我有一个实体"评论","评论"可能有一个或多个图像相关联.我如何实现这一目标.

现在我有了这个(只有一张图片):

/**
 * @Assert\File(
 *     maxSize="1M",
 *     mimeTypes={"image/png", "image/jpeg"}
 * )
 * @Vich\UploadableField(mapping="comment_mapping", fileNameProperty="imageName")
 *
 * @var File $image
 */
protected $image;

提前致谢

我有一个1and1帐户,即时尝试使用symfony2.3和swift_mailer发送电子邮件,但这是不可能的.

我没有任何错误,我已经检查了symfony日志,但没有.

这是我的实现(在一个Action中):

$message = \Swift_Message::newInstance()
    ->setSubject('Hello Email')
    ->setFrom('test@domain.com')
    ->setTo('myuser@mydomain.com')
    ->addCc('other@mydomain.com')
    ->setBody( "test body" )
;
$mailer = $this->get('mailer');
$result = $mailer->send($message, $fails);

//$fails receive a empty array
//$result get value 1

这是配置:

swiftmailer:
    transport: smtp                  #i also try mail and sendmail
    host:      smtp.1and1.mx         #i also try smtp.1and1.es, auth.smtp.1and1.fr
    username:  someone@mydomain.net  #the complete email someone@mydomain.net(this account is active, i'm able to login in webmail...) 
    password:  mypass
    spool:     { type: memory }
    encryption: tls                  # i also try without this setting …

我有这个功能:

func functionX(collection []*interface{}) {
    ...
    response, err := json.MarshalIndent(collection, "", "  ")
    ...
}

我希望collection参数允许任何类型的数组,这就是为什么我尝试使用*interface {}但我收到的错误是这样的:

cannot use MyDataType (type []*model.MyDataType) as type []*interface {} in argument to middleware.functionX
