ruby - What is correct path in .js file in Rails? -

-

i have js script plays video on home page , can't correct path video folder in script. works in html static project.

assets/javascript/common.js

var videobackground = new $.backgroundvideo($('#background-video'), {    "path": "/video/"  });

assets/javascript/video/ - videos in folder

i tried sending root_path variable in application file, doesn't work either.

application.html.haml

:javascript    var root_url = '#{rails.root}';

application.html.haml

var videobackground = new $.backgroundvideo($('#background-video'), {    "path": root_url + "/app/assets/javascripts/video/"  });

i not sure, if want assets, try putting video in app/assets/videos , in config/application.rb 

config.assets.paths << "#{rails.root}/app/assets/videos" config.assets.enabled = true

else put in public/videos then, video_tag "video.mp4" should automatically loaf there
