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

    <%= @status.user.full_name %>

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


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

# 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!

Could you run the following command in your shell/command prompt and post the results

     rails -v

Rails 4.0.4

Lachlan Dawson as I suspected. The version of Rails in the videos is 3.2. The attr_accessible has been changed to strong parameters in the latest version. Also numerous other things have changed. If you don't have a great grasp of Rails you would be best to start over with the correct version of Rails. Otherwise it will cause you no end of trouble.

Hope this helps
