Generating the User Model: "undefined method 'each'

After installing devise, I'm able to go to localhost:3000/users/sign_up and create a new user, no problem. Yay! but, my status/index page now won't load. This is the error message I'm getting: 

      Showing C:/Sites/Treebook/app/views/statuses/index.html.erb where line #7 raised:

undefined method `each' for nil:NilClass

Extracted source (around line #7):

4: 
5:  <%= link_to "Post a New Status", new_status_path, class:"btn btn-statuses" %>
6: 
7:  <% @success.each do |status| %>
8: <div class="status hover">
9:      <strong><%= status.name %></strong>
10:         <p><%= status.content %></p>

any ideas what to do?

It looks like @success is nil. Should it be a different variable, like @statuses?

Alan -

that was it. thanks!

to recap for posterity:

You must match the variable in your views/statuses/index.html.erb to the status controller file in order to avoid getting the Nil Class error.
