No Method Error - Undefined method 'chomp'

Question

I am very new to Ruby on Rails and currently running through the Michael Hartl tutorial.I've started to get a crazy long error when trying to call any method. Doesn't matter which. The one below is from running:

rails generate controller StaticPages about --no-test-framework

And then I get the following error:

/Users/MYUSERNAME/rails_projects/sample_app/config/initializers/secret_token.rb:18:in `secure_token': undefined method `chomp' for #<Pathname:/Users/MYUSERNAME/rails_projects/sample_app/.secret> (NoMethodError)

My assumption is that is as something to do with my RVM and the gems that I have. I know its a very long error and lot of it is unique to the project that I am working on but any help is greatly appreciated. Keep in mind that I'm serious noob!

Edit:

require 'securerandom'

def secure_token
token_file = Rails.root.join('.secret')
if File.exist? (token_file)
    #Use the existing token
    File.read token (token_file).chomp
else
    #Generate a new token and store it in token_file.
    token = SecureRandom.hex(64)
    File.write(token_file, token)
    token
end
end

SampleApp::Application.config.secret_key_base = secure_token

Answer 1

Replace chomp with to_s:

File.read token (token_file).to_s
