Clarifications for online wiki TutorialHelperMethods page?

hello,

i’m confused with the instructions on this page:

http://wiki.rubyonrails.org/rails/pages/TutorialHelperMethods

at the top of this page in red, it reads:

'Error in previous page: The show.rhtml does not exist. In previous
versions of the Scaffolding tutorial it tells you to change the name
of the view.rhtml file to show.rhtml and to change the controller
accordingly, but with a parameter, like this:

def show
@person=Person.find(@params[“id”])
end

And create show.rhtml as a copy of view.rhtml’

first it says above, ‘change the name of the view.rhtml file to
show.rhtml…’
and then it later says above, ‘and create show.rhml as a copy of
view.rhtml’.

but this is confusing.

  1. in my app/views/friends/, i see a ‘view.rhtml’ file.
  2. i change the name of this file from view.rhtml to show.rhtml. done.
  3. i edit the app/controllers/friends_controller.rb replacing ‘view’
    with ‘show’ and replacing the Person.find parameter information.
  4. then it says ‘create show.rhtml as a copy of view.rhtml’ – but i
    just moved view.rhtml to show.rhtml in #1, so show.rhtml already
    exists, and view.rhtml no longer exists!

could someone please clarify this for me and/or on that web page as
well?

furthermore,
at the end of these instructions, could someone clarify the following:
-that view.rhtml no longer exists?
-that show.rhtml exists, with the following in it:

Friends#view

this page will display one friend

<%= @person.name %>
<%= @person.street1 %>
<%= @person.street2 %>
<%= @person.city %>
<%= @person.state %>
<%= @person.zip %>

<%= for phone in @person.phones %>
<%= phone.phone %>

<%= end %>

List
Delete

-that a separate (from the ‘def show’ method) ‘def view’ method no
longer exists in the friends_controller.rb file?

thanks in advance for any clarifications.
