[Lift] Re: Getting Started tutorial - not understanding some syntax
I think the difference is only true in a class body. Inside a code block I
think the def is syntactic sugar for the other syntax.

Viktor, that was a great explanation, im sure ben will apraciate that

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

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 !
Ben

[Lift] Re: User questions
Also I could refactor login to allow programmatic logging in, e.g., def login(email:String, pwd:String):Boolean. Then logInFirst could optionally take an autologin function, which it calls if !loggedIn_?, and then checks loggedIn_? again. This way you can check cookies or IPs etc. and skip the login redirect step by logging in programmatically. Also there has to be a way to record autologin data, like an onLogin function. - Naftoli Gugenheimnaftoli...@gmail.com wrote: Also I could add a method called logInFirst which would return a TestAccess that if the user is logged in returns Empty, and if not sets loginRedirect and returns Full(RedirectResponse(User.loginPageURL)).

[Lift] Re: AJAX form with returned NodeSeq
Sorry my original question was unclear. I'm looking to submit data with the
form, and then get a response back from the server to act on.
The use case is that I have a list of things that I would like to add
elements to on the fly. The desired action is to have the list on the page,
with an add form below it. This form has two text fields, quantity and
item. When submit is clicked, I want to save the contents of those two
fields on the server, and update the displayed list with the new item added.
In other frameworks, the way that I've done this is to have the form
onsubmit contain code that made a jquery ajax call with the contents of the
form, and then would receive the full contents of the new list, which it
would drop into the DOM. Not sure how to rig that up in Lift, though.

[Lift] Re: Wymeditor or FCKEditor
I can't post the whole thing, as it's part of a larger work thing, but
here are the TinyMCE relevant portions:
Boot.scala:
LiftRules.useXhtmlMimeType = false;
ResourceServer.allow {
case tiny_mce::_ = true
}
In my snippet bind:
lift:form method=POST{
bind(block, ns,
text - { (ns: NodeSeq) =
SHtml.textarea(, text = editedText = Box!!text,
currentNode
.map(prefixedElemAttributesToPairs(textarea)).openOr(Nil): _*) },
submit - SHtml.submit(Done, () =
println(got edited block -- + editedText)))
}/lift:form
I expanded the TinyMCE jQuery version into src/main/resources/toserve/
tiny_mce (such that jquery.tinymce.js was in toserve/tiny_mce/
jquery.tinymce.js)
In my template head:
script id=jquery src=/classpath/jquery.js type=text/
javascript/
script id=jquery src=/classpath/jquery-ui/js/jquery-
ui.js type=text/javascript/
script id=jquery_tiny_mce type=text/javascript src=/
classpath/tiny_mce/jquery.tinymce.js /
script id=tiny_mce type=text/javascript src=/
classpath/tiny_mce/tiny_mce.js /
(I load both to have it warm up the load to tiny_mce.js, otherwise
jquery.tinymce.js loads it and it lags the UI a bit. I use jQuery UI,
and in particular my TinyMCE instance shows up in a jQuery dialog,
although this shouldn't affect the overall behavior)
In my template body:
div id=emailwizard-edit-block-dialog
edit:blockEditForm
block:text textarea:id=emailwizard-edit-block-
textarea textarea:style=width: 100%; height: 100%; /
/edit:blockEditForm
/div
(edit:blockEditForm is a sub-bind of another snippet)
In my javascript file for the page:
/* Handle editing a block by popping the edit box and
initializing TinyMCE */
function handleBlockEdit(target)
{
function finishTinyMCESetup()
{
var editor = $(#emailwizard-edit-block-
textarea).tinymce();
editor.focus();
editor.setContent(/* prefill content */);
editor.save();
$(#emailwizard-edit-block-dialog).dialog(enable);
}
$(#emailwizard-edit-block-dialog)
.data(target, target)
.dialog(open)
.dialog(disable);
$(#emailwizard-edit-block-textarea)
.tinymce({ script_url: /classpath/tiny_mce/tiny_mce.js,
// various configuration of the TinyMCE
omitted for brevity -- none is really relevant to general integration
init_instance_callback: finishTinyMCESetup });
}
$(document).ready(function() {
$(#emailwizard-edit-block-dialog)
.dialog({ autoOpen: false,
bgiframe: true,
beforeclose: handleBlockDialogClose,
buttons: { Done: handleBlockSubmit },
modal: true,
resizable: false,
title: Edit Block,
width: 600,
height: 308 })
.css(padding, 0);
});
There is a separate button whose click handler calls handleBlockEdit
to pop the dialog and initialize TinyMCE. The bit about enabling and
disabling the dialog is to make the dialog gray while TinyMCE replaces
the textarea with its own stuff.
Note that I have not gotten the AJAXing of the edited content back to
the server working, so the bit about the AJAX enabled textarea could
very well be totally wrong.
I think in general the only sticking points are that you can't use
XHTML MIME type (as others mentioned on thread) as TinyMCE will want
to use document.write.
Hopefully the fact that this is extracted from a larger project isn't
too confusing and that this helps.

[Lift] Re: Jersey + Lift, whats the story?
On Jul 30, 2009, at 7:57 PM, David Pollak wrote:
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.
On the Jersey side of things there are a bunch of paths that are known
statically at deployment time and can be obtained either from the
internal WADL or the abstract model of the root resource classes,
those classes annotated with @Path. The stuff declared in @Path
represent the entry points into the JAX-RS/Jersey application.
Path matching can also occur dynamically and is determined by the
annotations on the resource returned by a method annotated with @Path,
for example:
@Path(customer)
public Object getSubResource() {
if (/ preferred customer/) {
return new PreferredCustomer(); // additional sub-resources for
preferred customers
} else {
return new Customer();
}
}
Not sure if the above is relevant/important or not w.r.t. SiteMap. It
might be if Lift templates are utilized.
Paul.
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.
It would certainly be useful to reuse Lift's Menu rendering when using
a Lift template to render a JAXRS resource bean; am sure that would
not be too hard to fix. We might want to support adding resource beans
to the menus too

[Lift] Re: JSON form with
I have had a look at the change, while better than the old one it
still causes problems if you use a in a text box because you are
building JSON as a string and then parsing it.
In my example code you go from a javascript object to another one
there is no need for parsing so you don't run into problems with
escape characters.
I don't know if you are building the JSON as a string then parsing it
for compatibility reasons if so you should escape any found in the
name and value.
e.g.
json += \ + e.name.replace(/\/g,\\\) + \:\ + e.value.replace
(/\/g,\\\) + \,;

not operate on the JSON from jQuery from the start.
e.g.

This does work differently from before since it won't call functions

functions in the object it returns so that is not needed.

[Lift] Re: How to use Mapper and record framework
Hi Giuseppe,
Thanks for u r valuable support.i got the flavor of this framework.
I did one POC(sample application) with MySQL ...and its worked very
smoothly.
Is Lift provides support for MS SQL.?
Now i am using same thing with MS SQL but i am getting following
error :-
Message: com.microsoft.sqlserver.jdbc.SQLServerException: Invalid
column name 'id'.

(Unknown Source)
com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(Unknown

..
In my application i am just reading table content with findAll method.
in my table i have only two fields - EmpId, EmpName
i checked all things but didnt get any clue
In short -
Is lift's mapper framework provides Support for MS SQL ?
Thanks

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.

[Lift] Re: how 10 seconds works?
Implicit conversions. In TimeHelpers.scala we have: 1. TimeSpanBuilder which contains method minutes, seconds etc. 2. And the implicits such as: implicit def intToTimeSpanBuilder(in: Int): TimeSpanBuilder = TimeSpanBuilder(in) therefore compiler automatically applies intToTimeSpanBuilder (10).seconds as the type of object 10 has no minutes method. So 10 minutes will yield a TimeSpan instance. Still you can use (3 + (10 seconds)) because there is another implicit conversion implicit def timeSpanToLong(in: TimeSpan): Long = in.millis to convert from a TimeSpan to a Long hence (10 minutes) can be used in arithmetic operations.

[Lift] Submit like SHtml.text but with ajaxText
I'm looking for some guidance on how best to have the value of text
field that's been ajax-ified picked up on a regular submit.
What I mean is:
If I have a field of
object word extends RequestVar()
which I bind like this
bind(f, xhtml,
word - SHtml.text(word,word(_)),
submit - SHtml.submit(GO, processForm)
)
and everything is lovely and this does what you expect:
def processForm() = {
Log.info(Submit from the form:)
Log.info(word)
}
Now I want to add some dynamic feedback for the user of the form so I
switch to...
word - SHtml.ajaxText(word, checkWord(_))
with
def checkWord(w:String) = {
Log.info(Ajax check: +w)
Noop
}
That also works just great. But when the submit button is hit, of
course there's now no-longer the assignment into word RequestVar
anymore. And I'd like there to be (regardless of if the Ajax
checkWords is ever called or not).
So where should I be looking to insert the word(_) call to get the
AJAX goodness but also the good old submit behaviour?
My current thinking is that I use a SHtml.text but then mess with the
input that's created to include the appropriate Ajax calls I want.

On Thu, Jul 30, 2009 at 8:29 PM, Avo Reid avor...@cox.net wrote: So I can't use text/html or use java components that write to the DOM, except for JQuery? No. Who ever said that? Lift *by default* serves content as application/xhtml+xml. You can change the behavior as another post in this thread points out. There is a downside to changing the mime type of served pages to text/html... the browsers go into a less well defined mode for rendering the pages. application/xhtml+xml is very well defined and I've only seen on very small cross browser rendering difference in the nearly 3 years of using XHTML. This is not true of the tag soup mode that browsers go into with text/html. The downside of using application/xhtml+xml is that certain non-standard (but broadly implemented) DOM manipulation methods are not supported. One of these is to open an DOM element and do a write to that DOM element. You may use innerHTML and other mechanisms to morph the DOM in XHTML mode. This is an XHTML thing. It is not a Lift thing. But it is a by-product of being in XHTML mode. Some JavaScript libraries use DOM write (once again, this is a single method that allows you to treat a DOM element like a stream and write characters into it.) These libraries will not work on any page that is served with the application/xhtml+xml mime type from any web server, from any web framework. This has nothing to do with Lift, this has to do with the browsers and the standards. The error is the neither wymeditor or fckeditor work with Lift. Let's make things simple, shouldn't it be possible to simply add a wymeditor to the default html of the hello world example and have it render correctly? I'm going to make it simple. You have come into this community and asked for help. We try to be very welcoming to newbies and to try to help people out with issues. The particular issue, mime type application/xhtml+xml vs. text/html, has been discussed numerous times in the last few months. But rather than saying RTFM or some other thing that could chase a newbie away, I asked that you work with me to diagnose the issue. Now, why is it better to diagnose the issue? First, if there is a problem in the external library (e.g., not being XHTML compatible), then we can take this information to the authors of the library and work with them to resolve the issue. We have done that in the past with issues... including an XHTML namespace issue that causes problems with jQuery on Firefox. But coming to the discussion armed with all the facts helps make the discussion smooth. The second reason to diagnose the issue is to give you and the whole community a deeper understanding of the issue and that allows more effective diagnosis of similar issues in the future. This builds institutional knowledge. So, if you want to work with me to diagnose the issue, I'm still here and willing to work with you. If you want to set the default rendering type to text/html it will likely solve your issue. If you want to continue to claim that there's some problem with Lift, you can be on your way. Lift simply generates the XHTML that you tell it to and returns that XHTML to the browser with with certain headers set by default, but that can be changed by your code. If there's something that's not rendering correctly in the browser and you've sent down proper XHTML, then talk to the library or browser maker rather than claiming that Lift isn't doing something correctly.

You need to put all the wymeditor js files in a source/main/resources/
toserve directory.
Then I create a snippet:
def onInit(xhtml: NodeSeq):NodeSeq =
head
script type=text/javascript src={/ +
LiftRules.resourceServerPath + /wymeditor/jquery.wymeditor.pack.js}
/script
script type=text/javascript charset=utf-8{
Unparsed(
jQuery(document).ready(function() {
jQuery('.wymeditor').wymeditor();
})
)
}
/script
/head
which i run in Boot.scala.
Then, in a bind helper, use something like
bind(content, xhtml,
...
description = textarea(loadHtml(currentContent.link.is).toString,
page(_), (class, wymeditor)),
...)
Does that help?
Glenn...

[Lift] Re: Wymeditor or FCKEditor
David, My apologies, I didn't mean to communicate that there is something wrong with Lift, I am very interested in Lift and have a great deal of respect for what you have accomplished here. My question about making things simple was frankly to clarify whether it was possible to drop in a java component like wymeditor or fckeditor, in an effort to get a long term view of the LOE on putting together a commercial web app with multiple 3rd party components. I understand the XHTML issue and I have learned a lot from the posts here to understand the answer to that question and how it can be done with Lift. I am going to implement these concepts and will get back to you with my findings on the different components and hopefully get them integrated the right way. Thanks for your time and patience, Avo The error is the neither wymeditor or fckeditor work with Lift. Let's make things simple, shouldn't it be possible to simply add a wymeditor to the default html of the hello world example and have it render correctly?

No. Who ever said that? Lift *by default* serves content as application/xhtml+xml. You can change the behavior as another post in this thread points out. There is a downside to changing the mime type of served pages to text/html... the browsers go into a less well defined mode for rendering the pages. application/xhtml+xml is very well defined and I've only seen on very small cross browser rendering difference in the nearly 3 years of using XHTML. This is not true of the tag soup mode that browsers go into with text/html. The downside of using application/xhtml+xml is that certain non-standard (but broadly implemented) DOM manipulation methods are not supported. One of these is to open an DOM element and do a write to that DOM element. You may use innerHTML and other mechanisms to morph the DOM in XHTML mode. This is an XHTML thing. It is not a Lift thing. But it is a by-product of being in XHTML mode. Some JavaScript libraries use DOM write (once again, this is a single method that allows you to treat a DOM element like a stream and write characters into it.) These libraries will not work on any page that is served with the application/xhtml+xml mime type from any web server, from any web framework. This has nothing to do with Lift, this has to do with the browsers and the standards. The error is the neither wymeditor or fckeditor work with Lift. Let's make things simple, shouldn't it be possible to simply add a wymeditor to the default html of the hello world example and have it render correctly? I'm going to make it simple. You have come into this community and asked for help. We try to be very welcoming to newbies and to try to help people out with issues. The particular issue, mime type application/xhtml+xml vs. text/html, has been discussed numerous times in the last few months. But rather than saying RTFM or some other thing that could chase a newbie away, I asked that you work with me to diagnose the issue. Now, why is it better to diagnose the issue? First, if there is a problem in the external library (e.g., not being XHTML compatible), then we can take this information to the authors of the library and work with them to resolve the issue. We have done that in the past with issues... including an XHTML namespace issue that causes problems with jQuery on Firefox. But coming to the discussion armed with all the facts helps make the discussion smooth. The second reason to diagnose the issue is to give you and the whole community a deeper understanding of the issue and that allows more effective diagnosis of similar issues in the future. This builds institutional knowledge. So, if you want to work with me to diagnose the issue, I'm still here and willing to work with you. If you want to set the default rendering type to text/html it will likely solve your issue. If you want to continue to claim that there's some problem with Lift, you can be on your way. Lift simply generates the XHTML that you tell it to and returns that XHTML to the browser with with certain headers set by default, but that can be changed by your code. If there's something that's not rendering correctly in the browser and you've sent down proper XHTML, then talk to the library or browser maker rather than claiming that Lift isn't doing something correctly. Thanks, David On Jul 30, 11:10 pm, David Pollak feeder.of.the.be...@gmail.com wrote: Lift, by default, serves with a mime type of application/xhtml+xml (except to IE).

This does work differently from before since it won't call functions

[Lift] Re: Implementing KeyedRecord[T,K]
To my understanding, KeyedRecord as well as KeyedField should provide the basis to implement relationship between model objects. If in my model object I have a relationship with another model object this will required the referred class to be at least a KeyedRecord. Such ReferenceField similar to the MappedForeignKey in Mapper, will have the same basic type of the KeyField in the referred KeyedRecord. Unfortunately in order to complete the design of a ReferenceField, it is required a getInstance or find method to load the object corresponding to the key. Implementation of this method is strictly related to the persistence backend but a generic definition should be inserted in MetaRecord (or better KeyedMetaRecord). Situation is even more complicated when yu have hierarchical (one to many) or even many to many relationship. I am studying sources from the recent addition to Mapper to get inspiration. In the ongoing jsr-170 backend to Record this is the way I am following even if after many redesigns some docs and support from the community on how to implements custom record backedn would be more than welcome.

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

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
}
Lift is XHTML. The above will not work in XHTML because the code will be
escaped into XML.
Try the following:
def update(in: NodeSeq): NodeSeq = Script(JsRaw(
loc.onUpdate = function(lat, lon) {
+SHtml.ajaxCall(JsObj(lat - JsVar(lat), lon -
JsVar(lon)), updatePosition _)._2.toJsCmd+
};
))
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)
I'm committing up jsonCall which augments ajaxCall by serializing
(JSON.stringify) the expression before sending it to the server and then
JSON parsing on the server before sending it to your function.
Thanks. Wow, this really makes AJAX development something I'd actually
enjoy doing. :)

Sorry my original question was unclear. I'm looking to submit data with the
form, and then get a response back from the server to act on.
The use case is that I have a list of things that I would like to add
elements to on the fly. The desired action is to have the list on the page,
with an add form below it. This form has two text fields, quantity and
item. When submit is clicked, I want to save the contents of those two
fields on the server, and update the displayed list with the new item added.
In other frameworks, the way that I've done this is to have the form
onsubmit contain code that made a jquery ajax call with the contents of the
form, and then would receive the full contents of the new list, which it
would drop into the DOM. Not sure how to rig that up in Lift, though.
The To Do example in Getting Started has an example of doing this. See

Don't know about scaladoc, but there was a bug in older maven versions about offline usage. What version do you have?

Maven is a bit tricky when trying to go offline if you have snapshot dependencies. Having said that... I've definitely not been bitten by the issue since upgrading to 2.2 - so you really want to check you're on the latest version, as it looks like they've recently done a lot of releases in quick succession, On Fri, Jul 31, 2009 at 9:54 PM, David Pollak feeder.of.the.be...@gmail.com wrote: Grant, Are you on Windows or OS X?

[Lift] Re: New features
Naftoli,
I set up my mapper to use your new ManyToMany trait, but I'm not sure
how exactly to use it in a snippet or view.
Here's what I have so far, a User, Role and UserRole for my model
classes:
class Role extends LongKeyedMapper[Role] with IdPK {
def getSingleton = Role
object name extends MappedPoliteString(this, 50) {
override def setFilter = notNull _ :: trim _ :: super.setFilter
}
}
class UserRole extends LongKeyedMapper[UserRole] with IdPK {
def getSingleton = UserRole
object role extends MappedLongForeignKey(this, Role){
override def dbIndexed_? = true
}
object user extends MappedLongForeignKey(this,User) {
override def dbIndexed_? = true
}
}
class User extends MegaProtoUser[User] with ManyToMany[UserRole, Role]
{
def getSingleton = User // what's the meta server
// define an additional field for a personal essay
object textArea extends MappedTextarea(this, 2048) {
override def textareaRows = 10
override def textareaCols = 50
override def displayName = Personal Essay
}
object role extends MappedManyToMany(UserRole, this, Role)
}
and their corresponding singleton objects.
In the past, without the ManyToMany trait, I would do this in User
object
override def editXhtml(user: User) = {
(form method=post action={S.uri}
tabletrtd colspan=2{S.??(edit)}/td/tr
{localForm(user, true)}
trtdRoles/tdtduser:roles//td/tr
trtdnbsp;/tdtduser:submit//td/tr
trtda href={changePasswordPath.mkString(/, /,
)}
{S.??(change.password)}/a/td/tr
/table
/form)
}
and bind this with the following to show the roles for a particular
user as a comma delimited string.
def innerEdit = User.isa_?(admin) match {
case true = bind(user, editXhtml(theUser),
roles - text(roles,
doRolesAndSubmit),
submit - SHtml.submit(S.??(edit),
testEdit _))
case false = bind(user, editXhtml(theUser),
roles -
theUser.showRoles,
submit - SHtml.submit(S.??(edit),
testEdit _))
}
here roles is defined as
var roles = theUser.roles.map(_.name.is).mkString(, )
Do you have an example of how to achieve something similar with your
new ManyToMany and MappedManyToMany code?
Appreciate any help you can give me.

To use many-to-many, simply mix ManyToMany to your mapper, then create a
MappedManyToMany field like any other field. See the scaladocs for
specifics.
Then in your view you can use the field like a collection, e.g., remove an
element with -=, and save the mapper to apply the changes.

But, then I have to add code like this to the meta-mapper objects:
def addTags(entry: Content) {
if(entry._tags ne null){
entry._tags.foreach(ContentTag.join(_, entry))
}
}
def delTags(entry:Content) =
ContentTag.findAll(By(ContentTag.content, entry)).foreach
(_.delete_!)
It's not very pretty. Nor easy to duplicate.
I hope your new code is considerably less messy.

[Lift] Re: Submit like SHtml.text but with ajaxText
I just committed code that allows:
bind(form, xhtml,
first - text(firstName, firstName = _, s = {S.notice(First
name +s); Noop}),
last - text(lastName, lastName = _, s = {S.notice(Last name

submit - submit(Send, validate _))
You can have an onblur associated with a server-side function.

I'm looking for some guidance on how best to have the value of text
field that's been ajax-ified picked up on a regular submit.
What I mean is:
If I have a field of
object word extends RequestVar()
which I bind like this
bind(f, xhtml,
word - SHtml.text(word,word(_)),
submit - SHtml.submit(GO, processForm)
)
and everything is lovely and this does what you expect:
def processForm() = {
Log.info(Submit from the form:)
Log.info(word)
}
Now I want to add some dynamic feedback for the user of the form so I
switch to...
word - SHtml.ajaxText(word, checkWord(_))
with
def checkWord(w:String) = {
Log.info(Ajax check: +w)
Noop
}
That also works just great. But when the submit button is hit, of
course there's now no-longer the assignment into word RequestVar
anymore. And I'd like there to be (regardless of if the Ajax
checkWords is ever called or not).
So where should I be looking to insert the word(_) call to get the
AJAX goodness but also the good old submit behaviour?
My current thinking is that I use a SHtml.text but then mess with the
input that's created to include the appropriate Ajax calls I want.

[Lift] Re: New features
I didn't yet look at your code too closely, but the idea is that the field
that represents the relationship implements Buffer, so you can add, remove, and
iterate its elements, which are the other side of the relationship. These
changes are remembered until you call save, when they are acted on.

Naftoli,
I set up my mapper to use your new ManyToMany trait, but I'm not sure
how exactly to use it in a snippet or view.
Here's what I have so far, a User, Role and UserRole for my model
classes:
class Role extends LongKeyedMapper[Role] with IdPK {
def getSingleton = Role
object name extends MappedPoliteString(this, 50) {
override def setFilter = notNull _ :: trim _ :: super.setFilter
}
}
class UserRole extends LongKeyedMapper[UserRole] with IdPK {
def getSingleton = UserRole
object role extends MappedLongForeignKey(this, Role){
override def dbIndexed_? = true
}
object user extends MappedLongForeignKey(this,User) {
override def dbIndexed_? = true
}
}
class User extends MegaProtoUser[User] with ManyToMany[UserRole, Role]
{
def getSingleton = User // what's the meta server
// define an additional field for a personal essay
object textArea extends MappedTextarea(this, 2048) {
override def textareaRows = 10
override def textareaCols = 50
override def displayName = Personal Essay
}
object role extends MappedManyToMany(UserRole, this, Role)
}
and their corresponding singleton objects.
In the past, without the ManyToMany trait, I would do this in User
object
override def editXhtml(user: User) = {
(form method=post action={S.uri}
tabletrtd colspan=2{S.??(edit)}/td/tr
{localForm(user, true)}
trtdRoles/tdtduser:roles//td/tr
trtdnbsp;/tdtduser:submit//td/tr
trtda href={changePasswordPath.mkString(/, /,
)}
{S.??(change.password)}/a/td/tr
/table
/form)
}
and bind this with the following to show the roles for a particular
user as a comma delimited string.
def innerEdit = User.isa_?(admin) match {
case true = bind(user, editXhtml(theUser),
roles - text(roles,
doRolesAndSubmit),
submit - SHtml.submit(S.??(edit),
testEdit _))
case false = bind(user, editXhtml(theUser),
roles -
theUser.showRoles,
submit - SHtml.submit(S.??(edit),
testEdit _))
}
here roles is defined as
var roles = theUser.roles.map(_.name.is).mkString(, )
Do you have an example of how to achieve something similar with your
new ManyToMany and MappedManyToMany code?
Appreciate any help you can give me.

Grant, If your on windows or OSX, just take a look at your $M2 environment variable and remove the javarebel path... We didn¹t know at the time of making that installer that it would expire in one year if we had, we probably would have thought twice about enabling it. That¹s another story... Anyway if you don¹t know how to alter the environment var, just search your system for javarebel.jar and delete it; that will certainly remove the problem. Sorry for the confusion. Regarding building documentation offline, if you have a version of maven earlier than 2.2, you¹ll need to run: mvn install scala:doc However if you have 2.2+ then you can just do: nvn scala:doc Cheers Tim On 31/07/2009 22:06, Kevin Wright kev.lee.wri...@googlemail.com wrote: Maven is a bit tricky when trying to go offline if you have snapshot dependencies.

[Lift] Re: Hudson failing again and Lift build failure
It's two issues - one is that we have busted code in the lift code

it)... The other issue is the Hudson box; before the DoS attack we had
no problems at all so that to me says it's something different now
than compared to before that's causing all these open file handles.

[Lift] Re: Hudson failing again and Lift build failure

I've fixed the broken build.
Josh will be upgrading Hudson (and perhaps adding a cron job to restart it
daily)
