I am new to rails and web development, although I have almost two decades of C/C++ in control systems and firmware, and quite a lot of shell and perl scripting.
I can't get jquery to work without explicitly including it, even though it is in the application.js manifest, and I can't get any of the individual coffeescripts to work at all.

I wasn't getting any of the expected behavior, so in my "people" index view I added:
... <script> $(document).ready(function(){ alert("jQuery is running!"); }); </script> ... To check and see if jQuery was working at all. If I add <%= javascript_include_tag 'jquery.js' %> before the csrf_meta_tag, I get the alert message but coffeescript and the rest still don't work. Without the explicit jquery include, I get nothing.
I've looked at many, many posts on this, but none of them have worked. It appears to me that the manifest in application.js is not being read and/or the modules listed are not included, except that turbolink appears to work properly gauging by the network panel on the browser when moving from page to page. I removed turbolink and it behaves very differently.
I also tried including the jquery-turbolinks gem, although even though I'm pretty sure it's not needed with the jquery-rails gem. But it doesn't work with turbolinks uninstalled, either, so I don't think that is the conflict.
Thanks for looking.
