) ? (int)$this->request->get('page') : 1;

            $data = clone $this->getData();
            $data->columns(sprintf('count(%s.id) as total', $this->getName()));
            $total = $data->getQuery()->execute()->getFirst()->total;

            if ($currentPage > ceil($total / $this->getLimit()) || $currentPage < 1)
                $currentPage = 1;

            $paginator = new \Phalcon\Paginator\Adapter\QueryBuilder(
                array(
                    "builder" => $this->getData(),
                    "limit"=> $this->getLimit(),
                    "page" => $currentPage
                )
            );

            $this->_paginator = $paginator->getPaginate();
        }

        return $this->_paginator;
    }

    public function build()
    {
        return $this->viewSimple->render('blocks/grid/layout', array('grid' => $this, 'paginator' => $this->loadData()));
    }

Solve this problem. If you use code from base example:

$currentPage = (int) $_GET["page"];

The only problem is value of $currentPage. it will turn 0 for very first page (if $_GET['page'] is not defined). Thats why you receive empty array in $paginator->items

Use this construction:

$currentPage = ($this->request->has('page')) ? (int)$this->request->get('page') : 1;
