can't convert Fixnum into String to_param

I was getting this error in to_param method. I had to explicity call to_s on id to fix it. My to_param method :

def to_param
name_slug ? "#{id.to_s}-#{name_slug.parameterize}" : id.to_s
end

If the name slug is not nil then it uses that to generate the SEO friendly URL otherwise it uses the id.

Hivelogic instructions for ruby path

If which ruby shows /usr/bin/ruby instead of /usr/local/bin/ruby , it means you have not set the PATH correctly. I had to add a line: source ~/.profile to the ~/.bash_profile file. Now whenever you bring up the terminal and when you check the PATH, usr/local/bin will come before /usr/bin and the latest installed version will be picked up (which ruby will output /usr/local/bin/ruby)
