You can also use the excellent lift-json libraries to parse the XML and

[Lift] Re: Basic RESTful webservice with LIFT compile error "... since method createTag in trait XMLApiHelper ..."
Hi David, thanks for the response.
Thanks, that gets it compiling, and I think I see what it does.
Is the right way to proceed if I want to return JSON (rather than
XML)?

[Lift] Re: Basic RESTful webservice with LIFT compile error "... since method createTag in trait XMLApiHelper ..."
In order to use the XMLApiHelper trait, you must define an outer-most XML
Elem that will wrap the response.
For example:
def createTag(in: NodeSeq): Elem = {in}
Now... if your stuff already does the wrapping in the outer-most Elem, you
can do:
def createTag(in: NodeSeq): Elem = in.flatMap{case e: Elem => List(e) case _
=> Nil}.firstOption getOrElse

[Lift] Re: Basic RESTful webservice with LIFT compile error "... since method createTag in trait XMLApiHelper ..."
I noticed that other examples use a singleton object instead of class,
so I changed my code, but I just get the same sort of error but for an
object:
object creation impossible, since method createTag in trait
XMLApiHelper of type (scala.xml.NodeSeq)scala.xml.Elem is not defined
RestAPI.scala /poc/src/main/scala/com/somecompany/api Unknown Scala
Problem

[Lift] Basic RESTful webservice with LIFT compile error "... since method createTag in trait XMLApiHelper ..."
I'm getting started with Scala and Lift, implementing a simple REST
service. I've extended XMLApiHelper, following examples in "Exploring
Lift", but I'm getting a compile error I'm not sure about, any
suggestions?
error:
class RestAPI needs to be abstract, since method createTag in trait
XMLApiHelper of type (scala.xml.NodeSeq)scala.xml.Elem is not defined
RestAPI.scala /poc/src/main/scala/com/somecompany/api Unknown Scala
Problem
So its telling me I have to implement createTag... but, I don't know
how to :) Also, the examples i've seen don't seem to implement it,
making me think I'm doing something wrong.
package com.somecompany.api
import _root_.net.liftweb.util._
import _root_.net.liftweb.http._
import Helpers._
import net.liftweb.http.rest.XMLApiHelper
class RestAPI extends XMLApiHelper {
def dispatch: LiftRules.DispatchPF = {
case Req(List("api", "camera", cameraId), "", DeleteRequest) =>
() => deleteCamera(cameraId)
// Invalid API request - route to our error handler
case Req(List("api", _), "", _) => failure _
}
def failure : LiftResponse = BadResponse()
def deleteCamera(cameraId : String) : LiftResponse = {
NoContentResponse()
}
}
Thanks!

[Lift] Compile error with 1.1-M1 and CRUDify
Hi,
I saw the following after moving my project from lift 1.0 to 1.1-M1:
[WARNING] self-type com.company.model.City does not conform to
net.liftweb.mapper.CRUDify[Long,com.company.model.City]'s selftype
net.liftweb.mapper.CRUDify[Long,com.company.model.City] with
com.company.model.City with net.liftweb.mapper.KeyedMetaMapper
[Long,com.company.model.City]
[WARNING] class City extends LongKeyedMapper[City] with IdPK with
CRUDify[Long, City] {
I fixed by moving the CRUDify trait from the class to the meta object
definition. Is that correct usage?
Was the CRUDify trait always supposed to be used on the meta object
(the liftbook example shows the trait on the class)?
Thanks,
Jon

[Lift] Compile error in TD.scala whith example in "Starting with Lift" HTML guide
Good morning, Scala has been getting some interest in the project I work with, and I've been asked to investigate the Lift framework as a possibility to migrate our custom coded website to it. I'm a Scala newbie, so I'm working on absorbing a lot in a short period of time. I'm having problems with the "Stating with Lift" found at: http://liftweb.net/docs/getting_started/mod_master.html I was able to get everything working up through section 2.8. I'm getting stuck in Section 2.12 where it suggests starting the server and trying the changes from Section 2.9. Specifically I'm getting hung up with a compile time error with TD.scala. First I get these two errors: $ mvn jetty:run ... [INFO] Checking for multiple versions of scala [INFO] Compiling 3 source files to /Users/danielmckagan/Workspaces/ lift-test/todo/target/classes [WARNING] /Users/danielmckagan/Workspaces/lift-test/todo/src/main/ scala/com/liftworkshop/model/ToDo.scala:29: error: ')' expected but integer literal found. [WARNING] valMinLen(3, ~Description must be 3 characters~) _ :: [WARNING] ^ [WARNING] /Users/danielmckagan/Workspaces/lift-test/todo/src/main/ scala/com/liftworkshop/snippet/TD.scala:33: error: ')' expected but '.' found. [WARNING] ~priority~ -> todo.priority.toForm, [WARNING] ^ [WARNING] two errors found ... If I change the '3' to 'three' in the first example, that error falls away and the second one remains: ...

[WARNING] ~priority~ -> todo.priority.toForm, [WARNING] ^ [WARNING] one error found ... And I can't figure out how to get over it. I deleted the entire todo project and started from the beginning, cutting and pasting the examples, and have gotten the same behavior both times. This may help... $ mvn --version Apache Maven 2.1.0 (r755702; 2009-03-18 12:10:27-0700) Java version: 1.5.0_16 Java home: /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/ Home Default locale: en_US, platform encoding: MacRoman OS name: "mac os x" version: "10.5.6" arch: "i386" Family: "unix" Any help would be appreciated, Dano! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.
