Ruby Build a Simple Ruby on Rails Application Building the Profile Page Scoping

Uninitialized constant written shows up when I have to go the profile page. Rails 4.2.4

I can't seem to accept that page by the user_id number or by the profile name

Profile controller

class ProfilesController < ApplicationController

  def show
    @user = User.find_by_profile_name(params[:id])
    if @user
      @statuses = @user.statuses.all
      render action: :show
      render file: 'public/404', status: 404, formats: [:html]


<div class="page-header">
  <h1><%= @user.full_name %></h1>

<% if @statuses %>
  <% @statuses.each do |status| %>
    <div class="well">
      <%= status.content %>
      <hr />
      <%= link_to time_ago_in_words(status.created_at), status_path(status) %> ago
  <% end %>
<% end %>

User model page

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

    validates :first_name, presence: true
    validates :last_name, presence: true
    validates :profile_name, presence: true, uniqueness: true

    def full_name
     full_name = "#{first_name}  #{last_name}"


Did you get this fixed?

Not quite, I have run into some new issues with it. I have started working on my own app in hope that i figure where i went wrong.

OK - cool. If you want me to have a look at the Treebook code, just link me to the Github report and I'll take a look.
