[Lift] Comet logger initialized too early?
Hi,
In trying to move to slf4j/logback I encountered an error when I removed
log4j from the cp:

I would seem that the Comet logger is initialised before lift is booted
(and thus using the default log config):
from LiftRules:
var cometLogger: LiftLogger = {
val ret = LogBoot.loggerByName(comet_trace)
ret.level = LiftLogLevels.Off
ret
}
Shouldn't this initialization be moved to after lift is booted?

[Lift] Mapper: Is it possible to avoid the n+1 selects?
Hi I have a mapped object A with a foreign key to mapped object B. I need to display the information (A+B) in a table. The not so smart way is to first query on the As and then for each A, get the B. This results in n+1 selects. Is it possible to ask Mapper, when querying for the As, that it should join with Bs table to fetch the B at the same time (ie the equivalent of join fetching in Hibernate)? /Jeppe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

The JDBC URL that we use for pocketchange makes an embedded server (no external connections, AFAIK).

[Lift] 1.0.1 release plan, forward porting changes
Hi, I have some code checked in on the 1.0_maint branch to fix the issues with PostgreSQL doubles and Oracle autoincrement primary keys (issue #37). If no one else has anything that needs to go into 1.0.1, I'll move ahead with releasing 1.0.1 and setting 1.0_maint to 1.0.2-SNAPSHOT. Also, does anyone have objections to forward-porting the changes I made to get PostgreSQL and Oracle squared away? The changes are primarily to DriverTypes, with some minor mods to Schemifier and MetaMapper to accomodate some new driver methods. You can see the changes here: PostgreSQL: http://github.com/dpp/liftweb/commit/54e6f64675d163a4fd7ba1ce0f14da8e4dc94aa2 Oracle: http://github.com/dpp/liftweb/commit/eda5e86092fec035b3f6326e05ba75fa1396b4bc Derek --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] how to do basic joins
I have 3 classes like so
class Foo extends LongKeyedMapper[Foo] with IdPK
def getBazes = {
Baz.findAll(...)
}
}
class Bar extends LongKeyedMapper[Bar] with IdPK
object fooid extends MappedLongForeignKey(this, Foo)
}
class Baz extends LongKeyedMapper[Baz] with IdPK
object barid extends MappedLongForeignKey(this, Bar)
}
How do I write Baz.findAll(...) so it will give me all the Bazes that
point to any Bars that point to the Foo. In SQL I would write
something like this:
SELECT * FROM bazzes WHERE bazzes.barid = bars.id AND bars.fooid =
111; (where 111 is foo.id)
I feel like I should be using ByRef here? But it's not clear to me
how to do it.

One possibility is to do Baz.findAllBy{PreparedStatement,InsecureSql}
(section 6.3.2 of lift book)
I am also curious if there is a safe way to construct a join.

Marius,
The original design goals of WSDL were very straightforward:
- a Port Type is a set of Message Types governing all the messages
arriving on the Port
- A Message Type is given precisely by an XML Schema (e.g. an XSD)
- A Port is instanced by binding a Port Type to an Endpoint (URL)
supporting a transport protocol
In symbols, WSDL was intended to be able to make statements of the form
- URL+Transport : { XMLSchema1, ..., XMLSchemaN }
- Notice the close correlation between this and the statement you see
on the Scala REPL all the time:
- ScalaExpr ret
- res1 : ScalaType
URL is the location of the resource/instance in the same way that res1
provides a location that the Scala REPL can use to look up the instance.
PortType is very much like a ScalaType. In the case of typing at the Scala
REPL from a command shell there is no question of transport and any
encoding/decoding necessary. However, if one had a more remote network
access to the Scala REPL that did involve some issues around transport and
encoding/decoding, then these two cases would be isomorphic.
BTW, this lines up nearly perfectly with the idea of sorts and sorting in
Milner's π-calculus.
Because message exchange usually involves parameter-passing because of
confusion about the role of Object Technology in all this, WSDL was
extended with the notion of Operation. This could have been done more
cleanly, but was not. Not everyone involved in WSDL's design had the same
picture in their minds of what they were attempting to accomplish.
As for what happens today, i could easily imaging WSDL and/or WSDL+SOAP
over RabbitMQ, for example. i think something like this is considerably
better than JSON over transport. The basic reason for this is
straightforward. XMLSchema are a form of typing discipline. So, you get a
typing discipline for messaging-style applications that fits well with the
typing discipline of a language like Scala.
This could, for example, play out very nicely in an actor framework. An
actor's mailbox is a good thing to locate at an URL. Then you have
statements of the form
- URL + Transport/Actor : { MessageType1, ..., MessageTypeN }
Today, Scala actors do not even support statements of this basic form,
though they would greatly enhance the actor package.
Beyond this, you can imagine putting constraints on the order of messages.
Here's a general scheme
- Actor : ( { MsgType1 - Type1, ..., MsgTypeN - TypeN },
RegularExpressionOver(MsgType1,...,MsgTypeN) )
- The first element in the pair just maps message type names to Scala
types (or the types of some host language) and the second element in the
pair says the order you expect to see messages in the mailbox.
- Here's an example: ( { Init - OpenSession( id, pwd ), Read -
ReadDb( ... ), Update - UpdateDB( ... ), Finish - CloseSession( ... ) },
Init.(Read+Update)*.Finish )
- It says that the only legal sequences of messages in the mbox are
of the form Init :: Read-or-Update :: ... :: Read-or-Update :: FInish.

[Lift] Welcome Joni Freeman to the Lift committers
From Joni: Thanks everyone, it is great to be part of growing Lift community! Here's a short description of current state of lift-json module (I haven't pushed it to master yet, it currently lives in my fork at http://github.com/jonifreeman/liftweb/tree/master Will push to master real soon.). The module provides: * Fast JSON parser Much faster than scala.util.parsing.json.JSON parser, bit slower than fastest known Java JSON parser: http://github.com/jonifreeman/liftweb/blob/e2e59b63a427258e7dde9b0877691322c29c8552/lift-json/benchmark/README.md * XPath like queries Examples: http://github.com/jonifreeman/liftweb/tree/e2e59b63a427258e7dde9b0877691322c29c8552/lift-json * Extractors (experimental) Case classes can be used to extract values from JSON. Examples: http://github.com/jonifreeman/liftweb/blob/28dbf1a221df97f27bd788ae57c005407547d480/lift-json/src/test/scala/net/liftweb/json/ExtractionExamples.scala * DSL to produce valid JSON Examples: http://github.com/jonifreeman/liftweb/tree/e2e59b63a427258e7dde9b0877691322c29c8552/lift-json * Pretty and compact printing Uses similar system as Philip Wadler described: http://homepages.inf.ed.ac.uk/wadler/papers/prettier/prettier.pdf If you have time please review, hack and play with this. Now is a great time to tweak the APIs since this is not published yet.

[Lift] Dynamic URL creation
Hello there,
I'm stumped! I've got snippet code that is like this:
val nextpage: String = ... calculate next page number ...
bind(c, xhtml,
next - a href=/customer/page-{nextpage}next/a,
back - back
)
But when the page is generated, the link is /customer/page-
{nextpage}, not /customer/page-2, /customer/page-3, etc.
How do I get the nextpage value in my link? My template is just
c:backc:next with the surrounding tags.

[Lift] Symlinks and Javascript Files
My Lift project is in a git repository and to the repository I've
added a submodule. Since right now I only want one javascript file
from this submodule, my thought was to make the directory src/main/
webroot/js and then make a symbolic link to the javascript file in
question. Unfortunately, when I try to request the file at
http://localhost:9090/js/jquery.sparkline.js, I get a 403 response
that says the page is not defined in my sitemap. There was no note of
the request in the stdout.
Thinking that the js subdirectory is the problem, I then tried making
the symlink in the webroot directory and got a 404 error. On stdout it
said:
2009-08-13 18:38:23.051::WARN: Aliased resource: file:/Users/peter/
Sites/Equal%20Networks/server/src/main/webapp/
jquery.sparkline.js==file:/Users/peter/Sites/Equal%20Networks/server/
vendors/dashboard/www/jquery.sparkline.js
From this I gather than Lift is troubled by the presence of a symlink
and refused to acknowledge its presence. Is this true? If so, why?
From the thread last week on ExtJS I see a discussion on loading files
in webroot, including supporting a css directory by adding the
following to Boot.scala:
ResourceServer.allow {
case css :: _ = true
}
I already have a css file being served from a directory in the exact
same location without any additions to Boot.scala. Nonetheless, I
tried the following:
ResourceServer.allow {
case js :: _ = true
}
Unfortunately, this had no effect. So, how can I get my symlinked
javascript to be server? Or should I just give up on symlinks
altogether (I'm not a git master, so perhaps that was the wrong
approach anyway).
