[Lift] Handle Exception

[Xuefeng Wu]

Hi,
I have a question about exception handle in Lift.

*How could I pop a error dialog except redirect?*
*
*
*Lift have LiftRules.exceptionHandler.prepend to handle exception.*
LiftRules.exceptionHandler.prepend {
  case (mode, state, ex) => RedirectResponse("/error")
  // how could I pop a error dialog?
 }



And I found that Lift could handle exception from snippet , for example：
  def throwExceptionB(in: NodeSeq): NodeSeq = {
throw new RuntimeException("throw exception")
a(() => {Alert("Text throw exception")},
 Text("throw exception")
)
  }


But I find lift didn't throw exception if it rise from lift inside:
   def throwExceptionB(in: NodeSeq): NodeSeq = {
a(() => {throw new RuntimeException("throw exception");Alert("Test throw
exception")},
 Text("throw exception")
)
   }
The exception will be printed at server side but not the client.
I think Lift should also could handle it.

Re: [Lift] Re: How do I go about implementing my own auth?

[Xuefeng Wu]

Could SiteMap authorize the editable text?
I use swappable some where and do not know how to authorize it.

Re: [Lift] 280_port and yuicompressor problem

If you google "[yuicompressor:compress {execution: default}]" would find so
many information about this.
It's not caused by scala2.8 or lift.

It's good way to handle exception.

And I think it's better that it could pop dialog to tell users what's wrong.

Re: [Lift] Sitemap - rendering "title" attributes for the links

[Xuefeng Wu]

You could add MetaData 'title' by Elem 's method '%'
some page % ("title" -> "what will happen when you click
on this
link")

or use { }
some page

Re: [Lift] Re: **Important** Announcing the Lift 2.0 branch

[Xuefeng Wu]

I mean that lift1.1 and lift2.0 may have the same futures,
But lift1.1 is for Scala2.7 and lift2.0 is for Scala2.8.
With Scala2.8 stable , the lift1.1 could not be enhanced.

It's better than Lift2.0-Scala2.7 and Lift2.0-Scala2.8.

And there're better explain why Lift2.0 and Lift1.1 if people ask what's the
different between Lift2.0 and Lift1.1?

Hi Alex,

I found new ModalDialog(html: NodeSeq, css: Box[JsObj]),
 the parameter 'css' type is JsObj instead of String.

Could you tell me the reason?

I'm working on a customer widgets and have the same case.

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] 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: highlight the lift notices in some seconds

[Xuefeng Wu]

Hello Marius,

I have an other question about S.error.
When I use: S.error("can not delete this department.")

I get:
try{jQuery("#lift__noticesContainer__").each(function(i) {this.innerHTML =
"Errorcan not delete. ";});} catch (e) {}

What I want this
try{jQuery("#*lift__noticesContainer___error*").each(function(i)
{this.innerHTML = "Errorcan not delete. ";});}
catch (e) {}

Why it's lift__noticesContainer__ but not lift__noticesContainer___error?

Did I miss something?

Re: [Lift] Re: highlight the lift notices in some seconds

[Xuefeng Wu]

It's not make sense for my project.
I separate business  transaction from UI logic.
When create or update business model will occur notice or error,
and then do something for UI by the business transaction

for example:
business:
def MyBusinessTransaction(v: String) : Option[MyModel] = {
  val myModel = MyModel.create.title(v)
  myModel.validate match {
  case Nil => {myModel.save();Some(myModel)}
  case xs => {S.error(xs);None}
  }
}


Snippet
def doSomething(): JsCmd = MyBusinessTransaction(v) match {
case Some(v) => //do something for UI, such as replace the old value
case None => //notice what's wrong. *I could code ** fadeOutErrors(5
seconds, 1 second) if want, but should I code every where?*
}


Or there're any other practice for separate business from UI?

Re: [Lift] lift-stamped - Traits for logging changes MetaMapper-Records

[Xuefeng Wu]

That's great!

What's more,
I'm not sure whether every model need
creator/createDate,lastUpdator/lastUpdateDate?
I want to have a Action Log, which could record user activities.
Any model change history or change object could restore from action log

Did any one do something about this?

I think It's better I could configure it, but not code every where.

Re: [Lift] Re: highlight the lift notices in some seconds

[Xuefeng Wu]

Yes, I do something like
 // do the DB stuff
 vmyMapper.validate match ｛
   case Nil =>
   case xs => S.error(xs)
｝

But I should always add fadeOutErrors(5 seconds, 1 second)?

I want lift highlight every error/notice information.

Re: [Lift] Re: highlight the lift notices in some seconds

[Xuefeng Wu]

But I use field validate, the notice and error are wrap by lift. Should I
append fadeOutErrors(5 seconds, 1 second)?

[Lift] highlight the lift notices in some seconds

[Xuefeng Wu]

Hi,

I want to highlight the lift notice and it will hide when timeout.
Should I code every request or only to config lift some where?

For example:
When use put items into the shopping cart, highlight the items some seconds
to notice the user.

Re: [Lift] Sharing data between snippet functions during a single HTTP request

[Xuefeng Wu]

Hi David & Ross,

Thank you for your help,
I understand RequestVar now, which muse be used in the same request.

My case is that I have a tree and a separate button.
When use click the tree node, the separate button should know which node is
selected.

Right now I replace the separate button when use click the tree node and it
worked.
I don't want to use session and I think it's better not replace the button.
But I don't have idea how to do.

My current solution is that when user select a tree node, I replace the add
button dependence on the node.

Re: [Lift] Sharing data between snippet functions during a single HTTP request

[Xuefeng Wu]

Hi Ross,

Yes it's not in the same request.

My case is:
When user select a tree node, I want to store this nodeId and If user click
a button to create a child node, I want to get the selected node.

I use ModalDialog when user click the button to create now node.

I use myId.is but get nothing.

Re: [Lift] Sharing data between snippet functions during a single HTTP request

[Xuefeng Wu]

Hi ,

When I use RequestVar get the message: RequestVar ... was set but not
read

My code like this:
object MyMgr {
  ...
  Loc.Snippet("myFoo",myFoo)
 ...
   object myId extends RequestVar[Long](0)

   def myFoo(xhtml: NodeSeq): NodeSeq = {

def selectNode = {

myId .set(vId)

}

   bind("",xhtml,
 "node"->a(() => selectNode, Text(nodeName))
)
   }

}

the RequestVar must be used at Class?

[Lift] seeing JVM BUG(s) - cancelling interestOps==0

[Xuefeng Wu]

Hi,

I always find the information from console:  seeing JVM BUG(s) - cancelling
interestOps==0

What's the reason?

I use jetty 6.1.21, and I'm afraid it will cause serious error if I deploy
the liftweb app in IBM WAS(WebSphere  App Server)

[Lift] Is this a defect at JqJsCmds.ModalDialog

[Xuefeng Wu]

Hi,

When I use ModalDialog I want to setup the css but fail,
My code would be:
ModalDialog(someHtml, "top: '10px'")

I found the ModalDialog code at Lift:
class ModalDialog(html: NodeSeq, css: Box[String]) extends JsCmd {
val toJsCmd = "jQuery.blockUI({ message: " +
AltXML.toXML(Group(S.session.map(s =>
s.fixHtml(s.processSurroundAndInclude("Modal Dialog",
html))).openOr(html)), false, true, S.ieMode).encJs +
(css.map(w => ",  css: '" + w + "' ").openOr("")) + "});"
  }

the css is wrap by " '  ' " ,
but I found http://malsup.com/jquery/block/#demos
the css is wraped by "{ }"


Is this a defect at JqJsCmds.ModalDialog or I do something wrong?

Such as http://code.google.com/p/rubycas-client/ This CAS client library is
designed to work easily with Rails.

I need a CAS SSO library with Rails.

[Lift] How to use TestRunner

[Xuefeng Wu]

Hello,

I'm working on lift testkit 1.1-M7 and want to write unit test.

I didn't find ReportFailure, TestKit at testing but found TestRunner
when use TestFramework.

I think it's interesting for mocking DB and web server, but I couldn't
find any help.

Could anyone explain it and give a demo how to use it?

[Lift] Re: How can call server 'ajax' function by my ajax code?

[Xuefeng Wu]

I want call function on the server side form client.
such as:
HTML client:
$.("#myLink").click(function{
//call server function
});

Server side:
def myFunction() :JsCmd = {
   JsRaw("alert("Ah~ you could call me from client directly!")")
}

[Lift] How can call server 'ajax' function by my ajax code?

[Xuefeng Wu]

Hi,

There're many ajax* control in SHtml such as ajaxButton and they can
call server function by 'liftAjax.lift_ajaxHandler
("F900890988391MRF=true", null, null, null); return false;' directly.

My question is that how could I call server 'ajax' function by my ajax
code? How could I know the function's "code" such as
"F900890988391MRF", or I can custom the "code"?

Thank you!
