pyexcel export error "No content, file name. Nothing is given"
<p>I'm using <code>django-pyexcel</code> to export data from the website, but when I go to the export URL I get the error:</p>
<blockquote>
<p>Exception Type: IOError</p>
<p>Exception Value: No content, file name. Nothing is given</p>
</blockquote>
<p>The code to export the data was copied from the <a href="http://django-excel.readthedocs.io/en/latest/#handle-data-export" rel="noreferrer">example</a> given in the documentation:</p>
<pre><code>return excel.make_response_from_a_table(Question, 'xls', file_name=&quot;sheet&quot;)
</code></pre>
