Javascript features work on localhost but not when deployed to Heroku

Question

I\'ve noticed that when I deploy to Heroku, javascript features dont work (such as Bootstrap Popover, Buttons, etc). I\'m working with rails 3.2.2, ruby 1.9.3. The features

Answer 1

I also had similar problem but the problem was happening on localhost as well.

You are probably using rails-bootstrap gem. It installs a file bootstrap.coffee.js This file was culprit. It had .popover use and relevant plugin was not included. I commented that out as I was not using it anyway but you should consider including the popover plugin for bootstrap.

Answer 2

I had the exact same issue (I'm very new to Rails). I eventually solved the issue by rearranging the order of files within application.js:

//= require jquery
//= require jquery_ujs
//= require twitter/bootstrap

For the javascripts to work in development, "require jquery" needed to be after "require twitter/bootstrap." In production, jquery needed to come first. Not sure what caused this, but it now works when deployed to Heroku.

I used these two posts:

javascript - Twitter bootstrap jquery plugins not compiled for production

twitter bootstrap drop down suddenly not working

Answer 3

Updating sprockets worked for me: bundle update sprockets

Answer 4

Checked the minified js for my app, and popover was twice in the file.

Be sure that only one of bootstrap and boostrap-sprockets is declared in your javascript assets

From the docs:

bootstrap-sprockets and bootstrap should not both be included in application.js.

bootstrap-sprockets provides individual Bootstrap Javascript files (alert.js or dropdown.js, for example), while bootstrap provides a concatenated file containing all Bootstrap Javascripts.

Be sure that only one of bootstrap and bootstrap sprockets

Answer 5

If you've already tried heroku run rake assets:precompile and the JS still isn't working, try doing heroku restart to restart the server after precompiling assets.

Answer 6

Manually precompiling worked for me.

bundle exec rake assets:precompile before you push to heroku.
