[Lift] Issue, The URL params can't contains ? ****

2010-03-09 Thread Neil.Lv
Hi all,

  I have a silly question about the URL rewrite .

  How to let the URL params can contains the  character.

  Here is the code:

###  The url rewrite.
case RewriteRequest(
   ParsePath(List(download,  link), html, _, _),
 GetRequest, _) =
   RewriteResponse(List(download),
 Map(link - link))
###

  When i input this link and get these value that the link param can't
contains the  char.
http://localhost:8080/download.html?link=http://test.com/file.zip12345678

  The link param is:  (that doesn't contains the  char  in the param)
  S.param(link)
  = http://test.com/file.zip

  So how can i get the 12345678 value from the link param ?

  Maybe the URL rewrite is not correctly ?

  Thanks for any help!

Cheers,
  Neil

 I'm not sure if this can be handled with the standard ParsePath, but it
 is fairly easy to write your own extractor that can handle more complex
 scenarios. Here's an example:

 object ParamsExtractor {
   def unapply(pp:ParsePath): Option[(Account, OrgUnit)] = {
 val result:Box[(Account, OrgUnit)] = if 
 (pp.wholePath.startsWith(path)  pp.wholePath.length == (path.length + 2)) {
   val res = Full((XX,YY))
   debug(Decoded URL: %s=%s.format(pp,res))
   res
   }
 else
   None
 result
   }
 }
 used like this:

 case RewriteRequest(ParamsExtractor(account,orgUnit) , _, _) =
 (RewriteResponse(path), Full(account, orgUnit))

  I have some question about these code that i don't understand.

  The first one that contains the Map() in the RewriteResponse() .
   --
   case RewriteRequest() = RewriteResponse()

  but the second one that doesn't contain the Map in the
RewriteResponse(),
  what's the mean of the Full(account, orgUnit) in the
( RewriteResponse(path), Full(account, orgUnit) )
   --
   case RewriteRequest() = ( RewriteResponse(), Full() )

###

  case RewriteRequest(
  ParsePath(List(show, img, version, id), _, _,_), _, _) =
RewriteResponse(List(show, img),
  Map(version - version, id - id)
)


  case RewriteRequest(
  ParamsExtractor(account,orgUnit) , _, _) =
( RewriteResponse(path), Full(account, orgUnit) )

 Ahh yes, the example was from a Loc rewrite, The principle is the same I
 guess, you should be able to do something like this:

 The important part is the extractor which takes care of parsing the
 request into meaningful values...

 This is just basic pattern matching stuff.  So,

 RewriteResponse(List(show, img),
  Map(version - version, id - (rest.firstOption getOrElse N/A))

 Please pick up a copy of one of the Scala books and look at the pattern
 matching section related to Lists.  There's a lot of flexibility that's no
 Lift-specific, but that Lift leverages.

 val entries = Menu(Loc(Home, List(index), Home)) ::



  Menu(Loc(show, List(show), show, Hidden)) :: User.sitemap

  ###

   BTW, I use the LiftView to handle the request.

  ###
  class show extends LiftView {
   def dispatch = {
 case img = imgDispatch _
 case _ = allDispatch _
   }

   def imgDispatch(): Box[NodeSeq] = {
 ...

   def allDispatch(): Box[NodeSeq] = {

   Of course, please replace 2.7.7 in the dependency above with your

   1. What is the most straightforward way to POST to an external

   I'm going to be sending Solr server XML commands to index and

   data for search within my app, and I've seen people discuss
  Scala's

  or
   if I should use it over apache http library or curl.

   2. Would it be safe to say that this use case (sending POSTs to
  an
   external URL asynchronously) is a good thing for Lift's actors to
   handle? I'm very green to the concept of actors, so I'm trying to
  find
   when it's best to use them.

   3. I'm planning on doing a monthly rebuild of the index (or
  possibly
   some other timespan tbd), and I've read that Quartz is good for
   scheduling. Is there documentation I can read for information on
  how
   to integrate this Java library (or any java library for that
  matter)
   into my lift app and use it?

[Lift] Re: Solr (or external API), curl, scala dispatch library, Quartz scheduling questions

2010-01-26 Thread Neil.Lv

  Thanks, I have found it here, 
http://dispatch.databinder.net/Stdout_Walkthrough

  I have imported the Http package and it works now,
###
import Http._

   Thanks again, this article is very helpful.

Cheers,

  Hi,

I have a silly question about the http package.

   What's the package should be imported when using the dispatch?

   I try this code of the wiki, and get this error.

 ###  I have import the dispatch package, and where is the http ?
 import dispatch._

Ok thanks!

For those of you looking to do add Databinder's dispatch to your Lift
project, you should add these to your pom.xml:

within repositories...
repository
  idnet.databinder/id
  urlhttp://databinder.net/repo/url
  snapshots /
/repository

within dependencies...
dependency
  groupIdnet.databinder/groupId
  artifactIddispatch-http_2.7.7/artifactId
  version0.6.6/version
/dependency

Of course, please replace 2.7.7 in the dependency above with your
version of scala, and 0.6.6 with whatever version of Dispatch you
plan to use. You can browse their repository online (http://
databinder.net/repo/) and see what's most up to date if you're into
that.

Hey all,
I'm planning on using solr for a web project that I'm doing, and
   I was
wondering if anyone had experience with using Solr or
   communicating
with another external xml api? I've got a few questions.

1. What is the most straightforward way to POST to an external
   url?
I'm going to be sending Solr server XML commands to index and
   commit
data for search within my app, and I've seen people discuss
   Scala's
Dispatch library, but I'm not exactly sure what its strengths 
are
   or
if I should use it over apache http library or curl.

2. Would it be safe to say that this use case (sending POSTs to
   an
external URL asynchronously) is a good thing for Lift's actors 
to
handle? I'm very green to the concept of actors, so I'm trying 
to
   find
when it's best to use them.

3. I'm planning on doing a monthly rebuild of the index (or
   possibly
some other timespan tbd), and I've read that Quartz is good for
scheduling. Is there documentation I can read for information on
   how
to integrate this Java library (or any java library for that
   matter)
into my lift app and use it?

Thanks!

[Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?

2010-01-21 Thread Neil.Lv

  The users table in the OneDB, and the hots table in the TwoDB, they
are separated!

  I have changed the method that like this:
###
  # I specify the TwoDB for hots table.
  override def dbDefaultConnectionIdentifier = bootstrap.liftweb.TwoDB


  def getHots3(id : Long) = {
DB.use(bootstrap.liftweb.OneDB) {
  firstConn =
 DB.use(bootstrap.liftweb.TwoDB) {
conn =
 DB.prepareStatement(SELECT * FROM hots WHERE id?, conn) {
 stmt =
 stmt.setLong(1, id)
 stmt.executeUpdate()
}
}
}
  }

  But it doesn't work.

 Note that DB.use nests such that the transaction will only be committed when
 the last DB.use block for a given ConnectionIdentifier is exited.

[Lift] How to use prepareStatement to select *** from DB (two db vender)?

2010-01-20 Thread Neil.Lv
Hi all,

  I use two db connections in my app, and I want to use
DB.prepareStatement to select
the records from the second db.

  It failed, Here is the code:
###
  def getHotByTid(id : Long) =
DB.use(bootstrap.liftweb.TwoDB) {
  conn =
  DB.prepareStatement(SELECT * FROM hots WHERE id=? , conn) {
  stmt =
  stmt.setLong(1, id)
Log.info(stmt : + stmt)   // The information is correctly now, but
after call executeUpdate method
  stmt.executeUpdate()
   }
   }
###

  The update statement can works well:
###
  def updateCountsById(id : Long) =
DB.use(bootstrap.liftweb.TwoDB) {
  conn =
  DB.prepareStatement(UPDATE hots set count=count+1 WHERE id=?,
conn) {
stmt =
   stmt.setLong(1, id)
   stmt.executeUpdate()
  }
   }
###

   Thanks for any suggestion that will be appreciated.

Cheers,
  Neil

[Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?

2010-01-20 Thread Neil.Lv


Mabye it's a bug with DB.runQuery and DB.use in the two db vender 

Two question: (problem)

1: I don't know why the HelloWorld snippet code will be execute 2
times in this code. (See the HelloWorld.scala file.)
2: The dbDefaultConnectionIdentifier method in the Model that it works
fine when using Mapper's method such as ModelName.findAll(),
it doesn't work when using DB.runQuery and DB.use(...) --- (Maybe it
can't find the default db identifier)

The question 2 I test it many times that found this problem.

In the test app , the Hot.getHots2 and Hot.getHots3 method can't work.

I comment the code now in the HelloWorld.scala file, you can try it.



  I can push the code on the github, and get this errors fatal:
unable to fork

  So If anyone know what's wrong with it and I can send the demo.tar
file through the email.

  Thanks very much!

  Neil

   Ie

  I've put the image gallery code I've been working on up at:

  could do better with this.

  Oh, one caveat -- I've set Jetty to run on port 9080 within this code,
  so use accordingly when playing with this.

  This code, building on David Pollak's image upload example, provides an
  image gallery with support for uploading, renaming, categorizing and
  deleting images, as well as browsing uploaded images by category.

  This is still very much a work in progress -- next steps from where I'm
  sitting are:

   a.) some corner cases of form validation -- don't allow categories to
   be created with a '/' in their name, as this breaks the URL
   rewrites

   b.) Ajax, Ajax, Ajax

   c.) make it easier to use this within a larger project -- this is
   already split into a separate package hierarchy from the
   surrounding project, but I'd like to follow the ProtoUser stuff
   in, eg, providing a canned Sitemap fragment for a surrounding
   project to use.

   d.) require a logged in user to upload or edit, but anyone can view
   (easy enough to add -- I've done it in other code -- but I haven't
   done it here)

   e.) reduce the number of queries this makes -- it's not too heavy, but
   some convenience functions encapsulating joins could still save some.

  Anyway, I'd love any thoughts on what I could be doing differently here,
  and hope this helps anyone else who is, like me, just starting out with
  lift.

  user 2: message 2
  user 3: message 3
  user 4: message 4
  user 5: message 5

   Here are 5 messages, then i want to refresh the messages when the

  ###
  user 1: message 1
  user 2: message 2
  user 3: message 3
  user 4: message 4
  user 5: message 5
  refresh:  can't refresh, also show 6 messages, i want to show 5
  messages.
  ###

   Here is code in the Comet:
  ###
  lass Chat extends CometActor with CometListener {
  ...
   override def lowPriority = {
     case ChatServerUpdate(value) =
       val update = (value -- chats).reverse.map(b = AppendHtml
  (infoId, line(b)))
       partialUpdate(update)
       chats = value.take(5)
   }
  ...
  }
  ###

    In the example, when the message counts =5, i set the count to 5
  via
   ###
   chats = value.take(5)
  ###

    Is there a js function can do this, when the chats's size is bigger
  than 5, then refresh the messages.

   Thanks for any suggestion!

  Well from your Snippet method you can just use HttpURLConnection, or
  Apache Commons Client to make remote requests to other services. Of
  course typically you won't do this directly from the snippet method
  but from a Service layer of your application. One you get the response
  (say it's an XML) you parse it using Scala XML class and the extract
  relevant information using pattern matching or by some other means.
  From here you just construct the NodeSeq that the Snippet/View needs
  to return.

  As a side note ...
  If those requests are taking a long time, you can wrap your snippet in
  lift:lazy-load ... and it will be loaded asynchronously. There is
  another attribute (lift:parallel=true)that you could specify to a
  snippet that it will be run asynchronously allowing other snippets to
  process and the result will be merged into the HTTP response right
  before sending the response to the client. Note that you need to set
  LiftRules.allowParallelSnippets

Hi all

   I have a silly question about the Chat demo.

   How could i create a Chat room in this demo ?

   Maybe i can define a variable or some other method to achieve the
purpose !

   Now all the people are in the same Chat room ( global ) in the
example, so i want to create more than one
Chat rooms that every one can contain 100 people.

   Thanks for any suggestion!

[Lift] How to reRender the page via js in Chat demo of the lift ?

2009-12-19 Thread Neil.Lv
Hi all,

  How to reRender the page via js in Chat demo of the lift ?

  Here is an example:
###  In the index page, show all the message that the users sent
user 1: message 1
user 2: message 2
user 3: message 3
user 4: message 4
user 5: message 5
###

  Here are 5 messages, then i want to refresh the messages when the
message count 5,
###
user 1: message 1
user 2: message 2
user 3: message 3
user 4: message 4
user 5: message 5
refresh:  can't refresh, also show 6 messages, i want to show 5
messages.
###

  Here is code in the Comet:
###
lass Chat extends CometActor with CometListener {
...
  override def lowPriority = {
case ChatServerUpdate(value) =
  val update = (value -- chats).reverse.map(b = AppendHtml
(infoId, line(b)))
  partialUpdate(update)
  chats = value.take(5)
  }
...
}
###

   In the example, when the message counts =5, i set the count to 5
via
 ###
 chats = value.take(5)
###

   Is there a js function can do this, when the chats's size is bigger
than 5, then refresh the messages.

  Thanks for any suggestion!

Cheers,
  Neil

Hi all,

  How can i specify the Interval time for the Comet ?

  Just like the chat demo in the lift examples, i have a problem that
how to set
the interval time for the every http request ?

  That means the user only post the message to the comet every 3
seconds, and doesn't post
the message all the time.

 Thanks for any suggestion!

   If there are many people in the Chat room, and there is a person

 The polling is not periodic, it's constant and the polling for Comet takes

 What is the advantage that you see to a periodic poll rather than the

[Lift] How can bind more than one element in the render method in CometActor ?

2009-12-08 Thread Neil.Lv
Hi all,

   How can bind more than one element in the render method in
CometActor ?

   The msg1 is an
###
class TestComet extends CometActor {
  override def defaultPrefix = Full(info)
  ...
  def render = { bind(One   - span1/span,
 Two   - span2/span,
 Three - span3/span,
 Four  - span4/span,
 Five  - span5/span,
 Six   - span6/span ) }
  ...
}
###

  And in the index.html page
###
...
lift:comet type=TestComet
  info:One/
/lift:comet
span/span
lift:comet type=TestComet
  info:Two/
/lift:comet
span/span
lift:comet type=TestComet
  info:Three
/lift:comet
span/span
lift:comet type=TestComet
  info:Four
/lift:comet
...
###

  And these four comet all show the same result  span3/span,
not 1, 2, 3, 4, 5, 6 

  I don't know what's wrong with it ?

  Dose anybody know what's the problem with this render metho?

  Thanks for any help.

Cheers,
  Neil

  BTW, when the partialUpdate method is called , the result is
correct.

  But when refreshing the browser or open a new browser, the result
also is 3,

[Lift] Re: How can bind more than one element in the render method in CometActor ?

2009-12-08 Thread Neil.Lv

   Here is the code:
###
override def defaultPrefix = Full(info)

def show(in: NodeSeq): NodeSeq = {
  bind(show, in,
   list1 - Text(1),
   list2 - Text(2)
   )
}

def render = {
  bind(
   list1 - Text(1),
   list2 - Text(2)
   )
}
###

   In the index.html page:

###
lift:comet type=ForumComet
  info.show:list1/
  info.show:list2/
/lift:comet

lift:comet type=ForumComet
  info.list1/
  info.list2/
/lift:comet
###

  Both of them don't work, In the Snippet, the render method could be
write like this:
###
def render(in : NodeSeq) : NodeSeq = {
   bind( info, in,
   list1 - Text(1),
list2 - Text(2)
  )
}
###

  It's different with Comet's render method .

  Thanks!

  Neil

 Neil,

 bind() works the same everywhere... CometActors, Helpers.bind, etc.

 If you are having a problem with bind, I would strongly recommend writing a
 test with a template that allows your to figure out how bind works and then
 take the template and binding and put it in your CometActor.

 Thanks,

 David

 A CometActor is a subclass of LiftActor

 If you can package up a complete simple implementation of the problem (an

 I think there might be a problem with the way you are specifying which
 db to use in your mapper classes. Here's the relevant text from the
 The Lift Book:

 dbSelect... is used to find an instance by primary key, and takes a
 partial function (typically a match clause) to determine which
 connection to use.

 dbCalculate... is used when a new instance is created to decide where
 to store the new instance.

 Those 2 methods are used for sharding. Are you sharding? If not I
 think you just want to override dbDefaultConnectionIdentifier

  I added this code in the User model, but it doesn't work yet.

  This println method is never executed.

  Maybe some configuration need to be set ?

[Lift] (Maybe it's a bug ?) About the Schedule's execute counts in the ActorComet

2009-12-03 Thread Neil.Lv
Hi all,

   Here is an example code that about the ActorComet.

###
package com.liftcode.comet

import net.liftweb._
import http._
import js._
import JsCmds._
import net.liftweb.common._
import net.liftweb.util._
import Helpers._
import net.liftweb.http._
import _root_.scala.xml._
import scala.actors._
import scala.collection.mutable.Queue
import net.liftweb.http.SessionVar

case class Foo(getValue: String)

object FooManager {
  private var foos: List[Foo] = Nil
  def getFoos: List[Foo] = synchronized {
println(  foos size:  + foos.size)
foos ::= Foo(System.currentTimeMillis.toString)
foos
  }
}

class MyComet extends CometActor {

  override def defaultPrefix = Full(auth)

  private var foos = FooManager.getFoos

  def createDisplay(foos:List[Foo]):NodeSeq = {
span id=gotable
{
  for {foo - foos} yield trtd{foo.getValue}/td/tr
}

/table/span
  }

  def render = { bind(foo - createDisplay(foos)) }

  override def localSetup = {
println(  localSetup:  )
super.localSetup
this ! Tick
  }

  override def lowPriority = {
case Tick = {
println(   Tick )
  foos = FooManager.getFoos
  reRender(false)
  ActorPing.schedule(this, Tick, 10 seconds)
}
  }
}

case object Tick
###

   When i run  mvn jetty:run  to start the server, and type the
http://localhost:8080 in the browser.
The result will be like this, the println(   Tick ) method
only execute 1 time every 10 seconds.

###
INFO - Service request (GET) /comet_request/50054201120/farmqqw03xkm

liseconds
   Tick 
  foos size: 2
INFO - Service request (GET) /comet_request/87077494133/farmqqw03xkm
took 8625 M
###

   Then i don't close the browser, and Ctrl+C stop the jetty server,
and  mvn jetty:run  restart the server, the result will be like this:
The  println(   Tick ) method will be execute 3 times every
10 seconds.

###
INFO - Service request (GET) /comet_request/74875169086/farmqqw03xkm

iseconds
  foos size: 8
  localSetup:

  foos size: 10
  localSetup:
   Tick 
  foos size: 11
INFO - Service request (GET) / took 31 Milliseconds
###

   I don't know what's wrong with it .
   If when you stop the server, and close the browser immediately,
then use mvn jetty:run to start the server, and open a new browser to
visit http://localhost:8080,  the result is correctly.

   Thanks for any suggestion!

Cheers,
  Neil

use the iframe to embed the test.html.

###
iframe frameborder=1 scrolling=yes style=height: 5px; width:
5px; src=test.html name=lift/iframe

 ActorPing is what you want, yes. Essentially, calling it says in X time span

 ping at the end of the Z method to reschedule it.

 That should be all you need.

 Hi,

 I'm a Lift newbie so I don't know if my way is the right way but
 here goes:

 I generated my app using the archetype lift-archetype-basic in order
 to get the database configuration stuff to Boot.scala. Then i created
 two files src/main/webapp/WEB-INF/classes/props/default.props and
 production.default.props. When developing I want to use an in memory
 database so I added:

 db.driver = org.apache.derby.jdbc.EmbeddedDriver
 db.url = jdbc:derby:my_database_name;create=true

 to default.props. I want to use MySQL on the production server so I
 added:

 db.driver = com.mysql.jdbc.Driver
 db.url = jdbc:mysql://localhost:3306/my_database_name
 db.user = my_user
 db.password = my_pass

 to production.default.props. On the production server I user Tomcat
 with -Drun.mode=production.

 I hope you get some ideas about my configuration.

You don't build for deployment, it is the same war (modulus any compiler
settings or other build steps you've specified)

The lift run mode is determined at runtime, so you need to specify the
run.mode=production as a system property when launching jetty

(This is what happens with the maven command above: It starts jetty with
this system property set)

If you happen to run jetty on a Debian based Linux you can accomplish
this by:

[Lift] Re: How to save the uploaded image into the folder via fileUpload in Lift?

2009-11-15 Thread Neil.Lv

Tim,

  I'm not clear that how to do use the caching proxy and maps a URL to
the dispatcher.

  I didn't find the archive about the SoftReferenceCache.

  Is there some exmaple that descript how to use is ~?

  :)

  Thanks very much!

Cheers,

 Neil,

 If you want to save the byte array, save it into the database, then just 
 write a caching proxy that maps a URL to the dispatcher. That is, use 
 SoftReferenceCache to cache the database read so that the next time the image 
 is requested there is no database hit.

 This has been discussed a fair few times on the list if i remember rightly, 
 so best off searching the archives if your not sure where to start.

  It try to deploy the war to the tomcat5.5.25, and the path is
different.

  Use LiftRules.getResource(/images/) to get this information:

   In the dev box:
   -- Path:Full(file:/G:/project/demo/src/main/webapp/images/

   In the tomcat:

2009-11-14 Thread Neil.Lv

Hi all,

  Thanks for your tips, and I have some silly question about this.

  1:)  a directory that's not part of the app's exploded WAR file

  The direcotry tree like this, and Where is i can create a well
defined directory
that's not part of the app's exploded WAR file ? I'm notfamiliar
with this.

###
demo
  --src
--main
  --resources
--i18n
--props
  --scala
  --webapp
--test
  --target
###

  2:) If I store images to the RDBMS, and how can it be shown in the
webpage ?
###
   FileParamHolder(_, mime, name, data)
   
   item.receipt(data).receiptMime(mime)   // ( Array[Byte] that saved
into database )

  :)

  Thanks very much !

 You cannot rely on being able to write to a directory in an application.
 This is dependent on how the specific web app container handles things, but
 I would strongly suggest you write images to a directory that's not part of
 the app's exploded WAR file.  And strongly is a very weak description of
 how forceful I'm being about this.  This kind of code may change behaviour
 between your dev box and production, between versions of your app container.

 If you want to store images to serve, either use a well defined directory
 outside your WAR file or put stuff in your RDBMS or put stuff up on Amazon
 (like Twitter does with images).  Amazon has much better infrastructure for
 dealing with serving static content than just about anyone else.

   Thank you very much !
