How can I print out an image tag to a Rails asset in javascript?

Question

If I have an image at /assets/images/my_image.png, the following will show an image in development, but not in a production.

$('.myImage').html('<img src="/assets/images/my_image.png">');

Nah - you can see the image asset missing here - dailydebate.co. If you click "agree" or "disagree" you should see the missing image icon. — Don P

other images in the app are working fine? whatis the value of config.serve_static_assets in prod.rb — Nithin

config.serve_static_assets = false... so that sounds like a good thing to change. Does that hurt something else? guides.rubyonrails.org/configuring.html — Don P

For heroku

  config.serve_static_assets = true

also use

gem 'rails_12factor', group: :production

heroku docs has good explanation you need to check out once.

Hmm, this still doesn't seem to solve it. I'll move it into /public for now

config.assets.compile = true is set? which version of rails?

I see the image in your app now :)
