[Lift] Re: How to create an rss?
Hi Glenn
thanks for your reply. It seems to work for me :-) I was confused
between AtomResponse, Box[NodeSeq] and LiftResponse. I am at beginning
of this journey.
regards,
wibblecp.

[Lift] Re: How to create an rss?
I don't know if this will help, but I use a simple createTag to just
enclose the full xml so it has a root element:
def createTag(in: NodeSeq) = {
{in}
}
and then showArticles would call into a feed wrapper, passing in the
result of yield, like this for an Atom feed:
//Reacts to Get all reguest
def showArticles():AtomResponse = {
val eList = for(e <- Content.findAll) yield {
e.toAtom
}
AtomResponse(feedWrapper(eList))
}
