[Lift] Re: higher-kinded types
All,
The following code works without going through the M-P-O construction. It
enjoys approximately the same brevity as a Haskell type class.
// smallest expression of monad i can find
trait MBrace[C[_] <: MBrace[C,A],A] {
def nest( a : A ) : C[A]
def flatten[T <: C[C[A]]]( bsq : T ) : C[A]
}
// one of the simplest witnesses of monad i can find
class MBraceSeq[A]( a_ : A* ) extends Seq[A] with MBrace[MBraceSeq,A] {
override def nest( a : A ) = new MBraceSeq[A]( a )
override def flatten[T <: MBraceSeq[MBraceSeq[A]]]( bsq : T ) :
MBraceSeq[A] = {
(new MBraceSeq[A]( ) /: bsq)( {
( acc : MBraceSeq[A], e : MBraceSeq[A] ) => ( acc ++ e
).asInstanceOf[MBraceSeq[A]]
} )
}
override def length = a_.length
override def elements = a_.elements
override def apply( n : Int ) = a_.apply( n )
}
Best wishes,

[Lift] Re: date management
OK, things are working well with RequestVar, but now I need to know
how to kill it!
After I create and save my record, if I refresh the browser, I get
another record created. I did a temporary hack-fix with:
if(! myRecord.saved_?)
but I would just like to kill the RequestVar after the first round of
record creation-saving.
In terms of your example above, how would I do that?

[Lift] Getting Username and Password from URL of form hxxp://user:passw...@foo.org
I can't seem to find anyway to get to those two values. I've been searching all over the request class/object and no luck. I'm writing a RESTful web service that uses basic auth and for some reason jQuery likes to send things in the above mentioned format (http://user:passw...@foo.org). I've tried to fix that on the Javascript side but I couldn't get anything to work. So instead I decided on the service to recognize either the header style or the URL style of passing the login info. Sounded simple enough, until I couldn't find how to get at that/those strings.. Any help would be greatly appreciated..

Try upgrading your hibernate version from 3.3.1.ga to 3.3.2.GA.
Derek, can you look into upgrading the archetype to this release as
well? I recall 3.3.1.ga having some packaging issues.

[Lift] Re: JPA and auto generation of id
Thanks for all the answers guys.
I managed to fix the id problem, I needed the Hibernate specific class
GenericGenerator to fix it, which of cource is less pretty then using
only JPA. Someone has an example of how to make it work with MySql and
only JPA annotations? Current version:
@Entity
class Scene {
@Id
@GenericGenerator{val name="hibernate-increment", val
strategy="increment"}
@GeneratedValue{val strategy = GenerationType.SEQUENCE, val
generator = "hibernate-increment"}
var id : Long = _
@Column{val unique = true, val nullable = false}
var ordering : Int = _
@Column{val unique = true, val nullable = false}
var name : String = ""
@ManyToOne{val optional = false}
var storyBoard : StoryBoard = _
}
However, now I get an org.hibernate.PropertyValueException: not-null
property references a null or transient value:
model.Scene.storyBoard :-s I tried a lot of things already, the
corresponding StoryBoard is saved and not null, so I guess it has to
be transient. Merging the StoryBoard however still gives the same
error..
I tried to get JPA and Lift working together in the same way as in the
JPADemo example.. Is it the use of MySql which prevents the example
from working for me?
regards,
David

[Lift] Re: Stax
I was able to get the latest lift-example application deployed without a problem: http://helloworld.hoffrocket.staxapps.net/. It's running against a mysql DB that they're hosting, not h2. I got an nginx 502 gateway down with a more substantial app, but their log files were all blank, so I have no idea what the problem was. Their deployment mechanism is war/ear based (ear built locally, then uploaded). It would be cool if they supported standard mvn layouts and could just build your war from source. I'm on a 512kb max upload and lift-example took 5 minutes to deploy. - Jon On Jun 24, 4:21 pm, Tim Nelson wrote: > I think they use Gant.http://gant.codehaus.org/ > > > > On Wed, Jun 24, 2009 at 3:10 PM, fan...@gmail.com wrote: > > > Tim Nelson a écrit : > > [...] > > > I did install their SDK and from what I can tell it's basically some > > > Groovy scripts that use Ant + Ivy. > > > Gradle perhaps ?http://www.gradle.org/ > > > -- > > Francois Armand > >http://fanf42.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: New mapper class: MappedEnumString
Looks very nice.
One thing I'm wondering, what if I wanted the displayed value outside of the
mapper, such as TestTypes.Item1.displayValue. Would you use an implicit
conversion to provide this or is the
display value conceptually always part of a mapper object.
I have a rough implementation called EnumWithDescription, that wraps (not
extends) an Enumeration
and provides a description method on the enumeration value without using an
implicit. I'm wondering
if it might be useful to combine your approach and mine?
cheers

[Lift] Re: Anyone working on the flot widget?
Hi Jeppe Great to see you are interested in the flot widget. My current to-do list for the flot widget, is: - create more Lift JsExp and JsCmd to modify a already displayed flot graph. They should be used in AJAX and Comet applications - update to a more recent version of the javascrrit widget - create the test demo app, - make the creation of FlotOptions, FlotLinesOptions, etc, less verbose. I hope that Scala 2.8 Named and Default Arguments will help. - create a high level mechanism to display Lift's Record I appreciate any help.

[Lift] New mapper class: MappedEnumString
Hi,
A while ago, I asked if it was possible to use something like MappedEnum
and have some sensible values inserted into the database instead of
integers.
I got the feeling this was not the case, so I've created MappedEnumString
(attached) which maps Enumerations into string values.
Example:
object TestTypes extends Enumeration {
val Unknown = new Val(0,"??")
val Item1 = new Val("XX")
val Item2 = new Val("YY")
}
object test extends MappedEnumString(this, TestTypes, 2)
This will store the values, ??, XX or YY in the db. For display
purposes, it will by default lookup the resource values TestTypes.??,
TestTypes.XX, TestTypes.YY
You can also calculate the displayed values:
object test2 extends MappedEnumString(this, TestTypes, 2) {
override def _valueToDisplayString(v:Enumeration#Value) = v match {
case TestTypes.Item1 => "Item1Display"
case TestTypes.Item2 => "Item2Display"
case _ => "Unknown x ItemDisplay"
}
}
I'm by no means a Scala/Lift expert so I may have overlooked stuff, so
feel free to comment :-)

[Lift] Re: Stax
Although it's not in the docs, they do have a Lift 1.0 template that's at: http://stax-downloads.s3.amazonaws.com/app-templates/0.3/lift-1.0.zip This is normally downloaded automatically by their SDK, but you can download it directly if you want to see what's in it without installing the SDK. I don't see any reason that one couldn't make a new Maven archetype that is Stax compatible. However, it appears that, currently, you are required to use their SDK to deploy apps. This was intentional on their part as they were worried users would be turned off if they tried to load existing apps and had problems with them, since there are certain limitations. There are problems with Grails apps at the moment because it has it's own build system that conflicts with Stax's SDK and they are working on an API that would allow using a separate build system that calls the Stax API for deployment. This would probably allow for a Maven plugin to be built for deploying Stax apps. There's more details in this post from their forum: http://developer.stax.net/forum/topics/grails-help-me-and-i-can-help I did install their SDK and from what I can tell it's basically some Groovy scripts that use Ant + Ivy.

If you look at the source to CRUDify, you'll see
def viewTemplate(): NodeSeq = pageWrapper(_viewTemplate)
where
def pageWrapper(body: NodeSeq): NodeSeq =
{
body
}
def _viewTemplate =
So the simplest thing is to override _viewTemplate with something similar
to the above. This should be done on the companion objects where CRUDify
is mixed in

[Lift] Re: Another backtrace on reload
I had the same problem a while ago. I'm not sure if I fixed it then, but I think it had to do with the db still being open possibly. When the code changes does the servlet get undeployed? You might need to run derby in server mode. Lately I've been launching jetty without maven, and to get it to reload eclipse calls an ant script that touches the context.xml. I'm using h2 in tcp mode. Another option is JavaRebel which often obviates the need to redeploy.

[Lift] Re: Modify CRUDify XHTML
Well, it's the viewTemplate method, but it's supposed to return a NodeSeq,
so if you're pulling from a file you'll need to do the file load yourself.
You can do that with LiftRules.loadResourceAsXml:
...
override def viewTemplate = LiftRules.loadResourceAsXml("foo") openOr
Error loading template
...

[Lift] Re: So where is that OAuth?
I've been working on the provider side of oauth to authenticate api
calls.
I was looking at the http-authentication example, but I'm not sure if
want to go that route. I would like to be able to specify
authentication for paths in the same place that I define them (in a
DispatchPF).
I'd also like to be able to pass down a Box[(consumer, Box[token])] to
my response functions.
This is what I have so far. I'm fairly new to scala/lift, so any
pointers would be appreciated:
object RestAPI extends XMLApiHelper{
//OAuth takes to functions for looking up the secrets
associated with the consumer and token keys
//trivial functions here for testing, but would be replaced
with DB call
val oauth = OAuth(c => c, t => t)
def dispatch: LiftRules.DispatchPF = {
case Req(List("api","user",userid), "", GetRequest) =>
() => requireToken(showUser(userid))
}
def showUser(userid: String) (consumer: Consumer, token: Token):
LiftResponse = {
val e: Box[NodeSeq] =
for(r <- User.find(userid.toLong)) yield {
r.toXML
}
e
}
def unauth(message: String) = new XhtmlResponse(
{message}, Full("text/xml"),
Nil,
Nil,
401, false)
def requireToken(f: (Consumer, Token) => LiftResponse):
LiftResponse = {
oauth.verify_signature match {
case Full((c, Full(t))) => f(c, t)
case _ => unauth("Authentication failed")
}
}
def requireSigned(f: (Consumer) => LiftResponse): LiftResponse = {
oauth.verify_signature match {
case Full((c, _)) => f(c)
case _ => unauth("Invalid oauth signature")
}
}
}

[Lift] Modify CRUDify XHTML
Hi all, I'm using CRUDify on one of my models and I'd like to display some additional data on the view template. I believe that I need to override one of the model definitions with some sort of reference to my own XHTML file. Which one? _viewTemplate? Or perhaps the viewTemplate method?

Yes. Since it's a full template and not a fragment (using ) it has to conform to normal XML rules. In particular, XML can only have one root element.

The error was occurring if you had more than a single root element. Thus: works whereas caused the "template not found" erroneous exception before David fixed it. Thanks David!

[Lift] Re: [scala] JPA question
Well, in my real-world experience I've never had very complex models and
I've never used TABLE-PER-CLASS either, so I don't really have a feel for
what's not possible. Generally I think that JPA (which is a subset of
Hibernate) covers a good portion of people's needs for ORM, but it
definitely has some big missing functionality (e.g. no ordered collections
until JPA 2). I think that in this case Greg is pushing the limits on a
relatively unused corner of JPA (I've never seen someone use TABLE-PER-CLASS
before) and he's hitting some bugs. I want to make clear that I think that
what Greg is attempting is entirely possible. My earlier comment about
rolling your own ORM was because I misunderstood what he was doing with
abstract classes. In my mind, there would be a couple of places where you
might want to roll your own stuff:
1. An existing schema that doesn't map well to an object graph. We have a
legacy database at work where the brilliant developers decided that nothing
should be normalized and data can exist in one of four tables based on some
arcane business logic. You can still build an ORM layer on something like
this, but essentially all you're doing is creating a thin wrapper on
ResultSets
2. You have very specific data that you need to retrieve with possibly
complex joins, and you need it to be as performant as possible. There are
some tricks you can do with EJB QL to make it prefetch things, but often you
can end up with multiple round trips to the database and/or data that you
don't need being fetched. In certain scenarios I could see this being an
issue.
This list isn't intended to be exhaustive, these are just the top two that
come to mind. In terms of Hibernate vs others like JPOX, TopLink, etc, I'd
say that Hibernate is a first-class provider and at least equal to the
others.

The line is blurring. With EJB 3.1 (Java EE 6) there is talk of using various profiles so that you can essentially deploy a WAR file that bootstraps a subset of an application server feature set within a servlet container. OpenEJB already does something like this: http://openejb.apache.org/ Derek On Tue, Jun 23, 2009 at 1:54 PM, Jeppe Nejsum Madsen wrote: > > On 23 Jun 2009, Naftoli Gugenhem wrote: > > > > What's the difference between an application server and a servlet > > container? > > Depends on who you ask :-) Application server usually means a J2EE > implementation which support things such as EJBs, message services, > transaction monitors, database pools (and a servlet container). > > A servlet container, as the name implies, is a service that can be used > to host servlets. > > So while applications can run using only a servlet container, an > "application server" typically means a servlet container and a lot of > extra services which you may or (most likely) may not need. > > /Jeppe > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: Submenus for model-generated views
I haven't looked at the CRUDify trait in a while, but I think that what you
want is something like:
val entries =
Menu(Loc("Home", List("index"), "Home")) ::
Menu(Loc("Layous", Layouts.listPath, "Layouts", Layouts.menus: _*) ::
User.sitemap
Using the listPath method makes sure that you match the actual prefix and
path. In your case, the class is "Layouts", which by default results in a
"Layouts" path prefix, but in your code you're using "layout". If you're
overriding the table name to "layout" then your code should be working, I
think. Also, List and Create are the only two links that should be shown,
but I'm not sure that the current CRUDify code makes the delete, edit and
view Menus hidden.

I would put these Hidden items on the specific menu items rather than
matching against a path. Locating Hidden with the items to be hidden will
help you and other developers see what the non-global rules are.

This could be case _ if User.loggedIn_? => or case Full(_) if
User.loggedIn_? =>

If the menu building takes place inside the scope of a CometActor. There
are times when Lift does stuff outside of the scope of a specific request.
It's unlikely that this will happen in the normal case, but it could happen
(e.g., someone updates menus in a CometActor).

Oh... I get why you did the Hidden thing... I'd do the following:
case Full(Req(path, _, _)) if !User.loggedIn_? && path != List("profile",
"login") && path != path != List("profile", "lost_password") =>
Loc.EarlyResponse(() =>
Full(RedirectResponse("/profile/login?returnTo="+S.uri)))
If you prefer to do the pattern matching thing, you can return:
new Loc.LocParam{}
That's a noop.

[Lift] Re: Is there any eclipse setup that actually works for lift?
Hello Everyone, Thanks for all your suggestions and the version numbers -- I'll give them a try. I tried NetBeans 6.7RC3 yesterday, btw, but its maven+scala support has a major bug with regard to compiler errors, so it's no better than my experience with Eclipse at this time.

[Lift] Thead safe part and transaction management in Lift
Hello guys, I'm following my path through lift, and there is some part that are still not really clear for me. First question: what parts of lift are thread safe ? In particular, does the request/response handling cycle is thread safe ? I thing so, but I didn't found any doc that assert that. Second question: how transaction are handled with Lift default ORM layout ? I'm didn't see how we declare a transaction, and especially how one can handle rollbacks. Any inputs or links toward resources answering these two points would be much appreciated !

Would you distinguish between what is achievable in a specific ORM

[Lift] Anyone working on the flot widget?
Hi, We need to do quite a lot of charting in our app and after evaluating several libraries we've settled on Flot (for now at least :-) So I was happy to discover there was already some Flot integrations in Lift. After having looked a bit at this, it seems there are some things missing that we would need: 1) Better support for barcharts (ie specifying data series as (label, value)) 2) Support for pie charts (patches exists for the JS part) But before diving into this I thought to ask if anybody is already working on the flot widget (or has other ideas for the Flot stuff) /Jeppe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

Brilliant! Works nicely. I ended up with this
val menuDispatch:List[PartialFunction[Box[Req], Loc.LocParam]] = List({
case Full(Req("profile" :: "login" :: Nil , _, _)) => Hidden
case Full(Req("profile" :: "lost_password" :: Nil , _, _)) => Hidden
case Full(Req(_, _, _)) if !User.loggedIn_? => Loc.EarlyResponse(() =>
Full(RedirectResponse("/profile/login?returnTo="+S.uri)))
})
A couple of questions:
1) Why the need for Box[Req]? When will it be Empty?
2) In the above I had to use Hidden as a dummy value to signal no
Loc. It might be useful with a Box[Loc.LocParam] as return value?
