数据库中的映像_名称始终为空vichuploaderbundle symfony2

我正在尝试使用图像文件添加新用户。我正在使用和。因此，创建了新用户，但image_name始终为空

这是我的图像实体：

在我的数据库中，列image\u name处有一个空值。如何解决此问题？

您应该在图像实体中添加一个映射字段（例如updatedAt）。使用方法setImageFile设置映像时，还应更新映射字段以触发事件侦听器并处理上载的文件

image_name仍然获得空值请确保在更改代码后更新了架构（“应用/控制台原则：架构：更新-强制”或使用迁移）并清除了应用程序缓存。对于corse，但它仍然获得空值OK，让我们再次检查。您已将updatedAt字段添加到Image类中，并使用if（$Image）{$this->updatedAt=new\DateTime（'now'）；}修改了setImageFile方法。对吗？另外，请检查您是否在config.yml中设置了上载映射。如果可能，请使用config.yml文件中的映射设置更新您的问题。只需将config.yml中的映射名称和图像实体更改为一些中性名称，如“图像”。但在这种情况下，所有图像（用于所有相关实体）都将上载到一个存储器中。如果您想为各种实体分离目录，只需删除图像实体并将vichuploader字段添加到实体中，并对eacn实体使用单独的映射即可。
