I cannot load my main page in the treebook project with Ruby on Rails. I keep getting this error. Not sure what I am doing wrong here. 

undefined method `full_name' for nil:NilClass
Extracted source (around line #9):

6: 
7: <% @statuses.each do |status|%>
8: <div class="status">
9:  <strong><%= status.user.full_name %></strong>
10:     <p><%= status.content%></p>
11:     <div class"meta">
12:         <%= link_to time_ago_in_words(status.created_at) + " ago", status %>

I have recently taken this entire video set and ran into this as well. If you follow the video step-for-step you will run into this, and for me it was a matter of dropping the old database and starting fresh.

In the video Jim suggested deleting certain status post, then editing the remaining posts with a user, otherwise you would get a different error as well.

Took me a few days to figure out, but finally got <%= status.user.full_name %> to work.

Try starting with deleting all users, and all statuses, in rails console. In the rails console type: (user = User.all) then: (user.delete_all) then: (status = Status.all) and lastly: (status.delete_all)

Go back to the app, create a new profile and post a new status. You should see your full name displaying correctly.

You may also need to add a few devise parameter sanitizers to your Application Controller. You should be able to find those answers in the forum if necessary.

Hope this helps!
