NoMethodError in Statuses#Index

Hey All,

I am trying to follow along with the videos and create a full_name method. I keep getting the error "NoMethodError in Statuses#Index" and a little under that it says "undefined method `full_name' for nil:NilClass". I have a feeling it's something really simple that I'm missing.

Code: (The method call is on the 3rd line, "status.user.full_name")

<% @statuses.each do |status| %>
  <div class="status">
    <strong><%= status.user.full_name %></strong>
    <p><%= status.content %></p>
    <div class="meta">
      <%= link_to time_ago_in_words(status.created_at) + " ago", status %>
      <span class="admin">
        | <%= link_to "Edit", edit_status_path(status) %> | 
        <%= link_to "Delete", status, method: :delete, data: {confirm: "Are you sure you want to delete this status?"} %>
      </span>
    </div>
  </div>
<% end %>

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_many :statuses

  def full_name
    first_name + " " + last_name
  end
end

I'm no expert, but could it be that you should include "full_name" under "attr_accessible" so the method is, well, accessible? I had a look in my user.rb, and that's how it looks there at least. Here's a link if you wanna compare with your own

Hope it helps :)

I'm using Rails 4 and don't have the attr_accessible gem. I have been using strong params which are included in my users controller. It's been working fine for the most part, until he created the full_name method. It looks like it's just not seeing the method, unless I'm doing something else wrong.

Oh my bad, I didn't catch that you were using 4. Have you tried deleting the existing statuses in you app to make sure you don't have any old statuses from before you implemented first_name, last_name, full_name etc.?
