Friendship request button not showing on page...

For whatever reason all my links work except when I click "Add Friend" on my profile page it directs me to the correct path, however on this page my menu shows but no Ruby code shows...

So I believe Im getting redirected correctly but I feel something is wrong with my controller or Ruby code on new.html.erb... I have tried different things but cant finger this one out..

any Ideas?

Thanks, Daniel

user_friendships_controller.rb

def new
  if params[:friend_id]
    @friend = User.find(params[:id])
    @user_friendship = current_user.user_friendships.new(friend: @friend)
else
    flash[:error] = "Friend required"
end
   rescue ActiveRecord::RecordNotFound
   render file: 'public/404', status: :not_found
 end

user_friendships/new.html.erb

<% if @friend %>
    <h1><%= @friend.Biz_name %></h1>
    <p>Do you really want to friend <%= @friend.Biz_name %>?</p>

 <%= form_for @user_friendship, method: :post do |form| %>
  <div class="form form-actions">
    <%= form.hidden_field :friend_id, value: @friend.id %>
    <%= submit_tag "Yes, Add Friend", class: 'btn btn-primary' %>
    <%= link_to "Cancel", user_path(@friend), class: 'btn' %>
  </div>
<% end %>
<% end %>

Not sure what this "@friend.biz_name" is. I'm assuming you modified the code a bit from the course?

Here's what my files look like.

user_friendships_controller.rb

class UserFriendshipsController < ApplicationController
before_filter :authenticate_user!, only: [:new]

def new
    if params[:friend_id]
        @friend = User.where(profile_name: params[:friend_id]).first
        raise ActiveRecord::RecordNotFound if @friend.nil?
        @user_friendship = current_user.user_friendships.new(friend: @friend)
    else
        flash[:error] = "Friend Required"
    end

rescue ActiveRecord::RecordNotFound
    render file: 'public/404', status: :not_found
end

def create
    if params[:user_friendship] && params[:user_friendship].has_key?(:friend_id)
    @friend = User.where(profile_name: params[:user_friendship][:friend_id]).first
    @user_friendship = current_user.user_friendships.new(friend: @friend)
    @user_friendship.save
    flash[:success] = "You are now friends with #{@friend.full_name}"
    redirect_to profile_path(@friend)
    else
        flash[:error] = "Friend required"
        redirect_to root_path
    end
end
end

user_friendships/new.html.erb

<% if @friend %>
<h1><%= @friend.full_name %></h1>

<p>Do you really want to friend <%= @friend.full_name %>?</p>

<%= form_for @user_friendship, method: :post do |form| %>
    <div class="form form-actions">
        <%= form.hidden_field :friend_id, value: @friend.profile_name %>
        <%= submit_tag "Yes, Add Friend",  class: "btn btn-primary" %>
        <%= link_to "Cancel", profile_path(@friend), class: "btn" %>
    </div>
<% end %>
<% end %>

Hey Moiz thanks for the reply! Yeah I renamed some things and have some differnt Paths but all in all everything is the same... For example my full_name = Biz_name... And my profile_path is user_path..

For whatever reason my /new.html.erb page renders my application file aka my menu however my ruby code will not show on the page. I feel like for some reason I need something different in this line of code <% if @friend %>. I'v tried different things but nothing seems to work.. Everything in my application works except this one page..

Also the same thing happens in Heroku.... Below are my heroku logs ... Normally I can figure out an error from the logs but can't get this one..
