Hi Dick,
It looks like it is problems with Boxed vs. un-Boxed values. The error
you are currently seeing is because tagId is a Box[String] but By()
expects a String in that position. So you need to un-Box it. I'd
recommend changing
def followTag(tagId: Box[String]): LiftResponse = {
val ret: Box[Tuple3[Int,Map[String,String],Box[Elem]]] =
for (user <- User.currentUser)
yield {
val tag = Tag.findAll(By(Tag.name, tagId)).headOption
to
def followTag(tagId: Box[String]): LiftResponse = {
val ret: Box[Tuple3[Int,Map[String,String],Box[Elem]]] =
for (user <- User.currentUser)
yield {
val tag = Tag.findAll(By(Tag.name, tagId.openOr(""))).headOption
Calling the openOr() method on a Box will return the value inside the
Box (a String in this case), or if the Box is Empty it will return the
parameter passed to the method ("" in this case). Hopefully searching
for a blank string will not return any results, but please check for
that!
Once you make this change, you'll get a bunch more errors that we can
work through. Most of them are similar, revolving around Box or Option
and incorrect type signatures for functions. Let's work through these
one-by-one? I should be able to respond more quickly today.
Cheers,
Ethan
