Symfony2：EasyAdminbundle + StofDoctrineExtensionsBundle + VichUploaderBundle

Question

我有一個使用EasyAdminBundle進行管理的項目。在一個名爲「發佈」的實體中，我有「標題」，「圖片」和「發佈」字段，我希望跟蹤有關更改。屬性「image」只存儲​​圖像的文件名 - 完整的上傳過程由VichUploaderBundle管理。

如何/我在哪裏可以篩選舊圖像文件在更改時不會被刪除，因爲它將用於歷史記錄？

當你定義的映射，有一種方法來告訴VichUploaderBundle，它不應該自動刪除舊文件：

這裏是從包的文檔抽取的樣本映射配置：

vich_uploader: 
    db_driver: orm 
    mappings: 
     product_image: 
      uri_prefix:   /images/products 
      upload_destination: %kernel.root_dir%/../web/images/products 
      inject_on_load:  false 
      # this prevents the file from being deleted on update 
      delete_on_update: false 
      # this prevents the file from being deleted when the 
      # entity itself is deleted 
      delete_on_remove: true
