title: Unable to sum task actuals using VersionOne Python SDK
body: <p>Using the Python SDK for VersionOne, I'm trying to sum the actuals for each task.  Here's my best guess at how to do this.</p>
  
  <pre><code>term="Actuals:Actual.Value.@Sum"
  
  for task in v1.Task.select("Name",term).filter("AssetState!='Dead'"):
      print(task.Name,task.data[term])
  </code></pre>
  
  <p>First, the <code>task.data[term]</code> bit is based on the docs, but there's no such key.  The closest key in the returned task is <code>"Actuals:Actual"</code>.</p>
  
  <p>Second, using that as the key instead seems to work for tasks that have no actuals, although instead of "0", I get an empty string.</p>
  
  <p>Finally, once I hit a task with some actuals, I get an <code>AttributeError</code> in <code>v1pysdk.v1meta.add_attribute_to_output()</code>, which is somehow using <code>"6"</code> (the <em>actual</em> actual) as a <code>base_asset</code>, calling its <code>with_data()</code> method.</p>
  
  <p>I'm able to get these sums using, e.g.,</p>
  
  <pre><code>&lt;server-base&gt;/rest-1.v1/Data/Task/1234/Actuals:Actual.Value.@Sum
  </code></pre>
  
  <p>so surely I'm close.  Is there a way to do this with the Python SDK?</p>
  
  <p>Thanks.</p>
