[Lift] Newbie question: action beforeSave data
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.
Regards,
Wibble

[Lift] Re: Newbie question: action beforeSave data
Ok, I am sorry for my previous rubbish
I solved the issue using vars in my Snippet and passing them to my
Post instance to validate and save.

[Lift] How to create an rss?
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] Error messages are not displayed - 2.0-M1
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.

Using lift:msgs/ I receive the same result.
S.notice works fine in the browser but S.error with a list of errors
does not work.
any advice? thanks,

it does not work even in the case of a single error on the form.
the result is always a List(Full(entries_code) : Description must not
be empty)

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

hi Adam,
thank you. It is exactly what I done
def validateAndSave (): Unit = currentEntry.validate match {
case Nil = currentEntry.save ; S.notice(currentEntry.title +
SAVED!)
case x = { x map { (e:FieldError) = S.error(e.msg) } }

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.

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.
