[Lift] Re: New features
There are dependent types that mirror the parameterized types for Mapper, KeyedMapper, etc. I've updated ManyToMany to use the dependent types... it should eliminate the need to have the type parameters.

[Lift] Re: Custom Login
I think you could remove the User class/object pair from the app and replace
them with:
object LoginState {
object primaryKey extends SessionVar[Box[Long]](Empty) // the primary key
of the currently logged in user... change to Box[String] if the PK is a
String
object currentUser extends
RequestVar[Box[YourUserClass]](primaryKey.is.flatMap(key =>
lookupUser(key)))
def logUserIn(u: YourUserClass) {
currentUser.remove()
primaryKey.set(Full(u.getPrimaryKey))
}
def logUserOut() {
currentUser.remove()
primaryKey.remove()
S.request.foreach(_.request.getSession.invalidate)
}
def loggedIn_? = primaryKey.is.isDefined
}

[Lift] Re: SiteMap gives "No Navigation Defined."
Please look at the console output. If there's a stack trace generated
during the execution of Boot.scala, your app will be in an undefined state
and that may include the lack of a menu and/or title.

[Lift] Re: Rendering dynamic templates
First, you can associate a default template with a given Loc in SiteMap view the Loc.Template mechanism. Second, you can register a partial function with LiftRules.viewDispatch to render whatever dynamic content you want. Third (and this is the recommended solution for a CMS), you can use a snippet that examines current state and loads the correct template from the backing store. You can see an example of this in the wiki code that's in sites/example. Also, please remember that Lift snippets are recursive and lazily evaluated. This means that the XML returned by a snippet is run through Lift's transformation process so if your snippet returns , the foo snippet will be invoked.

[Lift] Re: Rendering dynamic templates
Yeah, finally i am getting better at finding this stuff out myself ;)
The dirty solution is to create an empty file named "empty.html"
templates-hidden and use this bind:
val res = sess.processSurroundAndInclude(
"empty",
bind("lift", ,
//XML.loadString(layout.layout),
"content" -> XML.loadString(content.content)
)
)
XhtmlResponse(res.first, Empty, Nil, Nil, 200, true)
Until we got something "real", this works! :)

[Lift] Re: Eclipse setup
I've found that simply closing all the open files and re-opening fixes some quirks. I'm using eclipse 3.5, IAM .10, scala 2.7.5, and javarebel-plugin 1.0.3 with javarebel 2.0.2b Is anyone else using javarebel with eclipse? I just run "RunWebApp" as a scala Application from within eclipse with javarebel. It works well when changing non-singletons-- Better than using jetty on a scanInterval which leaks permgen when it reloads the context. - Jon On Aug 6, 6:27 pm, Jonathan A Ferguson wrote: > See if the following configuration helps you as it solved most of my > problems. > > > http://blog.spiralarm.com/richard/2009/07/using-existing-scala-maven-... > > Cheers > Jono > > On 07/08/2009, at 6:44 AM, Steffen Weißmann wrote: > > > > > > >> You have two output folders: the Scala IDE <= 2.7.5.final only > >> supports one.

[Lift] Re: Rendering dynamic templates
Ok the problem is in src/main/scala/net/liftweb/bultin/snippet/
Surround.scala line 36:
#36 ctx.findAndMerge(S.attr.~("with"), paramsMap)
Here is the function which clearly needs a file to work with. u'll do
the bind by hand.
private[liftweb] def findAndMerge(templateName: Box[Seq[Node]],
atWhat: Map[String, NodeSeq]): NodeSeq =
{
val name = templateName.map(s => if (s.text.startsWith("/"))
s.text else "/"+ s.text).openOr("/templates-hidden/
default")
findTemplate(name) match
{
case f@ Failure(msg, be, _) if Props.devMode
=>
failedFind
(f)
case Full(s) => bind(atWhat,
s)
case _ => atWhat.values.flatMap
(_.elements).toList
}
}
I will post my solution later.

[Lift] Re: SOAP web services?
Myself and Viktor are two committers who do a lot of SOAP work - right now, the best route forward it to use the Java JAX-WS code and call into it with a scala wrapper - this is exactly what I do and it works perfectly. Because there is toll free calling of Java code, there is little point in porting such massive projects to Scala; just make a wrapper that suits your needs. In my environment I have about 40+ endpoints, with hundreds of methods so I just made a scala wrapper that lets me do: DriverManager.whateverdriver.myMethod(params) // Box[T] IMO, that's a damn lot easier than calling a boat load of Java (of course its doing the under the hood, but like I said, its just a wrapper).

[Lift] amqp library error
I'm trying to use lift-amqp library, so I created a maven test project (not Lift one, but just Scala with dependency to lift). I'm using Eclipse with maven-scala-plugin on Windows.

[Lift] Re: Rendering dynamic templates
It might be nice to make template loading configurable. Currently, TemplateFinder is used to load templates and it, in turn, uses LiftRules.finder to locate a resource by name from the classloader. I think that we could add a layer of indirection there to allow someone to use a partial function to determine where a template is loaded from, and provide a default impl that represents the current behavior. I'm thinking something like PartialFunction[(List[String],String),Box[NodeSeq]] One possible use would be for something like a CMS, with the template stored in a database. Thoughts?

I really would like to use eclipse, but right now i am using idea (even though I completely agree with David Pollaks blog posts...) since it usually understands the scala source code and it usually displays the lift code (and also other code) properly. I guess several people are developing lift projects with eclipse, so I hope there is a chance to get it working.

Actually, same thing doesn't happen. If I change the third argument,
I get this as the title in my browser as well as the link in the site
map.

[Lift] Rendering dynamic templates
Hi there, i was just wondering how one would go about dynamifying templates? Atm i store them on disk. Is there any way to parse a template and execute all the lift:MyStuff in that template? Like Xml.load but the way lift does it to render stuff in it. I tried to find it in code but didn't succeed. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

No Nav Defined typically shows up for me, when I've got my DB

[Lift] Re: How do I create a function that takes MetaMappers?
Naftoli's suggestion is good, but I think your problem now is that
User is not <: LongKeyedMapper, it's <: KeyedMapper. Here's one that
compiles:
object Test {
def findAll[T](m: KeyedMetaMapper[_, T]) = m.findAll
def test {
val users: List[User] = findAll(User)
users
}
}

Not sure why you're getting no nav, but I think you want to change the other
Home - the first string is the id of the link.

[Lift] SiteMap gives "No Navigation Defined."
Hello there,
I've been looking at SiteMap and trying to get it to give me a page
title, based on the SiteMap section in the Lift book (PDF version).

Boot.scala
// Build SiteMap
val entries = Menu(Loc("Home", "index"::Nil, "Home")) :: Nil
LiftRules.setSiteMap(SiteMap(entries:_*))
default.html
...
...
...
This works fine, and gives me "Home" as the title of my page.
Now I actually want a different title, so I change the Loc bit to Loc
("abcdefg", "index"::Nil, "Home") and get "No Navigation Defined."

[Lift] Re: Db.addLogFunc
Well, I started looking at it and determined that the only way for us to
truly log the queries would be to essentially make our own wrappers over
Statement and PreparedStatement. There are projects (log4jdbc, notably) that
already do this, and in a transparent manner. I'm not sure that adding a
whole bunch of SQL logging directly to Lift is better than leveraging some
existing libraries to do it.

[Lift] Re: Title function
I don't think I understand what you're getting at. The other option is to
use the Title LocParam. Given the code that I already wrote, you could do
something like:
Menu(Loc("Edit", List("edit"), "Edit", Hidden, Title(ignore =>
Text(Info.toEdit map ("Edit " + _.name) openOr "No item to edit!")))
The "ignore" parameter for the Title LocParam is used if you subclass Loc
and use type-safe parameters.

[Lift] Re: Title function
Are you showing me a way for Title to access this information? In this case
Info is the original snippet class? Is this a way to access Info.title
outside of the instance of Info?
What would be ideal, at least in a certain sense, is if there would be some
way for the Loc to access the snippet instance and/or modify the transformed
xml that it is about to serve.
The next best option would be for all the title snippets to pass their
calculated title through some "global" (object/module) method so that the
snippets would generate their specific title and have the title modified in
a global way too.
The simplest option is just to repeat the common title code everywhere.

Yeah we're aware of that. That is based on toString application which
is JDBC driver dependent. I think Derek started some work on this to
correct this behavior. Derek ?

[Lift] Db.addLogFunc
Hi,
I have the following in boot:
DB.addLogFunc((query, len) => Log.info("The query: "+query+" took
"+len+" milliseconds"))
I was expecting the query parameter to be sql, but it's actually some
sort of guid
"INFO - The query: 6839c016-0122-f09a-9c96-003844e8 took 5
milliseconds"
Any ideas?
I'm running with derby.
Thanks,
Jon

[Lift] Re: New features
In your use case it can only be Long and User. But there has to be a type
parameter because other people might have a String key and a Request mapper.
And the contents of ManyToMany have to be type safe to enforce their
consistency with however the user of ManyToMany wants them to use it.So I
think what you want is that the compiler should figure out that since you're
using it with a KeyedMapper[Long, User], which is ManyToMany's T <:
KeyedMapper[K,T], and ManyToMany extends KeyedMapper[K,T] and it has a self
type of T, and therefore it would be a compiler error to write anything
besides Long and User, therefore you must want to use Long and User and they
should be inferred.
I could certainly hear that, although I'm not much of a type theorist. So
feel free to open an enhancement ticket on Scala's Trac! :)
If I understood correctly...

[Lift] Re: New features
Naftoli,
As I said at the outset, this is really beyond my expertise. But I
think it's too
broad and maybe, even unnecessary. In my example, K can only be one
type,
Long, and T can only be of type User. Anything else, and the compiler
can't be
guaranteed to catch it, but try running the application and you get
things like
stack overflow errors.
How you would fix this is beyond me. All you can really do, at this
point, is
make sure to include these kinds of restrictions in the docs.
Glenn...

[Lift] Re: New features
It's too broad, or it's too restrictive/unnecessary? I'm confused, you seem
to imply both.If it's too broad, tell me why. But if you want to know why it
needs the type parameter, it's because it has to use the type parameter in
its implentation -- just count how many times its source code uses it! And
if you want to know why the compiler can't infer it or be told to infer
it... that's another issue.
But if passing a type that creates a conflicting inheritance causes a
compiler crash, that's not something I can help. :)

[Lift] Re: Alternate part of view
Here's some view xhtml:
>

Client
Client
And here's some snippet code:
> xhtml.bind("req",
"noClient" -> noClient _,
"client" -> hasClient _,
...
)
def noClient(xhtml: NodeSeq) = {
var clientQuery: String = ""
def queryClient {
...
}
client match {
case None =>
xhtml.bind("client",
"query" -> keepAttrs(SHtml.text(clientQuery, clientQuery = _)),
"set" -> SHtml.submit(?(">"), ()=>queryClient)
)
case Some(_) =>
NodeSeq.Empty
}
}
So both alternatives are always bound to a NodeSeq=>NodeSeq function, and
both functions have to check if client is None or a Some, and always one
function returns NodeSeq.Empty and the other one something useful.
So my question is not, "how can I do xxx," but, "is there a 'DRY'er or more
concise way to do it."
In another place I used a slightly different technique:
> val emptyFn = (ns: NodeSeq) => NodeSeq.Empty
def noLocationKind = (ns: NodeSeq) => ...
def hasLocationKind(kind: LocKind#Value) = (ns:NodeSeq) => ...
ns.bind("nlt",
//"name" -> {(ns:NodeSeq)=>Text("foo")},
"locKind" -> lkOpt.map(hasLocationKind).getOrElse(emptyFn),
"noLocKind" -> (if(lkOpt==None) noLocationKind else emptyFn)
).bind("nlt","name"->nlt.name.is)
Where lkOpt is the value that can be None or a Some. Instead of letting the
functions check None/Some, I check outside the function. But it still seems
that in theory it could be simplified.
chooseTemplate doesn't solve the problem that the alternative NodeSeq has to
be transformed to NodeSeq.Empty.
P.S. Notice that I'm using my implicit to call bind on the NodeSeq :)
P.P.S If you look closely, there's another problem that I had. For some
reason the first "name" -> ... was getting ignored, and it only worked in
the second bind.
Thanks!

[Lift] Re: New features
Naftoli,
At the risk of discussing something obviously beyond my pay grade,
isn't the real issue Scala traits
and the use of parameterized types. The ManyToMany trait is defined
as:
trait ManyToMany[K,T<:KeyedMapper[K, T]]
But this isn't really correct,is it, the parameter is too broad, and
that leads to a lot of the confusion and results in the need for
unnecessary documentation. When you think about it, why all the
duplication? Why do I need to
write my User entity as:
class User extends MegaProtoUser[User] with ManyToMany[Long,User]
when we all know that this would be much cleaner:
class User extends MegaProtoUser[User] with ManyToMany.
But traits aren't like interfaces. They have implementation and would
need to know something about
the parent class they are attached to - and how would you accomplish
that (reflection, maybe). This is
more a Scala issue than a Lift one, I think.

[Lift] SOAP web services?
I was reading through the Lift book PDF and it mentions only REST- style web services. In our case, we need to look at re-implementing a set of existing SOAP web services (is there anything like 'wsdl2scala' anywhere?). I would appreciate any best practices and suggestions for implementing SOAP web services in the context of a larger Lift app (and Scala in general). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] IE8 and single-field forms
Apparently if your form has only one text field (input tag w/
type=text) and one button tag, IE8 does not include the button as a
field in the post, but only includes the text field. Here's the IE8
bug report:
https://connect.microsoft.com/IE/feedback/ViewFeedback.aspx?FeedbackID=389736
The result is that my function that is bound to the button is not
called when processing the post. I've worked around it by adding
another input tag of type=text and style=display:none (hidden field
didn't fix it).
Anyway, just wanted to post a heads up and see if anybody else has
come across this.
The relevant code is below.
Template:
Confirm Email Address
First, we need to confirm your email address so we know it's
yours.
Email Address:
Snippet:
//note that my SForm.button is just the same as SHtml.submit but I use
a button instead of input w/ type=submit
def sendConfirmation(xhtml:NodeSeq) : NodeSeq = {
def doConfirm() : Any = {
if (email.is.length > 0) {
try {
MemberSystem.confirmEmailAddress(email.is)
notice("Your confirmation email will be sent in a few
moments.")
hideForms.set(true)
}
catch {
case MemberSystem.InvalidEmailAddressException(msg) =>
error("The email address you provided "+msg)
case MemberSystem.EmailAddressAlreadyInUseException =>
error("The email address you provided is already being
used by another member")
case _ =>
error("We were unable to send to this email address,
please try another")
}
}
else { error ("Email address is required") ; Empty}
}
if (!hideForms.is)
bind("signup", xhtml,
"email" -> FocusOnLoad(SForm.text(email.is, email(_))),
"submit" -> SForm.button("Send Confirmation", doConfirm))
else Nil
}

[Lift] Re: Title function
Putting it in an "object" won't work, since you probably want the title to
be done per-request. To clarify what I'm saying, here's a small example of
how I would set the title for an edit page:
First, the template:
Type stuff here:
Then the snippet class:
class Info {
object toEdit extends RequestVar[Box[InfoStuff]](Empty)
def title(ignore : NodeSeq) : NodeSeq = Text(toEdit map ("Edit " + _.name)
openOr "No item to edit!")
def edit (xhtml : NodeSeq) : NodeSeq = ...
}
This assumes that whatever page is redirecting to the edit page will set the
RequestVar, something like:
S.redirectTo("/edit", () => Info.toEdit(Full(someInfoStuffInstance)))
Does that make sense?
