Getting this error message NoMethodError in Statuses#show

Hi, I keep getting this error message when trying to get my project to show the full names.

undefined method `full_name' for nil:NilClass

<p>
    <strong>Name:</strong>
    <%= @status.user.full_name %>
</p>

this is how i'm calling for my full name

<%= @status.user.full_name %> and on the index page <%= status.user.full_name %>

I have included all of these snippets of code into my project as well

status.rb

class Status < ActiveRecord::Base attr_accessible :content, :user_id belongs_to :user end

user.rb

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

# Setup accessible (or protected) attributes for your model attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name, :last_name, :profile_name # attr_accessible :title, :body

has_many :statuses

def full_name first_name + " " + last_name end end

I've tried using rake db:reset and rake db:migrate but nothing seems to solve the error problem. Thank you for your help!
