Rails - How to send an image from a controller

Question

in my rails app, I need to pass back a image.

I have a 1x1.gif tracking pixel in my route as follows:

 match \"/_ctrack.gif\" => \"email_tracking_         


        

Answer 1

Wouldn't be better to use send_file instead?

send_file Rails.root.join("public", "file.gif"), type: "image/gif", disposition: "inline"
