Cakephp 3.x 中的分页排序

问题描述

在 cakephp 3.x 中我不能在 find 中做分页顺序

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

这是我的控制器:

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

这里是我的部分观点

//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>
<!-- ....... -->

我错在哪里?

推荐答案

分页器将阻止任何按您正在使用的查询的主表中不存在的列进行排序的尝试.在这种情况下，您有 2 个选择.第一个选项是更改排序链接以告诉 cake 该列属于相关表:

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'); ?>

或者您可以在组件中告诉它允许按给定的一组列进行排序:

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

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