Question

我正在使用Cakephp 3而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HasMany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我的相关个人资料，

想象一下，如果我为该特定用户拥有10000个配置文件，那么很难显示所有1000个配置文件，我如何为它们分页？

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10000记录它将在视图模板上没有分页可用，这真的很难加载页面甚至读取所有，

这是我的观点

<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>

请帮忙，谢谢

Answer 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：）

Answer 2

也许这就是你要找的东西：

控制器操作中的
：

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

Answer 3

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UserProfiles

class UserProfilesTable extends Table {

    public function initialize(array $config) {

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

<强> UserController中

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; ?>  <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>
