[Rails] Ruby code on Chef as a "ruby_block" not working

Hi Ruby hackers,

I have very limited knowledge of the Ruby programming language, however, I need to implement on Chef (check-solo) something similar to "augeas" (which works with Puppet, but here I need a solution for Chef).

I got the example code below but it's not working and I am now for a few days trying to figure out what is wrong.

Basically I need to be able to select specific strings in a text file and modify these values. I could use sed but perhaps I can do it in a more elegant way using the ruby_block from Chef.

Please let me know what can be possibly wrong with the code below. Why is my /etc/hosts not being updated with new values?

Always when I re-run chef-solo, I get the following error:

NoMethodError
-------------
undefined method `chef' for Chef::Resource::RubyBlock


Thanks for your help.

Follows my default.rb file:

Code:

ruby_block "edit etc hosts" do    block do      rc = Chef::Util::FileEdit.new("/etc/hosts")      rc.search_file_replace_line(        /^127\.0\.0\.1 localhost$/,        "127.0.0.1 #{new_fqdn} #{new_hostname} localhost"      )      rc.write_file    end  end
