[Lift] Re: file upload
Hey Oliver, I was referring to large uploads - with the current scheme the entire file is read into memory, so if you upload, say, a 400 or 500mb file you'll find that your entire stack bloats in size.

[Lift] Re: file upload
I do similar things.
First there is a snippet using the bind functionality.
var image : FileParamHolder = _
bind("widget", xhtml,
"image" -> fileUpload(image = _)
}
Now write out:
val wbos : ByteArrayOutputStream = build(image)
val fout = new File(outputFilename)
if (fout.exists()) {
Log.error("Tried to overwrite existing file")
return "Error: Filename already exists"
}
val foStream = new FileOutputStream(fout)
foStream.write(wbos.toByteArray())
foStream.close()
def build(image : FileParamHolder) : ByteArrayOutputStream = {
val bout = new ByteArrayOutputStream()
val zipout : ZipOutputStream = new ZipOutputStream(bout)
zipout.setMethod(ZipOutputStream.DEFLATED);
zipout.setLevel(Deflater.DEFAULT_COMPRESSION);
writeImage(zos, image)
}
private def writeImage(zos: ZipOutputStream,
image:FileParamHolder):Unit = {
if (image.fileName == "") {
Log.info("Provided image file is null")
return
}
if (image.fileName.lastIndexOf("\\") != -1) //this is needed if
upload is from a windows system
zos.putNextEntry(new ZipEntry("res/" + image.fileName.substring
(image.fileName.lastIndexOf("\\")+1)))
else
zos.putNextEntry(new ZipEntry("res/" + image.fileName))
zos.write(image.file, 0, image.file.length) //make here a loop on
very large files
zos.closeEntry()
}
Cheers

[Lift] Re: YA menu question: separate menus
Derek,
I'd love to test the changes you made to Menu, but my build fails when
I run
mvn install on the pom in the lift directory of the download from
http://github.com/dpp/liftweb/tree/wip-dcb-menu-addons
Here's what maven reports:
[WARNING] Warning in manifest for net.liftweb:lift-webkit:jar:1.1-
SNAPSHOT : Did not find matching r
eferal for org.slf4j.*
[ERROR] Error in manifest for net.liftweb:lift-webkit:jar:1.1-
SNAPSHOT : The default package '.' is
not permitted by the Import-Package syntax.
This can be caused by compile errors in Eclipse because Eclipse
creates
valid class files regardless of compile errors.
The following package(s) import from the default package
[net.liftweb.http, net.liftweb.http.auth, n
et.liftweb.http.js, net.liftweb.http.js.jquery, net.liftweb.sitemap]
[ERROR] Error(s) found in manifest configuration
[INFO]
[ERROR] BUILD ERROR
[INFO]
[INFO] Error(s) found in manifest configuration
It seems like a problem with the construction of the following
plugin in the pom.
org.apache.felix
maven-bundle-plugin
!
net.liftweb.util.*,net.liftweb.*;version="${pom.version}"
org.slf4j.*;resolution:="optional",*
*
Either that, or there's something else going on. Any ideas?

My error. Ignore this. I did a mvn clean then mvn install outside

[Lift] Re: YA menu question: separate menus
Derek,
Your new Menu snippet works great. I created a superfish-style menu
using
a list of groups, like so:
object MenuWidgetEx {
def apply(groups:List[String]) = new MenuWidgetEx(groups,
MenuStyle.HORIZONTAL, JsObj()) render
def apply(groups:List[String], style: MenuStyle.Value) = new
MenuWidgetEx(groups, style, JsObj()) render
def apply(groups:List[String], jsObj: JsObj) = new MenuWidgetEx
(groups, MenuStyle.HORIZONTAL, jsObj) render
def apply(groups:List[String], style: MenuStyle.Value, jsObj:
JsObj) = new MenuWidgetEx(groups, style, jsObj) render
}
class MenuWidgetEx(groups:List[String], style: MenuStyle.Value, jsObj:
JsObj) extends
MenuWidget(LiftRules.siteMap open_!, style: MenuStyle.Value, jsObj:
JsObj){
override def render :NodeSeq = {
def buildMenu(group:String) =
head ++
{for(group <- groups) yield {buildMenu(group)}}
}
Someone should redo the MenuWidget snippet to handle your
new Menu.builder construct, so it doesn't have to be subclassed.

[Lift] Lift Shopping Cart?
I am experimenting with Lift / Scala and am thinking about using it for some projects in the future. Really like it. For a website I need shopping cart functionality. In last years post 'Making modular lift functionality' I read about plans for making a Lift shopping cart module. What is the status of this project? Is there a shopping cart example / project available which I can use / look at? Same question for a user Forum in Lift, is there a Lift Forum module? regards, David Persons --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: Lift Shopping Cart?
The paypal module simply covers transactional integration - there is no support for paypal shopping cart. You could of course write your own shopping car JAR and just hook that into lift any which way you would like.

[Lift] URL Rewriting problem
RewriteRequest isn't working in my app, so I must be doing something
wrong, or leaving something important out.
I have a menu in my siteMap:
Menu(Loc("contact", List("info", "contact"), "Contact Us", LocGroup
("info")))
My boot.scala contains this:
LiftRules.rewrite.append {
case RewriteRequest(
ParsePath(List("info","contact"),_,_,_),_,_) =>
RewriteResponse("content" :: Nil, Map("tag" ->
"contact"))
...
}
And I have a content.html page in webapp.
Clicking on the "Contact Us" menu returns an HTTP 403 error, not
content.html.
Any help would be appreciated.

[Lift] Re: URL Rewriting problem
Do you have a menu item that matches List("content")? If not, that's why
you're getting the 403. If you use SiteMap it has to be exhaustive for all
content on your site. Anything that doesn't match as SiteMap entry will get
a 403 error like you got here. If you don't want to show a menu item for a
particular page (probably in this case), use a Hidden Menu:
Menu(Loc("content", List("content"), "Internal Content", Hidden))

[Lift] Re: URL Rewriting problem
David,
Here's my scenario. I've got about 30 menus organized into about 7 or
8 groups. Thanks to
help from you and Derek and others in this discussion, I can display
nested menus in
groups as a horizontal superfish menu.
Using URL Rewriting, as described in the master lift book, I created a
method:
def rewrite:LiftRules.RewritePF = {
//Services
case RewriteRequest(
ParsePath(List("services"),_,_,_),_,_) =>
RewriteResponse("content" :: Nil, Map("tag" ->
"services"))
case RewriteRequest(
ParsePath(List("services","coreguard"),_,_,_),_,_) =>
RewriteResponse("content" :: Nil, Map("tag" ->
"coreguard"))
case RewriteRequest(
ParsePath(List("services","estatePlanning"),_,_,_),_,_) =>
RewriteResponse("content" :: Nil, Map("tag" ->
"estatePlanning"))
case RewriteRequest(
...
}
That sends all my requests to a content.html template:
The snippet is just as riduculously simple:
def content(xhtml:NodeSeq):NodeSeq = {
val c = S.param("tag") openOr ""
bind("c", xhtml,
"title" -> S.?(c))
}
This navigation works, though is repititious.
It would be relatively easy to extend this idea to generate menus,
complete with navigation, programatically (say, from an xml file or a
data table) and allow
site administrators and other users to drag-and-drop menus as desired.
The point of all this, in my view, is to eventually populate
content.html with data/documents/templates/atom feeds, whatever, with
nothing
more than the RewriteResponse Map parameter, and voila, you have a
fledgling CMS built with relatively few lines of code.
If you have some alternative ideas for creating a programatic
navigation system, I would be very interested.
Glenn...

[Lift] Re: URL Rewriting problem
So, you want custom content with menus generated from the database...
well...
class BaseContentLoc(val name: String, _aspect: String) extends
Loc[CustomContent] {
// the name of the page
// def name = "Content"
val BaseAspect = _aspect
def defaultParams = Full(ContentLocStuff.NullCustomContent)
override def forceParam = defaultParams
// the default parameters (used for generating the menu listing)
override def additionalKidParams =
CustomContent.findAll(By(CustomContent.aspect, BaseAspect),
OrderBy(CustomContent.displayOrder, Ascending))
// no extra parameters
def params = List(Loc.PlaceHolder, Loc.Template(myTemplate))
def myTemplate() =
/**
* Generate a link based on the current page
*/
val link =
new Loc.Link[CustomContent](List(BaseAspect), false) {
override def createLink(in: CustomContent) = {
Full(Text("/"+urlEncode(BaseAspect)+"/"+urlEncode(in.page)))
}
}
/**
* What's the text of the link?
*/
val text = new Loc.LinkText(calcLinkText _)
def calcLinkText(in: CustomContent): NodeSeq = {
if (in.page.length > 0) Text(in.page) else Text(name)
}
object Finder {
def unapply(page: String): Option[CustomContent] =
CustomContent.findContent(page, BaseAspect)
}
/**
* Rewrite the request and emit the type-safe parameter
*/
override val rewrite: LocRewrite =
Full({
case RewriteRequest(ParsePath(BaseAspect :: Finder(content) :: Nil,
_, _, _), _, _) =>
(RewriteResponse(BaseAspect :: Nil), content)
})
/**
* Check for page-specific snippets and
* do appropriate dispatching
*/
override val snippets: SnippetTest = {
case ("display", Full(v)) => display(v) _
}
def display(v: CustomContent)(in: NodeSeq) = v.content openOr in
}
This will autogenerate submenus based on a DB lookup of CustomeContent.
Does this help achieve your longer term goal?
Thanks,
David

[Lift] Lift and Scala for Non-Java Programmers
Hi guys, I know this is more a Scala question than a Lift one but I do all my web programming within frameworks and I find it's easiest to learn a language when doing a real project... Are there any tutorials, let alone good ones, introducing Scala (and Lift) to programmers with no knowledge or interest in Java? I've seen several introductions to Scala for Java programmers (Scala for Java Refugees and Alex Blewitt's articles look particularly in- depth) but next to nothing for people with other backgrounds. I know that most Scala people are coming from Java but I would imagine that there is something for us coming from beyond the Java world. As for me, I've done a lot of stuff in PHP (CakePHP) and Python (Pylons, Django) and have spent the last six months mostly doing front- end work in Javascript. Basically I'm a quick and dirty interpreted language coder and I'm now looking at Scala because I believe my next project will demand (near) real-time performance that I don't think I'd be able to get in my usual languages. Lift looks like a really nice framework and its Comet, XMPP and OSGI integration are things I will most likely use in the project. As somewhat of an aside, I'd like to add my two cents about the existing tutorials. The To Do tutorial was quite nice and a great introduction to Lift but didn't leave me at the point where I'm be comfortable writing my own stand-alone code. I wanted to then do the PocketChange tutorial (thanks for putting the PDF of the book online!) but it's way too high-level for me and glosses over a bunch of stuff. For instance, "import ... standard imports ..." is very unhelpful for me – I still don't know what are the standard Lift imports! Finally, the tutorial code snippets on the wiki are very useful. Like I said, I understand that I'm looking for more a Scala tutorial than a Lift one but I appreciate any links and suggestions. Thanks for the great work on the project and as I make progress in my learning I promise to write up my experiences!

[Lift] Re: Lift and Scala for Non-Java Programmers
Peter, If you want to learn enough Scala to make Programming in Scala a good read, I'd like to suggest my book, Beginning Scala. While it does do some comparison between Scala and Java, it does so with two goals: (1) to use Java as a generic OO-ish language and (2) to show how Scala's syntax and features makes writing type-safe code much more efficient. If you know Python and JavaScript, I think the book will be your speed.

[Lift] Re: Wolfram Alpha integration for Lift
Tim, Thanks for the prompt. Can you point me to a description of what's possible with W|A? i can put together a draft that you can then rev.

[Lift] Mapper record deletion
As I move deeper into learning Lift, I now want to start deleting
Mapper records in the ToDo example.
My first problem is how to get an ECMAscript or jQuery 'Confirm
delete' dialog to actually delegate an affirmative 'OK' button click
to the deletion, and conversely, to do nothing for the 'Cancel'
action.
Right now, both just fall through to the default:
toShow.flatMap(td => bind("todo", html, "delete" -> link("/todo", ()
=> td.delete_!, )% ("onclick" ->
"confirm();") , "check" -> ...
Thanks!
