It is needed so that links that have remote: true and is not a get 
request will include the authenticity token when you click it. Search 
for jquery_ujs

What gem provides jquery-ui?  It may already be loading ujs. You can 
look at this gem of you want to use jquery ui
https://github.com/joliss/jquery-ui-rails

If you're having the error above, other js wont probably run.

In this case, I'm not sure what's wrong.  when you say app.js, do you 
mean
application.js? Or do
you have another js file by the name of app.js?

I'm also not sure about this one.  Newly generated projects dont use the
:default directive (do you call it a directive?).
They use 'application' which is the reason why I told you to change it 
to
'application' because it is trying to load default.js

error

And there is no error in dummy project.

NetworkError: 404 Not Found  - 
http://localhost:3000/assets/**defaults.js 
<http://localhost:3000/assets/defaults.js>"
