Code Comments

missing-csrf.rb

• [High]CSRF protection must be implemented before any non-idempotent operation
  To prevent CSRF attacks, Rails provides the protect_from_forgery method to protect non-idempotent operations. Non-idempotent operations are operations that can create, modify, or delete a resource. The use of CSRF protection should be mandatory for such operations. Add the 'protect_from_forgery' method with the ':with' parameter set to ':exception' or prepend: true, with: :exception' before any non-idempotent operation.
• [Low]Unused code should be removed
  Unused code should be removed so as not to create clutter or confusion. It is easy to miss or forget about unused code, which can make code maintenance more difficult. Remove the 'puts "do more stuff"' statement or any other unused code.
