Rails-Admin icon broken - ruby-on-rails

Question

I'm using Rails-Admin for the dashboard of Rails app. But on dashboard, the icons are all same - white square.
Screenshot for Broken Icons:

end
Is there any mistake while using the rails admin or other gems?
Any suggestion would be helpful!

I think you need to use font-awesome gem. I had the same issue before.
Rails admin uses an old version of fontawesome. Download the zip file here: http://fortawesome.github.io/Font-Awesome/3.2.1/assets/font-awesome.zip
Then put the following files into the /public/assets directory of your rails project, from the /font directory in the zip file:
fontawesome-webfont.eot
fontawesome-webfont.svg
fontawesome-webfont.ttf
fontawesome-webfont.woff
FontAwesome.otf
