Subject: Rails list method

I have setup rails and it works nicely. I have used the scaffolding to 
get started(brilliant) but when I get to replacing the list method, I 
get an error. I have gone through the tutorials thoroughly but I cannot 
find anything wrong. It could be something simple as I do not know much 
about rails. The error I get is the following:

  NoMethodError in  Friends#list

  Showing /friends/list.rhtml where line #10 raised  undefined method 
`each' for nil:NilClass
7: <h1>Friends#list</h1>
8: <p>
9: <b>Names of all the people</b>
10: <% @people.each do |@item| %>
11: Name: <%= person.name %><br/>
12: <% end %>
13: <%=link_to "List",  :action => "list" %>


Show template trace

Request

Parameters: None

Show session dump

Response
Headers: {"cookie"=>[],  "Cache-Control"=>"no-cache"}

Show template parameters


The code is:

   def list
     @person = Person.find_all
   end

And the view is:

<b>Names of all the people</b>
<% @people.each do |@item| %>
Name: <%= person.name %><br/>
<% end %>


I have tried several styles of code. Using for instead of each in the 
view;Using the list method from the scaffolding straight. But every 
time I get this response. The data in the MySQL database is pretty 
simple. What am I doing wrong? When I saw the nilClass I thought that 
person was not being correctly passed on but because my knowledge of 
rails is minimal, I'm pretty much stuck.

I would appreciate any help or comments.
