Capistrano删除回形针图像

由于某些原因，每次我限制从所有用户中删除所有图像时，Capistrano都会删除数据库中的所有图像。通常，我要做的就是用capistrano删除的相同图像重新填充数据库。我已经附上了deploy.rb文件，有人可以给我一些启示。

For some reason Capistrano deletes all the images in my database every time I cap all the images get removed from all the users. Typically what I have done is have to refill the databased with the same images that had been delete by capistrano. I've attached my deploy.rb file, can someone give me some insight.
