Hi David,
There really are a lot of paths available with scala/lift, aren't
there?
After looking at what you wrote, here's what I came up with that works
well/is functional and compact, in case anyone else is wondering about
it.
def links(html:NodeSeq): NodeSeq={
Product.findActive.foldLeft(html) {
(html, prod) => bind("links",html,
"force_"+prod.product ->{x:NodeSeq => {<a href={"/forced?
product="+prod.product}>{x}</a>}}
)
}
}
Product is a JPA entity class, findactive returns a list of products.
If anyone has suggestions, please share.
Cheers,
Tim
