Rails 4：application.js中的“ // = require_tree”在/ app / assets / javascripts中不包含我的js文件

Question

I'm trying to follow a tutorial on adding d3.js graph to Rails 4 application. The example application is on github and works as expected.

My problem is that when I try to replicate this application from scratch or add this graph to my existing project the js file in /app/assets/javascripts is not included in resources for some reason despite the fact that the //= require_tree . line is present in /app/assets/javascripts/applications.js files.

I can see this as the only problem since if I paste the code from problematic file into the console, it works.

I found similar questions and followed advice given but couldn't fix my problem.

I've already tried rake assets:precompile suggested here

Can anybody help?

I had the same problem. I had file.coffee and I created file.js which was not added. When I renamed file.coffee to file.js everything was fine. However, you could just use www.js2.coffee to convert your js code to coffee and then use the file.coffee file instead.
