Hi all,
I want to sort my objectValues('News') at date_add, the date that the
News objects were added.
I have written a python method to do this:
def list_peers(self, sortkey='id'):
        """returns a listing of peer news objects sorted on sortkey"""
        itemlist = []
        for item in self.REQUEST['PARENTS'][1].objectValues('GNAW'):
            itemlist.append(
                (getattr(item,sortkey),item)
                )
        itemlist.sort()
        return itemlist
I can give the sortkey as an argument to the method.
Now I want to implement this in ZPT as follows:
<div tal:define="itemlist python:here.list_peers()">
<div tal:repeat="item itemlist">
    <a href="#"
    tal:attributes="href item/absolute_url"
    tal:content="item/title">Title news</a> </div>
</div>
But this doesn't work. What am I doing wrong?
maybe
<div tal:define="itemlist python:here.list_peers(id='date_add')">
?
ähem, typo
<div tal:define="itemlist python:here.list_peers(sortkey='date_add')">
