Answer 1

A simple solution is to create a new js-file ( further called activate.js ) and include the files there.

# < FolderWithFiles >/activate.js :

//= require_tree . 

Answer 2

You can use

<%= javascript_include_tag :all %>

But this will work only if the scripts are stored in your

RAILS_ROOT/public/javascripts

directory

Answer 3

According to the API documentation of javascript_include_tag:

Returns an html script tag for each of the sources provided.

You can pass in the filename (.js extension is optional) of javascript files that exist in your public/javascripts directory for inclusion into the current page or you can pass the full path relative to your document root.

You cannot recursively include all files in your directory. However, you always can write something like the next line:

javascript_include_tag *Dir[Rails.root.join("public/javascripts/views/**/*.js")]

Answer 4

The following (unoptimized) code should work in rails 3.0 or above

<%= javascript_include_tag Dir[Rails.root.join("public/javascripts/views/**/*.js")].map { |s| s.sub(Rails.root.join("public/javascripts/").to_s, "") } %>
