CakePHP 3无法保存关联的模型 [英] CakePHP 3 cannot save associated model

问题描述

我正在更新某些表中的某些日志数据。我无法在关联的模型ModulesEmployees上仅保存顶级CoursesEmployees。不能看到缺少的内容。

I am updating some log data in some tables. I can't save on the associated model ModulesEmployees only the top level CoursesEmployees. Cant see what is missing.

CoursesEmployeeTable.php

CoursesEmployeeTable.php

    $this->hasMany('ModulesEmployees', [
        'dependent' => true,
        'foreignKey' => 'courses_employee_id'
    ]);

ModulesSlidesController.php

ModulesSlidesController.php

$this->loadModel('CoursesEmployees');

$CoursesEmployee = $this->CoursesEmployees
     ->get(65, [
           'contain' => ['ModulesEmployees'],
           'where' =>[
                ['ModulesEmployees.id' => 19]
            ]
        ]);

if (!$CoursesEmployee['modules_employees'][0]['started_on']) {
    $CoursesEmployee['modules_employees'][0]['started_on'] = date('Y-m-d H:i:s');
};

$this->CoursesEmployees->save($CoursesEmployee, ['associated' => ['ModulesEmployees']]);

推荐答案

仅保存脏的实体/属性，并且您在此所做的修改嵌套实体的操作只会标记该嵌套实体作为d不幸的是，父实体 CoursesEmployee 将保持不变，因此保存过程不会触及关联。

Only dirty entities/properties are being saved, and what you are doing there, modifying a nested entity, will only mark that nested entity as dirty, the parent entity, CoursesEmployee will remain unchanged, and therefore the saving process won't touch the associations.

不使用自动将父实体属性标记为脏的修补机制时，则必须自己完成。

When not using the patching mechanism which automatically marks parent entity properties as dirty, then you'll have to do that on your own.

从文档中引用：

[...]

[...]

如果要在构建后构建或修改关联数据您的
实体，您将必须使用dirty（）将关联属性标记为已修改的
：

If you are building or modifying association data after building your entities you will have to mark the association property as modified with dirty():

$company->author->name = 'Master Chef';
$company->dirty('author', true);

菜谱>数据库访问& ORM>保存数据>保存关联

Cookbook > Database Access & ORM > Saving Data > Saving Associations

因此，在您的情况下，它是 modules_employees 需要标记为脏的属性，例如

So in your case it's the modules_employees property that needs to be marked as dirty, like

$CoursesEmployee->dirty('modules_employees', true);
