[Lift] Template help
I need to create a snippet sequence that looks something like this: a href=next span class=namename/span span class=commentdescription/span span class=arrow/ /a The anchor needs to be generated using SHtml.link, and name description need to be bound. As a result, I end up with a template sequence like this: b1:link span class=nameb2:name//span span class=commentb2:description//span span class=arrow/ /b1:link Then, I need snippet code that does something like: bind(b1, xhtml, link - SHtml.link(S.contextPath, () = clicked(b), bind(b2, chooseTemplate(b1, link, xhtml), name - Text(b.name), description - Text(b.description) )) Yuk... I'm just not happy with this. Sure, I could make it a little more readable, but this still seems unnecessarily complex and verbose. I also really don't like how the view logic is dictating my binding logic. In other words, if I wanted to change my view organization, there is a high chance that I also need to change my binding logic -- and that just isn't right... Is there a better strategy? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] XmlResponse with cookies
Hi,
I need XmlResponse with cookies, but have gotten following error.
$ mvn scala:console
scala import _root_.net.liftweb.http._
import _root_.net.liftweb.http._
scala new XmlResponse(foo /){
| override def cookies = S.responseCookies
| }
console:8: error: type mismatch;
found : List[net.liftweb.http.provider.HTTPCookie]
required: object Nil
override def cookies = S.responseCookies
^
It will be nice, if XmlResonse#cookies is defined as follows,
case class XmlResponse(xml: Node) extends NodeResponse {
def docType = Empty
def code = 200
def headers = List(Content-Type - text/xml; charset=utf-8)
def cookies: List[HTTPCookie] = Nil// !!
def out = xml
}
If it is allowed, I'll commit it after the review process.
Sincerely,

[Lift] Re: XmlResponse with cookies
Wouldn't a more appropriate idiom be to use overloaded apply methods in a
companion object?
That is:
def apply(node: NodeSeq): XmlResponse
def apply(node: NodeSeq, cookies: List[HTTPCookie]): XmlResponse
Thoughts?
Cheers, Tim

[Lift] does AutoComplete work ?
Hi, does AutoComplete work ? I tried running the lift-example from snapshot on a local server, autocompletion isn't happening on the AJAX Samples page. The rest of the Ajax stuff works fine. AC does work on http://demo.liftweb.net/ajax though, so the problem doesn't seem to be browser-related. I also tried overriding autocomplete_? in a MappedEnum in 1.1-M7. I did get a text field instead of a combo, but no autocompletion. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: ManyToMany decision
On Tue, Nov 10, 2009 at 2:16 PM, Naftoli Gugenheim naftoli...@gmail.comwrote: Hello. When I wrote ManyToMany a couple of months ago, I designed it to internally hold a collection of join table records, and to act as a collection of elements of the child table. For example, given Volunteer and VolunteerGroup where volunteers can be in multiple groups, Volunteer.volunteerGroups implements a collection of VolunteerGroups, but internally it's actually managing a collection of VolunteerVolunteerGroups (the join table). I don't think you really need to maintain the pivot table list (VolunteerVolunteerGroups) at all. If you maintain the Many-to-Many as part of the object, and use a standard naming convention then you don't really need this extra list running around. You can still build the SQL correctly knowing only the objects involved. The current implementation throws an error (Predef.error) when it tries to get the child element via the join record and it doesn't exist. Thus any page accessing corrupted data will not display if the error is not caught. I plan, G-d willing, to change the implementation to silently skip such records. But the occurrence that reminded me of the defect also brought another point to my attention. To my knowledge Lift's schemifier does not correctly generate foreign key constraints for all databases (at least not at the point in time it schemified my H2 database... :) ) so we need a way for ManyToMany to keep things in sync. ManyToMany helps, to an extent, because when its MappedManyToMany members are initialized, it puts them in a list, and it propagates saves and deletes. So if you have a ManyToMany Mapper instance that contains a MappedManyToMany that has been initialized, and you call delete_! on the Mapper, it will delete all the associated join table entries. But it's not enough. 1. That can only happen if both sides of the relationship use MappedManyToMany. Is there some way to enforce this? I was thinking of using a combination of (a) requiring the foreign MetaMapper to extends ManyToMany, and (b) when a MappedManyToMany is initialized, it should check that the foreign MetaMapper/ManyToMany actually contains a MappedManyToMany referring to the current MappedManyToMany. (a) is not sufficient without (b), and (b) has the same problem as #2 below, that objects are lazy. I think you're right here. Both sides have to have the mapping.. however I don't think there is a good clean way to detect this without a compiler plugin of some kind. 1. There is a basic problem, which is that since objects are lazy, if you haven't referenced the MappedManyToMany field, delete_! will not be able to propagate to the join entries. As you traverse the deleteing side, doesn't the other side get initialized as well? #2 and #1.b can be solved by using reflection to initialize the MappedManyToMany members eagerly, just as MetaMapper does for all MappedFields. (MappedManyToMany is not a MappedField.) Now the advantage to having them lazy is that if you don't reference them they don't query the database. This advantage can be retained though by implementing the collection internally to populate lazily, much as MappedOneToMany already is. Thoughts? I think your maintaining to much information that can be deduced from the context.

You'll get:

- what happens if you have another test suite? I think you'd then hit
the same problem that I did, when the second test suite tries to fire

The example in ESME is a singleton, but the start method is actually a lazy
val, so you can call it from any test, but it will only be triggered once
per run per classloader. Does this give you what you want? If not, it'll
be some mucking around with multiple classloaders.

Yeah, but with this change: http://reviewboard.liftweb.net/r/95/
You'll get:

It looks like the JettyTestServer is a singleton inside the test suite
- what happens if you have another test suite? I think you'd then hit
the same problem that I did, when the second test suite tries to fire
up Jetty it will fail because Lift has already been initialized.
The example in ESME is a singleton, but the start method is actually a lazy
val, so you can call it from any test, but it will only be triggered once
per run per classloader. Does this give you what you want? If not, it'll
be some mucking around with multiple classloaders.

Presumably because it has already loaded and started Lift, and my
second unit test fires up Jetty again trying to start Lift again which
I take it is not supported.
So, I figure I should either:
a. refactor my tests so that I only create one jetty and lift instance
ever
- this will probably require 'resetting' the service somehow to ensure
a blank slate between each unit test, not sure how I get a hold of the
instance in question for that
b. somehow launch jetty/lift differently, or force lift to cleanup?

[Lift] Re: ManyToMany decision
To clarify: The fundamental purpose of ManyToMany, like OneToMany, is that rather than dealing with children of an entity as they are in the database at a given moment, instead, they should have similar semantics to a MappedField: You load it from the database, modify it to your hearts content, and then decide whether you want to save it or not. For example, calling set() on a MappedField does not write immediately to the database, and it's a good thing too--imagine a multi-page form where you can go back and forth to different screens, or a single page form that uses submit buttons that perform some action but you stay on the same page. You don't want the user's changes to go the database unless he clicks Save. So too, one often wants to edit a list on one screen. There should be submit buttons to add records, etc., but if you don't click save it shouldn't go to the database. So MappedOneToMany and MappedManyToMany act as collections, internally keeping track of which records were inserted or removed, but not performing a create or delete until the field is saved. So in other words they act as multi-valued fields. There are two ways MappedManyToMany can do this. It can hold a list of join table records, or child table records. Either way it will have to look up the other at times. Now in order for saves and deletes on the ManyToMany Mapper to be propagated to the MappedManyToMany fields, it has to have a list of them. The list only gets populated when code references the field, causing it to be initialized and add itself to the list of m-n fields. So we make all of these proposed changes? - Jim Barrowsjim.barr...@gmail.com wrote: On Tue, Nov 10, 2009 at 2:16 PM, Naftoli Gugenheim naftoli...@gmail.comwrote: Hello. When I wrote ManyToMany a couple of months ago, I designed it to internally hold a collection of join table records, and to act as a collection of elements of the child table. For example, given Volunteer and VolunteerGroup where volunteers can be in multiple groups, Volunteer.volunteerGroups implements a collection of VolunteerGroups, but internally it's actually managing a collection of VolunteerVolunteerGroups (the join table). I don't think you really need to maintain the pivot table list (VolunteerVolunteerGroups) at all. If you maintain the Many-to-Many as part of the object, and use a standard naming convention then you don't really need this extra list running around. You can still build the SQL correctly knowing only the objects involved. The current implementation throws an error (Predef.error) when it tries to get the child element via the join record and it doesn't exist. Thus any page accessing corrupted data will not display if the error is not caught. I plan, G-d willing, to change the implementation to silently skip such records. But the occurrence that reminded me of the defect also brought another point to my attention. To my knowledge Lift's schemifier does not correctly generate foreign key constraints for all databases (at least not at the point in time it schemified my H2 database... :) ) so we need a way for ManyToMany to keep things in sync. ManyToMany helps, to an extent, because when its MappedManyToMany members are initialized, it puts them in a list, and it propagates saves and deletes. So if you have a ManyToMany Mapper instance that contains a MappedManyToMany that has been initialized, and you call delete_! on the Mapper, it will delete all the associated join table entries. But it's not enough. 1. That can only happen if both sides of the relationship use MappedManyToMany. Is there some way to enforce this? I was thinking of using a combination of (a) requiring the foreign MetaMapper to extends ManyToMany, and (b) when a MappedManyToMany is initialized, it should check that the foreign MetaMapper/ManyToMany actually contains a MappedManyToMany referring to the current MappedManyToMany. (a) is not sufficient without (b), and (b) has the same problem as #2 below, that objects are lazy. I think you're right here. Both sides have to have the mapping.. however I don't think there is a good clean way to detect this without a compiler plugin of some kind. 1. There is a basic problem, which is that since objects are lazy, if you haven't referenced the MappedManyToMany field, delete_! will not be able to propagate to the join entries. As you traverse the deleteing side, doesn't the other side get initialized as well? #2 and #1.b can be solved by using reflection to initialize the MappedManyToMany members eagerly, just as MetaMapper does for all MappedFields. (MappedManyToMany is not a MappedField.) Now the advantage to having them lazy is that if you don't reference them they don't query the database. This advantage can be retained though by implementing the collection internally to populate lazily, much as

[Lift] Re: Template help
I didn't see Tim's blog post, but another option is to bind in two passes. First bind the outer level: b1:link should become an SHtml.link, preserving the same set of child elements. So here use a NodeSeq function: kids = SHtml.link(..., kids). Then pass the resulting NodeSeq to a bind invocation that transforms your other elements. You can place this in one statement, by using one call to bind as the NodeSeq argument to the other call. And you can use the implicit in BindPlus to chain bind calls: xhtml.bind(prefix, bindParams ... ).bind(pre2, ...) That said, I think there is a fundamental, inevitable tension between separation of view and logic, and repetition (not really your point). I tried to address this, as it applies to Mapper fields, to a small extent in ModelView.

[Lift] Minor Bug? MappedString.valUnique should return one FieldError
Hi, I'm currently adding a uniqueness requirement to a field, but there are duplicate entries (for empty string) in my database already. Currently valUnique maps each match it found to a FieldError, but should probably return one FieldError regardless of how many matches it finds. - Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] New Milestone coming soon
Folks, There are two critical issues with M7: - Issue 164 http://github.com/dpp/liftweb/issues#issue/164 JSON/Ajax messages do not carry Notices back to the client. - The Session manager is not initialized properly. Basically, this means that sessions will be expired by the web container, but not by Lift and GUIDs that map to functions on the server side are not removed until the session is terminated. We're planning to do an M7.1 release later this week (probably Friday). If there are other *critical* defects (stuff that means you can't use M7 in production), please speak now.

[Lift] How to use Box
Wondering what's the normal practice of using a Box. As a Java
developer, I always want to get the boxed value by a method named
Value like
val optionalContent = Full(This is optional)
Log.info( The optional content is + optionalContent.value)
But I know its not a valid way to do so in lift ( same for Option in
Scala)
From the book programming in Scala , there's an example
val withDefault: Option[Int] = Int = {
case Some(x) = x
case None = 0
}
which suggest the use of match to retrieve the value of the boxed
content. It make sense to me and I'm totally agree with the advantage
of using match + option (Box) combination.
However, as a newbie to Scala, I'm so tempted to use something
like .Value to retrieve the box value .
So, what's the normal way to use Box ?? Could someone kindly provide
some example on how to use ? I tried to look through some source code
of Lift but its not easy for a newbie :)
Thanks

[Lift] Re: New Milestone coming soon
OracleDriver doesn't work with CRUDify when attempting to view a list of entries, it gets an SQL error due to use of LIMIT/OFFSET, which Oracle does not support. Defining brokenLimit_? = true in OracleDriver makes it work for me. I can do this myself by including my own copy of Driver.scala, so I don't know if it counts as critical, but it seems like a pretty localized (and thus low-risk) change. -- Jim On Wed, Nov 11, 2009 at 11:54:46AM -0800, David Pollak wrote: Date: Wed, 11 Nov 2009 11:54:46 -0800 From: David Pollak feeder.of.the.be...@gmail.com To: liftweb liftweb@googlegroups.com Subject: [Lift] New Milestone coming soon Folks, There are two critical issues with M7: * Issue 164Â http://github.com/dpp/liftweb/issues#issue/164 Â JSON/Ajax messages do not carry Notices back to the client. * The Session manager is not initialized properly.

[Lift] Re: CometActor and render
one more thing: I also ran the code without the piece that retrieves
web pages and gets their length. Instead I just had the Calculator
class sleep for 10 seconds (which is longer than the http request
takes) and then return a random number. This worked fine. I can't see
what the difference is.
On Nov 11, 11:26 pm, Jack Widman jack.wid...@gmail.com wrote:
David,
I have attached my code. It runs but does not behave as I intended it to.
The code does a web search on the term scala and displays a list of URLs
of the results. Next to each URL it says Page Length : -1. A process is
running in the background which takes each URL, goes out and gets the page
and takes the length of the page. The length of that page is then supposed
to immediately appear on the page next to that URL. I put the lengths on a
queue, as they come in, and I have the Comet page poll the queue and display
the results. It would probably be better to have the results send a message
to the Comet class so the page is only re-rendered when there is a change
but for now I am polling.
I can see the lengths coming in and being put on the queue, but the Comet
page is not getting them till they are all retrieved. (This takes way too
long and nothing changes on the screen till its too late). I need them to
appear as they come in. Occasionally I can see a length being retrieved and
the Comet page finds it but even then it is not displayed until all the
lengths are in. I know this is not very clear but I think it will be clear
from the code.
I also know there are a lot of places in the code which can be improved and
I welcome all of your input but what I would love is to have these numbers
appear on the page as they they are retrieved. I have been stumped by this
for a while and I suspect that somebody who knows Lift well might see the
problem right away.
The class that retrieves the page lengths is called Calculator and the queue
is called SourceQueue. The classes are pretty small so hopefully it will be
clear what is going on. I want you to know I think it is incredible how
responsive you and the group are and I look forward to using Lift in the
future.
Thanks so much.

Jack,
I reproduced your code and it seems to work fine. I've enclosed a
working copy.
Some comments about your code:
- The foos variable and the foo variable may be getting confused in
the code... the render method may be rendering the same thing based on
the
unchanging foos variable.
- Doing null testing is a sign that you have logic errors in your
code. I strongly recommend using either Box or Option for everything
that
can logically not contain a value/reference. If you're bridging out
to Java
code and are expecting null from the Java code, write a small bridge
that
will wrapper the Java return values in Box/Option.
- You have a case class (Tick) that contains no parameters. Please
use a case object instead.
- Your Tick look is a spin loop. You fire a Tick message as part of
processing the Tick message. I would suggest that if you're polling,
that
you have a reasonable poll interval, otherwise you'll starve your CPU.
Further, having reRender on each loop through means that you're
forcing a
lot of bytes over the wire rather than only doing a reRender on changed
values.
Thanks,
David
