[Lift] Re: Anyone working on the flot widget?
Hi flot users, I am trying to copy the basic Flot example into my own code. I have no compile errors but the graph isn't rendered because /classpath/flot/ jquery.flot.js isn't found. Since I get no errors with the flot methods in my snippet, I assume lift-widgets is loading correctly. Am I missing something?

They should be used in AJAX and Comet applications - update to a more recent version of the javascrrit widget I need this as well, especially since there are some patches that provides pie charts - create the test demo app, - make the creation of FlotOptions, FlotLinesOptions, etc, less verbose. I hope that Scala 2.8 Named and Default Arguments will help. Yeah, this would be nice :-) We probably need some working code within the next few weeks so probably can't wait for 2.8 though. - create a high level mechanism to display Lift's Record I appreciate any help.

[Lift] Error attempting to persist Mapper
Hi all,
I'm attempting to persist a Mapper used to join two tables.
java.lang.NullPointerException: Trying to open an empty Box
at net.liftweb.util.EmptyBox.open_$bang(Box.scala:370)
at net.liftweb.util.EmptyBox.open_$bang(Box.scala:366)
at net.liftweb.mapper.MetaMapper$$anonfun$12.apply(MetaMapper.scala:
583)
at net.liftweb.mapper.MetaMapper$$anonfun$12.apply(MetaMapper.scala:
578)
at net.liftweb.mapper.DB$.use(DB.scala:305)
at net.liftweb.mapper.MetaMapper$class.save(MetaMapper.scala:577)
The empty box is in the update statement, which confuses me as I
should be performing an insert.( from MetaMapper )
val ret: Boolean = DB.prepareStatement(UPDATE
+dbTableName+ SET +whatToSet(toSave)+ WHERE +indexMap.open_! +
= ?, conn)
I am assuming it is something to do with my understand of how to use a
non-keyed Mapper.
The exception is thrown when save is called in the join function.
class AB extends Mapper[AB] {
def getSingleton = AB
object A extends MappedLongForeignKey(this, A) { override def
dbColumnName = a_Bs_id }
object B extends MappedLongForeignKey(this, B) { override def
dbColumnName = B_id }
object index extends MappedInt(this) { override def dbColumnName =
Bs_idx }
}
object AB extends AB with MetaMapper[AB]
{
override def dbTableName = A_B
def join (a : A, b : B):Boolean = {
val list = AB.findAll(By(AB.a,a))
val i = list.isEmpty match {
case true = 0
case false = list.size
}
this.create.A(a).B(b).index(i).save
}
}
Any pointers would be appreciated, I can't change the data structure
as the table is used by other applications.
Jono

[Lift] Re: New mapper class: MappedEnumString
Oliver Lambert olambo...@gmail.com writes:
[...]
No this isn't what I'm suggesting, I don't think MappedEnum should be made
flexible.
I know this wasn't your suggestion, but any reason not to make
MappedEnum flexible (if possible and backwards compatibility could be
maintained) ?
I was thinking perhaps your class could work with EnumWithDescription
as shown below, which extends Enumeration#Values to include a
description.
This should be simple, but see below
trait ValueWithDescription {
def description: String
def name: String
}
abstract class EnumWithDescription {
type Value = enum.Value with ValueWithDescription
private var _values: List[Value] = Nil
def values = _values
// possibly not a good idea using this directly
val enum = new Enumeration {
def Value(inName: String, inDescription: String): Value with
ValueWithDescription = {
new Val(nextId, inName) with ValueWithDescription {
def description = inDescription
def name = inName
}
}
}
def Value(name: String, description: String): Value = {
val value = enum.Value(name, description)
_values = _values ::: List(value) // build in order
value
}
def Value(name: String): Value = Value(name, name)
def valueOf(name: String) = values find (_.name == name)
def nameDescriptionList = values map(x = (x.name, x.description) )
}
At first I didn't understand why you don't just extend Enumeration like
this:
abstract class EnumWithDescription extends Enumeration {
def Value(inName: String, inDescription: String): Value with
ValueWithDescription = {
new Val(nextId, inName) with ValueWithDescription {
def description = inDescription
def name = inName
}
}
}
but figure you would then have to cast all the values to
ValueWithDescription. It seems Enumeration miss a type parameter to
describe the types of Values in cases like this. Hmmm I see Enumerations
have changed for 2.8 so maybe this is not impossible
Back to the mapping. The way I see all these different solutions is:
1) We need to define Enumerations to get nice handling of predefined
constants
2) The enumeration values need to be mapped to a database value (numeric
or string)
3) The enumeration values need to be mapped to a display value (from
code our property files)
If the MappedEnum was parameterized on how to achieve 2+3 it seem all
possibilities are open. If MappedEnum worked with ValueWithDescription
values instead of Enumeration#Value, it might? be possible to define an
implicit conversion from Enumeration#Value to ValueWithDescription
I don't have much time in the days that are coming but will try to think
of a solution to this. Input is welcome :-)

[Lift] Re: Anyone working on the flot widget?
Thanks, Jeppe, that's what I was missing. To continue to hijack this thread with my own questions, I'm having a problem creating the data List[(Double, Double)] that FlotSerie wants. I have: override val data = MyModel.findAll(By(MyMode.id, myId), OrderBy (MyModel.datetime, Ascending)).map(m = (m.datetime.getTime.toDouble, m.temperature.toDouble)) This gives me an error saying I'm missing arguments for toDouble in class MappedDouble (this is MyModel.temperature) and suggests treating it as a partially applied function. I'm not sure I want to do that but, trying it anyway (with m.temperature.toDouble _), I got an new error saying that List[(Double, (Any) = Double)] is an incompatible type. Any suggestions?

The problem here is actually not with mapper. Look at your stack

Whatever indexMap is, its of type Empty rather than Full[YourType] -
try this:
UPDATE +dbTableName+ SET +whatToSet(toSave)+ WHERE
+indexMap.openOr(yourDefault) + = ?
Essentially, your getting an NPE because your trying to read something
that doesn't exist. Using openOr will make sure that if the box is
empty your default value is used in its place rather than exploding
like that.
Does that help?

[Lift] Warnings for missing binds?
I just spent the better part of half a day trying to track down an issue with binding that ended up being a subtle typo. I'm thinking of adding in some logging (in dev mode) for the bind function to warn about unused bind elements and unused bind params, just to better help locate issues like this. Any objections?

Jono,
The problem here is actually not with mapper. Look at your stack

Whatever indexMap is, its of type Empty rather than Full[YourType] -
try this:
UPDATE +dbTableName+ SET +whatToSet(toSave)+ WHERE
+indexMap.openOr(yourDefault) + = ?
Essentially, your getting an NPE because your trying to read something
that doesn't exist. Using openOr will make sure that if the box is
empty your default value is used in its place rather than exploding
like that.
Does that help?

I am assuming it is something to do with my understand of how to use a

The exception is thrown when save is called in the join function.

Can I give some general encouragement to people to use the bug database to report bugs rather than sending them to the lists, unless there is something super unusual and fascinating about that particular bug, keeping in mind there are hundreds of open tickets which should be no less important for being a little (or a lot) older. -- Paul Phillips | Where there's smoke, there's mirrors!

[Lift] Re: Anyone working on the flot widget?
Hello everyone involved, I am having a very annoying problem with the Flot widget: The automatically generated legend's auto-sizing feature is broken (it grows horizontally to the max allowed space while still adhering to the margin values specified, and it's not possible to create an external, custom legend) as demonstrated by this screenshot: http://bit.ly/uKE9o This bug is present in 1.1-M1 as well as 1.1-SNAPSHOT, isn't caused by me (since it is present int he demo app) and seems to originate from something on the client-side (obviously). Does anyone have a solution to this problem, or if not, can I make a fork of the widgets module, try to fix the problem, and commit it back? This little inconvenience removes much of the visual quality of plots, so a solution to it would be very much appreciated. /dflemstr On Jun 25, 2:13 pm, Jeppe Nejsum Madsen je...@ingolfs.dk wrote: On 25 Jun 2009, Francois Bertrand wrote: Hi Jeppe Great to see you are interested in the flot widget. My current to-do list for the flot widget, is: - create more Lift JsExp and JsCmd to modify a already displayed flot graph. They should be used in AJAX and Comet applications - update to a more recent version of the javascrrit widget I need this as well, especially since there are some patches that provides pie charts - create the test demo app, - make the creation of FlotOptions, FlotLinesOptions, etc, less verbose. I hope that Scala 2.8 Named and Default Arguments will help. Yeah, this would be nice :-) We probably need some working code within the next few weeks so probably can't wait for 2.8 though. - create a high level mechanism to display Lift's Record I appreciate any help. What's the best way to coordinate this? Just fork the code on github or? /Jeppe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Turning on Logging for third-party libraries in Lift
I'm trying to enable log4j logging in a third party library (well third party to me.. it was developed in house) so that it logs it's output to the same place my Lift webapp logs. In the third party library, a log4j Logger is obtained and used but no setup is done, figuring the log4j config will be done by the app builder. Now I figured the root logger would catch it.. but it didn't seem to work. So I added a specific logger with the exact string used in the third party code.. Still no output.. Am I missing something about class loaders? Or is there something about start-up that's messing with the getLogger method (it's actually in the method so it should be happening after Lift initializes everything)? Or is there something else special about lift logging that won't let the library piggy back off of it? BTW, I should mention that Lift logging otherwise is working for me. By otherwise I mean when logging from any classes directly in the web- app classes directory.

[Lift] Re: Getting Username and Password from URL of form hxxp://user:passw...@foo.org
Problem solved! I knew how to get and decode the header style.. it's the http://username:passw...@foo.org that I couldn't get to. I didn't see how to get the string that contains the username and password in this case. I found it though.. if you get the HTTPServletRequest and then the URL from that has the complete string. Oh and for various reasons I can't use the built in authentication stuff.

If not, please see my example here:http://is.gd/1cYhR The format you mention is standard HTTP Basic, and in accordance with the RFC's - it should be Base64 encoded. Lift supports both HTTP basic and HTTP digest. Cheers, Tim On Jun 25, 5:10 am, Alan M alan.morten...@gmail.com wrote: I can't seem to find anyway to get to those two values. I've been searching all over the request class/object and no luck. I'm writing a RESTful web service that uses basic auth and for some reason jQuery likes to send things in the above mentioned format (http://user:passw...@foo.org). I've tried to fix that on the Javascript side but I couldn't get anything to work. So instead I decided on the service to recognize either the header style or the URL style of passing the login info. Sounded simple enough, until I couldn't find how to get at that/those strings.. Any help would be greatly appreciated..

[Lift] suggestion: I'm a brand spanking new user....some first impressions on 'getting started'
Today is my very first day that I planned to take a serious look at Lift. I've coded webapps in many different frameworks and plan to do a simple Employee app and add my 'how to' to the site I host here http://www.learntechnology.net/content/main.jsp (which many of the examples there show the same application being built with different frameworks.) Some users like myself might want to start by looking at an existing examples before going through the exact step by step as described in the user manual (which has a broken link to the wiki by the way -yes, I submitted a bug report.) If I want to take that route there should be a quick way to find example projects with the source code. Finding these example was extremely tedious At some point a new user might go the wiki. .. you get to the wiki page looking for examples.. you look at the content menu.. you might try the 'cheat sheet getting started link'... cheat by examples has a link 'lift by examples', but that doesn't seem to really show example apps? BY CHANCE, I happened to see in a How To - how to run examples (which at first i thought why would I click this when I haven't even seen any examples?), but I clicked it anyway.. Then on the how to run examples' link I was excited to see a list of some examples (buried way to deep for a new user to find imo.) Yet only the war links work? None of the project links are active? Finding example apps to study and learn by is seemingly very difficult to do. Are there any out there? If so where? For new user, learning by examples is extremely important. I think a lot of new users will be turned off if it's difficult to find some example applications to study to learn from. I understand all of this is open source and I plan to write a tutorial once I learn it, but it would be nice to find some existing apps to start with. thanks for all the work done so far. -- Rick R --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Modify CRUDify XHTML
Thanks, Derek and Jeppe, your responses were very helpful. I
implemented Jeppe's solution and added my own snippet tag within
_viewTemplate. Unfortunately, I spent the whole day trying to figure
out how pass the current CRUDified object to my snippet. Do I retrieve
it in _viewTemplate from S.params and add an attribute to the snippet
tag? Or just retrieve it from S in the snippet? I think I'm missing
something fundamental with the S object and snippets. As you can tell,
I'm very new to Lift! Any advice is much appreciated.

Hi all,
I'm using CRUDify on one of my models and I'd like to display some
additional data on the view template. I believe that I need to
override one of the model definitions with some sort of reference to
my own XHTML file. Which one? _viewTemplate? Or perhaps the
viewTemplate method?
If you look at the source to CRUDify, you'll see
def viewTemplate(): NodeSeq = pageWrapper(_viewTemplate)
where
def pageWrapper(body: NodeSeq): NodeSeq =
lift:surround with=default at=content
{
body
}
/lift:surround
def _viewTemplate =
lift:crud.view
table id={viewId} class={viewClass}
crud:row
tr
tdcrud:name//td
tdcrud:value//td
/tr
/crud:row
/table
/lift:crud.view
So the simplest thing is to override _viewTemplate with something similar
to the above. This should be done on the companion objects where CRUDify
is mixed in
