jquery-datatables-rails sort arrows not showing up in development environment

Question

I have a new rails install. I followed the instructions on this page exactly: https://github.com/rweng/jquery-datatables-rails

When I try to view a datatable, I get these errors:

GET http://localhost:3000/images/sort_both.png 404 (Not Found)
GET http://localhost:3000/images/sort_asc.png 404 (Not Found)

In config/environments/development.rb I've tried changing the following settings:

config.assets.debug = false #and also tried true
config.serve_static_assets = true #and also tried false
config.assets.enabled = true

I've also tried running rake assets:precompile

Not sure what I'm missing here. Any help would be greatly appreciated.

Solution

Perhaps someone will present a better answer. This is how I fixed it.

I got rid of the gem. Downloaded the javascript and css files from the datatables website:

• jquery.dataTables.min.css
• jquery.dataTables.min.js

Put these files in vendor/assets/stylesheets and vendor/assets/javascripts respectively.

I downloaded the missing images from here and stuck them in my vendor/assets/images folder that I created.

I did a replace all on the text in jquery.dataTables.min.css and replaced "/images/" with "/assets/"

And that fixed it. Hope this helps someone.
