4,824 PointsFriendship 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 %>

11,906 PointsNot 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 %>

4,824 PointsHey 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..
