Question

所以我有一个Users表和一个Security Questions表。我能够创建一个具有相关安全问题的用户，但是当我查看配置文件时，我无法正确显示displayField。

这是UsersTable.php的代码

public function initialize(array $config)
{
    parent::initialize($config);

    $this->table('users');
    $this->displayField('email');
    $this->primaryKey('id');
    $this->hasOne('SecurityQuestions',
        [ 'foreignKey' => 'security_question_id']);

    $this->addBehavior('Timestamp');
}

以下是SecurityQuestionsTable.php的代码

    public function initialize(array $config)
{
    parent::initialize($config);

    $this->table('security_questions');
    $this->displayField('question');
    $this->primaryKey('security_question_id');

    $this->hasMany('Users', ['foreignKey'=>'security_question_id', 'bindingKey'=>'security_question_id']);
    $this->belongsTo('SecurityQuestions', [
        'foreignKey' => 'security_question_id',
        'joinType' => 'INNER'
    ]);
}

这是我的UsersController.php视图方法：

    public function view($id = null)
{
    $user = $this->Users->get($id, [
        'contain' => []
    ]);

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

最后但并非最不重要的是，视图代码

<h3><?= h($user->id) ?></h3>
<table class="vertical-table">
    <tr>
        <th><?= __('Email') ?></th>
        <td><?= h($user->email) ?></td>
    </tr>
    <tr>
        <th><?= __('Password') ?></th>
        <td><?= h($user->password) ?></td>
    </tr>
    <tr>
        <th><?= __('First Name') ?></th>
        <td><?= h($user->first_name) ?></td>
    </tr>
    <tr>
        <th><?= __('Last Name') ?></th>
        <td><?= h($user->last_name) ?></td>
    </tr>
    <tr>
        <th><?= __('Id') ?></th>
        <td><?= $this->Number->format($user->id) ?></td>
    </tr>
    <tr>
        <th><?= __('Created') ?></th>
        <td><?= h($user->created) ?></td>
    </tr>
    <tr>
        <th><?= __('Expiration') ?></th>
        <td><?= h($user->expiration) ?></td>
    </tr>
    <tr>
        <th><?= __('User Status') ?></th>
        <td><?= h($user->user_status) ?></td>
    </tr>
    <tr>
        <th><?= __('Security Question') ?></th>
        <td><?= h($user->security_question_id) ?></td>
    </tr>
    <tr>
        <th><?= __('Security Question Answer') ?></th>
        <td><?= h($user->security_question_answer) ?></td>
    </tr>
</table>

Answer 1

你需要改变一些小事。

在您的UsersTable中：

$user = $this->Users->get($id, [
    'contain' => []
]);

需要

$user = $this->Users->get($id, [
    'contain' => ['SecurityQuestions']
]);

在您的视图文件中：

<tr>
    <th><?= __('Security Question') ?></th>
    <td><?= h($user->security_question_id) ?></td>
</tr>

需要

<tr>
    <th><?= __('Security Question') ?></th>
    <td><?= h($user->security_question->question) ?></td>
</tr>

显示字段主要用于创建下拉列表，以及一些构建脚手架视图的插件（如crud-view）。

CakePHP 3.0关联不显示另一个模型的displayField
