Ruby Build a Todo List Application with Rails 4 Build a Todo List Application with Rails 4 Generate a Scaffold

NoMethodError when generating scaffold with Rails 4.1.4.

I was following 'Generate a Scaffold' under 'Build a Todo List Application with Rails' and I have Ruby 2.1.2. and Rails 4.1.4. installed on my Mac. I have followed every step as shown in the video until typing 'bin/rails generate scaffold todo_list title:string description:text' in the console. When I do so I get the following error after 'spec/controllers/todos_controller_spec.rb' is created;

(erb):82:in template': undefined methodupdate_attributes' for #<Rails::Generators::ActiveModel:0x007fe79e5bc038> (NoMethodError)

I believe this is something to do with earlier version of Ruby and Rails used for this tutorial. Could someone please help me solve this issue? Many thanks.

I'm not sure if this matters as much but in the video it shows that name of the file should be

'spec/controllers/todo_lists_controller_spec.rb' but you have 'spec/controllers/todos_controller_spec.rb', which means you are missing the word lists in the file name. Good luck!

I have the right name of the file, but the same problem... Please help if someone figured out what's the problem?
