Delete link for user isn't showing up - html

Question

I am new to web development (I have been coding for about 6/7 months now) in hopes of building my own app. I have been reading and working of the Ruby on Rails tutorial by Michael Hartl. I am on the chapter 9 section deleting users and am stuck. Everything works for the most part except that the user link. It just doesn't show on the display page. The users and their avatars fine. I just can't figure out a way to get the user delete link to show. Below is the code for the user model, the user controller, the session controller where the code current user lives and the view.
Also, when ever i take out the if statement from the user partial the delete link shows. I am not sure whats wrong since I already defined admin, and the current_user.
I would be entirely grateful for any kind of guidance. My project is also on github if the information below isn't sufficient enough

class UsersController < ApplicationController
before_action :logged_in_user, only: [:index, :edit, :update, :destroy]
before_action :correct_user, only: [:edit, :update]
before_action :admin_user, only: :destroy
def new
#user = User.new
end
def show
#user = User.find(params[:id])
end
def create
#user = User.new(user_params)
if #user.save
log_in #user
flash[:success] = "Welcome to the Sample App!"
redirect_to #user
else
render 'new'
end
end
def edit
#user = User.find(params[:id])
end
def update
#user = User.find(params[:id])
if #user.update_attributes(user_params)
flash[:success] = "Profile Updated"
redirect_to #user
else
render 'edit'
end
end
def index
#users = User.paginate(page: params[:page])
end
def destroy
User.find(params[:id]).destroy
flash[:success] = "Your profile was deleted"
redirect_to users_url
end
private
def user_params
params.require(:user).permit(:username, :email, :password,
:password_confirmation, :user_about_me,
:birthday, :avatar, :gender)
end

end
end
# Confirms the correct user.
def correct_user
#user = User.find(params[:id])

end
# Confirms an admin user.

redirect_to(root_url) unless current_user.admin?
end
end
.
class User < ActiveRecord::Base

# this before_save is a callback method. What it does is before it saves the email
#address it calls back and transforms all the letters into lower case. Had to do the indexing
#in active record in order for the method to work
validates :username , presence: true, length: {maximum: 250}
VALID_EMAIL_REGEX = /\A[\w+\-.]+#[a-z\d\-.]+\.[a-z]+\z/i
#code that ensures that a user puts the right format for emails in signup

#whether the user types CAMELcase or lowercase
validates :password, presence: true, length:{maximum: 50}, allow_nil: true
validates :user_about_me, presence: true
validates :birthday, presence:true
has_secure_password
# Returns the hash digest of the given string.
def User.digest(string)
cost = ActiveModel::SecurePassword.min_cost ? BCrypt::Engine::MIN_COST :
BCrypt::Engine.cost
BCrypt::Password.create(string, cost: cost)
end
## returns a random user token
def User.new_token
SecureRandom.urlsafe_base64
end
# Remember a given user to the database for use of persistent sessions
def remember
self.remember_token = User.new_token
update_attribute(:remember_digest, User.digest(remember_token))
end
##returns true if given token matches the digest
def authenticated?(remember_token)
return false if remember_digest.nil?
BCrypt::Password.new(remember_digest).is_password?(remember_token)
end
def forget
update_attribute(:remember_digest, nil)
end
def log_out
forget(current_user)
session.delete(:user_id)
#current_user = nil
end
end
This is the code in the partial rendering on the index page where all users show up.
<div class="col-md-9 col-offset-3" id="index-profile">
<li class="users">
<div class="col-xs-3 profilepic-container">
<%= image_tag user.avatar.url %>
</div>
<%= link_to user.username, user %>
<% if current_user.admin? && !current_user?(user) %>
| <%= link_to "delete", user, method: :delete,
data: { confirm: "You sure?" } %>
<% end %>
</li>

Answer 1

The delete link in your partial has two conditions that are required to be true. The user must be an admin, and the profile must not be their own profile. So if the admin user is the only user, then no delete link will show up.
Try creating a second user and see if the delete link shows up for that user.
