Rails Load a icon which isn't saved in the images folder

Question

Hi,

I wand to give a preview of the just uploaded pictures. These pictures are not saved in the public folder, as they are not public...

How can I do this?

Thanks Markus

Answer 1

You could:

1) Create symlink to the images in the public folder?

2) As you are using the images publicly, they should really be in the public folder - why are they currently not?

Answer 2

You need create a Controller to send_file ( http://api.rubyonrails.org/classes/ActionController/Streaming.html#method-i-send_file ) it.

class AvatarsController

  def show
    send_file my_avatar_path, :type => 'image/jpeg', :disposition => 'inline'
  end
end

In this controller you can add all authorization you want.
