[Lift] Re: Is this correct way to handle RESTful like URL in Lift Framework?
Or you could use something like if you'r building REST API's:
LiftRules.dispatch.append {
case Req(test :: _, suffix, reqType) = // return a () =
LiftResponse
}
or for non REST API you could use
LiftRules.statefulRewrite.append {
case RewriteRequest(ParsePath(test :: _, _, _, _), reqType, request)
= ...
}

If I have a URL likehttp://localhost/Test/edit/{id} and I would like
the {id} transform to a parameter instead of URL path part.
The problem is that if I have a template named edit.html under webapp/
Test, which is the template I use to edit an item.
And I have a Menu instance like the following:
code
Menu (Loc(Test, List(Test) - true, Test))
/code
It would only match URL likehttp://localhost/Test/edit, not anything
likehttp://localhost/Test/edit/1
Is it best way to do it by create a menu with RewriteRequest? Because
I found it a little boilerplate if I have lot URL pattern like this.
code
val menu = Menu(new Loc[Unit] {
override def name = Test
override def text = Test
override def link = (List (Test), true)
override def params = Nil
override def defaultValue = Full(())
def isTarget (path: ParsePath) = path match {
case ParsePath (List(Test, edit, id), _, _, _) = true
case _ = false
}
override def rewrite = Full ( NamedPF(Test) {
case RewriteRequest (path, _, _) if isTarget(path) =
RewriteResponse(List(Test, edit),
Map(id - 1024)) - ()
})})
/code

[Lift] JNDI error when switching to M8 ?
Hi all,
There is a problem that i switch the M7 to M8, the JNDI is error.
I didn't change anything before moving M7 to M8.
It seems that the Lift looks for the lift ConnectionIdentifier not
the OneDB or TwoDB.
###
java.lang.NullPointerException: Looking for Connection Identifier
ConnectionIden
tifier(lift) but failed to find either a JNDI data source with the
name lift or
a lift connection manager with the correct name
###
I have two DB connection, in the Boot.scala
###
object OneDB extends ConnectionIdentifier {
def jndiName = one
}
object TwoDB extends ConnectionIdentifier {
def jndiName = two
}
---
class Boot {
def boot {
if (!DB.jndiJdbcConnAvailable_?) {
DB.defineConnectionManager(OneDB, DBVendor)
DB.defineConnectionManager(TwoDB, DBVendor_2)
}
}
}
###
This work fine under the M7, but is broken in the M8,
Does anyone know what's wrong with it ?
Thanks for any suggestion!
Cheers,
Neil

Re: [Lift] Re: Ajax button + submitting a form
Hello,
thanks, but my use-case is a bit different.
I want the whole form to be still submitted using a POST (the normal way),
and only use ajax for a small fragment of the page (the element editor). So I
can't use ajaxForm(...), as this would make all submit buttons use ajax.

Thanks for your reply,

[Lift] Re: Is this correct way to handle RESTful like URL in Lift Framework?
You can use LiftRules.statelessRewrite which is processed very early
before the SiteMap comes into the picture. Hence you can rewrite at
this level. LiftRules.statefulRewrite is processed a little later on
(but you have full S context) but still before SiteMap is processed.
If this doesn't fit your needs, using your approach is not bad either.
Not sure where the boilerplate is as RESTfulLoc looks like a generic
one.

You dont need to have a form element in your templates for this to
work
because ajaxForm will wrap the result of the bind method.
For my listelements checkbox, I attach to the checkbox a function,
that adds an Id and the
checkbox value to a ListBuffer[(Boolean, String)]. (checked and not
checked boxes are submittet)
Then I filter the List for the selected values a do what I have to do
with them.
I the above code example, my save method does some db stuff and then
returning
a JsCmds.SetHtml(an html id, some html/snippet nodeseq) for a
redraw.
Hope this helps a little
with best regards

Hello,
I have a regular form, which is submitted with a POST (no AJAX here yet).
The form contains a list, to which you can add and remove elements using
AJAX. So the add and remove buttons are:
add - ajaxButton(Add element, () = { elements += new Element;
reDraw })
The reDraw method is a SetHtml for the whole form. Now this almost
works, with the exception that when I press the add button all other
changes in the form are discarded, as the form is not submitted. So, when
the button is pressed, I would need to submit the form using ajax and
execute a given function on the server. In the archives I found
SHtml.submitAjaxForm(formId) method, which I guess does what I need, but
I don't know how to combine it with an ajaxButton?

[Lift] Re: Ajax button + submitting a form
Well you could have a hidden for field containing some information
about the submitter, thus when you click the button you first set the
value of the hidden field and then call submitAjaxForm
Or Try:
ajaxButton(Press me would ya'?, SHtml.submitAjaxForm
(form_ID).toJsCmd, (some) = {
do your stuff here
})

There is also a related problem:
how can I have two ajax buttons on one form which submit the form and
execute different functions on the server?
Using the standard trick:
SHtml.ajaxForm(bind(...) ++ SHtml.hidden(submitFunction))
won't work, as I want different functions executed for different buttons.

Hello,
thanks, but my use-case is a bit different.
I want the whole form to be still submitted using a POST (the normal
way), and only use ajax for a small fragment of the page (the element
editor). So I can't use ajaxForm(...), as this would make all submit
buttons use ajax.

Re: [Lift] Re: Ajax button + submitting a form
Hello,
ajaxButton(Press me would ya'?, SHtml.submitAjaxForm
(form_ID).toJsCmd, (some) = {
do your stuff here
})
Looking at the source code I think this might work, but I'm having trouble
constructing the correct expression to pass to ajaxButton. The method signature
requires a Call instance, and SHtml.submitAjaxForm results in a command
(JsCmd). Is it possible to somehow combine the two?
Or maybe there is some other, lift-idomatic way to solve my problem?
I want to create a form with a list of elements, with three ajax buttons: add,
remove and save (adding/removing a row and persisting the list).
By the way, I think there's a small inconsistency; there are 7 overloaded
variants for ajaxButton:
ajaxButton(text: NodeSeq, func: () = JsCmd, attrs: (String, String)*): Elem
ajaxButton(text: String, func: () = JsCmd, attrs: (String, String)*): Elem
ajaxButton(text: NodeSeq, jsFunc: Call, func: () = JsCmd, attrs: (String,
String)*): Elem
ajaxButton(text: String, jsFunc: Call, func: () = JsCmd, attrs: (String,
String)*): Elem
ajaxButton(text: NodeSeq, jsExp: JsExp, func: String = JsCmd, attrs: (String,
String)*): Elem
and the last one doesn't have a text: String counterpart. Also the javadoc for
the last variant is missing information on what's jsExp and what's the
argument passed to func. My guess would be that jsExp is evaluated and the
result passed to func on the server?

I was referring to this signature:

attrs: (String, String)*): Elem
and not
def ajaxButton(text: NodeSeq, jsFunc: Call, func: () = JsCmd, attrs:
(String, String)*): Elem
jsExp will be called before sending the actual ajax. But this may be a
bit problematic if your jsExp sends the ajaxForm the ajax request is
processed asynchronously at js level meaning the the button ajax
request may be send before the actual ajax form processing is done.
I'm not sure if this fits your needs
Or maybe there is some other, lift-idomatic way to solve my problem?
I want to create a form with a list of elements, with three ajax buttons:
add, remove and save (adding/removing a row and persisting the list)
The first solution I described involving hidden fields will definitely
work. I don't think you need to do 2 ajax calls (one for the form and
one for the button) but piggy back the button information into a
hidden field and only submit the form:
Perhaps something like:
button onclick={(JqId(hidden_field_id) JqAttr(value, add)) +
+ SHtml.submitAjaxForm(form_ID).toJsCmd}blah/button
By the way, I think there's a small inconsistency; there are 7 overloaded
variants for ajaxButton:
ajaxButton(text: NodeSeq, func: () = JsCmd, attrs: (String, String)*): Elem
ajaxButton(text: String, func: () = JsCmd, attrs: (String, String)*): Elem
ajaxButton(text: NodeSeq, jsFunc: Call, func: () = JsCmd, attrs: (String,
String)*): Elem
ajaxButton(text: String, jsFunc: Call, func: () = JsCmd, attrs: (String,
String)*): Elem
ajaxButton(text: NodeSeq, jsExp: JsExp, func: String = JsCmd, attrs:
(String, String)*): Elem
and the last one doesn't have a text: String counterpart. Also the javadoc
for the last variant is missing information on what's jsExp and what's the
argument passed to func. My guess would be that jsExp is evaluated and the
result passed to func on the server?
Yes jsExp is being evaluated and its result is being sent to server.
Please open a defect for this inconsistency.

[Lift] Re: Lift and Akka Actors in comparison?
Hello, I read only little about AKKA, but I read that the Lift Actors are now decopled and you can use AKKA Actors or Scala Actors as implementation. with best regards On 9 Jan., 08:48, Franz Bettag fr...@bett.ag wrote: Hey guys, i was wondering if i can implement a real distributed application with lift and akka.

On the google groups of akka i found out that this only works with akka-actors.

[Lift] Re: Ajax button + submitting a form
Sorry I think the syntax would be (I haven't tested it though):
button onclick={((JqId(hidden_field_id) JqAttr(value, add))
SHtml.submitAjaxForm(form_ID)).toJsCmd}add/button
button onclick={((JqId(hidden_field_id) JqAttr(value,
edit)) SHtml.submitAjaxForm(form_ID)).toJsCmd}edit/button
button onclick={((JqId(hidden_field_id) JqAttr(value,

Hello,

Looking at the source code I think this might work, but I'm having trouble
constructing the correct expression to pass to ajaxButton. The method
signature requires a Call instance, and SHtml.submitAjaxForm results in a
command (JsCmd). Is it possible to somehow combine the two?
I was referring to this signature:
def ajaxButton(text: NodeSeq, jsExp: JsExp, func: String = JsCmd,
attrs: (String, String)*): Elem
and not
def ajaxButton(text: NodeSeq, jsFunc: Call, func: () = JsCmd, attrs:
(String, String)*): Elem
jsExp will be called before sending the actual ajax. But this may be a
bit problematic if your jsExp sends the ajaxForm the ajax request is
processed asynchronously at js level meaning the the button ajax
request may be send before the actual ajax form processing is done.
I'm not sure if this fits your needs
Or maybe there is some other, lift-idomatic way to solve my problem?
I want to create a form with a list of elements, with three ajax buttons:
add, remove and save (adding/removing a row and persisting the list)
The first solution I described involving hidden fields will definitely
work. I don't think you need to do 2 ajax calls (one for the form and
one for the button) but piggy back the button information into a
hidden field and only submit the form:
Perhaps something like:
button onclick={(JqId(hidden_field_id) JqAttr(value, add)) +
+ SHtml.submitAjaxForm(form_ID).toJsCmd}blah/button

[Lift] Code generation plugin for SBT
Hi all, I've started a little project to add code-generation to SBT and I would like to hear from anyone who wants to collaborate (and has time to). This could be very important for the lift community, and my aim is to make something like thus: generate lift snippet WhateverName where generate is the sbt plugin command, lift is the library defined in the plugin/project def, snippet is the action/template and WhateverName is the args* that the action or template takes. Im thinking of producing template libraries as JARs and then they could just be distributed via the maven repository system. So, if you want to help out on this, id love to hear from you. If would be an extra bonus if you are an SBT master or have written other plugins as that is where my knowledge is weakest.

[Lift] LiftRules organization
A while ago I started working on having separate parsers and formatters in LiftRules for date, date-time, and time values. These could then be used by Mapped(Date)(Time). I would like to continue working on it, and I would appreciate feedback on the following point. Marius pointed out that it may be a smarter idea, that instead of putting all six variables in LiftRules itself, I should group them together somehow. Here are some possibilities of how to do so. I would appreciate if everyone could vote on one of these ideas or suggest another way. 1. Where? - Put them outside of LiftRules, in a new object called something like FormattingRules - Create an object inside LiftRules, so you would end up writing 'LiftRules.formatRules.formatDateTime ...' - Stick it in TimeHelpers (XXXHelpers are usually not configuration but predefined routines) - Just put it in LiftRules (so what if it just keeps growing) 2. What to call the container - It includes both parsing and formatting, so neither is an accurate name at first glance, but then again parsing is not formatting a a verb but it deals with a particular format - Currently it only deals with java.util.Date, so one could suggest DateRules, but other similar configuration could go here -- formatting numbers? Any other possible future additions? - 'Text' after java.text? - Any good ideas? Thanks! -- You received this message because you are subscribed to the Google Groups Lift group.
