Is there any established way to display an image uploaded by attachment_fu before the model with which it is associated is actually saved? For instance, I have an Artwork model which has many images. I'd like to allow image uploads on the new artwork form to be displayed after they are uploaded but before the artwork is saved.
Thanks
I've figured out some of what I want to do here, so I can be more specific:
This create action adds each uploaded Image, then creates a thumnail of each and stores it in the @temp_thumb_data array.
def create @artwork = @current_user.artworks.new params[:artwork] params[:image_data].each do |file| @artwork.images << Image.new( :uploaded_data => file ) if file.size
0
end unless not params[:image_data]
@temp_thumb_data = @artwork.images.each do |image| image.with_image do |img| @temp_thumb_data << img.thumbnail(100, 100).to_blob end end ...
However it is stored as an encoded string and can thus not simply be displayed. The normal method would be to use send_data in another action, but I can't do that here because the uploaded file is not being persisted and would not be available to the other action.
Any ideas?
