[Lift] Re: error while SHtml.ajaxInvoke call

2009-08-24 Thread pravin

hi,
its former method i am using in my app(u mentioned it in last reply).

i have one text box and submit button.

when i click on submit button -
i have to show employee info on my GUI page.  (in text box i will
enter emp Id))

This info have to table
one table have information with ajax and other have info with normal
call.

how can i populate these two table when i click on submit button...


hope this will help u to understand my problem.


Thanks...

waiting for u reply

 I still don't understand.

 Does the user do anything to get the faster table updated or do you want the
 faster table pushed from the server when something changes on the server?

 If it's the former (the user does something to get the faster table
 updated), you want to use ajaxButton... the user clicks on the button and
 the server-responds with JavaScript that updates the browser.

 If it's the latter (the user does nothing, but the server pushes changes to
 the client), see CometActor.  You can see an example in the Clock.scala code
 in the Lift sites/example project.

  Hi,
  Thanks for u r quick reply.
  Now I am explain my problem in details :

  I have normal form with one text box and one submit button.

  Also i have 2 table components(these are dynamic tables )..but these
  table are out of the from tag.These table only displays information.

  Flow of the application:

  When i click on submit button.
  i am population two Lists .

      One list get populated from DB.( Slower)
      second list get populated from hard code values (faster)

  Now i am populate above 2 tables with these two lists when i click on
  submit button.

  With the above flow i am able to populate above tables(synchronously).

  But now i want to configure Ajax into this so i can get faster
  results...(as one List get faster)
  while other list can get populated asynchronously.

  So when i click on Submit button i will populate one list ..but how
  can i populate other list with Ajax...

  i tried for following:
  i was planning when other table getting render  make ajax call with
  ajaxInvokebut i wont work...

  Please help ...

  Thanks in advance

yes i have submit button.
on click event of this i am doing other tasks.

   What is the user interface (HTML) element that causes the Ajax update to
   happen?  What does the user do in order to get the Ajax thing to happen?

   ajaxInvoke is a very low level call.  If you want to have an Ajax button,
   use SHtml.ajaxButton.  If you want to have an Ajax form, use
  SHtml.ajaxForm.
    If you can describe what the user interaction should be, I'll write up
  some
   example code for you.

above data population for text is not on click submit button.

Hmmm .. I'm wondering if we can write a Scala compiler plugin that
transform functions provided to Lift's S/SHtml function etc. into a
richer FunctionX implementation that knows how to serialize it's
members. We could restrict the types that as LiftSerializable on top
of primitives, Calenars, SessionVar/RequestVar etc. If users need
their own classes to be LiftSerilizable they would have to implement
LiftSerializable trait.

   I think we can do it without explicit traits.  I think we just need to
  walk
   the graph for everything that's added to the LiftSession and see where it
   leads.  Any graph we can walk is something that we can serialize... even
   without Java serialization.  Any graph that ends in globals or some class
   that refers to native stuff (e.g., IO), then we're toast.

  Totally agree. The rationale for explicit LiftSerializable would be
  just for user defined types. Otherwise user's won't have to use it.
  Graphs may also have be cyclic paths ... it shouldn't be too big of a
  pain though. Furthermore if a dependency graph path leads say to an IO
  reference maybe that's unintentional user code doesn't really use that
  but compiler put it for whatever reason. If such cases are possible
  and could be determined maybe we could exclude that silently from the
  serialization operation and add a compile time warning.

  I guess we need to dig more into scala compiler plugin system.

 1. Isn't there a problem with references _inside_ methods that are
 impure/sideeffecting?

 s = { Db.myCachedInfoNotInSession foo s  }

 Regarding member references, a simple check for transient
 (sca...@transient == java *transient*) to forcve people to use transient
 members for non-serializable state.

 But IMHO the serialization problem is a (negative?) sideeffect of Lifts rich
 model GUID=Func approach.
 Perhpas there is a middle way, a way where we can replicate just enough to
 survive a node crash?

That's exactly it. We probably don't need everything that Java
Serialization does. Just enough to make it consistent ... the
dependency graphs that is actually used by the user's function.






Thoughts?

Marius

 At a first glace Java serialization is needed because of its

 of the reference graph. But in the same time it does not perform
  well.
 One way might be the byte level instrumentation that would induce
  code
 to figure out the reference graph and know how to stream-ify it using
 a given efficient protocol. But that induces risks and it involves
 tons of work. I think would be doable though.

 The problem is not really the technology of propagating session
 information to other nodes. That's the easiest part, but tough one is
 figuring out the low level reference graph and serialization
 semantics. This is why JINI, JavaSpaces, JGroups, CORBA, JXTA, you
 name it, are unlikely to help solving the fundamental problem.

[Lift] Re: JPA blank archetype

2009-08-24 Thread Charles F. Munat

Hi, Marius...

I don't know what you mean by Are you using master? What I did was use 
the Maven archetype to create a basic JPA lift app. Then I changed 
directory to the top directory and ran mvn compile. That's it. I got 
the errors you see. I didn't do anything else.

I've tried blowing away .m2 and I've tried changing the scala version to 
2.7.5 (from 2.7.4). No difference.

Does the basic JPA lift app not compile until you do something else to 
it? The blank one worked fine. Can you create and compile the Basic JPA 
app on your machine without error? Maybe it's something on my machine, 
but everything else is working fine.

The Maven command I used is reproduced below.

Charles,

Sorry for the false noise, setting lift-core dependency to
version1.1-M4/version instead of  version1.1-SNAPSHOT/version
in web/pom.xml quite likely would help better.

/Indrajit

NB: I have had created a lift jpa project internally and played with
it for sometime. It took a while to filter out the exact delta wrt the
barebone archetype. Hope this helps.

Quite likely he is effectively on *latest* 1.1-SNAPSHOT as he used -

[Lift] How to create (meta) mapper mixin?

2009-08-24 Thread Jeppe Nejsum Madsen

Hi,

I'm trying to create some mixins to be applied to mapper/metamapper
objects to be used when objects are always owned by an account
(ie. a multi tenant db)

The mapper parts works fine:

trait OwnedEntity {
  self: BaseMapper =

  object account extends MappedLongForeignKey(this.asInstanceOf[MapperType], 
Account) {
override def dbColumnName = account_id
override def dbDisplay_? = false
override def defaultValue = Account.currentAccount
  }
}

but I can't seem to figure out the correct type bounds to create a
MetaMapper mixin that uses the above. Simple example with just a findMap
that finds all the entities owned by the current account:

trait MetaOwnedEntity[A : OwnedEntity] {
self: A with MetaMapper[A] =
  
// Find and map all entities owner by current account
def findMap[T](f: MapperType = Box[T]) : List[T] = findMap(By(account, 
Account.currentAccount))(f)
}

this fails compilation (1.1-SNAPSHOT), any clues?

EntityUtils.scala:23: error: overloaded method value apply with alternatives [O 
: net.liftweb.mapper.Mapper[O],T,Q : 
net.liftweb.mapper.KeyedMapper[T,Q]](net.liftweb.mapper.MappedForeignKey[T,O,Q],net.liftweb.util.Box[Q])net.liftweb.mapper.Cmp[O,T]
 and [O : net.liftweb.mapper.Mapper[O],T,Q : 
net.liftweb.mapper.KeyedMapper[T,Q]](net.liftweb.mapper.MappedForeignKey[T,O,Q],Q)net.liftweb.mapper.Cmp[O,T]
 and [O : 
net.liftweb.mapper.Mapper[O],T,U](net.liftweb.mapper.MappedField[T,O],U)(implicit
 (U) = T)net.liftweb.mapper.Cmp[O,T] cannot be applied to 
(MetaOwnedEntity.this.account.type,Long)
def findMap[T](f: MapperType = Box[T]) : List[T] = findMap(By(account, 
Account.currentAccount))(f)

     def findMap[T](f: MapperType = Box[T]) : List[T] = findMap(By(account,

 }

 this fails compilation (1.1-SNAPSHOT), any clues?

Folks,

Im sure others have noticed, but there are a serious amount of n00b
questions in and around mapper recently - this indicates to me that
people are not finding the information elsewhere (i.e. on our wiki).
Whilst I can document stuff I know about, there are a lot of stuff
people are asking about Mapper in particular that is outside of my

Can we just club together and all take a slice of the documenting pie?
It strikes me this would slash the volume of repetitive questions on

[Lift] Re: How to create (meta) mapper mixin?

2009-08-24 Thread Jeppe Nejsum Madsen

jon jonhoff...@gmail.com writes:

 Hi Jeppe,

 I did something similar with the following code:

 trait HasUser [T : HasUser[T]] extends KeyedMapper[Long, T]{
   self: T=
 object user extends MappedLongForeignKey(this, User) {
 override def dbColumnName = user_id
 }
 }

 trait HasUserMetaMapper[T : HasUser[T]] {
 self: T with LongKeyedMetaMapper[T] =

 def findAllByUserId(uid:Long) = findAll(By(user,uid))
 }

Thanks for this example. One difference is that you extend
KeyedMapper. I think it could be nice to avoid this (like what I have
below) to make the user/account mixin independent of the actual mapper
(and to enable several such traits to be mixed in. Not sure what happens
if several traits, each extending KeyedMapper, get mixed in??)

But now my head hurts from trying to figure out the correct type
declaration in MetaMapper to make this happen :-)

Looking at the latest sources jar for the JPA basic archetype, it has the

 Quite likely he is effectively on *latest* 1.1-SNAPSHOT as he used -
 DarchetypeVersion=1.1-SNAPSHOT during archetype:create.

 Would look forward to the archetype refactoring.

[Lift] Comet Chat

2009-08-24 Thread Bjarte Stien Karlsen

Hello lifted,

I am playing around with the 50ish line based comet example that dpp
has talked about in several talks and that is written more about here:
http://m.3wa.com/?p=304

Today I showed this to a friend and it looks like the focus of the
input box is lost when an update is received. Does anybody have a clue
on how this can be fixed? Is it not possible to just update part of
the DOM without having to steal the focus from the input field?

Actually, the input field is being removed from the DOM by the rendering of
the chat text.

You can see a more complete Comet chat example at
http://demo.liftweb.net/chat

The code separates the input box from the chats so that the input box is not
destroyed each time the comet update happens.

[Lift] Re: JPA blank archetype

2009-08-24 Thread Charles F. Munat

Yes, it compiles successfully when the lift-core dependency in the web 
pom.xml file is set to version 1.1-M4.

 Charles,
 
 Sorry for the false noise, setting lift-core dependency to
 version1.1-M4/version instead of  version1.1-SNAPSHOT/version
 in web/pom.xml quite likely would help better.
 
 /Indrajit
 
 NB: I have had created a lift jpa project internally and played with
 it for sometime. It took a while to filter out the exact delta wrt the
 barebone archetype. Hope this helps.

 Hi, Marius...

 I don't know what you mean by Are you using master? What I did was use
 the Maven archetype to create a basic JPA lift app. Then I changed
 directory to the top directory and ran mvn compile. That's it. I got
 the errors you see. I didn't do anything else.

 I've tried blowing away .m2 and I've tried changing the scala version to
 2.7.5 (from 2.7.4). No difference.

 Does the basic JPA lift app not compile until you do something else to
 it? The blank one worked fine. Can you create and compile the Basic JPA
 app on your machine without error? Maybe it's something on my machine,
 but everything else is working fine.

 The Maven command I used is reproduced below.

I'd get the latest snapshot. Wouldn't I?

[Lift] Re: JPA blank archetype

2009-08-24 Thread Charles F. Munat

I'm on a new laptop. I didn't do any git pulls of Lift stuff. I just 
installed Scala with the IZ installer and then Maven, then I ran the 
archetype command to create a basic JPA app and let it build the m2 
repository on my machine. When that didn't work, I blew away m2 and 
tried it again.

Changing the lift-core dependency worked. So the problem is definitely 
with 1.1-SNAPSHOT -- at least the one I ended up with.

Does this make sense? Do you see why I was confused by your reference to 
master?

Chas,

The problem is quite likely with the archetype jar in the scala-tools
repo. Derek is probably looking into it.
Yes, your being confused about the master reference is
understandable :)

Good that it compiles through. For now, you can set the dependencies
to lift-core and lift-jpa to 1.1-M4 and proceed merrily.

Hi Bjarte,

I am the one who wrote that post. It came out of a 1 hour presentation
that I did for my local java user group to show what lift can do. So it
was very minimal. Since most people attending are new to both
Scala and Lift.

I second David's suggestion. For a more full featured version
check out

http://demo.liftweb.net/chat

In fact http://demo.liftweb.net/ has quite a bit of example.
And I believe all the code are also available from David Pollak's

 of primitives, Calenars, SessionVar/RequestVar etc. If users need
 their own classes to be LiftSerilizable they would have to implement
 LiftSerializable trait.

I think we can do it without explicit traits.  I think we just need to
   walk
the graph for everything that's added to the LiftSession and see where

leads.  Any graph we can walk is something that we can serialize... even
without Java serialization.  Any graph that ends in globals or some

that refers to native stuff (e.g., IO), then we're toast.

   Totally agree. The rationale for explicit LiftSerializable would be
   just for user defined types. Otherwise user's won't have to use it.
   Graphs may also have be cyclic paths ... it shouldn't be too big of a
   pain though. Furthermore if a dependency graph path leads say to an IO
   reference maybe that's unintentional user code doesn't really use that
   but compiler put it for whatever reason. If such cases are possible
   and could be determined maybe we could exclude that silently from the
   serialization operation and add a compile time warning.

   I guess we need to dig more intoscalacompilerpluginsystem.

  1. Isn't there a problem with references _inside_ methods that are
  impure/sideeffecting?

  s = { Db.myCachedInfoNotInSession foo s  }

  Regarding member references, a simple check for transient

FYI, I did a local build and it's correct here, so something is going on in

 Yes, your being confused about the master reference is

 Good that it compiles through. For now, you can set the dependencies
 to lift-core and lift-jpa to 1.1-M4 and proceed merrily.

  Use traits to describe the pieces of your business logic rather than

  Don't use new, but use object's as factories that make run-time decisions

 My background is Java and a little bit of Spring. I read three Scala

 I need a little bit more input on structuring a web app and I hope to

 With Spring you let the container manage the classes. ok.
 I think my problem is, I dont know how you structured a web app in
 days
 without Spring.

 I would like to have Lift access my domain logic over an application
 layer (Domain

 In Wicket I would have my SpringBean annotation.

 So I hope to understand, how
 - can I access my app layer?
 - how could I organize my domain logic. I want to use DDD. I know I
 have to use
 object and class in a bigger sense...?

 I hope you guys can give me some hints.

 Thanks a lot

Totally agree. The rationale for explicit LiftSerializable would be

Graphs may also have be cyclic paths ... it shouldn't be too big of a
pain though. Furthermore if a dependency graph path leads say to an

 Hi
 i have form with text box and Submit button(with ajax Submit button)

 But when i submit the button form is not submitting so i am not able

 onclick function get called...


SHtml.ajaxButton is just that... a button that, when clicked by the user,
performs an ajax call to the server.




 Just i want to show text value in response with ajax ...
 how can i do this


Use SHtml.ajaxForm:


class Form2 {
  def render(xhtml: NodeSeq): NodeSeq = {
var user = 
def doAjaxThing(): JsCmd = {
  SetHtml(updated,
  spanHey Dude... I'm Form2 and the user is {user}/span)
}

SHtml.ajaxForm(
  bind(form, xhtml,
   user - SHtml.text(user, user = _),
   submit - (SHtml.hidden(doAjaxThing _) ++
input type=submit value=Click Me/)
 ))
  }
}


Or, if you use the lift:form tag in your view:

  div
Ajax Form v1: br/
lift:form
  lift:Form1
User: form:user/ br/
Okay? form:submit/
  /lift:Form1
/lift:form
  /div

You can do:

class Form1 {
  def render(xhtml: NodeSeq): NodeSeq = {
var user = 
def doAjaxThing(): JsCmd = {
  SetHtml(updated,
  spanHey Dude... I'm Form1 and the user is {user}/span)
}

bind(form, xhtml,
 user - SHtml.text(user, user = _),
 submit - (SHtml.hidden(doAjaxThing _) ++
 input type=submit value=Click Me/)
 )
  }
}

In enclosing running code that demonstrates both.

Thanks,

David

  members. We could restrict the types that as LiftSerializable on
 top
  of primitives, Calenars, SessionVar/RequestVar etc. If users
 need
  their own classes to be LiftSerilizable they would have to
 implement
  LiftSerializable trait.
 
 I think we can do it without explicit traits.  I think we just
 need to
walk
 the graph for everything that's added to the LiftSession and see
 where it
 leads.  Any graph we can walk is something that we can
 serialize... even
 without Java serialization.  Any graph that ends in globals or
 some class
 that refers to native stuff (e.g., IO), then we're toast.
 
Totally agree. The rationale for explicit LiftSerializable would be
just for user defined types. Otherwise user's won't have to use it.
Graphs may also have be cyclic paths ... it shouldn't be too big of
 a
pain though. Furthermore if a dependency graph path leads say to an
 IO
reference maybe that's unintentional user code doesn't really use
 that
but compiler put it for whatever reason. If such cases are possible
and could be determined maybe we could exclude that silently from
 the
serialization operation and add a compile time warning.
 
I guess we need to dig more intoscalacompilerpluginsystem.
 
   1. Isn't there a problem with references _inside_ methods that are
   impure/sideeffecting?
 
   s = { Db.myCachedInfoNotInSession foo s  }
 
   Regarding member references, a simple check for transient
   (sca...@transient == java *transient*) to forcve people to use
 transient
   members for non-serializable state.
 
   But IMHO the serialization problem is a (negative?) sideeffect of
 Lifts rich
   model GUID=Func approach.
   Perhpas there is a middle way, a way where we can replicate just
 enough to
   survive a node crash?
 
  That's exactly it. We probably don't need everything that Java
  Serialization does. Just enough to make it consistent ... the
  dependency graphs that is actually used by the user's function.
 
 
 
  Thoughts?

Thanks for all your help, Indrajit. I'm using the blank JPA app anyway,

Especially since I was using the Maven command from his book...

 Yes, your being confused about the master reference is

 Good that it compiles through. For now, you can set the dependencies
 to lift-core and lift-jpa to 1.1-M4 and proceed merrily.

  Does the user do anything to get the faster table updated or do you want
 the

 server?
 
  If it's the former (the user does something to get the faster table
  updated), you want to use ajaxButton... the user clicks on the button and
  the server-responds with JavaScript that updates the browser.
 
  If it's the latter (the user does nothing, but the server pushes changes

ajaxInvoke is a very low level call.  If you want to have an Ajax

use SHtml.ajaxButton.  If you want to have an Ajax form, use

OK, I think I've found an issue here. The sha1 checksum file for the
archetype was last updated on August 1st, and haven't been updated since
then. That's what your original error was, and it's why it's grabbing an
older version of the jar :(. Let me see if I can figure out why hudson won't

 I think we can do it at runtime in development mode.  This is just for

 on top
  of primitives, Calenars, SessionVar/RequestVar etc. If users
 need
  their own classes to be LiftSerilizable they would have to
 implement
  LiftSerializable trait.
 
 I think we can do it without explicit traits.  I think we just
 need to
walk
 the graph for everything that's added to the LiftSession and see
 where it
 leads.  Any graph we can walk is something that we can
 serialize... even
 without Java serialization.  Any graph that ends in globals or
 some class
 that refers to native stuff (e.g., IO), then we're toast.
 
Totally agree. The rationale for explicit LiftSerializable would be
just for user defined types. Otherwise user's won't have to use it.
Graphs may also have be cyclic paths ... it shouldn't be too big of
 a
pain though. Furthermore if a dependency graph path leads say to an
 IO
reference maybe that's unintentional user code doesn't really use
 that
but compiler put it for whatever reason. If such cases are possible
and could be determined maybe we could exclude that silently from
 the
serialization operation and add a compile time warning.
 
I guess we need to dig more intoscalacompilerpluginsystem.
 
   1. Isn't there a problem with references _inside_ methods that are
   impure/sideeffecting?
 
   s = { Db.myCachedInfoNotInSession foo s  }
 
   Regarding member references, a simple check for transient
   (sca...@transient == java *transient*) to forcve people to use
 transient
   members for non-serializable state.
 
   But IMHO the serialization problem is a (negative?) sideeffect of
 Lifts rich
   model GUID=Func approach.
   Perhpas there is a middle way, a way where we can replicate just
 enough to
   survive a node crash?
 
  That's exactly it. We probably don't need everything that Java
  Serialization does. Just enough to make it consistent ... the
  dependency graphs that is actually used by the user's function.

   The problem is not really the technology of propagating

 tough one is
   figuring out the low level reference graph and serialization

[Lift] Multiple sites, same login

2009-08-24 Thread Charles F. Munat

I'm building two Lift applications that access the same back end 
database -- one is for the public site, and the other, which will use a 
subdomain, is for administration of the public site.

A third application will access a separate database, but will be related 
to the previous two sites.

Any suggestions as to how I might have one login that keeps the user 
logged in across all these sites? Obviously, OpenID would work, and 
there's complex stuff involving LDAP servers, etc., but I'd like to keep 
it fairly simple.

Ideas?

Thanks!
Chas.

I'm going to merge in the fix for issue #36 (

[Lift] id selectors discouraged?

2009-08-24 Thread Meredith Gregory
Lifted,

At the pixillion master
http://github.com/leithaus/pixillion/tree/masteri've an example
where it appears that id selectors are not working
correctly... Or, maybe i just don't know how to use CSS. The site map (after
login) will show three pages of interest: paint, chat, combo. Paint is raw
js without lift intervention and works as intended (for now). Chat is
cribbed from the lift chat example. Combo attempts to put the two on the
same page with lift tags in the drivers seat. As you can see the style is
not being governed in the same way on the combo page, causing erroneous
behavior in the paint rendering. Any help would be greatly appreciated.

Best wishes,

[Lift] multiselect example in Liftbook problem

2009-08-24 Thread glenn

There seems to be a problem with  SHtml.multiSelect following the
example in the Lift book (Listing 4.10: Using multiselect). The
example shows the last parameter to be a List, while the source for
multiSelect shows it to be
(String) = Any.

When I tried to implement in my own code, I get the compiler error:
type mismatch found; List[String], required: String.

The book example even states that the function takes a String
representing a
Category’s primary key and returns the category.

The example goes further to explain:

We then use this helper method to update the
Set that we created earlier. Note that the callback function will be
executed for each selected item
in the multiselect, which is why the callback takes a String argument
instead of a Set[String].

But where is this callback function? Is it the same helper mentioned
earlier. There's no other callback function parameter on the
multiSelect constructor.

This is all very confusing.

[Lift] Re-factored Archetypes

2009-08-24 Thread Timothy Perrett

Guys,

As promised, i've re-factored the archetypes (now in their own
submodule and building as part of master) however their maven group
and artifactId's are the same, so all commands etc will continue to
work (its purely a code base organization change)

Moreover, i've fixed the various issues with velocity in the jpa-basic
archetype (its late here, i'll fix the others 2mro) and i've also
fixed the Jetty version in all the pom.xml to a sensible range.

Enjoy...

I found that the example is out-of-sync with the latest code in 1.1-

I was able to get the example (in my application, at least) to compile
and run, by
defining the function as loadCategory(List[String]) = ...,
and creating a separate submit function to handle the actual save
chores.

 Lifted,

 At the pixillion master 
 http://github.com/leithaus/pixillion/tree/masteri've an example where it 
 appears that id selectors are not working
 correctly... Or, maybe i just don't know how to use CSS. The site map (after
 login) will show three pages of interest: paint, chat, combo. Paint is raw
 js without lift intervention and works as intended (for now). Chat is
 cribbed from the lift chat example. Combo attempts to put the two on the
 same page with lift tags in the drivers seat. As you can see the style is
 not being governed in the same way on the combo page, causing erroneous
 behavior in the paint rendering. Any help would be greatly appreciated.


If you remove the:

   lift:CSS.blueprint /
lift:CSS.fancyType /

lines from /templates-hidden/default.html, you'll get a much better result.
The CSS in Blueprint CSS is munging the CSS used by the paint program.

Please take a look at Firebug... it's a debugger for browsers... you can see
exactly how the browser applies style to each element.  It's mighty helpful.

On other notes, any JavaScript on the page *must* be escaped in ![CDATA[
blocks:

script type=text/javascript
$(document).ready(function() {

   /script

becomes:

  script type=text/javascript
// ![CDATA[
$(document).ready(function() {
...
   // ]]
   /script

The change set I sent out the last time you used the pixillion stuff as an
example should be applied to your project.  It fixes the Scala version issue
as well as the script escaping issue.

 jonasboner.com/2008/10/06/real-world-scala-dependency-injectio...
  ?
  I understand the example.
 
  What do you mean by objects? The object Scala keyword?
 
  It would be great if you can give me a little example. How to glue it
  with a Lift Snippet.
 
  Thanks
  kind regards

Hello Timothy,
 
thank you.
I know that I do not need Spring for Scala.
I dont expressed it well. How do I glue my app parts
together. And how do I glue the lift part with a facade or
application service of my domain layer.
 
   Use traits to describe the pieces of your business logic rather than
   classes.  Traits can be composed very easily.
 
   Don't use new, but use object's as factories that make run-time
 decisions
   about how to compose traits and vend them.
 
Thanks for your help

  Hello Lift Community,
 
  I want to implement a new Project in Scala with Lift. I am new to
  Scala/Lift.
  Scala looks great and it expanded my horizon. FP is a new concept
 to
  me.
 
  My background is Java and a little bit of Spring. I read three
 Scala
  books
  and a lot on blogs. But there is a missing part for me on how to
  combine
  my classes. I read the Scalable Components Paper and I dont get
 it
  100%.
  I need a little bit more input on structuring a web app and I
 hope to
  get the 100%
  with you guys.
  With Spring you let the container manage the classes. ok.
  I think my problem is, I dont know how you structured a web app
 in
  days
  without Spring.
 
  I would like to have Lift access my domain logic over an
 application
  layer (Domain
  Driven Design).
  In Wicket I would have my SpringBean annotation.
 
  So I hope to understand, how
  - can I access my app layer?
  - how could I organize my domain logic. I want to use DDD. I know
 I
  have to use
  object and class in a bigger sense...?
 
  I hope you guys can give me some hints.
 
  Thanks a lot

[Lift] Mapper with custom id

2009-08-24 Thread Naftoli Gugenheim

I'm trying to import data from a non-mapper-based database to one that is. I'm 
reading data with DB.exec and trying to save it using Mapper, but it's not 
getting saved. I'm guessing that since I'm setting the id (in runSafe) it 
thinks it needs to do an update, not an insert.  Is there a workaround? Also, 
doesn't this scenario break the logic of MetaMapper.saved_?() ? Wouldn't it 
make more sense to have a saved flag that is cleared by default and set when 
it's created as a result of a find, and after it's saved?

 I am trying to make a simple ajax form. The code is below. The

 uncaught exception ReferenceError: F777221462447MPT is not defined

 Am I missing something?

 lift:surround with=default at=content
h1Hello FormAjax/h1
lift:HelloFormAjax.show
Hello hello:who/br/
label for=whoFieldWho :/labelhello:whoField/
hello:submit/
/lift:HelloFormAjax.show
 /lift:surround

 create src/main/scala/sandbox/lift/hellodarwin/snippet/HelloFormAjax
 package sandbox.lift.hellodarwin.snippet

 import scala.xml.NodeSeq
 import net.liftweb.http.S._
 import net.liftweb.http.SHtml._
 import net.liftweb.util.Helpers._
 import net.liftweb.http.js.{JsCmd, JsCmds}

 class HelloFormAjax {
  def whoNode(str: String) = span id=who{str}/span

  def updateWho(str: String): JsCmd = {
println(updateWho on  + str)
JsCmds.Run($('#who').text('+str+'))


 This will fail if str contains any non-printables or '.  Please use:

 str.encJs

 To encode a Scala String into a JavaScript friendly String.

 But better, you could use:

 SetHtml(who, scala.xml.Text(str))



  }






  def show(xhtml: NodeSeq): NodeSeq = {
bind(hello, xhtml,
whoField - text(world, null) % (size - 10) % (id -
  whoField),
submit - button type=button{?(Send)}/button %
 (onclick - ajaxCall(JsRaw($('#whoField').attr('value')), s =
 updateWho(s))),



 ajaxCall returns a tuple of (String, JsExp).  I'm not sure why the compiler
 is letting that get converted into the second half of a pair for
 UnparsedAttribute purposes... but... in order to use it, you must do:
 ajaxCall(JsRaw($('#whoField').attr('value')), s =updateWho(s))._2

 But... it'd be better to ValById:

 ajaxCall(ValById(whoField), , s =updateWho(s))._2

 I've added a few helpers to ajaxButton, so you can do:

 submit - ajaxButton(Text(?(Send)), ValById(whoField), s =
 updateWho(s))



who - whoNode(world)
)
  }
 }

 Lifted,

 At the pixillion 
 masterhttp://github.com/leithaus/pixillion/tree/masteri've an example 
 where it appears that id selectors are not working
 correctly... Or, maybe i just don't know how to use CSS. The site map (after
 login) will show three pages of interest: paint, chat, combo. Paint is raw
 js without lift intervention and works as intended (for now). Chat is
 cribbed from the lift chat example. Combo attempts to put the two on the
 same page with lift tags in the drivers seat. As you can see the style is
 not being governed in the same way on the combo page, causing erroneous
 behavior in the paint rendering. Any help would be greatly appreciated.


 If you remove the:

lift:CSS.blueprint /
 lift:CSS.fancyType /

 lines from /templates-hidden/default.html, you'll get a much better
 result.  The CSS in Blueprint CSS is munging the CSS used by the paint
 program.

 Please take a look at Firebug... it's a debugger for browsers... you can
 see exactly how the browser applies style to each element.  It's mighty
 helpful.

 On other notes, any JavaScript on the page *must* be escaped in ![CDATA[
 blocks:

 script type=text/javascript
 $(document).ready(function() {
 
/script

 becomes:

   script type=text/javascript
 // ![CDATA[
 $(document).ready(function() {
 ...
// ]]
/script

 The change set I sent out the last time you used the pixillion stuff as an
 example should be applied to your project.  It fixes the Scala version issue
 as well as the script escaping issue.
