Re: [Lift] Mapper <-> JObject bridge

[Xuefeng Wu]

Hi,
I add two method to en/decode JObject/String

def encodeAsJsonString(in: A): String =
Printer.compact(JsonAST.render(encodeAsJson(in)))
def buildFromJsonString(json: String): A =
buildFromJson(JsonParser.parse(json).asInstanceOf[JsonAST.JObject])

Do there have better way?

[Lift] load testing a lift application

[jack]

I need to load test my site. It uses Comet. I am trying JMeter but I'm
not sure if it will work with Comet. The application I am testing is
basically a search engine that returns results via Comet.
What is a good tool to load and stress test this?

[Lift] Re: Documentation

I also suggest possibly looking at http://www.scala-lang.org/node/104
and http://www.naildrivin5.com/scalatour might help a bit.

Also working on the tuts at http://www.simplyscala.com/ are nice as
you can see them in action.

I would use MySQL for a production site.

If IdPK isn't doing what you want, then don't use it, just declare the
primary key field manually.

I compiled much of this thread into

we continue to discuss the naming goals and guidelines and vote or decide on
controversial goals, that wiki page should become more consolidated and less

[Lift] Re: partialUpdate and bind

[Peter Robinett]

Thanks, David. In my case I want to update a Flot graph and some text
boxes with new information. Since they have their source data in
common, it seems to me it would be most efficient to update the two
parts of the page simultaneously via a partialUpdate. Is this
reasonable or am I abusing partialUpdate?

[Lift] Duplicate Keys Created by Schemefier

[Peter Robinett]

My tables created by Schemefier have multiple keys for the primary key
when my Mapper model is declared like so: class myModel extends
LongKeyedMapper[myModel] with IdPK. There is naturally the primary key
but there is also a unique key on the column that simply duplicates
the functionality of the primary key.

Are other people seeing this? I've only looked on MySQL. This seems to
be because IdPK adds an id of type MappedLongIndex. Only the
longIndexColumnType of MySqlDriver has "UNIQUE KEY" in its definition.
Unique keys are great but, as I mentioned, if the column is also the
primary key the index is a duplication. Maybe this is something that
IdPK can disable when declaring the column? At least with MySQL
primary keys are guaranteed to be unique and InnoDB tables, which
Mapper uses, can have issues with long primary keys[1].

Should this be fixed? Or is the more helpful answer 'Don't use
MySQL'? ;-)

Re: [Lift] partialUpdate and bind

[David Pollak]

You can use PartialUpdate and bind() if you are doing a
SetHtml("id_of_thing_to_update", bind(...))

PartialUpdate is meant to update a subset of your HTML or some JavaScript
data structures.

[Lift] partialUpdate and bind

[Peter Robinett]

It's not clear to me whether I can use bind with partialUpdate in a
CometActor. I believe I can but bind returns a NodeSeq, while
partialUpdate takes a JsCmd. There is an implicit called
xmlToXmlOrJsCmd but it returns a RenderOut and I don't know of
anything that converts that to a JsCmd.

I'm using a partialUpdate because I have some other JsCmds that need
to be called that way and I just want to add an update to an xhtml
field to the set of commands.

Does that make sense?

Then I guess you could use an older version of Netbeans, or the 2.8 branch 
despite its work-in-progress status (use git and build yourself).

Re: [Lift] Re: Documentation

And from there, my suggestion would be to experiment with existing sample
Lift applications such as those in http://github.com/dpp/lift-samples to get
the "feel" for Lift from working code.

My suggestion is to get Programming in Scala, it explains the basics

for existing programmers. I also am learning not being a coder for

[Lift] Re: [lift] Documentation

I'd start with the Beginning Scala book and work on some code kata like
project euler. Lift is a jump in the deep end - I don't think knowing Java

Re: [Lift] [ANN] Lift 1.1-M8

[Jim McBeath]

It looks like the source jars are missing from the M8 repository, at
least for some of the libraries (for example,
).

Are these perhaps located somewhere else now?  Or do they typically
get added a bit later?

Re: [Lift] Help with exception deploying Hello World on GlassFish

[Timothy Perrett]

That version of lift uses 2.7.5 scala - they are binary incompatible with 
2.7.6. Moreover, that isn't enough dependencies for Lift - your probably 
missing a bunch of things. How big is the WAR? 

Cheers, Tim

Never, ever, ever for any reason use Scala 2.7.6.  It's very broken.

Lift 1.0.2 uses Scala 2.7.5 and only works with code compiled by the 2.7.5
compiler and with the 2.7.5 JAR files.

I would strongly recommend using Ivy to do dependency management.

Looks like you have a mess of wrong JAR files.

What version of Lift are you using?

[Lift] Help with exception deploying Hello World on GlassFish

[Donald McLean]

Following the layout for building a Lift application using Ant, I put
together a Hello, World application and deployed it. Deploying gives
an error (see below). Any suggestions on what the problem is and how
to fix it?

Thank you,

Donald

[Lift] Re: Caching Comet Actors

[Java1Guy]

Yes - it seems upon closer examination with jVisualVM that in fact the
CometActors *are* reused for each page.  Yet again, Lift Rules!  (I
had been looking at printouts of the uniqueid and thought i was seeing
more than necessary...)

Thanks, Mark

This is not correct.  CometActors with default LifeSpan are kept around for
the duration of the session.

[Lift] Caching Comet Actors

[Java1Guy]

Hey all!
I'm having great luck coding up my web site which consists of a
handful of pages each of which contains a Flot graph.  Behind each
page is a CometActor which dynamically updates the graph.
Since appetite grows while dining, I'm now interested in optimizing a
bit.  I presume I have the default timeout value for cometactors and
it seems each time a page is hit a new CometActor object is
instantiated.  Seems like Lift could keep a cache of these around
based on URL and sessionid.  Is that something that has been
implemented and I'm not seeing it?  Something I should be
implementing?  Something planned in a future release? Other? Just
reduce the timeout value?

TIA for any input...

Re: [Lift] Foreign Key constraints are not created by schemify

[Derek Chen-Becker]

The code in the spec is:

person.companies ++= companies
person.save
// Break some joins
companies(3).delete_! // delete "4"
companies(6).delete_! // delete "7"
person.companies.refresh  // reload joins so joinEntity.company.obj
isn't cached
person

My plan is to make FKs an optional feature of Schemifier, so I'll modify
your spec to run without the FKs and then duplicate it to one with FKs that
expects an exception to be thrown.

[Lift] Documentation

[Daniel]

Hey,

I'm new to both Scala and Lift, but I don't have any professional Java
experience. It seems that all of the documentation available for Lift
is aimed at folks who have considerable professional experience with
Java already. Is there any documentation available aimed for people
like me who don't have very much Java enterprise experience (I'm a
student)?

I find that the Django and Rails documentation is very helpful, while
Lift's is somewhat impenetrable. Are there any plans to improve the
Lift documentation? It's the major obstacle preventing my adoption of
this otherwise impressive framework.

Thanks,
Daniel

[Lift] Re: Mapping virtual directories

[Mark Feeney]

What I ended up doing to "solve" this problem was configure the maven-
jetty-plugin to deploy a second webapp beside the main Lift app.  e.g.


org.mortbay.jetty
maven-jetty-plugin

/webapp
0



/images
/hdd/data/images





This deploys the main Lift app under development at /webapp, and a
second web app at /images.  By default, the images app acts like a
virtual directory.

This is good enough during development, but for production, if your
Lift app relies on /images, you'll have to do some external config on
the production server to make sure it's available.

Bit more of a writeup here, if you are interested:

Re: [Lift] Re: How to disable XHTML?

[Tim Nelson]

You need to remove the if guard on the first case match and change the
second parameter you are passing to Req. The second param is for the
context. Try this:

LiftRules.determineContentType = {
  case (Full(Req("location" :: "maps" :: "testmap" :: Nil, _,
GetRequest)), Full(accept)) => "text/html; charset=utf-8"
  case _ => "application/xhtml+xml; charset=utf-8"
}

[Lift] How to revert json to lift model?

[Xuefeng Wu]

Hi,

I store the lift model to json, but cannot revert json to lift model, any
idea?

For example:
My model:
class Book extends LongKeyedMapper[Book] with IdPK{
def getSingleton = Book

object name extends MappedPoliteString(this, 125)
object desc extends MappedTextarea(this, 1320)

}

and to json by toJs:
bookjson = {"$lift_class": "book", "name": " The Definitive Guide to Lift",
"id": 1, "desc": " The Definitive Guide to Lift"}

the lift model is not POJO, I don't how to revert json to lift model.


Could anyone give some suggest?

Re: [Lift] Re: Lift 1.1-M8

No, it is not in yet. 

This is currently on the 2_8_0 branch and will be in Lift 2.0 (Scala 2.8 keeps 
being put back)

Re: [Lift] Re: How to disable XHTML?

[Timothy Perrett]

You need to put it in your Boot.scala file. 

determineContentType is of PartialFunction[(Box[Req], Box[String]), String] 
type - this means that you can match on particular paths:

LiftRules.determineContentType = {
  case (Full(Req("some" :: "path" :: Nil, "pdf", GetRequest)), 
Full(accept)) 
if LiftRules.useXhtmlMimeType && 
accept.toLowerCase.contains("application/xhtml+xml") =>
"application/xhtml+xml; charset=utf-8"
  case _ => "text/html; charset=utf-8"
}

Re: [Lift] Re: Location on Mac?

[Timothy Perrett]

Correct - I generally only update the installers periodically with major or 
minor releases of maven... i haven't the time to update with every micro 
release.

As david points out, not everyone has mac ports installed. You can of course 
use the macports version - the lift installer is just an easy, standalone 
access route; take it or leave it. 

Cheers, Tim
