[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:
lift:surround at=content
head
titlelift:Info.title //title
/head
lift:Info.edit form=POST
h1Type stuff here:/h1
edit:stuff /
input type=submit value=Save /
/lift:Info.edit
/lift:surround
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?

You mean the snippet should put its new/edit flag somewhere that the Title

because it can be set on every request, if Title is processed after the

would work.
Seems like it may be more work than the other way, though.
By the way I sent corrected message afterward--my question was not about
LocParams but of the items of type ParamType.

If you're just looking for a way to programmatically set the title, getting

Maybe my setup is atypical then :)
My default.html is does not have a title tag; instead each view has its
own, relying on head merge.
I don't know if originally I had it in default using lift:Menu.title or
not, but the difficulty with that would be that some pages can be used
to
edit or add a new item, and the title needs to reflect that.
Because the Title() case class takes a function, you can have it do all
forms of stuff including looking to the current user, whether you're
editing, and do the right thing.
So either (1) I need a way that the value of Menu.title will depend on
data
in various StatefulSnippets; or (2) make the title ambiguous (add/edit
neutral); or (3) leave the titles in the views and process them with a
function somehow; or (4) put a snippet in the title of every view to
get
the
user.

How does the Title LocParam work?
The Title case class has a function that converts the current object

represented by the Loc.
Is there a way to modify all titles to e.g. include the logged in
user's
name, without having to edit all the views?
The title tag is typically defined in the default template. You
could
include a snippet in the title tag that would contain the user's
name.
I
would see this as separate from the title of the specific page referred
to
by the Loc.Title.

[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:
lift:MemberSnippet.sendConfirmation form=POST
fieldset
legendConfirm Email Address/legend
pFirst, we need to confirm your email address so we know it's
yours./p
labelEmail Address:/labelbr/signup:email/br/
signup:submit/
/fieldset
/lift:MemberSnippet.sendConfirmation
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: 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.

The offending code seems to be the line: roles -
theUser.roles.flatMap{

Here's my User class:
class User extends MegaProtoUser[User] with ManyToMany[Long,User]{
def getSingleton = User // what's the meta server
object roles

Role)

this code, let alone just
trying to explain the problem so I can get help.

By the way, as per my correction, you can implement list the regular way
without ModelView, and just use ModelSnippet's load function in your edit
link or button, passing it the User instance.

Naftoli,
I fixed my code per your comments and now I can edit and remove users
from a list, as long as I populate the list with
ModelView instances, as you said. As for the docs, this step was not
clear to me at all. I just assumed that the list was
just populated with User entities and the view in the ModelSnippet was
instantiated with the selected User on each request.
It sounds like your plate is pretty full, so I won't expect much, but
sometime soon, could you provide an example, or improved
docs, for using TableEditor and its related ItemsList trait.
Thanks for all.

[Lift] Re: Alternate part of view
Here's some view xhtml:
req:noClient
label for=clientqueryClient /label
client:query id=clientquery size=5/
client:set /
/req:noClient
req:client
Client client:unset /
client:editclient:name //client:editbr /
client:details /
/req:client
hr /
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!

So does anyone have a better way of switching view parts?
If it's repeated, then lift:embed / the part that you need.
lift:MaybeClient
client:yeslift:embed what=/templates/client_edit.html//client:yes
client:nolift:embed what=/templates/client_chooser.html/client:no

[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: 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.

Putting it in an object won't work, since you probably want the title to

how I would set the title for an edit page:
First, the template:
lift:surround at=content
head
titlelift:Info.title //title
/head
lift:Info.edit form=POST
h1Type stuff here:/h1
edit:stuff /
input type=submit value=Save /
/lift:Info.edit
/lift:surround
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?

Because the Title() case class takes a function, you can have it do all
forms of stuff including looking to the current user, whether you're
editing, and do the right thing.
So either (1) I need a way that the value of Menu.title will depend on
data

neutral); or (3) leave the titles in the views and process them with a

[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). Here's how I've tried. Boot.scala // Build SiteMap val entries = Menu(Loc(Home, index::Nil, Home)) :: Nil LiftRules.setSiteMap(SiteMap(entries:_*)) default.html head ... titleLift:Menu.title//title ... /head body ... lift:Menu.builder li_item:class=active/ 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. What am I doing wrong here?

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
}
}

[Lift] Re: Eclipse setup
You have two output folders: the Scala IDE = 2.7.5.final only supports one. Use a single default output folder. That helped somehow, at least in the Boot.scala file it was pretty much ok. But the other files were no better. For instance, clicking on MetaProtoUser still opens Object.java source... You also have source directories nested below the top level of your project. Although I've seen reports that this works from various people, there's code in 2.7.5.final and earlier which makes this unlikely. If switching to a single output folder doesn't solve your problems try also moving your source directories to the top level. I tried to move the scala src folder src/main/scala to the project root, but that didn't improve things. 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. Is there any configuration (Eclipse version+plugin versions+project setup) that is known to work? Both of these issues are fixed on trunk (but don't go there unless you're using the Lift 2.8.0 branch). Unfortunately it didn't help to avoid these two issues... Let me know how you get on ... Well, I switched to idea for now, and i don't like it. Would it make sense to use the trunk version? Cheers, Steffen.

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?

Although I've seen reports that this works from various people, there's code in 2.7.5.final and earlier which makes this unlikely. If switching to a single output folder doesn't solve your problems try also moving your source directories to the top level. I tried to move the scala src folder src/main/scala to the project root, but that didn't improve things. 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. Is there any configuration (Eclipse version+plugin versions+project setup) that is known to work? Both of these issues are fixed on trunk (but don't go there unless you're using the Lift 2.8.0 branch). Unfortunately it didn't help to avoid these two issues... Let me know how you get on ... Well, I switched to idea for now, and i don't like it. Would it make sense to use the trunk version? Cheers, Steffen.

[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).

bind(lift, lift:content/,

content - XML.loadString(content.content)

[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 lift:foo/, the foo snippet will be invoked.

[Lift] Custom Login
I am new to Lift and have a newbie question. I have searched the group and have not really found an answer to my question. I was hoping for some pointers on implementing custom Login logic. I am currently looking at the MetaMegaProtoUser code and am trying sort out what I will need. I have no need for scaffolding, and am using an existing DB with client access through Hibernate/JPA classes. I can sort out the DB access, etc., I am just getting a bit overwhelmed trying to figure what bits I need to replicate from MetaMegaProtoUser, if any. I know it does quite a bit... Anyways, it is probably staring me right in the face... and I am just being dense... but any pointers would be appreciated! I am loving Scala and am really enjoying learning Lift, really cool work guys! Cheers! Jeff --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[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.

If I change the third argument, I get this as the title in my browser as well as the link in the site map.

Here's how I've tried. Boot.scala // Build SiteMap val entries = Menu(Loc(Home, index::Nil, Home)) :: Nil LiftRules.setSiteMap(SiteMap(entries:_*)) default.html head ... titleLift:Menu.title//title ... /head body ... lift:Menu.builder li_item:class=active/ 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. What am I doing wrong here?

[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: 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. If it breaks thing, please revert the changes. On Thu, Aug 6, 2009 at 9:55 AM, Naftoli Gugenheim naftoli...@gmail.comwrote: 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...

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... On Aug 6, 9:33 am, Naftoli Gugenheim naftoli...@gmail.com wrote: 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. :) Regards. On Thu, Aug 6, 2009 at 12:26 PM, glenn gl...@exmbly.com wrote: 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. Glenn... On Aug 5, 8:24 pm, Naftoli Gugenheim naftoli...@gmail.com wrote: Building causes a stack overflow? So the question is, is it the resident compiler or plain scalac also crashes? Or just the presentation compiler? What do you see in the error log view or file?
