title: Google appengine, ndb, and Json
body: <p>I have an attribute that I'm storing as a JSON object, like so:</p>
  
  <pre><code>content  = ndb.JsonProperty()
  </code></pre>
  
  <p>When I do this, I get this error:</p>
  
  <pre><code>   line 1614, in _to_base_type
      return json.dumps(value, 2)
  AttributeError: 'module' object has no attribute 'dumps'
  </code></pre>
  
  <p>inside the ndb model class.</p>
  
  <p>As a <code>ndb.TextProperty</code> it works properly.  Maybe I'm sending the JSON wrong, this is the JSON object I'm sending:</p>
  
  <pre><code>{posttext: "What is your earliest memory of WWII?", linkdata: ""}
  </code></pre>
