All of the MetaMapper's find methods have corresponding findDBxxx
methods which accept a ConnectionIdentifier parameter.

class MyUser extends Mapper[MyUser] {
  object name extends MappedString(this)
  override def dbCalculateConnectionIdentifier = {
 case me => me.name.is match {
 case n if n.charAt(0) < 'n' => dbAtoMConn
  case _ => dbNtoZConn
 }
  }

Is how the shard should be selected.

[Lift] Snapshot documentation not current any more

[Joachim A.]

Hi,
I use the generated API documentation almost every day - thanks a lot for 
that!

The documentation (http://scala-tools.org/mvnsites-snapshots/liftweb/lift-
webkit/scaladocs/index.html) used to be updated from trunk (I think :). The 
current pages are not current, newly added things like SHtml.autocomplet and 
the  Join/Prefect are missing. 

Would be great to have documentation updated from trunk again :)

Regards,
Joachim

[Lift] Re: Confirming guesses on Mapper

[Derek Chen-Becker]

Sorry, I forgot to mention that this would have to hook into the QueryParams
code as well. I don't know if it could be made type safe in the sense that
omitting the shard field in the params would throw a compile error, but at
least the selection would be uniform.

[Lift] Re: Confirming guesses on Mapper

[Derek Chen-Becker]

OK, I see them now. I'm writing up a little section on sharding and these
methods feel like they're not quite what I would want to use. Specifically,
they're using different criteria for insert and retrieval, which makes it
seem like things would get lost.  In the example posting I referenced
earlier, you use the first character of the email address for insert but
then the primary key for retrieval. It seems like you would want to use the
email address for retrieval as well. Is there some magic going on in the
code that I'm missing? If not, then perhaps we need to morph this into a
trait on the field and use a MetaMapper def that points to that field as the
connection arbiter. Maybe something like:

trait ShardSelector[T, O <: Mapper[O]] extends MappedField[T,O] {
  def selectConnection : PartialFunction[T,ConnectionIdentifier]

  def connection = selectConnection(this.is)
}

And in Mapper:

val shardField : Can[ShardSelector] = Empty

Along with some appropriate hooks into the current code.

Then you could do

class MyUser extends Mapper[MyUser] {
  object name extends MappedString(this) with ShardSelector {
def selectConnection  = {
  case n if n.charAt(0) < 'n' => dbAtoMConn
  case _ => dbNtoZConn
}
  }

  override val shardField = Full(name)
}

Thoughts?

 This allows you to compare two columns in the same row.  Because mapper
 does not allow for explicit joins or queries against more than one table at
 once (with the exception of the In construct), there's no "old style join"
 stuff.

 I've also changed the Join() QueryParam to PreCache... which is more
 descriptive of what it does.

OK, one last question for today before I start hacking at the text: You
mention some methods here for multiple databases with a single entity:

http://groups.google.com/group/liftweb/msg/76c965c189a85103?pli=1

But looking in the code I can't find those methods. Are they essentially
gone now? You also mentioned something better than sharding but I haven't
seen anything on the list (maybe I missed it).

[Lift] Re: lift-testkit/REST API test example code

[Dano]

Hi Tyler,

Thanks for your response.

The closest code to what I am looking for is under the sites/example/
src/test area.  Under this area, the WikiUsages.scala code is a nice
example of how to test a web page.  It uses a jwebunit WebTester class
to browse the page and perform tests on it.

Since I have a REST API, I am looking for a way to do http operations
where I can specify URL params and test what is returned. WebTester
does not fit this use.  However, I just need to find a class to
replace WebTester in the WikiUsages.scala code and I should be good to
go.

You have given me a good start and I'll keep searching.

Thanks.

This allows you to compare two columns in the same row.  Because mapper does
not allow for explicit joins or queries against more than one table at once
(with the exception of the In construct), there's no "old style join" stuff.

I've also changed the Join() QueryParam to PreCache... which is more
descriptive of what it does.

Dan,

In the Buy a Feature SVN repository, look in the stress_test directory.
It's got code that uses the testkit.

Thanks,

The issue is that TemplatePF does its lookup based on a Req... the request.
This makes sense because you may want to look things up based on an incoming
request including the path, the postfix, etc.  On the other hand,
findTemplate is called with a path... a List[String] because it's no longer
part of the Req, but being called by something beyond the Req.  I tried to
unify the two constructs about a month ago and found use cases in my code
for both constructs... thus they are both in Lift and serve their own
purpose.

Any particular reason not to? ... seems like it is at least as
appropriate as LiftRules.viewDispatch.It would boil down to
findAnyTemplate logic isn't it? .. but then again is there some sort
of redundancy between templates Pf and viewDispatch ? .. which would

[Lift] Re: lift-testkit/REST API test example code

[TylerWeir]

Hey Dano,

For getting examples of how to write tests, the main tree has a bunch
of tests in it:
http://github.com/dpp/liftweb/tree/master/lift/src/test
and
http://github.com/dpp/liftweb/tree/master/sites/example/src/test/

Poke around and you'll see that most of the tests are Specs
+Scalacheck.

Answer your question?

Joachim,

I've put code into 0.10-SNAPSHOT that will emit JNDI get/release (close)
debug information if you've got your log level set to debug.

Please run the code and see what's happening.  Alternatively, if you could
put together a simple example of the problem so that I can reproduce it
locally, I'll give it a try.

Thanks,

David

However, findVisibleTemplate is not called by the mechanism that looks up
the surround template. :-(

All Lift views are looked up via the LiftRule.viewDispatch.  You can put a
partial function via LiftRules.appendViewDispatch to match your template.
Lift will expect a LiftView which is a trait that can do the RDBMS lookup.

[Lift] Re: How does lift wrap the templates

[Marius]

Unless I'm missing something LiftRules.addTemplateBefore should
suffice. Lift (see findVisibleTemplate which is called before
processSurroundAndInclude) will look for your template so your Pf can
return it virtually from anywhere.

[Lift] Re: How does lift wrap the templates

[Derek Chen-Becker]

Ahh. What would make this really simple is if LiftRules.finder was a PF
instead of a straight def, since LiftRules.finder is what actually tries to
locate the template using ClassLoader.getResourceAsStream currently. In the
meantime, you might have luck with LiftRules.liftTagProcessing. You can
define your own PF that handles surround specially. In particular, I'd look
at processSurroundElement (and the related findAndMerge and processBind) in
LiftSession.scala.

[Lift] Re: How does lift wrap the templates

[Tim Perrett]

I am indeed talking about lift:surround :)

I see processSurroundAndInclude and what it does, but what i really
want to do it set the content of the surround dynamically (from a
layout i'll store in the DB)

How would one go about doing this?

Cheers

Tim

[Lift] Re: How does lift wrap the templates

[Derek Chen-Becker]

Are you talking about  tags? Those are handled in
LiftSession.processSurroundAndInclude, line 697. Here's some example code
for a utility method from an old app that uses it in some DispatchPFs I was
running:

  def process (xhtml : NodeSeq) : XmlResponse = {
val data = {xhtml}
XmlResponse({
S.session.open_!.processSurroundAndInclude(S.uri,data)})
  }

[Lift] How does lift wrap the templates

[Tim Perrett]

Hey guys,

Within lift, I cant seem to find where the content returned from
whatever template mech then gets bound to the layout content?

Can someone point me in the right direction?

[Lift] lift-testkit/REST API test example code

[Dano]

Hello Fellow Lifters!

I am working on a set of REST APIs for a new Innovation Game and was
browsing around the lift group for advice on how this is done.

>From one of dpp's posts, I gathered that lift-testkit is what I should
use.  Has anyone used lift-testkit to test REST api's or know of any
sample test code which could be used as a starting point?

Thanks very much in advance for any help.

[Lift] Confirming guesses on Mapper

[Derek Chen-Becker]

I'm mostly done with the rough draft of our Record/Mapper chapter and I
wanted to clarify a few points to make sure that my reading of the docs and
code is accurate:

   1. ByRef appears to me to essentially be an old-style join (using the
   where clause instead of join syntax). Is that accurate? Are there other use
   cases?
   2. It looks like the only way to get distinct results would be to use the
   findAllByPreparedStatement or findAllByInsecureSql methods. Is there some
   other way to do this that I'm missing?
   3. The toForm method in Mapper has an overload that takes a redoSnippet.
   What is the use case for this? Will it be supported in Record or has that
   functionality been folded into something else?
   4. It appears that the functionality of the buildSet... methods in
   MappedField has effectievly been replaced by the setFromAny in Field. Is
   this the case, or will those buildSet functions show back up in some
   subclass of field (it seems like there was a lot of overlap there)
   5. Am I reading correctly that Record no longer retains the orginal value
   of a field when it's changed, but rather just flags the field as dirty?
   (there are no is/was methods on Field)

These last two make sense to me since it seems like duplicated effort for #4
and not much of a use case on #5 that I can think of. Any info or comments
would be appreciated!

Thanks,

Derek

[Lift] Re: Mapper's BySql not "validated"?

[Derek Chen-Becker]

Another follow up on the SQL validation; OrderBySql needs the audit as well.
As a test, the following SQL fragment works in PostgreSQL:

val stmt = conn.createStatement()
stmt.executeQuery("select * from members order by userid; create table dummy
(id serial primary key);")

It throws an exception about multiple results being returned, but it still
creates the table.

[Lift] Re: noob question: working with scala 2.7.2

[Josh Suereth]

Here's your issue:

[INFO] Archetype repository missing. Using the one from
[net.liftweb:lift-archetype-blank:RELEASE ->
http://scala-tools.org/repo-releases] found in catalog internal


It's not pulling from the snapshot repository.

Try using archetype:create instead of archetype:generate.   (The generate
goal is from the new alpha of the archetype plugin and I don't htink it uses
the -DremoteRepositories property).

It is 2.7.1.

These are the the choices I made (interactively):

 Choose archetype:
1: http://scala-tools.org/ -> scala-archetype-simple (A simple scala
project)
2: http://scala-tools.org/ -> lift-archetype-blank (A blank/empty liftweb
project)
3: http://scala-tools.org/ -> lift-archetype-basic (A basic liftweb project
(with DB, css, ...))

It's the correct server.

Could you retry (the command from the initial mail) with "-e" argument
at end (to print error + stackstrace) ?

Pinging scala-tools.org works no worries for me. It does appear that
liberty.harpoon.me points to that server as well. No biggy tho, 2 domains
pointing to the same server that is.

Regarding my previous note with the maven command, can you check the pom.xml
of the generated project and tell us if  is 2.7.1 or 2.7.2 ?

Thanks

Do you guys get the same? I am sorry if this is getting off-topic for Lift,

Btw, I don't have any proxies of any sort.

I don't know what is the exact pbs (can't reproduce with the cmdline

The scala-tools.org has migrate IP last week which ip do you have ?
Do you use a proxy or a maven repository proxy ?

[Lift] DB connection not closed?

[Joachim A.]

Hi,
I have a lift application running in a tomcat container (using 0.10-SNAPSHOT) 
using a MySQL database. Tomcat is setup to provide connections via JNDI.

It runs very well. But now it has happened twice that the connection to MySQL 
fails. In the log appears a section which says that the connection to the 
database was never released.
I guess this is not normal for Lift :)  I assumed that DB.use() takes care of 
that.

What am I doing wrong with the DB handling? How can I make sure that the 
connections get closed?


I attached the relevant part with the stacktrace. 
bootstrap.liftweb.TransactionalWrapper is a wrapper to enable transactions 
with the DB, it has been given to my by David P. on this list (the code same 
as DB.buildLoanWrapper, I think).

Thanks a lot for you help,
Joachim

[Lift] Re: a plea for documentation

[philip]

Hi,

Actually my mind keeps flipping between SEAM and Liftweb, for months.

Today my feeling is I should focus on the JPA for my project in Java
using seam generate, then to take the JPA across to the Liftweb
environment and to program my website in Liftweb. Since my database is
big, nearly 100 tables in mysql. Of course torn between doing it
completely in SEAM or using JPA/Liftweb.

The great thing about Liftweb is the community is going good now - and
I guess my quesitons will get answered, also I would tend to
contribute back to the community. As opposed to completely doing it in
SEAM, sure there's documentation, but I wouldn't be contributing back.
Also I like Scala and I like where Liftweb is going.

Anyway, just thoughts, Philip

Ah, thanks for the info.

What else can I try?

I am using Fedora 9, with scala 2.7.2, openjdk, maven 2.0.9.

Btw, I have been using lift + maven + scala 2.7.1 for quite some time
without any problems.

This sort-of worked. It did create the project, but invoking "mvn jetty:run"
has started  a download of scala 2.7.1 (among other 2.7.1 related stuff)

I have a hunch it is not going to work.

maven could store SNAPSHOT in two way (configuration of the project):
* one jar SNAPSHOT
* several jar SNAPSHOT replace by timestamp, in this case maven use
metadata to find the right one

[Lift] Re: noob question: working with scala 2.7.2

[Tim Perrett]

Guys,

Personally, I wouldnt bother with those long commands, I find there
impossible to remember! Try:

mvn archetype:generate -DarchetypeCatalog=http://scala-tools.org/

This will present you with an interactive shell - just answer the
questions and it will create a skeleton project for you.

You will also benefit from reading this:

Cheers

Tim

[Lift] Re: noob question: working with scala 2.7.2

[Harshad RJ]

That's strange!

I did see those tips on blowing away ~/.m2, and in fact, I had started with
a clean Fedora install.

For extra measure, I tried removing ~/.m2 now, and I still get the same
error...

One thing I notice is that, at this location:
http://scala-tools.org/repo-snapshots/net/liftweb/lift-archetype-blank/0.10-SNAPSHOT/

... I cann't see any
lift-archetype-blank-0.10-SNAPSHOT.jar

which is the file maven is looking for.

There are a couple of similarly named files such as
lift-archetype-blank-0.10-20081124.173443-167-sources.jar

Is that how it is supposed to be?
