Permission denied on deploying Rails

Hi, I have successful deployed my Rails app on Ubuntu 14 but as I used active_admin gem so I got the below error with the stylesheet:

I, [2014-10-27T10:25:29.983751 #4242]  INFO -- :   Rendered vendor/bundle/ruby/2.1.0/bundler/gems/activeadmin-0173d95712a8/app/views/active_admin/devise/shared/_links.erb (2.0ms)

    10:   <% end %>
    11:   <% ActiveAdmin.application.javascripts.each do |path| %>
    12:     <%= javascript_include_tag path %>

Not sure what permission should I have here? Could you please assist me with this? Cheers, Leo

A fix that worked for me was to clear the cache

rake tmp:cache:clear

Your app server can’t write the tmp directory of your application.

One solution would be making the group of the tmp folder the user that is running the app server and giving write permission to the group.

# Replace server with the name of the user running the app server.
chgrp -R server /home/rails/tmp
chmod -R g+w /home/rails/tmp

@kingsleychi: Cheers, mate. That actually worked. Sorry for my super late response. All good now ;-)
