Rails - Jul 2006 - send_data image

I''m trying to display an image in a view from MySQL, but I''m
not sure
where to put the send_data call.

Any help would be great. :)

Make a controller that calls send_data when sent the relevant object :id
as a parameter, and make it the image src ...

def show_image
	o=Object.find(params[:id])
	send_data o.jpg, :type=>"image/jpeg",
:disposition=>''inline''
end

If your Object can store different types of image, don''t call them
o.jpg
:-) and make sure you can intuit the correct MIME type ... perhaps by
storing that in the object as well ...
	send_data o.img, :type=>o.mimetype,
:disposition=>''inline''

Then invoke the show_image controller as the src of an image tag,
sending the Object.id as a parameter ...

<img src="show_image/1" />

(You should be able to assemble the correct URL with link_to calls)
