Rails: Bootstrap dropdown menu not working

Question

I am quite new to Rails and have been following the tutorial by Michael Hartl. Everything has been going along really well until I got to the drop down menu, which was wasn\'t

Answer 1

The problem is bootstrap's javascript. Sometimes is loaded two times.

This works to me:

application.js:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap

application.scss: Don't use //= require in scss files

@import "*";
@import "bootstrap";
@import "font-awesome";

Then:

rake assets:clean
rake assets:precompile 

OR

Put bootstrap.js in assets/javascripts folder and put //= require_tree . line
