Question

这个问题可能重复。但我对一些问题和教程感到困惑。

我尝试使用以下代码保存数组。

$data = array(
    'name' => 'ques 1',
    'description' => 'lskjdf sldkfj sdlfkjsd flskdjf sldkfjsd',
    'objective' => 'jd ldkjf sldkf sldfj sdlfjdlsfsjfl ds',
    'Question' => array(
        'type' => 'BOOLEAN',
        'body' => 'slkdjfs dflskdf slkfjsiuwsdjkf sd',
        'Answer' => array(
            'body' => 'sd fsldkjfs dddd ddd ddd'
        ),
    ),
);

$this->Questionnaire->create();
$this->Questionnaire->saveAll($data);

运行后，此代码问卷已保存3个问题，但没有任何答案。只有一个问题具有身体价值。

这是我的模特课。

Questionnaire.php

<?php
App::uses('AppModel', 'Model');

/**
 * Questionnaire Model
 */
class Questionnaire extends AppModel {

    /**
     * Validation rules
     *
     * @var array
     */
    public $validate = array(
        'name' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Name is required'
            )
        ),
        'description' => array(

        ),
        'objective' => array(

        ),
    );

    public $hasMany = array(
        'Question' => array(
            'className' => 'Question',
            'foreignKey' => 'questionnairy_id'
        ),
    ); 

}

Question.php

<?php
App::uses('AppModel', 'Model');

/**
 * Question Model
 */
class Question extends AppModel {

    /**
     * Validation rules
     *
     * @var array
     */
    public $validate = array(
        'type' => array(
            'valid' => array(
                'rule' => array('inList', array(
                    BOOLEAN_ANSWER, 
                    SINGLE_ANSWER, 
                    MULTIPLE_ANSWER, 
                )),
                'message' => 'Invalide type',                
            )
        ),
        'body' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Question is required'
            )
        ),      
    );

    public $belongsTo = array(
        'Questionnaire' => array(
            'className' => 'Questionnaire',
            'foreignKey' => 'questionnaire_id'
        ),
    ); 

    public $hasMany = array(
        'Answer' => array(
            'className' => 'Answer',
            'foreignKey' => 'question_id'
        ),
    ); 

}

Answer.php

<?php
App::uses('AppModel', 'Model');

/**
 * Answer Model
 */
class Answer extends AppModel {

    /**
     * Validation rules
     *
     * @var array
     */
    public $validate = array(
        'body' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Answer is required'
            )
        ),      
    );

    public $belongsTo = array(
        'Question' => array(
            'className' => 'Question',
            'foreignKey' => 'question_id'
        ),
    ); 

}

我需要知道保存这个数组的正确方法。请帮我。

Answer 1

您需要正确格式化阵列。 $data数组应如下所示：

array(
  'Questionnaire' => array(
    'name' => 'Questionnaire 1'
  ),
  'Question' => array(
    array(
      'type' => 'BOOLEAN',
      'body' => 'Is Cake sweet?',
      'Answer' => array(
        array(
          'body' => 'Yes.'
        )
      )
    ),
    array(
      'type' => 'BOOLEAN',
      'body' => 'Does Cake make things easy and fast?',
      'Answer' => array(
        array(
          'body' => 'Yes.'
        )
      )
    ),
  )
);

请注意，Question位于索引数组中（与Answer相同）。这是因为他们的关系是hasMany。

表单看起来像这样：

$this->Form->create('Questionnaire');
$this->Form->input('Questionnaire.name');
$this->Form->input('Question.0.type');
$this->Form->input('Question.0.body');
$this->Form->input('Question.0.Answer.0.body');
$this->Form->input('Question.1.type');
$this->Form->input('Question.1.body');
$this->Form->input('Question.1.Answer.0.body');
$this->Form->end();

最后，你需要告诉Cake保存时继续：

$ this-＆gt;调查问卷 - ＆gt; saveAll（$ data，array（'deep'=＆gt; true））;
