New for Rails / paper clips - paper clips will not save

Question

I am very new to programming and I am trying to use paperclip to add a user photo to my user posts. Records can be created from the new recording form without the string <% = f.file_field: photo%> and redirected correctly and saves the record in the database. However, when it is included in save, it wants to redirect to create.html.erb instead of the user path and does not save the new record. It also does not display any errors. I updated the users table with the fields photo_file_name, photo_content_type and: photo_file_size. In addition, I run windows if this is any help.

Model:

class User < ActiveRecord::Base
  has_many :venues
  has_many :reviews
  has_attached_file :photo,
    :styles => { 
      :medium => "300x300>", 
      :thumb => "100x100>" }
end

Controller:

class UsersController < ApplicationController

  def index
    @users = User.all
  end

  def new
    @user = User.new
  end

  def create
    @user = User.create(params[:user])
    if @user.save
      flash[:notice] = 'User added'
      redirect_to users_path
    else
      @user.save
    end
  end

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

View:

<% form_for (@user, :html => { :multipart => true }) do |f| %>

  <p>username: <br>
  <%= f.text_field :username %></p>

  <p>password: <br>
  <%= f.text_field :password %></p>

  <p>photo: <br>
  <%= f.file_field :photo %></p>

  <%= submit_tag %>
<% end %>

Any help is much appreciated!

What is shown in the development log:
