Cakephp错误：未在项目上定义图像关联

我有一个带有“ProjectsManager”插件的CakePHP应用程序

src/Model/Table/ImagesTable.php：

public function initialize(array $config)
{
    ...
    $this->belongsToMany('ProjectsManager.Projects', [
        'className' => 'ProjectsManager.Projects',
        'foreignKey' => 'image_id',
        'targetForeignKey' => 'project_id',
        'joinTable' => 'images_projects'
    ]);

public function initialize(array $config)
{
    ...
    $this->hasMany('Images', [
        'className' => 'Images',
        'foreignKey' => 'project_id',
        'targetForeignKey' => 'image_id',
        'joinTable' => 'images_projects'
    ]);
    $this->hasOne('CoverImage', [
        'className' => 'Images',
        'bindingKey' => 'cover',
        'foreignKey' => 'id'
    ]);

    $this->paginate = [
        'fields' => ['Projects.title', 'Projects.slug', 'Projects.cover'],
        'conditions' => $where,
        'contain' => ['Images','CoverImage' => ['fields' => ['filename']]],
        'limit' => 15,
        'order' => ['id' => 'desc']
   ];

public function initialize()
{
    parent::initialize();
    $this->loadModel('ProjectsManager.Projects');
}

插件/ProjectsManager/src/Model/ProjectsTable.php：

public function initialize(array $config)
{
    ...
    $this->belongsToMany('ProjectsManager.Projects', [
        'className' => 'ProjectsManager.Projects',
        'foreignKey' => 'image_id',
        'targetForeignKey' => 'project_id',
        'joinTable' => 'images_projects'
    ]);

public function initialize(array $config)
{
    ...
    $this->hasMany('Images', [
        'className' => 'Images',
        'foreignKey' => 'project_id',
        'targetForeignKey' => 'image_id',
        'joinTable' => 'images_projects'
    ]);
    $this->hasOne('CoverImage', [
        'className' => 'Images',
        'bindingKey' => 'cover',
        'foreignKey' => 'id'
    ]);

    $this->paginate = [
        'fields' => ['Projects.title', 'Projects.slug', 'Projects.cover'],
        'conditions' => $where,
        'contain' => ['Images','CoverImage' => ['fields' => ['filename']]],
        'limit' => 15,
        'order' => ['id' => 'desc']
   ];

public function initialize()
{
    parent::initialize();
    $this->loadModel('ProjectsManager.Projects');
}

插件/ProjectsManager/src/Controller/Publica/projectscocontroller.php：

public function initialize(array $config)
{
    ...
    $this->belongsToMany('ProjectsManager.Projects', [
        'className' => 'ProjectsManager.Projects',
        'foreignKey' => 'image_id',
        'targetForeignKey' => 'project_id',
        'joinTable' => 'images_projects'
    ]);

public function initialize(array $config)
{
    ...
    $this->hasMany('Images', [
        'className' => 'Images',
        'foreignKey' => 'project_id',
        'targetForeignKey' => 'image_id',
        'joinTable' => 'images_projects'
    ]);
    $this->hasOne('CoverImage', [
        'className' => 'Images',
        'bindingKey' => 'cover',
        'foreignKey' => 'id'
    ]);

    $this->paginate = [
        'fields' => ['Projects.title', 'Projects.slug', 'Projects.cover'],
        'conditions' => $where,
        'contain' => ['Images','CoverImage' => ['fields' => ['filename']]],
        'limit' => 15,
        'order' => ['id' => 'desc']
   ];

public function initialize()
{
    parent::initialize();
    $this->loadModel('ProjectsManager.Projects');
}

所以，在我的控制器中，我想加载所有项目和相关的图像，看看上面的代码。运行此命令会导致错误：

未在项目上定义图像关联

因此，我一直在搜索和阅读，发现我需要前缀插件，使其工作。所以我做了代码中可以看到的事情。然而，错误依然存在

有什么想法吗？

经过一番尝试，我找到了解决办法

在应用程序控制器（例如ImagesController.php）中，当您使用

$this->Images->……

时，它会工作。使用该代码，将调用ImagesModel

在插件内部，这不起作用。。。或者至少，ProjectsModel没有被调用

因此，我需要通过将以下代码添加到projectscoontroller.php，手动加载模型：

public function initialize(array $config)
{
    ...
    $this->belongsToMany('ProjectsManager.Projects', [
        'className' => 'ProjectsManager.Projects',
        'foreignKey' => 'image_id',
        'targetForeignKey' => 'project_id',
        'joinTable' => 'images_projects'
    ]);

public function initialize(array $config)
{
    ...
    $this->hasMany('Images', [
        'className' => 'Images',
        'foreignKey' => 'project_id',
        'targetForeignKey' => 'image_id',
        'joinTable' => 'images_projects'
    ]);
    $this->hasOne('CoverImage', [
        'className' => 'Images',
        'bindingKey' => 'cover',
        'foreignKey' => 'id'
    ]);

    $this->paginate = [
        'fields' => ['Projects.title', 'Projects.slug', 'Projects.cover'],
        'conditions' => $where,
        'contain' => ['Images','CoverImage' => ['fields' => ['filename']]],
        'limit' => 15,
        'order' => ['id' => 'desc']
   ];

public function initialize()
{
    parent::initialize();
    $this->loadModel('ProjectsManager.Projects');
}

你必须添加插件前缀在你有很多关联调用插件的模型表文件。有关详细信息，请参阅此链接。@Ishanvyas2，我在ImageTable.php中这样做了。如果我要将其添加到ProjectsTable中，我如何引用“main”应用程序？
