Well assume you snippet returns a NodeSeq:

import net.liftweb.http._
import js._
import JE._
import JsCmds._

def myFunc(xml: NodeSeq): NodeSeq = {
  ...
  resultingNode ++ head{Script(OnLoad(Call(myStartupFunction)))}/
head
}


In the above example we are returning a head node as well which will
be merged by Lift automatically in the real page head. Then I'm
using Lift's JavaScript abstractions to call on load function
myStartupFunction. Instead of

head{Script(OnLoad(Call(myStartupFunction)))}/head you can also
use

head
script type=text/javascript charset=utf-8{
Unparsed(
 jQuery(document).ready(function() {
myStartupFunction();
  })
 )
   }

/head

[Lift] Re: Automatic background AJAX: best way to do it?

2009-07-30 Thread Nolan Darilek


On 07/28/2009 07:28 PM, David Pollak wrote:
 I'd do the REST API thing.  The mechanisms that Lift has for handling 
 API calls from the browser are numerous, but they are associated with 
 a session (you can do ajaxCall or a S.buildJsonFunc).


Oh cool. When I listened to the podcast interview and heard about 
fast-pathing AJAX calls, I realized that this was exactly what I wanted, 
and that there wasn't a need to create a separate URL space just to 
accomodate this page update functionality--at least, not explicitly in 
the sense of what I meant by API. Neat. Thanks for the method 
pointers, too, that helped me focus my reading a bit. So here's what I 
have. I have this JS code as an interface to the geolocation API:

function Location() {

   this.lat = 0;
   this.lon = 0;

   this.update = function(lat, lon) {
 this.lat = lat;
 this.lon = lon;
 this.onUpdate(lat, lon);
   };

   this.onUpdate = function(lat, lon) {};
}

var loc = new Location();

Next I wrote a snippet which needs to set loc.onUpdate to a function 
that calls into Lift to update the page. I have:

class Geolocation {

   def updatePosition(pos:String):JsCmd = Alert(Got an update: +pos)

   def update(in:NodeSeq):NodeSeq = script type=text/javascript
 loc.onUpdate = function(lat, lon) {
   {SHtml.ajaxCall(JsObj(lat - JsVar(lat), lon - 
JsVar(lon)), updatePosition _)._2}
 };
/script
}

Two issues here. First, how do I get those braces around the JS function 
containing the ajaxCall into my HTML? Seems like there should be a way 
to escape braces so I can include them in NodeSeq, but \{ didn't seem to 
do it. I'm also quite new to JS as well, so perhaps there's a better way 
to set that callback. All I can come up with is changing the callback 
signature to accept an object rather than individual values so perhaps I 
can set it directly to the Lift-generated function, but I think I'd 
rather have raw values for individual position components for now.

2. Ideally, I'd like for the JsObj to be an actual Map[String, Float]. 
Is there a way to do this? An included JSON parser that'd convert the 
string to a type I specify, perhaps? (assuming I'd have to give some 
sort of hint for Float vs. other numeric types, anyway)

Thanks. Wow, this really makes AJAX development something I'd actually 
enjoy doing. :)

[Lift] Re: How to use Mapper and record framework

2009-07-30 Thread Giuseppe Fogliazza


Dear Pravin.
Your requests address very basic behaviour of the framework, and you
should not experience any problem in adapting examples from the
aforementioned book.
Even simpler you could follow the Todo example in Getting Started with
Lift accessible from liftweb site (http://liftweb.net/docs/
getting_started/mod_master.html).
Related to persistency at the moment you should concentrate on using
Mapper.
Creating your model object is a breeze. Create a MyItem.scala file
with the following entities (your project should have a model package
to contain this stuff)

class MyItem extends LongKeyedMapper[MyItem] with IdPK {
def getSingleton = MyItem
object name extends MappedPoliteString(this,64)
}
object MyItem extends MyItem with LongKeyedMetaMapper[MyItem]


Modify the Schemifier line in Boot.scala to add your MetaMapper object
Schemifier.schemify(true, Log.infoF _, User, MyItem)

... and now you can start having fun in creating the next web killer
app using Lift.

Regards
Giuseppe

  Nile,
 
  Scala imports are relative unless the path of the import is prefixed by
  _root_.  This behavior is the subject of fierce discussion on the
 Scala
  list.  What does relative mean?  It's like this:
 
  import net.liftweb._
  import http._ // imports net.liftweb.http._
 
  The problem is that if you have a JAR with some net.java.blah package in
 it,
  the Scala compiler will look to resolve java.concurrent._ as
  net.java.concurrent._
 
  We've generally tried to be explicit about using _root_ for all our
 imports,
  etc., but some lazy good for nothing Lift committers (I'm thinking about
  me), don't always follow the rule... and this has led to the pain you
 are
  experiencing.
 
  So, I don't know how Maven uses your environment variables, but that's

 Hey guys,

 I've been taking a look at Jersey and how it operates with Lift by way
 of the recent integration that cropped up on dev.java.net...

Though it did start here first! :)
http://www.nabble.com/using-Lift-templates-stand-alone-inside-other-frameworks-like-JAXRS--td23177478.html#a23558689

BTW it was only when there was lukewarm response on the fork I created
at github that I popped it into Jersey instead. Though David did most
of the heavy lifting hacking Lift to make templates reusable outside
of Lift's normal servlet+controller layer

 From my perspective, I see how having a standard RS service framework
 could be helpful, but it appears to bypass important lift concepts
 like SiteMap etc so I'm just wondering what the benefit of using such
 a layer would be over using DispatchPF etc to create REST services or
 serving xml fragments for templates? (I have no idea about Jersey
 apart from the basic docs ive read, so if im missing a major benefit
 id love to hear discuss)

As David said there are strengths and weaknesses to both approaches. I
see them as alternatives really; use one approach or the other or mix
them if required. My main motivation of the original Jersey - Lift
integration was to enable JAXRS folks to reuse Scala/Lift code for
templating instead of the joy that is JSP/JSP EL/JSTL/custom tag

I'd always assumed the SiteMap and JAXRS were kinda separate parts of
the URI space. Though having said that I've just noticed that using
Jersey + Lift trunk together in an application is currently broken
unless there is some kind of SiteMap defined :). I wonder if one day
we can kinda get Jersey to expose its own SiteMap (of sorts) into
Lift's SiteMap?

[Lift] JSON form with

2009-07-30 Thread James Kearney


I think the current implementation of the JSON form is broken.

If you put an  in a text field and try to submit it via a JSON form
it doesn't get handled correctly.

To be precise the formToJSON function in jlift.js doesn't work, and
again to be more precise the params method is broken / not fit for
purpose.

The params method (line 249) calls s.join() and then returns but it
doesn't escape the  character (it also uses = but doesn't escape
that). If the params function does what I think it is supposed to do
which is split paramters for a URL then it should really call
encodeURI on the values.

That aside I don't think the formToJSON function should be using the
param function. It gets a JSON object from jQuery serializeArray makes
it into a string split by  and = then goes and splits based on  and
= again building up some JSON (as a string) then parses the JSON. Why
not operate on the JSON from jQuery from the start.
e.g.

formToJSON : function(formId)
   {
   json = jQuery(# + formId).serializeArray();
   ret = {}

   for (var i in json)
   {
   var obj = json[i]

   ret[obj.name] = obj.value
   }

   return ret;
   }

This does work differently from before since it won't call functions
like params does but I don't think jQuery's serializeArray puts
functions in the object it returns so that is not needed.

[Lift] ajaxCall jlift.js and json2.js

2009-07-30 Thread James Kearney


I wanted to use ajaxCall on a page but it didn't seem to be working
due to javascript issues.

Eventually I found that I needed to include
script type=text/javascript src=classpath/jlift.js /

in the page.

I just wanted to check that you need to manually include these on
every page that uses ajax or should it be included automatically and I
have messed up the configuration some how.

Correct, you do indeed need to include this in a page where you want
to use json forms etc...

 I wanted to use ajaxCall on a page but it didn't seem to be working

 Eventually I found that I needed to include

 I just wanted to check that you need to manually include these on
 every page that uses ajax or should it be included automatically and I
 have messed up the configuration some how.

  I think the current implementation of the JSON form is broken.

  If you put an  in a text field and try to submit it via a JSON form
  it doesn't get handled correctly.

  To be precise the formToJSON function in jlift.js doesn't work, and
  again to be more precise the params method is broken / not fit for
  purpose.

  The params method (line 249) calls s.join() and then returns but it
  doesn't escape the  character (it also uses = but doesn't escape
  that). If the params function does what I think it is supposed to do
  which is split paramters for a URL then it should really call
  encodeURI on the values.

  That aside I don't think the formToJSON function should be using the
  param function. It gets a JSON object from jQuery serializeArray makes
  it into a string split by  and = then goes and splits based on  and
  = again building up some JSON (as a string) then parses the JSON. Why
  not operate on the JSON from jQuery from the start.
  e.g.

  formToJSON : function(formId)
             {
                 json = jQuery(# + formId).serializeArray();
                 ret = {}

                 for (var i in json)
                 {
                     var obj = json[i]

                     ret[obj.name] = obj.value
                 }

                 return ret;
             }

  This does work differently from before since it won't call functions
  like params does but I don't think jQuery's serializeArray puts
  functions in the object it returns so that is not needed.

[Lift] H2 mapper problem

2009-07-30 Thread Tim N


I am using an H2 database for my lift app. If I start with a clean
database and let schemifier create the tables, the tables get created
ok, but then I get a java.util.NoSuchElementException: key not found:
fsite_users where fsite_users is my User table. The table is created
and the app runs fine after ward. If I set schemifier to only validate
the db, I get the same error, so it seems to me like it's the code
that tries to verify the schema is where the problem lies. I thought
it might be a case issue, so I tried it with all uppercase table
names, but I got the same problem. I also tried this with various
versions of lift.

Any Ideas?

 I have just one more question: is this normal for save to throw an

 less 'exceptional' than just a failure to save. I guess this was a
 choice Derby made, not Lift...


This is a correct choice.  If you are trying to insert a second record with
an identical primary key should generate an exception.

You could try:

Cat.find(foo) openOr Cat.create.mac(foo)

This will find an existing record or create a new one.

Hey guys,

I've been taking a look at Jersey and how it operates with Lift by way
of the recent integration that cropped up on dev.java.net...

Though it did start here first! :)

http://www.nabble.com/using-Lift-templates-stand-alone-inside-other-frameworks-like-JAXRS--td23177478.html#a23558689

Strike that - pilot error! I'd broken the web.xml in that application
to disable Jersey's filter, DOH :). Jersey + Lift works fine with
1.1-SNAPSHOT and 1.1-M3 of Lift.

I wonder if one day
we can kinda get Jersey to expose its own SiteMap (of sorts) into
Lift's SiteMap?

There's a way to dynamically create submenus based on a function in SiteMap.
We could wire that up to Jersey's mechanisms to expose dynamic stuff via
SiteMap.

Also, a lot of Lift's dispatch stuff is based on PartialFunction.
PartialFunction is just apply and isDefinedAt... so we can build partial
functions based on the data supplied by Java frameworks and dynamically
dispatch from the underlying stuff.

[Lift] Odd XML parsing issue

2009-07-30 Thread Ewan


Not sure what I have messed up here but if I have a hardcoded link in
a template page where the href includes query params the lift runtime
stacktraces.  As an example a href=http://www.yahoo.com?
a=4b=5Test/a blows up - see below.  Removing the b=5 and all is
well.  The doctype is:

[Lift] radio input trouble

2009-07-30 Thread george


I am trying to follow the radio input example in the Lift book(s), but
I cannot get it to work.

Firstly, the example in the book uses this call to the SHtml.radio
function

SHtml.radio(colorMap.keys.toList, Empty, myColor = colorMap(_))

Using Lift 1.1-SNAPSHOT and Scala 2.7.5 This gives me the error:

missing parameter type for expanded function ((x$1) = colorMap(x$1))
colour - radio(colorMap.keys.toList, Empty, myColor = colorMap(_) )


So I change my code to the below:

...
var myColor : Color = _
val colorMap = Map(Red - Color.red, White - Color.white, Blue -
 Color.blue)

def renew(xhtml : NodeSeq) : NodeSeq = {
  bind(form, xhtml,
colour - radio(colorMap.keys.toList, Empty, (a:String) =
myColor = colorMap(a) )
  )
}
...

But this yields the following error:

Seems like the bind function doesn't like the ChoiceHolder[String]

[Lift] Re: H2 mapper problem

2009-07-30 Thread Tim N


This issue has been entered. (40)

I was able to narrow it down to only being a problem if a user/
password are specified. I'm not sure if a user/password are needed in
embedded mode, but I filed the issue anyway.

Thanks

[Lift] Getting Started tutorial - not understanding some syntax

2009-07-30 Thread ben


Hi,

I feel I must apologise for this  post ... I've only been doing scala
for a week, and lift for 3 days, but I'm stuck.
I'm coming from an experienced java background, just struggling with
some scala constructs.

I feel I understand the basics of lambda and function literals - but
I'm blown away by some of the syntax in the lift Getting Started
tutorial.
For example, given :

val mylist = Array(1,2,3)
mylist..foreach(v = println(v)

Here I understand where v comes from - its each int in the list.

In the tutorial (http://liftweb.net/docs/getting_started/
mod_master.html)
there is a function desc (Listing 15) :

private def desc(td: ToDo, reDraw: () = JsCmd) =
 swappable(span{td.desc}/span,
 span{ajaxText(td.desc,
 v = {td.desc(v).save; reDraw()})}
 /span)

For my own brain to try and break it down, I have :

  private def desc(td: ToDo, reDraw: () = JsCmd) = {
val myFunctionLiteral = (xxx: String) = {td.desc(xxx).save;
println(!Desc function : + xxx); reDraw()}

swappable(span{td.desc}/span,
  span{ajaxText(td.desc, myFunctionLiteral)}/span)
  }

This is called from the doList method :

private def doList(reDraw: () = JsCmd)(html: NodeSeq): NodeSeq =
 toShow.
 flatMap(td =
   bind(todo, html,
  desc - desc(td, reDraw)
   ))

I understand where the ToDo object td is coming from, and how the
reDraw thing works, and how they are passed to the desc function,
but what I don't understand at all is where the val xxx in
myFunctionLiteral comes from ?
How is it passed into the function ? Is it currying ?

I'm sorry for such a vague question, I'm totally at sea here.

Thankyou for reading this, and for any help you may provide !

Ben

[Lift] Re: Getting Started tutorial - not understanding some syntax

Hello Ben!

the following:

val square = (x:Int) = x * x

val square is the equivalent of a final reference in Java.

(x : Int) = x * x

This constructs a Function instance that takes an Int and returns that Int
squared.

The equivalent Java code would be something like:

interface FunctionR,P //We're ignoring variance here, as to not confuse
{
public R call(P p);
}

final FunctionInteger,Integer square = new FunctionInteger,Integer() {
 public Integer call(Integer i)
 {
 return i * i;
 }
}

And then you can do:

square.call(2) // 4

So, back to Scala:

val square = (x : Int) = x * x

square(2) // 4

Thanks marius for pointing me in the right direction. I nearly got
there :)

Both of the following work:

SHtml.radio(colorMap.keys.toList, Empty, (a:String) = myColor =
colorMap(a) ).toForm

// Or if you want to override the XHTML output
SHtml.radio(colorMap.keys.toList, Empty, (a:String) = myColor =
colorMap(a) ).flatMap(c = (span{c.xhtml} {c.key.toString}/span))

Is there a better way to override XHTML output of the ChoiceHolder?
Could it be done once somewhere for the whole application?

A follow up question that just made me wonder, what is the diference

and
def square(x:Int):Int = x * x

?

Well, thank you.




 A follow up question that just made me wonder, what is the diference
 between

 val square = (x : Int) = x * x


This creates a final reference to a new function instance



 and
 def square(x:Int):Int = x * x


This creates a method

Now, you can transform a method into a function by adding an underscore
after it, like this:

def square(x : Int) = x * x

val sq = square _ //--- notice the underscore. (I always think of it as
detaching the method from an instance)

This is what the Scala REPL says:

scala def square(x : Int) = x * x
square: (Int)Int

scala val vsquare = (x : Int) = x * x
vsquare: (Int) = Int = function

scala val v2square = square _
v2square: (Int) = Int = function

scala square(2)
res0: Int = 4

scala vsquare(2)
res1: Int = 4

scala v2square(2)
res2: Int = 4






 ?

  Hello Ben!
 
  the following:
 
  val square = (x:Int) = x * x
 
  val square is the equivalent of a final reference in Java.
 
  (x : Int) = x * x
 
  This constructs a Function instance that takes an Int and returns that
 Int
  squared.
 
  The equivalent Java code would be something like:
 
  interface FunctionR,P //We're ignoring variance here, as to not confuse
  {
  public R call(P p);
 
  }
 
  final FunctionInteger,Integer square = new FunctionInteger,Integer()
 {
   public Integer call(Integer i)
   {
   return i * i;
   }
 
  }
 
  And then you can do:
 
  square.call(2) // 4
 
  So, back to Scala:
 
  val square = (x : Int) = x * x
 
  square(2) // 4

[Lift] Re: Getting Started tutorial - not understanding some syntax

2009-07-30 Thread ben


Hi Viktor,

Thanks for your reply.

I do understand the simple examples, like the one you were kind enough
to post.

My problem is that I just can't seem to break through from the simple
examples to the code in the Getting Started tutorial 

To elaborate, given the following in a scala console :

scala val square = (x : Int) = x * x
square: (Int) = Int = function

scala square(2)
res5: Int = 4

I can easily (in my mind) see how that function literal works - ie
function square takes an int and apply(s) a square on the value passed
in. In my mind I can see where x is coming from - its clearly the
value 2 passed in the operation square(2) - but I just don't get
where the string xxx (in the code posted (from the tutorial - see
Listing 15) is actually coming from ... there never seems to be the
string passed to the function !

[Lift] Re: Getting Started tutorial - not understanding some syntax

(If I've understood your question correctly)

the definition of ajaxText is as follows:

  def ajaxText(value: String, func: String = JsCmd): Elem =
ajaxText_*(value, Empty, SFuncHolder(func))

So what you're doing is that you're sending a callback function to ajaxText,
and it will be called with a String later.

Your myFuncionLiteral is passed as a parameter to ajaxText.  When the
ajaxText box is submitted by the user, your function is applied to the
String typed by the user.

This is a common pattern in Lift... associate a function on the server with
an HTML element on the client.  That way, Lift abstracts away the HTTP
request/response cycle and allows you to focus on what happens when the
user does something?



 How is it passed into the function ? Is it currying ?

 I'm sorry for such a vague question, I'm totally at sea here.

 Thankyou for reading this, and for any help you may provide !

[Lift] Re: Getting Started tutorial - not understanding some syntax

On Thu, Jul 30, 2009 at 2:02 PM, DFectuoso santiago1...@gmail.com wrote:


 Viktor, that was a great explanation, im sure ben will apraciate that
 kind of teaching =)

 A follow up question that just made me wonder, what is the diference
 between

 val square = (x : Int) = x * x
 and
 def square(x:Int):Int = x * x


Scala has two core things: Objects and Methods.

In the first example, we create an instance of an object which implements
the Function1[Int, Int].  You can call the apply() method on square either
by using square.apply(2) or square(2).  The latter syntax is expanded to the
former by the compiler.

The second example is a method definition.  The method is defined on a class
and called on an instance of the class.

Methods can take type parameters.  Functions have their type parameter
defined at instantiation time.

  Hello Ben!
 
  the following:
 
  val square = (x:Int) = x * x
 
  val square is the equivalent of a final reference in Java.
 
  (x : Int) = x * x
 
  This constructs a Function instance that takes an Int and returns that
 Int
  squared.
 
  The equivalent Java code would be something like:
 
  interface FunctionR,P //We're ignoring variance here, as to not confuse
  {
  public R call(P p);
 
  }
 
  final FunctionInteger,Integer square = new FunctionInteger,Integer()
 {
   public Integer call(Integer i)
   {
   return i * i;
   }
 
  }
 
  And then you can do:
 
  square.call(2) // 4
 
  So, back to Scala:
 
  val square = (x : Int) = x * x
 
  square(2) // 4

   Hi,
 
   I feel I must apologise for this  post ... I've only been doing scala
   for a week, and lift for 3 days, but I'm stuck.
   I'm coming from an experienced java background, just struggling with
   some scala constructs.
 
   I feel I understand the basics of lambda and function literals - but
   I'm blown away by some of the syntax in the lift Getting Started
   tutorial.
   For example, given :
 
   val mylist = Array(1,2,3)
   mylist..foreach(v = println(v)
 
   Here I understand where v comes from - its each int in the list.
 
   In the tutorial (http://liftweb.net/docs/getting_started/
   mod_master.html
 http://liftweb.net/docs/getting_started/%0Amod_master.html
   )
   there is a function desc (Listing 15) :
 
   private def desc(td: ToDo, reDraw: () = JsCmd) =
swappable(span{td.desc}/span,
   span{ajaxText(td.desc,
   v = {td.desc(v).save; reDraw()})}
   /span)
 
   For my own brain to try and break it down, I have :
 
private def desc(td: ToDo, reDraw: () = JsCmd) = {
  val myFunctionLiteral = (xxx: String) = {td.desc(xxx).save;
   println(!Desc function : + xxx); reDraw()}
 
  swappable(span{td.desc}/span,
span{ajaxText(td.desc, myFunctionLiteral)}/span)
}
 
   This is called from the doList method :
 
   private def doList(reDraw: () = JsCmd)(html: NodeSeq): NodeSeq =
toShow.
flatMap(td =
 bind(todo, html,
desc - desc(td, reDraw)
 ))
 
   I understand where the ToDo object td is coming from, and how the
   reDraw thing works, and how they are passed to the desc function,
   but what I don't understand at all is where the val xxx in
   myFunctionLiteral comes from ?
   How is it passed into the function ? Is it currying ?
 
   I'm sorry for such a vague question, I'm totally at sea here.
 
   Thankyou for reading this, and for any help you may provide !

[Lift] New Mapped Fields (MappedTimestamp and MappedMac)

2009-07-30 Thread Peter Robinett


Hi all,

As some of you may have noticed, I have been playing around with
timestamps[1] and mac addresses[2] in my models. I really like
Mapper's specialized fields, both to make it easier for people to read
model definitions and to better ensure that only valid values are used
along all levels of the service, from the persistence to the
presentation layers.

So, I would like to propose an effort to develop more specialized
fields, starting with MappedTimestamp and MappedMac. I talked to David
today and he is willing to provide some advice. Hopefully this will
prove a useful way for me to improve my Scala knowledge and contribute
to Lift.

Focusing just on the two mapped fields I mentioned, do you have any
comments how that should be implemented? My thinking is that
MappedTimestamp would be stored as a java.util.date and MappedMac as
a  String, converting both of them to Longs for the database in the
interest of saving space.

Are there any other mapped fields you'd like to see? I'll add that I
think using the units compiler plugin[3] looks cool[4] but probably
would be considered to create an unacceptable dependency.

I'll be needing a MappedMap in one of my upcoming projects, basically a 
way of associating keyword/value pairs with my models. I'd really rather 
avoid the extra overhead of creating models and associations for these 
pairs, especially since they are never needed outside of the model 
itself. In the older Merb incarnation of this project, I just dumped the 
data to JSON and stored it in a text field on the object, kinda a poor 
man's document database if you will. :)

[Lift] Re: New Mapped Fields (MappedTimestamp and MappedMac)

2009-07-30 Thread g-man


I've been working on implementing a better Date solution in my apps,
and the best one I have found is to use a Long to store the instant in
millis, then pass that down the line in response, let JavaScript do
all the conversions to display and validations for submission client-
side, and then send back millis in a request.

It's just an world-wide instant in time, after all, with no time zone
(UTC), and I can do all my date math easily with millis.

True, it's not human-readable in the database, but so what? True,
relying on JS may not be a universal solution, but how many users
don't have JavaScript turned on?

This approach would fit in well with your idea, being a Long, but I
see no need to bring in the Date object at all. Even if you want to
let the Java Date do any work, it can still use the millis perfectly,
and mySQL strips off the milli-portion of its timestamp data type
anyway, which is why it's useless.

Walks like a Date, talks like a Date, but it's a milli...

[Lift] AJAX form with returned NodeSeq

Hey, all,

I want to create a form that on submission executes some serverside code
that returns a NodeSeq, and then updates the page with that xml. It seems
like some combination of AjaxForm and SetHtml should do what I want, but I
can't seem to get the server to send a response to the client that can be
used to update the html.

Is there a lifty way of doing this?

It's likely that the editors are not emitting well formed XHTML and that's
causing the problems.

Please run one or both in Firefox using Firebug and let's see if the
exceptions are happening in some assignment to innerHTML.

 You can't add this to a MetaMapper trait, it must be part of a trait that's

[Lift] Re: Wymeditor or FCKEditor

Lift, by default, serves with a mime type of application/xhtml+xml (except
to IE).  This puts browsers into a very strict mode for parsing and it means
that scripts may not use write to change the DOM.
So, what/where is the exception?

Are you serving the static page as text/html or application/xhtml+xml ?

When I browse to
http://files.wymeditor.org/wymeditor/trunk/src/examples/01-basic.html it's
served as text/html

I think I had the same problem, and if I recall correctly it was because lift

the H2 console. I think my code actually uses ;schema=... in the url.

Well assume you snippet returns a NodeSeq:

In the above example we are returning a head node as well which will
be merged by Lift automatically in the real page head. Then I'm
using Lift's JavaScript abstractions to call on load function
myStartupFunction. Instead of

head{Script(OnLoad(Call(myStartupFunction)))}/head you can also
use

head

 I'd do the REST API thing.  The mechanisms that Lift has for handling 
 API calls from the browser are numerous, but they are associated with 
 a session (you can do ajaxCall or a S.buildJsonFunc).


Oh cool. When I listened to the podcast interview and heard about 
fast-pathing AJAX calls, I realized that this was exactly what I wanted, 
and that there wasn't a need to create a separate URL space just to 
accomodate this page update functionality--at least, not explicitly in 
the sense of what I meant by API. Neat. Thanks for the method 
pointers, too, that helped me focus my reading a bit. So here's what I 
have. I have this JS code as an interface to the geolocation API:

function Location() {

   this.lat = 0;
   this.lon = 0;

   this.update = function(lat, lon) {
 this.lat = lat;
 this.lon = lon;
 this.onUpdate(lat, lon);
   };

   this.onUpdate = function(lat, lon) {};
}

var loc = new Location();

Next I wrote a snippet which needs to set loc.onUpdate to a function 
that calls into Lift to update the page. I have:

class Geolocation {

   def updatePosition(pos:String):JsCmd = Alert(Got an update: +pos)

   def update(in:NodeSeq):NodeSeq = script type=text/javascript
 loc.onUpdate = function(lat, lon) {
   {SHtml.ajaxCall(JsObj(lat - JsVar(lat), lon - 
JsVar(lon)), updatePosition _)._2}
 };
/script
}

Two issues here. First, how do I get those braces around the JS function 
containing the ajaxCall into my HTML? Seems like there should be a way 
to escape braces so I can include them in NodeSeq, but \{ didn't seem to 
do it. I'm also quite new to JS as well, so perhaps there's a better way 
to set that callback. All I can come up with is changing the callback 
signature to accept an object rather than individual values so perhaps I 
can set it directly to the Lift-generated function, but I think I'd 
rather have raw values for individual position components for now.

2. Ideally, I'd like for the JsObj to be an actual Map[String, Float]. 
Is there a way to do this? An included JSON parser that'd convert the 
string to a type I specify, perhaps? (assuming I'd have to give some 
sort of hint for Float vs. other numeric types, anyway)

Thanks. Wow, this really makes AJAX development something I'd actually 
enjoy doing. :)

[Lift] Re: New Mapped Fields (MappedTimestamp and MappedMac)


Maybe I'm missing something that was said, but why can't MappedTimestamp extend

Peter Robinettpe...@bubblefoundry.com wrote:


Hi all,

As some of you may have noticed, I have been playing around with
timestamps[1] and mac addresses[2] in my models. I really like
Mapper's specialized fields, both to make it easier for people to read
model definitions and to better ensure that only valid values are used
along all levels of the service, from the persistence to the
presentation layers.

So, I would like to propose an effort to develop more specialized
fields, starting with MappedTimestamp and MappedMac. I talked to David
today and he is willing to provide some advice. Hopefully this will
prove a useful way for me to improve my Scala knowledge and contribute
to Lift.

Focusing just on the two mapped fields I mentioned, do you have any
comments how that should be implemented? My thinking is that
MappedTimestamp would be stored as a java.util.date and MappedMac as
a  String, converting both of them to Longs for the database in the
interest of saving space.

Are there any other mapped fields you'd like to see? I'll add that I
think using the units compiler plugin[3] looks cool[4] but probably
would be considered to create an unacceptable dependency.

[Lift] Re: User validation by admin


I'm not clear what you're suggesting.
Currently there are two methods. sendValidationEmail takes a user and sends him 
an email. signup has a nested function, testSignup, which (1) sets validated 
based on skipEmailValidation, and resets uniqueId; (2) if skipEmailValidation 
log in; otherwise sendEmailValidation.
Are you saying to make testSignup an overridable method? Wouldn't something 
finer-grained be better?

David Pollakfeeder.of.the.be...@gmail.com wrote:

Sounds like a worthy addition.  I'd suggest that rather that doing more

skipEmailValidation flag.

 Hi. I would like to customize the way that user registration is validated

 Here are some possible approaches:
 1. Set skipEmailValidation to true and build the mechanism from scratch in

 2. Override signup, and implement it similar but different.
 3. Add a flag to lift to leave the user NOT validated, but not to send the
 email. Then either send the email manually, or provide a way for the admin
 to validate users.
 4. Provide a hook to directly specify who the email should go to.
 What do people think?
