What if the files aren’t image files? I see the attributes in the migration are all image-related… is this only for image files?

Not to nitpick, but this is image scaling, not cropping. I’m looking for an example of cropping (cut out a rectangular portion of an image).

In some cases you’d want to pass the :style of photo into the exists?() method since some transformed versions of the original photo might not have been produced during upload.

e.g.

I also had trouble with the plugin. it left an empty “paperclip” folder in my plugins dir.

“gem install paperclip” did the trick

sorry, there was a typo… it should be

has_attached_file :photo

for this example.

Instead of typing out all of that code for the migration you can use

ruby script/generate paperclip event photo

then rake the DB as usual. As for the model, you can add some extra spice by setting the path/urls for the storage (very useful if your using subdomain assets). You can also set a default picture with the default_url which removes the "missing" text and replaces it with an image.

has_attached_file :image, :styles => { :gallery => "180x180>", :thumbnail => "100x100>"},
                    :url => "/assets/events/:id/:style/:basename.:extension",
                    :path => ":rails_root/public/assets/events/:id/:style/:basename.:extension",
:default_url => "/assets/events/default.jpg"
