@Bernard can you share how you solved the issue? It might be helpful to others if they come across the same problem.

Amit...am not particularly sure how i got around this issue, i cleaned a couple of erroneous syntax and ran rake db:test:prepare.... wish i could be more helpful

The reason that running rake db:test:prepare worked is that it cleared out some information from the test database. The test database may have had an error and had some stale data in it. By clearing it, the offending data was removed.

I am getting a similar problem,

#index when logged in should get the index page without error. (UserFriendshipsControllerTest): ActionView::Template::Error: undefined method 'each' for nil:NilClass
21 tests, 26 assertions, 0 failures, 3 errors, 0 skips

I tried rake:db:test:prepare, but still get the same message. I suspect the problem is with my index.html.erb

<div class="page-header">
    <h1>Friends</h1>
</div>

<% @user_friendships.each do |friendship| %>
<% friend = friendship.friend %>
<div id="<%= dom_id(friendship) %>" class="friend row">
    <div class="span1">
        <%= link_to image_tag(friend.gravatar_url), profile_path(friend) %>
    </div>
    <div class="span7">
        <strong><%= friend.full_name %></strong><br />
        <% if friendship.pending? %>
        <em>Friendship is pending.</em> <%= link_to "Delete request", edit_user_friendship_path(friendship) %>.
        <% end %>
        <% if friendship.requested? %>
        <em>Friendship requested.</em> <%= link_to "Accept friendship", edit_user_friendship_path(friendship) %>. 
        <% end %>
        <% if friendship.accepted? %>
        <em>Friendship started <%= friendship.updated_at %>.</em> <%= link_to "Update friendship", edit_user_friendship_path(friendship) %>.
        <% end %>
    </div>
</div>
<% end %>

I can't seem to figure out why my friend = friendship.friend code in my index is turning up nil. Can't pass the user_friendships_controller test.

1) Error: test: #index when logged in should assign user_friendships. (UserFriendshipsControllerTest): ActionView::Template::Error: undefined methodgravatar_url' for nil:NilClass /Users/iMac/Documents/DougCode/treebook/app/views/user_friendships/index.html.erb:17:in block in _app_views_user_friendships_index_html_erb__3894510645546886624_70265993576780'

Index.html.erb <% @user_friendships.each do |friendship| %> <% friend = friendship.friend %> <div id="<%= dom_id(friendship) %>" class="friend row"> <div class="span1"> <%= link_to image_tag(friend.gravatar_url), profile_path(friend) %> </div>

Hey Doug Wright can you zip up your code and email it to help@teamtreehouse.com and I'll take a look?

Hi Jason,

Well, I avoided the failing test by adding a conditional: https://github.com/mrdougwright/treebook/commit/3357ebfac000ea81bcba6cee16f3457b3ec7156c

Now that I've finished the course, I've removed that conditional and everything passes. So I'm not quite sure what fixed it!

Best, Doug
