cakephp 2.5 和 3.0 之间的查找结果不同答案

【问题标题】：Different find results between cakephp 2.5 and 3.0cakephp 2.5 和 3.0 之间的查找结果不同

【问题描述】：

我正在将我的应用程序从 cakephp 2.5 迁移到 3.0，并且我正在执行 ->find() 方法，然后在控制器中循环遍历结果。但是，我在 3.0 中返回了不同的结果。我似乎得到了 cakephp 在进入数据库之前使用的查询设置，而不是结果。

EmployeesController.php

2.5 代码：

//Open courses
$options = array(
    'conditions' => array('Employee.id' => 1, 'CoursesEmployee.completed' => false),
    'limit' => 3
    );
$recentOpen = $this->CoursesEmployee->find('all', $options);
debug($recentOpen);

// get next module for each open course
foreach ($recentOpen as $key => &$value) {
    //do something
}

结果：

array(
(int) 0 => array(
    'CoursesEmployee' => array(
        'id' => '1',
        'employee_id' => '1',
        'course_id' => '1',
        'course_module_id' => '5',
        'progress' => '10',
        'modified' => '2014-12-16 22:40:42',
        'created' => '2014-11-18 00:00:00',
        'completed' => false
    ),
    'Employee' => array(
        'id' => '1',
        'user_id' => '1',
        'hotel_id' => '1',
        'name' => 'Keith Power',
        'email' => '',
        'surname' => 'Power',
        'employee_num' => '',
        'modified' => '2014-11-19 12:52:36',
        'created' => '2014-11-18 00:00:00'
    ),
    'Course' => array(
        'id' => '1',
        'name' => 'Manual Handling Training',
        'course_lenght' => '02:12:00'
    ),
    'CourseModule' => array(
        'id' => '5',
        'course_id' => '1',
        'name' => 'Module 5',
        'type' => 'video',
        'video_url' => '',
        'video_lenght' => '00:00:00'
    )
),
(int) 1 => array(
    'CoursesEmployee' => array(
        'id' => '3',
        'employee_id' => '1',
        'course_id' => '2',
        'course_module_id' => '5',
        'progress' => '100',
        'modified' => '2014-12-05 15:13:47',
        'created' => '2014-11-20 00:00:00',
        'completed' => false
    ),
    'Employee' => array(
        'id' => '1',
        'user_id' => '1',
        'hotel_id' => '1',
        'name' => 'Keith Power',
        'email' => '',
        'surname' => 'Power',
        'employee_num' => '',
        'modified' => '2014-11-19 12:52:36',
        'created' => '2014-11-18 00:00:00'
    ),
    'Course' => array(
        'id' => null,
        'name' => null,
        'course_lenght' => null
    ),
    'CourseModule' => array(
        'id' => '5',
        'course_id' => '1',
        'name' => 'Module 5',
        'type' => 'video',
        'video_url' => '',
        'video_lenght' => '00:00:00'
    )
  )
)

3.0 代码：

$this->loadModel('CoursesEmployees');

//Open courses
$options = [
    'conditions' => ['Employees.id' => 1, 'CoursesEmployees.completed' => false],
    'limit' => 3,
    'contain' => 'Employees'
];
$recentOpen = $this->CoursesEmployees->find('all', $options)->toArray();

debug($recentOpen);

但我没有得到预期的返回结果，实际值似乎包含在一个名为 properties 的数组中，没有提到关于访问属性的蛋糕书：

3.0.0 中是否需要另一个步骤。它在两者中都找到了两条记录，但是 3.0 的格式是如此不同，我不知道如何像在 2.5 中那样访问这些值来执行我的循环。

*****更新

按照建议，我已更新到 Cakephp 3.05。现在所有额外的属性都被隐藏了，我得到了对象形式的结果。我正在使用->toArray()，但它似乎并没有改变对象。

标签： cakephp cakephp-3.0

【解决方案1】：

您正在查看自定义格式的调试输出，而不是对象的逻辑表示（例如使用 var_dump() 来查看差异）。

直到最近，当通过 debug() 转储实体时，各种隐藏属性都变得可见，包括 $_properties 属性，它保存了可用属性及其值的映射。

您看到这个的事实意味着您的代码库已经过时，您应该更新它以查看新格式，其中不再显示嵌套的属性，并且“特殊”内容显示为 @ 987654326@: https://github.com/cakephp/cakephp/pull/6564

在任何情况下，只要访问 Cookbook 中描述的属性就可以了。

$recentOpen[0]->employee->name

另见Cookbook > Database Access & ORM > Entities > Accessing Entity Data

【讨论】：

谢谢，我已经更新了 cakephp，现在我得到了对象形式的结果。我已经阅读了 Cookbook，但我仍然很困惑我会如何使用 $entity-> 我试图替换 $this-> 但我确定这不是使用它的方式。
@KeithPower 抱歉，我不太明白您的问题。只需使用您的 $recentOpen 变量，对其进行迭代，或通过它们在数组中的索引直接访问实体对象，或者...我已经更新了示例。
完美，我仍然认为它是一个数组，而不是作为一个对象访问它->我现在可以遍历结果了，谢谢。

【解决方案2】：

在 2.5 代码中，您的条件是 Employee.id => 1，而您在 3.0 查询中的条件是 Employees.user_id => 1

【讨论】：

是的，你是对的，我在 3.0 中添加了 auth，所以我改为使用 user_id。我已经更新了代码以消除混淆。结果是一样的。
