php - CakePHP 节省约定

Question

我在一个模型上建立了一个关系，其中 primaryKey 设置为“Document.guid”，同时我还有一个关联的模型 DocumentVersion。

class Document extends DocumentAppModel {

public $hasMany = array(    
    'DocumentVersion' => array(
        'className' => 'DocumentVersion',
        'foreignKey'  => false,
        'finderQuery' => 'SELECT * FROM document_versions as `DocumentVersion` WHERE `DocumentVersion`.`document_guid` = {$__cakeID__$} ORDER BY `DocumentVersion`.`version` DESC LIMIT 1'
     )
);

class DocumentVersion extends DocumentAppModel {
    public $belongsTo = array(
       'Document' 
    );
}

当我尝试使用 $this->Document->saveAll() 时，它只保存文档数据而不保存相关数据。根据我的理解，这与我没有使用 cakephp 约定来建立关联这一事实有关。

我的数据结构

            $filtered[] = array(
                'Document' => array(
                    'guid' => $upload['guid'],
                    'database_revision' => Configure::read('Settings.LocalDataBaseRevision')
                ), 
                'DocumentVersion' => array(
                     array(
                        //'guid' => $upload['guid'],
                        'parent_guid' => (isset($upload['parent_guid'])) ? $upload['parent_guid'] : null,
                        'document_type_id' => $upload['type'],
                        'owner' => $upload['owner_id'],
                        'editor_id' => (isset($uplaod['editor_id'])) ? $uplaod['editor_id'] : null,
                        'title' => $upload['title'],
                        'crc' => (isset($upload['crc'])) ? $upload['crc'] : null,
                        'payload' => (isset($upload['payload'])) ? $upload['payload'] : null,
                        'database_revision' => Configure::read('Settings.LocalDataBaseRevision'),
                        'version' => 1 // Always set version number to 1 on uploads
                     )
                )
            );

Answer 1

1. 我忘记了模型关系中插件名称的前缀。

   public $hasMany = array(
       'Document.DocumentVersion' => array(
          'className' => 'DocumentVersion',
          'foreignKey'  => false,
          'finderQuery' => 'SELECT * FROM document_versions as `DocumentVersion` WHERE `DocumentVersion`.`document_guid` = {$__cakeID__$} ORDER BY `DocumentVersion`.`version` DESC LIMIT 1'
        ));
   

2. 此时我仍然遇到同样的问题，但我最终通过在我的保存方法中使用深度关联解决了这个问题。

   $this->Document->saveAll($data, array('deep' => true));
