更新
所以我在 ProductsController 中的 action upload 和 MediasTable 中的方法 upload 中添加了一些日志,以了解发生了什么。ProductsController 中的实体this->Products->Medias->newEntity()
已传递给 MediasTable,但未保存。
是否需要上传文件才能将数据保存在db中?就像如果所有数据都正常但文件不存在,事件将拒绝数据并且在数据库中什么都不做?
我正在使用带有文件存储插件的 cakephp 3.1。我正在遵循文档中的快速入门指南:快速入门,但我不了解某些部分并且不上传,插入数据库也不制作缩略图。
这是我的数据库:
CREATE TABLE products (
id INT AUTO_INCREMENT PRIMARY KEY,
product_name VARCHAR(255) NOT NULL,
quantity INT NOT NULL,
sold INT NOT NULL,
description VARCHAR(1000),
price DECIMAL(7,2) NOT NULL,
old_price DECIMAL(7,2) NOT NULL,
visited INT NOT NULL,
status INT NOT NULL,
created DATETIME,
modified DATETIME
);
CREATE TABLE media_types (
id INT AUTO_INCREMENT PRIMARY KEY,
name_media_type VARCHAR(255) NOT NULL,
created DATETIME,
modified DATETIME
);
CREATE TABLE medias (
id INT AUTO_INCREMENT PRIMARY KEY,
media_type_id INT NOT NULL,
product_id INT NOT NULL,
path VARCHAR(255) NOT NULL,
created DATETIME,
modified DATETIME,
FOREIGN KEY media_type_key (media_type_id) REFERENCES media_types(id),
FOREIGN KEY product_key (product_id) REFERENCES products(id)
);
媒体表:
...
use Burzum\FileStorage\Model\Table\ImageStorageTable;
class MediasTable extends ImageStorageTable {
public function initialize(array $config) {
parent::initialize($config);
$this->table('medias');
$this->displayField('id');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsTo('MediaTypes', [
'foreignKey' => 'media_type_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Products', [
'foreignKey' => 'product_id',
'joinType' => 'INNER'
]);
}
...
public function upload($productId, $entity) {
$media = $this->patchEntity($entity, [
'adapter' => 'Local',
'model' => 'Media',
'foreign_key' => $productId
]);
Log::write('debug', $media);
return $this->save($media);
}
}
产品表:
class ProductsTable extends Table {
public function initialize(array $config) {
parent::initialize($config);
$this->table('products');
$this->displayField('id');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->hasMany('Medias', [
'className' => 'Medias',
'foreignKey' => 'foreign_key',
'conditions' => [
'Medias.model' => 'Media'
]
]);
}
...
}
产品控制器:
class ProductsController extends AppController {
public function upload($productId = null) {
$productId = 2;
$entity = $this->Products->Medias->newEntity();
if ($this->request->is(['post', 'put'])) {
$entity = $this->Products->Medias->patchEntity(
$entity,
$this->request->data
);
if ($this->Products->Medias->upload($productId, $entity)) {
$this->Flash->set(__('Upload successful!'));
}
}
$this->set('productImage', $entity);
}
...
}
在 config/local_store.php 中与示例相同(我将此文件包含在 boostrap.php 中)
...
$listener = new LocalFileStorageListener();
EventManager::instance()->on($listener);
$listener = new ImageProcessingListener();
EventManager::instance()->on($listener);
Configure::write('FileStorage', [
'imageSizes' => [
'Medias' => [
'large' => [
...
]);
FileStorageUtils::generateHashes();
StorageManager::config('Local', [
'adapterClass' => '\Gaufrette\Adapter\Local',
'adapterOptions' => [TMP, true],
'class' => '\Gaufrette\Filesystem'
]);
上传.ctp
echo $this->Form->create($productImage, array('type' => 'file'));
echo $this->Form->file('file');
echo $this->Form->error('file');
echo $this->Form->submit(__('Upload'));
echo $this->Form->end();
在快速入门中有两种上传方法:uploadImage 和 uploadDocument,但在控制器中它们使用“上传”。
示例中 Products 中还有另一个关联,我需要这个吗?:
$this->hasMany('Documents', [
'className' => 'FileStorage.FileStorage',
'foreignKey' => 'foreign_key',
'conditions' => [
'Documents.model' => 'ProductDocument'
]
]);
我发现了这个问题(从那里我正在使用的数据库)开始使用 cakephp-file-storage 快速入门指南并上传和插入但不制作缩略图,如果我将表更改为 ImageStoreTable 显示错误“类不是成立”
因此,如果有人可以帮助我,我将不胜感激!
