Why is test not passing and what do i need to do to fix?

1) Creating todo lists redirects to the todo list index page on success
        Failure/Error: expect (page) .to have_content ("New todo_list")
        NoMethodError :
            undefined method 'to' for #<Capybara :: Session>
        # ./spec/features/todo_lists/create_spec.rb:7:in  'block  (2 levels) in <top (required)>'

Deprecation Warnings:

-----------------------------------------------------------------------------------------------------------------
RSpec::Core::ExampleGroup#example is deprecated and will be removed
in RSpec 3 There are a few options for what you can use instead:

    - rspec-core's DSL methods ('it', 'before', 'after', 'let', 'subject' , etc)
        now yield the example as a block argument, and that is the recommended
        way to access the current example from those contexts.
    - The current example is now exposed via  'RSpec.current_example',
      which is accessible from any context.
    - If you cant update the code at this call site (e.g. because it is in
        an extension gem), you can use this snippet to continue making this 
        method available in RSpec 2.99 and RSpec 3:

                RSpec.configure do |c|
                        c.expose_current_running_example_as :example
                end
