I am using paperclip to upload images. I have noticed that when uploading images which do not have a file extension, it shows as a link to the image (list, show, edit) and not the image itself.
The image shows normally in the app however.
I would appreciate a fix for this or at least a workaround for the time being.
Fixes issue #1446 by checking file type with filemagic gem.
You could do:
field :photo do
to force photos to be shown as image.
