gem jquery-ui-rails couldn't find file 'jquery.ui.all' (
At version 5.0 it has been changed. You can read more about it here.
version 5.0:
application.js:
//= require jquery-uiapplication.css:
/* *= require jquery-ui */version 4.x (I'm sure about 4.2.0 and 4.2.1):
application.js:
//= require jquery.ui.allapplication.css:
/* *= require jquery.ui.all */
Put //= require jquery.ui.all right after //= require jquery so it will look like this
//= require jquery//= require jquery.ui.all//= require jquery_ujs//= require underscore//= require backbone//= require svitla_test//= require_tree ../templates//= require_tree ./models//= require_tree ./collections//= require_tree ./views//= require_tree ./routers//= require_tree .note that the order of which these lines are written is the order which these files are loaded.. So if you call a jquery-ui function before it knows what jquery-ui is, most likely you need to change the order a bit..
It is usually good to put infrastructure files before your own files to avoid these kind of problems
