假设我有21条记录
我的观点显示每页10条记录
现在我在页面上:3,然后我删除了一条记录并刷新页面
蛋糕将显示未找到错误
如何转到第2页(最后一页),而不是显示错误消息?
我检查了PaginatorComponent.php 它只是抛出一个NotFoundException
if ($requestedPage > $page) {
throw new NotFoundException();
}

根据Manual,您必须捕获异常并重定向到右侧页面

虽然我不一定对此感到满意,但这是我的所作所为。
try {
$this->Paginator->settings = $this->paginate;
$widgets = $this->paginate();
} catch (NotFoundException $e) {
//Redirect to previous page
$query = $this->request->query;
$query['page']--;
extract(Router::parse($this->request->here));
$pass = empty($pass) ? '' : $pass[0];
$this->redirect(array_merge(array('action' => $action, $pass), array('?' => $query)));
}
正如您所看到的,我在查询字符串中递减页码并保持重定向,直到我到达有效页面。我无法找到直接到最后一页的已知页数。此外,我不满意提取URL的部分只是为了重建它。在我的情况下,$ pass参数可能存在也可能不存在,这就是我进行空检查的原因。虽然这有效,但我欢迎有关如何做得更好的想法。

我所做的是在捕获NoFoundException时获取上一页,但是通过命名的params:
try {
$records = $this->Paginator->paginate();
} catch (NotFoundException $e) {
$this->request->params['named']['page']--;
$records = $this->Paginator->paginate();
}
我认为最好只覆盖paginator组件。

这有效:
```的PHP class PaginatorComponent扩展了CorePaginatorComponent {
/**
* Overwrite to always redirect from out of bounds to last page of paginated collection.
* If pageCount not available, then use first page.
*
* @param \Cake\Datasource\RepositoryInterface|\Cake\Datasource\QueryInterface $object The table or query to paginate.
* @param array $settings The settings/configuration used for pagination.
*
* @throws \Cake\Network\Exception\NotFoundException
*
* @return \Cake\Datasource\ResultSetInterface Query results
*/
public function paginate($object, array $settings = [])
{
try {
$resultSet = parent::paginate($object, $settings);
} catch (NotFoundException $exception) {
$query = null;
if ($object instanceof QueryInterface) {
$query = $object;
$object = $query->repository();
}
$alias = $object->alias();
$lastPage = $this->request->params['paging'][$alias]['pageCount'] > 1 ? $this->request->params['paging'][$alias]['pageCount'] : null;
$response = $this->getController()->redirect(['?' => ['page' => $lastPage] + $this->request->getQuery()]);
// To be please PHPCS and tests, cannot be reached in production.
if (PHP_SAPI === 'cli') {
throw new NotFoundException('Redirect to ' . $response->getHeaderLine('Location') . ' for non-CLI.');
} else {
$response->send();
}
exit();
}
return $resultSet;
}
} ```
只需将其放入您的项目中,它将自动使用而不是核心项目。 适用于< = 3.4(第一页)和3.5+(最后一页)。
