NameError in Statuses#index 'Creating Friendships'

Showing /Users/Wilson/Projects/treebook/app/views/statuses/index.html.erb where line #11 raised:

undefined local variable or method `gravatar_url' for #<#<Class:0x007fcdebbed668>:0x007fcdebccfd60>

  <div class="status">
    <div class="row">
    <div class="span1">
        <%= image_tag status.user gravatar_url %>
    </div>
        <div class="span7">
           <strong><%= status.user.full_name %></strong>

Everything else is to the tee, I've even downloaded the project file to verify it's identical, but I can update this discussion if you think it might be wrong.

It should be: status.user.gravatar_url

Still getting the same error.

undefined method `gravatar_url' for nil:NilClass

It's a different error. Before it didn't recognise the gravatar_url method. Now it's saying the user object is nil. Have you set up the associations in the user class and the status class? Is the database in a consistent state, i.e. the user_id values in the statuses table exist in the users table?
