Pagination Sort in Cakephp 3.x

Question

In cakephp 3.x i can't do paginate order in a find

This is my controller:

//AgentsController.php
public function show()
{
    $agents = $this->Agents->find()
    $this->set('agents', $this->paginate($agents));
}

And here part of my view

//show.ctp
<!-- ....... -->
<table class="table table-striped">
   <thead>
      <tr>
        <th>
            <?php echo $this->Paginator->sort('full_name', 'Nome', array('escape' => false)); ?>
        </th>
        <th>
            <?php echo $this->Paginator->sort('username', 'Email', array('escape' => false)); ?>
        </th>
        <th>
            <?php echo $this->Paginator->sort('regions', 'Regioni', array('escape' => false)); ?>
        </th>
      </tr>
   </thead>
<!-- ....... -->

Where i wrong?

Answer 1

The Paginator will block any attempt of sorting by a column that does not exist in the primary table of the query you are using. In this case you have 2 options. The first option is changing the sort links to tell cake that the column belongs to a related table:

<?php echo $this->Paginator->sort('Users.full_name', 'Nome'); ?>

Or you can tell it in the component that sorting by a given set of columns is allowed:

$this->paginate = ['sortWhitelist' => ['full_name', 'username']]
