我对VichUploader有一个非常奇怪的问题。
我有2个实体，其中一个VichUploader工作正常（下载实体） - 它将文件保存在目录中并将记录添加到数据库表。对于第二个实体（Offer），它不起作用 - 它显示Column 'file_name' cannot be null错误。如果我在fileName属性中添加了nullable参数，则会将记录添加到数据库表中但是使用NULL file_name（并且它不能将文件保存在目录中）。
我的config.yml
vich_uploader:
db_driver: orm
mappings:
download_file:
uri_prefix: /files/download
upload_destination: %kernel.root_dir%/../web/files/download
offer_file:
uri_prefix: /files/offer
upload_destination: %kernel.root_dir%/../web/files/offer
inject_on_load: false
delete_on_update: false
delete_on_remove: true

可能会发生这种情况，因为UploadableField注释引用了字段数据库名称，而不是模型名称（例如：file_name，而不是fileName），但我在一个工作示例中测试了这一点，一切都很顺利。另外VichUploaderBundle监听Doctrine事件，这意味着你需要更新实体的任何其他字段来触发文件的实际上传，最简单的方法是强制＆＃34;强制＆＃34;上传其在文件字段设置器上设置字段。这是一个例子：
public function setFile($file)
{
$this->file= $file;
if ($this->file) {
$this->update_date = new \DateTime();
}
return $this;
}
这非常有效，因为您可以确保在触发PrePersist或PreUpdate事件时上载并附加文件。您可以收听PreUpload和PostUpload事件并检查已处理的数据（这很容易通过Symfony提供的 dump 功能完成，Symfony＆gt; = 2.6）。希望这可以帮助你
