使用Paperclip将图像从数据库下载到项目文件夹

Question

I want to download an image stored in database with paperclip and put it in my project folder. In app/assets/images for example.

Why? : Because I want to put image in a Word. So when I use docx_replace or caracal gem I cant put directly image within the variable from database (that don't work). But I can put image directly from folder. So I want to put the image from DB to folder, put in the Word and delete it after insertion. That's why. But if you have another technique tell me.

Do you now a way in order to do that ?

Answer 1

As you store your files locally and paperclip provides helpers to the full path of the file, you can just use Ruby FileUtils to copy the file to the public directory in your action. You don't need to download it, because it is already in the filesystem.
