friendly_id gem for current_user

Question

I've been trying to figure out how to use the current_user user_name as their url. Currently it looks like http://localhost:3000/users/2 instead of http://localhost:3000/users/user_name. All help is appreciated. For any questions, please ask.

User.rb

class User < ActiveRecord::Base
 extend FriendlyId
 friendly_id :user_name, use: :slugged

User Controller changed all @user = User.friendly.find(params[:id) as shown below. Not the entire listing but you can see what I mean.

class UsersController < ApplicationController
  def index
   @user = User.new
   if @current_user
    @leaders = @current_user.leaders
   end
  end

  def create
   @user = User.new(user_params)
   if @user.save
    session[:user_id] = @user.id
    cookies[:user_id] = @user.id
    flash[:notice] = "Welcome"
    redirect_to "/users/#{ @user.id }"
   else
    flash[:alert] = @user.errors.full_messages
    redirect_to "/users/new"
   end
  end

  def new
   @user = User.new
  end

  def edit
   @user = User.friendly.find(params[:id])
   current_user
  end

  def show
   @user = User.friendly.find(params[:id])
   if current_user
    @followerlink = DateRate.where(leader_id: @user.id,
                                 follow_id: current_user.id).first
    @reverselink = DateRate.where(leader_id: current_user.id,
                                follow_id: @user.id).first
   end
  end

  def update
   @user = User.friendly.find(params[:id])
   if @user.update(user_params)
    flash[:notice] = "Updated profile"
    redirect_to "/users/#{ @user.id }"
   else
    flash[:alert] = @user.errors.full_message
   end
   redirect_to "/users/#{ @user.id }/edit"
  end

Schema

create_table "users", force: true do |t|
   t.string   "user_name"
   t.string   "email"
   t.string   "password_digest"
   t.text     "about_me"
   t.string   "slug"
end

add_index "users", ["slug"], name: "index_users_on_slug", unique: true

If I should add more files in order to have a better understanding, please let me know. Thank you for any help given.

Normally, It should work with

user_path(current_user)

But more specifically, try this,

user_path(current_user.to_param)
