This is my controller which (attempts to) create the xml doc from the
database:
@expose()
def getDivisions(self, segmentid, *args, **kw):
def genAddElement( division ):
return """ <DIVISION>
<ID>%d</ID>
<NAME>'%s'</NAME>
<SEGMENTID>%d</SEGMENTID>
</DIVISION> """ % ( division.divisionid, division.name,
division.segmentid )
divisions =
DBSession.query(Division).filter(Division.segmentid==int(segmentid)).order_by(Division.name).all()
xmlElements = map( genAddElement, divisions )
xmlStr = string.join( xmlElements, '\n' )
xmlDoc = """ <?xml version='1.0' encoding='ISO-8859-1'?>
<DIVISIONS>
%s
</DIVISIONS> """ % (xmlStr)
return xmlDoc
My javascript goes something like this:
function updateDivisions()
{
var XMLHttpRequestObject = false;
if (window.XMLHttpRequest)
{
XMLHttpRequestObject = new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
XMLHttpRequestObject = new ActiveXObject('Microsoft.XMLHTTP');
}
if(XMLHttpRequestObject)
{
var segCtrl = document.getElementById('segment');
var segVal = segmentCtrl.options[segmentCtrl.selectedIndex].value;
XMLHttpRequestObject.onreadystatechange = function()
{
if (XMLHttpRequestObject.readyState == 4)
{
if (XMLHttpRequestObject.status == 200)
{
xmlDoc = XMLHttpRequestObject.responseXML;
}
}
}
XMLHttpRequestObject.open('GET', "${tg.url('/sponsor/getDivisions/"
+ segVal + "')}");
XMLHttpRequestObject.send(null);
}
}
The XMLHttpRequestObject.status is returning 500 instead of 200.
I think it has something to do with the way I'm creating the xml doc. Is
there another way?
Thanks.
