Flash messages when creating friendships not displaying at all.

This is my controller :

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)

      flash[:error] = "Friend Required"
  rescue ActiveRecord::RecordNotFound
    render file: 'public/404', status: :not_found

  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)
      flash[:success] = "You are now friends with #{@friend.full_name}" 

      redirect_to profile_path(@friend)
      flash[:error] = "Friend required"
      redirect_to root_path

Flash messages dont show at all, and I've no idea why, could any one help ?:)
