[Lift] Re: json extraction problem
Hi,
I pasted this to scala console and it worked. I am pretty sure that
the problem is that your case classes are inner classes. Inner classes
get one extra implicit constructor parameter, a reference to the outer
class (same way as in Java). You need to move those case classes away
from enclosing class (to an object or package etc.).
The error message is very bad in this case. I will fix it.
Cheers Joni

[Lift] Re: Concurrent Web Service Requests?
Well I said what I had to say. My problem is not really the prefix
name but the existence of other prefixes then lift, that are
interpreted by lift. It's just how I see things now and nothing on
this thread provided sufficient arguments to convince me
otherwise ...
not much else for me to do if majority and especially DPP thinks
otherwise. It is what it is I guess.

I think everyone agrees in concept, that an arbitrary prefix sets a bad
precendent, which is why it is no longer do:par. But on the other hand, if
the part after lift: is either a reserved word or a user word--a snippet
name--then the more reserved words, the more you limit snippet names. (Should
S.mapSnippet(parallel, ...) throw an exception?)
So we have these two considerations on either end of the spectrum. Arguably,
liftx as a prefix satisfies both--it is sufficiently generic to include
almost any special attribute that may be added, it clearly spells out
extended lift attribute, and on the other hand it keeps reserved lift
attributes separate from the user's snippet namespace.
Now let's bear in mind that this is all only relevant in the future, when
lift: attributes indeed will be interpreted as lift:snippet=... is now. At
that point it might make sense for the explicit :snippet format to be moved
to the liftx prefix-- liftx:snippet=... --for the same reason, not to
encroach on the snippet namespace.

it is more about clarity. We add a new prefix now, tomorrow add

and mix things up. To me lift prefix is enough and quite clear. It is
more than just s snippet thingy. It tells the user hey this thing is
telling the framework something and the framework is doing something
with it. It is separating framework xml markup from the actual xhtml
markup. Having a single reserved prefix promotes clarity and keeps
things simple and rather intuitive.
I'm not in favor of using unprefixed attributes like
par=something (btw I really don't like par naming :) ...) because
unprefixed attributes should be only standard xhtml ones or the ones
that user explicitly specifies it. So lift:parallel=true or
lift:async=true should be just fine.

Correct BUT lift:par or lift:parallel attributes are also applicable
to snippets context. They determine the snippet's execution semantics.
So I'm still questioning the need for a new prefix.
I'm still for an eval: prefix, as these proposals all relate to how a
page is evaluated.

Personally I don't think so. Historically lift reserved prefix names
were heavily debated and argued and this is a little sensitive area.
But the good news is that I may be the only one feeling this way about
this and everyone else likes it so I'm just a negligible minority.

If you have a javascript function foo(a, b) where a is a String and b

JE.Call(foo, one, 2)
for example. If you wanted to set some variable to the result of the
function, you could do:
JsCmds.CrVar(myVar, JE.Call(foo, one, 2))

Thanks for your prompt reply.
As a beginner I have started reading the book Exploring Lift.

If you need to write large portions of JavaScript code for your

pure JavaScript in an external file and then including that file in
your pages. In particular, if you write your code as JavaScript
functions, you can use the JE.Call class to execute those functions
from your Lift code.
I just want to know how can I use JE.Call function fro my external

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
A quick look at the code... you use open_! That's considered very bad practice. Any time you use open_!, you are saying I know this thing contains a value. It's like not doing null testing when the method you are calling is expected to return a null under certain circumstance. Put another way, the ! is in the name for a reason. It's dangerous... think before using.

This is off topic, but you always are a help. Your
thoughtful assistance on this discussion group either directly
resolves issues I'm
having with Lift, or leads me to rethink my strategy and explore new
avenues
I haven't thought of. At the very least, you force me to reframe many

Many times, I've thought of abandoning Lift for safer harbors, but

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Hi Tim, This project is meant as an example for people (like me) that maintain existing Spring architectures and are interested in using Scala and Lift. What I want to do now is port the existing jsp's and spring controllers to lift, so that people can compare jsp and lift-webkit with each other (and probably favor lift :) ). Currently I have just looked at the easiest way to integrate Lift and Spring (that is using the LiftFilter and access Spring's ApplicationContext), but I am also interested in other ways to integrate them (at a later stage).

[Lift] Testing snippets that depend on a user logged in
I have a class called
class Trainer {
def showPeople(xhtml : Group) : NodeSeq = {
val user : User = User.currentUser.open_!
...
}
}
I then want to write a unit test to test that returns proper xml.
The test is written as so
def testValue() = {
val xml =
xml:group
tr
td
p:fullNameMy Name/p:fullName
/td
td
p:styleFighter Style/p:style
/td
td
p:weightWeight/p:weight
/td
/tr
/xml:group
val trainer = new Trainer()
val output = trainer.showPeople(xml)
()
}
The User object inherits from MegaProtoUser.
The problem is I am not sure how to create a mock user and sign them
in.
I have tried in my unit test
override def setUp : Unit = {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
}
The mock user log-in *seems* to work fine but when
User.currentUser.open_! is called it throws an exception on trying to
open an empty box.
So either how do I do this or how do others do this type of testing.
I am sure I am missing something simple.
Thanks,
ryan

[Lift] Re: Concurrent Web Service Requests?
Marius, I have a ton of respect for your opinion and I appreciate your analysis. I have been following this thread and thinking, what does the lift: prefix mean? In my mind, it means this thing will be changed based on evaluating some code. So, using the lift: prefix for something that also means this modifies the meaning of this snippet invocation presents something discordant to me. With that being said, I'm going to hand the decision to you. I trust your decisions and have concerns about my own instincts when it comes to naming. Please update the code to reflect what you think it should be and merge it into master. Thanks, David On Thu, Oct 1, 2009 at 5:58 AM, marius d. marius.dan...@gmail.com wrote: Well I said what I had to say. My problem is not really the prefix name but the existence of other prefixes then lift, that are interpreted by lift.

But on the other hand, if the part after lift: is either a reserved word or a user word--a snippet name--then the more reserved words, the more you limit snippet names. (Should S.mapSnippet(parallel, ...) throw an exception?) So we have these two considerations on either end of the spectrum. Arguably, liftx as a prefix satisfies both--it is sufficiently generic to include almost any special attribute that may be added, it clearly spells out extended lift attribute, and on the other hand it keeps reserved lift attributes separate from the user's snippet namespace. Now let's bear in mind that this is all only relevant in the future, when lift: attributes indeed will be interpreted as lift:snippet=... is now. At that point it might make sense for the explicit :snippet format to be moved to the liftx prefix-- liftx:snippet=... --for the same reason, not to encroach on the snippet namespace. - marius d.marius.dan...@gmail.com wrote: It has been debated many times in slightly different contexts. To me it is more about clarity. We add a new prefix now, tomorrow add another one and so on. People would have to remember what goes where and mix things up. To me lift prefix is enough and quite clear. It is more than just s snippet thingy. It tells the user hey this thing is telling the framework something and the framework is doing something with it. It is separating framework xml markup from the actual xhtml markup. Having a single reserved prefix promotes clarity and keeps things simple and rather intuitive. I'm not in favor of using unprefixed attributes like par=something (btw I really don't like par naming :) ...) because unprefixed attributes should be only standard xhtml ones or the ones that user explicitly specifies it.

The User object inherits from MegaProtoUser.
The problem is I am not sure how to create a mock user and sign them
in.
I have tried in my unit test
override def setUp : Unit = {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
}
The mock user log-in *seems* to work fine but when
User.currentUser.open_! is called it throws an exception on trying to
open an empty box.
So either how do I do this or how do others do this type of testing.
I am sure I am missing something simple.
Thanks,
ryan

One of my criteria for a Record class is that it must be able to translate itself to/from HTML forms (as well as XML and JSON). If you can find a way for Record to play nicely with HTML form generation in with lift-webkit and without it, cool. I'm all for it.

[Lift] Re: Testing snippets that depend on a user logged in
Hi Ryan,
It looks like you're currently using a JUnit TestCase. If you want an
easier port to something that would work you could use a ScalaTest
Suite like this:
import org.scalatest.Suite
class YourSuite extends Suite {
val session = new LiftSession(, randomString(20), Empty)
val stableTime = now
override def withFixture(test: NoArgTest) {
S.initIfUninitted(session) {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
test()
}
}
def testValue() {
val xml =
xml:group
tr
td
p:fullNameMy Name/p:fullName
/td
td
p:styleFighter Style/p:style
/td
td
p:weightWeight/p:weight
/td
/tr
/xml:group
val trainer = new Trainer()
val output = trainer.showPeople(xml)
// seems like you need an assertion here...
}
}
A Suite considers methods that start with test as tests, like JUnit
3, except they don't need to result in Unit so you don't need an extra
() at the end. The withFixture method is an alternative to
beforeEach/afterEach, which are like JUnit 3's setUp/tearDown methods.
Each test gets passed as a function to withFixture, which is
responsible for executing the test by invoking the function. In this
case, it is executed in the context created by S. initIfUninitted.
This is ScalaTest 1.0, which is available as a SNAPSHOT right now but
should be released proper a week from Monday.

[Lift] Re: Testing snippets that depend on a user logged in
Hi David,
Thanks. I appreciate that. I was actually already planning to request
getting some ScalaTest examples in the Lift archetypes right after
ScalaTest 1.0 comes out (on Oct 12, if all goes as planned), and have
already arranged with David Bernard to put ScalaTest examples into
simple-archetype-simple.
I think it is great that we have three decent Scala-specific testing
tools already, specs, ScalaTest, and ScalaCheck, plus the trusty Java
tools JUnit and TestNG. People have a lot of choice, so it is good
that the archetypes would show some of the options. I would also
suggest we include a ScalaCheck example in the archetypes as well. I
can use ScalaCheck from one of the ScalaTest examples I submit if you
like that idea. The downside is that it would add one more dependency,
but really I think people should find out about ScalaCheck.

Hi Ryan,
It looks like you're currently using a JUnit TestCase. If you want an
easier port to something that would work you could use a ScalaTest
Suite like this:
import org.scalatest.Suite
class YourSuite extends Suite {
val session = new LiftSession(, randomString(20), Empty)
val stableTime = now
override def withFixture(test: NoArgTest) {
S.initIfUninitted(session) {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
test()
}
}
def testValue() {
val xml =
xml:group
tr
td
p:fullNameMy Name/p:fullName
/td
td
p:styleFighter Style/p:style
/td
td
p:weightWeight/p:weight
/td
/tr
/xml:group
val trainer = new Trainer()
val output = trainer.showPeople(xml)
// seems like you need an assertion here...
}
}
A Suite considers methods that start with test as tests, like JUnit
3, except they don't need to result in Unit so you don't need an extra
() at the end. The withFixture method is an alternative to
beforeEach/afterEach, which are like JUnit 3's setUp/tearDown methods.
Each test gets passed as a function to withFixture, which is
responsible for executing the test by invoking the function. In this
case, it is executed in the context created by S. initIfUninitted.
This is ScalaTest 1.0, which is available as a SNAPSHOT right now but
should be released proper a week from Monday.

[Lift] JSONParse.parse and List[Any]
Hi all,
Building off of a previous thread[1], I'm trying to parse a POST
request that contains JSON data. Specifically, I expect a JSON array
of JSON objects representing Packet model data and want to have a List
[Packet] at the end.
I am trying the following:
val packets = for {
JSONPackets - req.param(packets)
packet - JSONParser.parse(JSONPackets)
nodeId - packet.param(node)
node - nodeId.toLong
} yield {
val packet = Packet.create.node(node)
packet.save
packet
}
The problem is that JSONParser.parse returns a List[Any], so packet is
of type Any. I can try to convert packet to a Map with
packet.asInstanceOf[Map[String, String]], but this seems to just push
my type problems to the next line of code. I'm having a hard time
getting to the point where I have the Map[String, String] from which I
know I can extract values to create Packets, so I would appreciate
suggestions on how to do this.
This all seems quite complicated and I wonder if I'm missing an easier
way to do this. Is JSONParse the way to go, or should I switch to
Joni's lift-json stuff? I'm using 1.1-M5 but would be willing to
switch to 1.1-SNAPSHOT...
Thanks for your help.

[Lift] Re: Removing Scala Actors from Lift
Martin and Philipp, My immediate problem is: http://groups.google.com/group/liftweb/browse_thread/thread/b3783e24b8417521/f89548ba1fa70319?hl=enlnk=gstq=oome# This has been a persistent problem with Scala Actors and I identified it last year in November or December. Philipp did the 2.7.4 release which did not address the issue. The 2.7.5 release was supposed to address the issue, but the use of Lift Actors masked the issue until the above issue was raised. I left my 2.7.5 related discussions with Philipp with the impression that the java.util.concurrent library was being used for thread pooling rather than the FJ library. On this, I backed out the Lift Actor changes from powering Lift's CometActors (Lift Actors power the long polling part of Lift). On Wed, Sep 30, 2009 at 8:18 AM, martin oder...@gmail.com wrote: About actors in Scala 2.8: . they have been refactored substantially compared to what's in the 2.7.x branch . Philipp has sent mails about this to scala-internals (05/31) . Philipp has invited DPP to look at the refactorings in 2.8 (07/21) to which he responded positively. I responded politely. Granted this is not something I always do (note, I am not being facetious), but I simply said something like looks good to me. . The ForkJoinPool in 2.8 is completely different from FJTask in 2.7.5; it's the version that's going into JDK7. It has been battle-tested and should not suffer from any memory leaks. The reason why Scala actors use the FJ framework is performance, in particular on multi-core hardware. So we do not think it's a good idea to go back to java.util.concurrent, except maybe for applications with very specialized demands. Do you have specific benchmarks that justify the tradeoff of baking in an external library (that could be as buggy as the one that's currently baked into Scala) versus java.util.concurrent? We think the main problem was that lift depends on Scala 2.7.x, and that the actor refactorings have not gone into the 2.7.x branch. I did a code review of the 2.8 Actors. I am not convinced that Erik's meta-concerns were addressed. I will be happy to be more descriptive off-list. The result is that people have not noticed the changes. For example, most of the issues that Erik raises in his blog post no longer apply to Scala 2.8. Initially we wanted 2.8 to be out by now, but it's taken much longer than we have foreseen, because some of the problems were harder than initially thought. We are sorry to have left the 2.7 branch relatively unattended for so long. It's difficult for us, though, to provide the resources to support two diverging branches in parallel. More community support with backports etc could help. While this is a nice thought, given the choice between debating with EPFL as to whether my changes are good enough or doing a Lift Actor implementation, I will opt for continuing to develop and maintain the Lift Actor library. This gives Lift users the assurance that bugs will be fixed in a timely manner, that we can add features based on community need, and that we can work with other library authors to insure common interfaces. To fix the concrete issue at hand, we replaced FJTask with (a backport of) java.util.concurrent.ThreadPoolExecutor in the Scala 2.7.x branch, to be released as 2.7.7. That takes care of the memory leaks in FJTask. Now to the larger picture. We are not at all wedded to Scala actors here; after all it's just a library. If there are others which fulfill some needs better, great! But we have to be honest to avoid confusion. One of the main differences between Scala actors and lift actors and Akka seems to be that only Scala actors provide nested receives, so only Scala actors really let you avoid an inversion of control. Lift Actors allow for changing (and nesting) the message handler on a message-by-message basis and because the handler can be defined within a given partial function, it can close over the variables visible in that partial function. Granted the syntax for doing so in Scala Actors is much more pleasing, the functionality exists with Lift Actors. This is a feature which complicates the implementation considerably, and that's what all our main results are about. You might not care about this particular feature in your code, and consequently you might choose a different abstraction. But calling that abstraction simply `actors' causes unnecessary confusion, in our opinion. Quoting from Wikipedia http://en.wikipedia.org/wiki/Actor_model: An actor is a computational entity that, in response to a message it receives, can concurrently: - send a finite number of messages to other actors; - create a finite number of new actors; - designate the behavior to be used for the next message it receives. Lift Actors do all of these things. I think it's a great thing that Philipp and the EPFL team introduced Actors to the JVM and Scala
[Lift] Re: Testing snippets that depend on a user logged in
Hi,
I am working at the moment on a small lift demo app and I've added
some enhancements to specs in order to ease the testing inside a
session.
To use those functionalities, you need specs-1.6.1-SNAPSHOT (http://
www.scala-tools.org/repo-snapshots/org/scala-tools/testing/specs/1.6.1-SNAPSHOT).
Here are the specification and traits that I use to test the JPA
requests to save a User in the database:
// First I create Mocks for the lift session
import javax.servlet.http._
import net.liftweb.http.{ S, Req, LiftSession }
import org.specs.mock.Mockito
trait MockRequest extends Mockito { this: Specification =
var request = mock[Req]
var httpRequest = mock[HttpServletRequest]
var session = mock[LiftSession]
def createMocks: Unit = {
request = mock[Req]
httpRequest = mock[HttpServletRequest]
session = mock[LiftSession]
request.request returns httpRequest
}
// this method can be used to executed any action inside a mocked
session
def inSession(f: =Any) { S.init(request, session) { f } }
def unsetParameter(name: String) { request.param(name) returns
None }
def setParameter(name: String, value: String) { request.param
(name) returns Some(value) }
}
// Context creation for the specification
//
// This Specification context specifies the User table must be
cleaned up before each example.
// It also makes sure that the example expectations are executed in a
mocked session
// see
http://code.google.com/p/specs/wiki/DeclareSpecifications#Specification_context_(_from_1.6.1_)
for more information
object DatabaseContext extends Specification with Contexts with
MockRequest {
val setup = new SpecContext {
beforeExample(inSession(Users.createQuery(delete
User).executeUpdate)) // delete the User table before each example
aroundExpectations(inSession(_)) // execute each example inside a
mocked session
}
}
// and finally the specification itself
import org.specs._
import org.specs.specification._
class UserSpec extends SpecificationWithJUnit with MockRequest with
Contexts {
DatabaseContext.setup(this) // set the specification context on this
specification
A Users repository can {
create a user in {
val eric = User(etorreborre, password, Eric)
Users.mergeAndFlush(eric) // the Users object is a LocalEMF
with RequestVarEM so it needs a session
Users.find(classOf[User], etorreborre) must_== Some(eric)
}
}
A Users repository should {
throw an exception if the user name has a length 5 in {
Users.merge(User(e, password, Eric)) must throwAn
[Exception]
}
}
}
I hope this helps too, please ask if you have any questions.
Eric.

I just want to know how can I use JE.Call function fro my external
javascript file and also how to use JE abstractions like (JsFunc,
ValById etc..)
Could you please provide a simple example so that my understanding
will be clear.
Thanks

It increments a counter.

[Lift] Re: Javascript Commands
Oops, sorry about that. Also, can you show a little more of your code? I'm
not sure what you're trying to do with the assignment to x.

If you have a javascript function foo(a, b) where a is a String and
b
is an integer then you can call that with
JE.Call(foo, one, 2)
for example. If you wanted to set some variable to the result of the
function, you could do:
JsCmds.CrVar(myVar, JE.Call(foo, one, 2))

Hi David,
Thanks for your prompt reply.
As a beginner I have started reading the book Exploring Lift.
It says
If you need to write large portions of JavaScript code for your
pages, we recommend writing that code in
pure JavaScript in an external file and then including that file in
your pages. In particular, if you write your code as JavaScript
functions, you can use the JE.Call class to execute those functions
from your Lift code.

[Lift] Re: Testing snippets that depend on a user logged in
Hi Ryan, David, Eric,
I added a ScalaTest version to your wiki page:
http://wiki.github.com/dpp/liftweb/how-to-unit-test-lift-snippets-with-a-logged-in-user
Eric you may want to add a specs version.

Awesome!!! Thanks guys for the help. It now works.
I put a how-to wiki document up on github. For me this was one of
those times where my google searches did not seem to turn up anything
fruitful, so I thought this how-to would be helpful. If it is not
helpful, then no hard feelings if the page is deleted. I just wanted
to give back.

Bill,
Thanks for posting this. I am, by experience (I started using it, I can use
it enough to write basic tests, I know no more) using Specs. I would
welcome and encourage some sample tests in Lift archetypes that use
ScalaTest. I want to make sure that folks who pick up Lift get to
experience ScalaTest as well as Specs... that way, folks who have a better
understanding of tests can make better choices.
Thanks,

Hi Ryan,
It looks like you're currently using a JUnit TestCase. If you want an
easier port to something that would work you could use a ScalaTest
Suite like this:
import org.scalatest.Suite
class YourSuite extends Suite {
val session = new LiftSession(, randomString(20), Empty)
val stableTime = now
override def withFixture(test: NoArgTest) {
S.initIfUninitted(session) {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
test()
}
}
def testValue() {
val xml =
xml:group
tr
td
p:fullNameMy Name/p:fullName
/td
td
p:styleFighter Style/p:style
/td
td
p:weightWeight/p:weight
/td
/tr
/xml:group
val trainer = new Trainer()
val output = trainer.showPeople(xml)
// seems like you need an assertion here...
}
}
A Suite considers methods that start with test as tests, like JUnit
3, except they don't need to result in Unit so you don't need an extra
() at the end. The withFixture method is an alternative to
beforeEach/afterEach, which are like JUnit 3's setUp/tearDown methods.
Each test gets passed as a function to withFixture, which is
responsible for executing the test by invoking the function. In this
case, it is executed in the context created by S. initIfUninitted.
This is ScalaTest 1.0, which is available as a SNAPSHOT right now but
should be released proper a week from Monday.

I have a class called
class Trainer {
def showPeople(xhtml : Group) : NodeSeq = {
val user : User = User.currentUser.open_!
...
}
}
I then want to write a unit test to test that returns proper xml.
The test is written as so
def testValue() = {
val xml =
xml:group
tr
td
p:fullNameMy Name/p:fullName
/td
td
p:styleFighter Style/p:style
/td
td
p:weightWeight/p:weight
/td
/tr
/xml:group
val trainer = new Trainer()
val output = trainer.showPeople(xml)
()
}
The User object inherits from MegaProtoUser.
The problem is I am not sure how to create a mock user and sign them
in.
I have tried in my unit test
override def setUp : Unit = {
val user = User.create
user.firstName(XXX)
user.lastName(YYY)
user.save
User.logUserIn(user)
}
The mock user log-in *seems* to work fine but when
User.currentUser.open_! is called it throws an exception on trying to
open an empty box.
So either how do I do this or how do others do this type
