title: rails 4.0, rake db:sessions:create
body: <p>Rails 3.1 suggests running </p>
  
  <pre><code>rails generate session_migration
  </code></pre>
  
  <p>However this generates the exact same migration as </p>
  
  <pre><code>rake db:sessions:create
  </code></pre>
  
  <p>but none of the commands are recognized by my setup using rails 4.0</p>
  
  <p>errors are :</p>
  
  <blockquote>
    <p>Could not find generator session_migration.</p>
  </blockquote>
  
  <p>and </p>
  
  <blockquote>
    <p>Don't know how to build task 'db:sessions:create'</p>
  </blockquote>
  
  <p>respectively.</p>
  
  <p>I have run:</p>
  
  <blockquote>
    <p>gem install 'activerecord-session_store'</p>
  </blockquote>
  
  <p>How do I make it work so that i can store a shopping cart bigger than 4kb?</p>
