 wow, thats some ugly code man. Why dont you try something like:

 def validateAndSave {
   currentEntry.validate match {
     case Nil =
       currentEntry.save
       S.notice(currentEntry.title + SAVED!)
     case List(fielderror) = S.error(fielderror.msg)
     case _ =

 }

 I havent tested it of course, but just wanna show you how you could tidy up 
 your code somewhat.

 Cheers, Tim

Hi Marius,
I am using version 2.0-M1.

Now it works. This topic could be considered closed for me.
Thanks to all for your replies. Regards,
wibble.

 What Lift version are you using?

 If you are using an Ajax form lift:msgs showAll=true/ did not show
 the messages associated with ID's ... messages coming from FieldError.
 This is a defect I fixed about a week ago. Please use the latest lift
 build.

 If you just want to render all messages (regardles if they are
 associated with ID's or not) in one place  lift:msgs showAll=true/
 should be fine. But typically for field related message you could use
 lift:msg id=field_id/ which would render only messages associated
 with field_id id. As a side note lift:msgs/ only render messages
 that are not associated with any ID.

 Br's,
 Marius

   Hello,

   are you submitting the form with ajax?
   If so, see this thread:

  http://groups.google.com/group/liftweb/browse_thread/thread/e25d86a24...

   In short, check if doing:

   xs.map {i = S.error(i.msg) };

   instead of:

   S.error(xs);

   works.

Hi Jeppe,
lift:Msgs showAll=true does not work. Always the same result.

If the form does not contain errors the data are saved well and the
browser display S.notice(saved) correctly.
The S.error method returns a List[FieldError]. I receive a List with
the format of List(Full(tablename_field) : message)

this is a field of my database class:
[code]
object description extends MappedTextarea(this, 255) {
   override def displayName = Description
   override def validations =  valMinLen(1, S.??(description must
not be empty)) _ :: super.validations
 }

[/code]

Try adding showAll:

But default, Msgs doesnøt show field-level errors

[Lift] Error messages are not displayed - 2.0-M1

2010-02-06 Thread wibblecp
Hi all,
I'm newbie with lifts and I am having a little problem. I am using
Lift2.0-M1.

I have a snippet that runs the rescue of a model. The method is called
when the submit the form

[code]
def validateAndSave (): Unit = currentEntry.validate match {
  case Nil = currentEntry.save ; S.notice(currentEntry.title + 
SAVED!)
  case x = println(x) ; S.error(x);
}
[/code]

I am not able to view the error messages in the browser, but only in
the shell.
Instead of using S.error(x) I tried S.error(+x). Now when I submit a
form I see the error messages but the message looks like this:

[code]
List(Full(entries_code) : Description must not be empty,
Full(entries_title) : Title must not be empty;,
Full(entries_author_email) : Invalid email address)
[/code]

So, the message are not displayed as expected and I am not able to
understand the reason for S.error( + x) to read something.

Could anyone give me an advice?

Thanks for your helps.

Ragards,
w.

[Lift] How to create an rss?

2009-10-23 Thread wibblecp

hi guys,
I'm looking for a way to generate an rss feed with lift, I'm working
on something like this (from lift-book):

object OwnRssFeed extends XMLApiHelper {
  def dispatch: LiftRules.DispatchPF = {
case Req(rss ::   Nil, , GetRequest) = () = showArticles()
case Req(rss :: _ :: Nil, ,  _) = failure _
  }


def failure() : LiftResponse = {
  val ret: Box[NodeSeq] = Full(op id=FAILURE/op)
  NotFoundResponse()
}

def createTag(in: NodeSeq) = {
  println([CreateTag]  + in)
  rss version=2.0
  channel
  titletitle/title
  linkhttp://example.org/link
  descriptionExample.org/description
  languageen-us/language

  generatorLift WebFramework/generator
  {in}
  /channel
  /rss
}


def showArticles(): LiftResponse = {
  val a: Box[NodeSeq] = for(a - Article.find(By
(Article.published, true))) yield {
 a.toXML
  }
  a
}
}

obviously the yield into the definition of showArticles method break
the cycle to the first one.

Could you suggest me what I can do? I am evaluating lift and scala
just in a while.
Thanks for your attention.

[Lift] Newbie question: action beforeSave data

2009-10-22 Thread wibblecp

Hi all,
this is my first post, but I read you always, so I apologize if it
appear so simple. I am tasting this sensational web framework.

I'll try to explain using a simple and basic example.

Consider a post mapper model with a mappedString object named
permalink
I'd like to set this db field with something like this (defined in my
snippet)

pre
private def set_permalink(input : String) = {
val pattern1 = \s+.r
val pattern2 = /[^a-zA-Z0-9_]+/.r
pattern1 replaceAllIn(pattern2 replaceAllIn(input.toLowerCase,
), -)
}
/pre


My snippet look like this

pre
class ArticleSnippet extends StatefulSnippet{



  var _permalink = S.param(title).map(_.toString) openOr welcome

  def add(form: NodeSeq) : NodeSeq = {


 /** I am in wrong here **/
val article = Article.create.owner(User.currentUser)

.created_at(entryDate).permalink(set_permalink(_permalink))

.

def doBind(form: NodeSeq) =
  bind(article, form,
   title - post.title.toForm,
   
   
   submit - submit(Save, )
  )



}


}
/pre

My saved posts always have welcome as value for permalink field.

Could anyone give me any suggestion about it? I appreciate a lot this
group.
Thanks in adavce for your replies.
