title: storing app settings on Google App Engine
body: <p>I need to store settings for my Google App Engine project. Currently I have:</p>
  
  <pre><code>class Settings(db.Model):
      rate = db.IntegerProperty(default=4)
      ...
  </code></pre>
  
  <p>And when I want to use it:</p>
  
  <pre><code>Settings.get_or_insert('settings')
  </code></pre>
  
  <p>This feels clumsy so is there a better way (without using Django)?</p>
