Rails - Jan 2005 - Streaming a file to the browser

I''ve begun work on a photo gallery application.  I''ve got some
basics
working, but I''m struggling to find an easy way to stream an image
from outside the webroot to the browser.  There used to be a method
(send_file I believe) but I cannot find it in .92.  Any suggestions on
an easy way to accomplish this?

It just dropped out of the documentation. It''s still there:
http://ap.rubyonrails.org/classes/ActionController/Base.html#M000060

It''ll be back in the next release.

I created a ''render_image'' in a document controller a while
ago:
====
require ''abstract_application''
require ''document''

class DocumentController < AbstractApplicationController
	def index
		@page_title="Documents"
		@documents=Document.find_all
	end
	def create
		@document=Document.new do |d|
			d.name=@params["document"].original_filename.gsub(/[^a-zA-Z0-9.]/,
''_'')
			d.size=@params["document"].size
			d.mime=@params["document"].content_type
			d.document=@params["document"].read
		end
		@params.delete("document")
		@document.save
		redirect_to :action=>"index"
	end
	def destroy
		Document.find(@params["id"]).destroy
		redirect_to :action=>"index"
	end
	def download
		@document=Document.find(@params["id"])
		@response.headers["Pragma"]=""
		@response.headers["Cache-Control"]=""
		@response.headers["Content-type"]=@document.mime
		@response.headers["Content-Disposition"]="attachment; 
filename=#{@document.name}"
		@response.headers["Accept-Ranges"]="bytes"
		@response.headers["Content-Length"]=@document.document.length
		@response.headers["Content-Transfer-Encoding"]="binary"
		@response.headers["Content-Description"]="File Transfer"
		render_text @document.document
	end
	def render_image
		@document=Document.find(@params["id"])
		@response.headers["Content-type"]=@document.mime
		render_text @document.document
	end
end
