The js code is included 2 times in application.js and in its file (?

Question

Ruby on Rails

app
..assets
....javascripts
......application.js
......somecode.js
app/assets/javascripts/application.js /app/views/layouts/application.html.haml in output in public/assets I expect application.js, but I get application.js and somecode.js. And in the page code I see:
//=require somecode

= javascript_include_tag 'application'

<script src="/assets/somecode-3b9fe45f9d9a8007fa4c213cfbced5fd.js?body=1"></script>
<script src="/assets/application-3b9fe45f9d9a8007fa4c213cfbced5fd.js?body=1"></script>

Those. code connected 2 times. This unexpected behavior is annoying.
The task is this: in the javascripts folder of raw assets, collect all the necessary scripts. Include them in one application.js and collect them into one file as the output of resource compilation.

Answer 1

In addition to vsuhachev , replace
/config/environments/development.rb with If you want to have what you want in the development environment :) PS not necessarily if the file is located in and there is a line in application.js
//=require somecode/app/assets//= require_tree .

Answer 2

firstly, it matters what environment you are in, in development this behavior is normal, and assets for production are collected using the assets:precompile task;
secondly, by default, the manifest (application.js) usually has a require_tree command that includes all files from subdirectories, those. require somecode is not needed,
