Symfony2：EasyAdminbundle + StofDoctrineExtensionsBundle + VichUploaderBundle

Question

我有一个使用EasyAdminBundle进行管理的项目。在一个名为＆＃34; Post＆＃34;我有字段＆＃34;标题＆＃34;，＆＃34;图像＆＃34;和＆＃34;发布＆＃34;我想追踪变化。该物业＆＃34;图像＆＃34;只存储图像的文件名 - 完整的上传过程由VichUploaderBundle管理。

如何/在哪里可以对旧图像文件在更改时不会被删除进行网格划分，因为它将用于历史记录？

Answer 1

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：

以下是从软件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
