Define route for return votes assoc with current user
user
```ruby
class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      session[:user_id] = @user.id
      redirect_to root_path
    else
      flash[:notice] = "ERROR"
      render :new
    end
  end

  def index
    @users = User.all
  end

  def show
    @user = User.find(params[:id])
  end

    if session[:user_id].nil?
      render json: false
    else
      @name = User.find(session[:user_id]).name
      render json: {name: @name }
    end
  end

  def current_votes
    if session[:user_id].nil?
