我正在使用AWS S3进行图像存储,并且Rails应用程序具有确认视图。但是在我的上传图片中(创建操作之前)未显示在我的确认视图中。然后,我尝试将Refile gem添加到我的应用程序中以使用S3的缓存,但是效果不佳。那么如何使Refile适应我的应用程序。
我正在使用Rails 5.1.6.1。在适应Refile之前,我使用的是Carrierwave,我认为它们具有相同的功能,所以我不知道如何使用Carrierwave适应Refile。在阅读正式文件Refile时,我发现image列的名称已更改为image_id,因此我制作了将文件更改为image_id的迁移文件,但它根本不起作用。

我希望删除carrierwave.rb并将refile.rb制作到/ config / initializer。但是我不确定如何编写连接S3存储桶的方法。
这是我通过stackoverflow提出的第一个问题,如果您对此一无所知,很抱歉。
