hi guys,
I'm looking for a way to generate an rss feed with lift, I'm working
on something like this (from lift-book):
object OwnRssFeed extends XMLApiHelper {
def dispatch: LiftRules.DispatchPF = {
case Req("rss" :: Nil, "", GetRequest) => () => showArticles()
case Req("rss" :: _ :: Nil, "", _) => failure _
}
def failure() : LiftResponse = {
val ret: Box[NodeSeq] = Full(<op id="FAILURE"></op>)
NotFoundResponse()
}
def createTag(in: NodeSeq) = {
println("[CreateTag] " + in)
<rss version="2.0">
<channel>
<title>title</title>
<link>http://example.org</link>
<description>Example.org</description>
<language>en-us</language>
<generator>Lift WebFramework</generator>
{in}
</channel>
</rss>
}
def showArticles(): LiftResponse = {
val a: Box[NodeSeq] = for(a <- Article.find(By
(Article.published, true))) yield {
a.toXML
}
a
}
}
obviously the yield into the definition of showArticles method break
the cycle to the first one.
Could you suggest me what I can do? I am evaluating lift and scala
just in a while.
Thanks for your attention.
w.
