我如何在 cakephp 3 中为相关数据创建分页答案

【问题标题】：how i can create pagination for related data in cakephp 3我如何在 cakephp 3 中为相关数据创建分页
【发布时间】：2023-04-10 22:00:01
【问题描述】：

我正在使用 Cakephp 3，我正在尝试为相关数据创建分页，换句话说，所有记录都属于第一个表。

示例

我有两张桌子

用户
User_Profiles

用户有很多个人资料，所以当我点击任何用户时，它会在查看功能中显示相关的个人资料，

想象一下，如果我有 10000 个特定用户的个人资料，那么很难显示所有 1000 个个人资料，我如何为他们分页？

这是我的控制器

public function view($id = null)
{
    $distributor = $this->Distributors->get($id, [
        'contain' => ['DistributorUsers', 'Participants', 'Payments']

    ]);

    $this->set('distributor', $distributor);
    $this->set('_serialize', ['distributor']);
}

从该函数我们可以看到我们有 3 个表是相关的，如果我在每个表上都有 10000 条记录，它将在视图模板上可用而无需分页，这真的很难加载页面甚至阅读所有内容，

这是我的看法

<table class="table table-condensed table-hover">
        <thead>
                        <tr>
                            <th colspan="3"> <?= h($distributor->name) ?> </th>
                        </tr>
         </thead>

     <tbody>
        <tr>
            <td><?= __('Name') ?></th>
            <td><?= h($distributor->name) ?></td>
        </tr>
        <tr>
            <td><?= __('Location') ?></th>
            <td><?= h($distributor->location) ?></td>
        </tr>

请帮忙，谢谢

i have two tables 您的代码使用完全不同的名称 - 请描述您的实际问题，而不是简化版本 - 即使描述与问题中的代码一致。

【解决方案1】：

在你的情况下：

public function view($id = null){
    $limit = 10; //limit 10 record for each assosiation
    $this->paginate = [
        'DistributorUsers' => function ($q){ return $q->limit($limit); },
        'Participans' => function ($q){ return $q->limit($limit); },
        'Payments' => function ($q){ return $q->limit($limit); }
    ];
    $distributor = $this->paginate($this->Distributors);
    $this->set('distributor', $distributor);
    $this->set('_serialize', ['distributor']);
}

我希望这能解决你的问题:)

【解决方案2】：

试试这个：

模型用户

class UsersTable extends Table {

    public function initialize(array $config) {

        $this->hasMany('UserProfiles', array(
           'foreignKey' => 'user_id'  
        ));
    }
}

模型用户配置文件

class UserProfilesTable extends Table {

    public function initialize(array $config) {

        $this->belongsTo('Users', [
            'foreignKey' => 'user_id',
        ]);
    }
}

用户控制器

public function view($id = null) {

    if(is_null($id)) {
        $id = $this->request->param('id');
    }

    //Get User
    $user = $this->Users->get($id);

    //Get Paginated User Profiles by User id
    $this -> paginate['contain'] = ['Users'];
    $this -> paginate['conditions'] = ['UserProfiles.user_id =' => $id];
    $this -> paginate['limit'] = 8;
    $this -> paginate['order'] = ['UserProfiles.created' => 'desc'];

    //Url paginator e.g.: /user/153/?page=2
    $paginateUrl = ['id'=> $this->request->param('id')];

    /*If you use slugs in your route*/
    //Url paginator e.g.: /user/153/userSlug.html?page=2
    //$paginateUrl = ['id'=> $this->request->param('id'), 'slug' => $this->request->param('slug')];

    $this->set(compact('paginateUrl'));
    $this->set('UserProfiles', $this->paginate($this->UserProfiles));
    $this->set(compact('user'));
}

查看

<?php foreach($userProfiles as $userProfile): ?>
    ...
<?php endforeach; ?> 

<!-- Pagination -->
<div class="row text-center">
    <div class="col-lg-12">
        <ul class="pagination">
            <?= $this->Paginator->options(['url' => $paginateUrl])?>
            <?= $this->Paginator->prev('< ' . __('previous')) ?>
            <?= $this->Paginator->numbers() ?>
            <?= $this->Paginator->next(__('next') . ' >') ?>
        </ul>       
    </div>
</div>
<!-- /.Pagination -->

【解决方案3】：

也许这就是你要找的东西：

在控制器动作中：

$assosiationLimit = 10 //limit display data for User Profile
$this->paginate = [
     'contain' => [
          'UserProfiles' => function($q){
               return $q->limit($assosiationLimit);
          }
     ]
];
$users = $this->paginate($this->Users);

【讨论】：

对不起，我不明白我应该把这个放在哪里？在我的控制器中查看我的视图功能
> 在您的情况下： public function view($id = null){ $limit = 10; //每个关联限制 10 条记录 $this->paginate = [ 'DistributorUsers' => function ($q){ return $q->limit($limit); }, '参与者' => function ($q){ return $q->limit($limit); }, '支付' => function ($q){ return $q->limit($limit); } ]; $distributor = $this->paginate($this->Distributors); $this->set('distributor', $distributor); $this->set('_serialize', ['distributor']); } 我希望这能解决你的问题 :)
