Rails-如何将回形针模型移动到另一个模型

Question

Rails 3 app with paperclip.

Given a Paperclip File Model, how can you move that paperclip File to different paperclip, say image gallery? Which would have different processing rules etc?

Any ideas?

Answer 1

I've just tried the following:

Given two models, with a picture attachment and their own Paperclip configurations, say: Gallery1 and Gallery2.

Given I had one object in Gallery1 with a picture already attached.

Make:

Gallery2.create(:picture => Gallery1.first.picture)

And it creates the picture properly resized with the constraints of Gallery2.
