Symfony2: EasyAdminbundle + StofDoctrineExtensionsBundle + V

Question

我有一个使用 EasyAdminBundle 进行管理的项目。在一个名为"帖子"的实体中，我有"标题"，"图像"和"帖子"字段，我想跟踪有关更改的信息。属性"image"仅存储图像的文件名 - 完整的上传过程由VichUploaderBundle管理。

如何/在哪里可以网格化旧图像文件不会在更改时被删除，因为它将用于历史记录？

当你定义映射时，有一种方法可以告诉VichUploaderBundle它不应该自动删除旧文件：

以下是从捆绑包文档中获取的示例映射配置：

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
