class User < ActiveRecord::Base
  # Paperclip
  @current_user.has_attached_file :photo,
     :styles => {
       :thumb=> "100x100#",
       :small  => "150x150>",
       :medium => "300x300>",
       :large =>   "400x400>" }


This is the method for where the user uploads the photo: 

 def photoUpload
    
    @user = @current_user
  
  end

And this is the view for uploading that photo: 

<%= error_messages_for :photo %>

<% form_for(@user,:html => { :multipart => true }) do |f| %>
<%= f.error_messages %>
 <p>
    <%= f.label 'Photo' %><br />
    <%= f.file_field :photo %>
  </p>
  <p>
    <%= submit_tag 'Upload' %>
  </p>
<% end -%>
