Great!!
when user_id is null (and can be null in some cases)
you can do this
<%post.each do |p|%>
<%=p.user.name unless p.user.nil?%>
<%end>
other way is
<%=p.user.name unless p.user.empty?%>
Or, you can push that into the model and avoid the extra logic in the
view:
class Post
def user_name
self.user ? self.user.name : "(none)"
end
end
<% @posts.each do |post| %>
<%= post.user_name %>
<% end %>
You could name the method something like "author_string" or "by_line",
too. The idea is to keep the view very clean. You might be able to
simply `delegate :name, :to => :user` in your Post model, but that
would have given you the same problem if the post.user_id referred to
a non-existent User.

For posterity that should be user.rb not User.rb of course
