[Lift] Re: lift views
Yoryos, You probably missed the part where you can add a head element inside the surround tags and it will replace the default element: lift:surround with=default2 at=content head titleA better title than the one in default.html/title /head h2Welcome to your project!/h2 plift:helloWorld.howdy //p /lift:surround I don't see that duplicating the html and body tags unnecessarily makes it any better. Just adds clutter, IMO. The fewer tags I have to deal with, the easier it is to read. Chas. valotas wrote: Hi all! Just a proposal: wouldn't be better to have the views look like more an html page.

[Lift] Re: Lift does not display templates as described in the book.
Try posting your conceptual questions to the list. Maybe folks here can help, and once we understand what you need, we can look into providing some documentation to support it. No book can fill all needs. Lots of people just want clear examples and can go from there. The Lift book addresses that need very well, I think. But hopefully we'll have more Lift books soon, each taking a slightly different approach to learning Lift. I'd love to contribute to one, but I'm still trying to learn Lift myself. Specific suggestions always welcome. Chas. Sean Reque wrote: Concrete examples are a great teaching tool, but unless you eventually teach the concepts behind the examples, your students are incapable of applying their knowledge to do anything beyond what they can glean from the examples example. It's like teaching math purely through example with no theory: your students may be able to pass your tests, but they won't understand what they are doing and come next year they won't be able to build on what they learned. I'm finding the lift book sorely lacking in teaching concepts, and because of that I'm having an all but impossible time learning what is actually possible in lift. I I am not the kind of programmer that just copies and pastes other peoples' examples. I want to understand my tool and use it to it's fullest potential. When the lift book describes how pages are rendered, as if teaching a concept, and leaves out essential details like what scope templates are actually searched in, how am I supposed to understand how Lift works without posting to this mailing list or reading the source code? I wasted a couple of hours reducing my problem down to the simplest test case, and this is not the first time since learning lift where I've wasted so much time only to learn that either something doesn't work or doesn't work the way I thought. I'm pretty sure that had I picked rails or django for my pet project I would have been done already. Is it simply that Lift is too cutting edge for me? Am I the only one wasting hours of time learning how Lift and other Java tools work rather than getting my app written? I'm sorry if I sound frustrated. It is not just Lift I am struggling with. It's the whole stack I'm trying to learn! I am just getting immersed into the Java world again during my spare time. JAXB (especially JAXB!), buildr/maven/ant, Jetty, Scala and it's Eclipse plugin, Lift, each one of these tools has taken up hours of my time as I struggle to do what I thought I could do easily by reading about the tool or reading the tool's documentation. I am grateful for your response though and will take time to learn more about what the sitemap means in Lift. - Sean Reque On May 30, 2:56 pm, marius d. marius.dan...@gmail.com wrote: To access a page you need to add it in the SiteMap. I assume you are a bit confused about the relation between a Menu and a page. I mean after all maybe for your site you don't really need a menu but in Lift a Menu is much more then a visual representation of a way to navigate to your pages. It specifies various things such as how to access a page (constraints definition), visibility of a page in the sitemap Menu etc. So in short the SiteMap + Menu + Loc describes how pages can be accesses in a Lift app. The Lift book describes that by the means of concrete examples, detailed Menu Loc descriptions etc. Maybe some things in the book are not very obvious for a first read or just reading it as ultimatelly learning Lift is about coding trying things. The book is just a mean to an end, I would say. Br's, Marius On May 30, 9:38 pm, Sean Reque seanre...@gmail.com wrote: I have the pocketchange app with lift 1.0. I add a directory in webapp with an index.html file, identical to the help directory except with some changed text. I visit the URL corresponding to the directory and it doesn't show up at all, but tells me the requested resource is not found. I then add the directory index.html file to the global sitemap in Boot.scala the same as it's help counterpart, recompile and restart jetty, and suddenly, without even using or touching the sitemap, lift displays the processed template. I've read the template finding algorithm described in the exploring lift book and it makes no mention of any such requirement, and I'm pretty sure I shouldn't have to add every single template file to the global sitemap to get lift to even recognize it's existence.

[Lift] Re: JavaScript interface to Comet
Yes looks like this is exactly what you would need. Please see partialUpdate from CometActor. As an example you can see sites/example/ src/main/scala/net/liftweb/example/comet/Clock.scala. partialUPdate function returns a JsCmd but there are of course implicit conversions between JsExp and JsCmd. What you're trying to do seems like an interesting thing for a Lift demo app in the sense that it would provide an interesting visual effect through CometActor.

[Lift] Re: lift views
Agreed with Tim. I also don't see any value.

[Lift] Strange behavior of RequestVar
Compare two cases. First:
class SnippetName {
object oVar extends RequestVar(O.create)
def processAdd(o: O) { ... }
def add(xml: NodeSeq): NodeSeq = {
bind (f, xml,
field - SHtml.text(oVar.is.field, oVar.is.field(_)),
submit - SHtml.submit(Submit, () = processAdd(oVar.is)
)
}
}
And the second case:
class SnippetName {
object oVar extends RequestVar(O.create)
def processAdd(o: O) { ... }
def add(xml: NodeSeq): NodeSeq = {
val o = oVar.is // CHANGES STARTS HERE
bind (f, xml,
field - SHtml.text(o.field, o.field(_)),
submit - SHtml.submit(Submit, () = processAdd(o)
)
}
}
In firts case all works fine, but in second case data not retained
across submit trying. Why?

[Lift] date management
As I proceed to enhance the ToDo example, I have added a new field to
the ToDo.scala model:
object dueOn extends MappedDateTime(this) {
final val dateFormat = DateFormat.getDateInstance
(DateFormat.SHORT)
override def asHtml = Text(dateFormat.format(is))}
Next, I added a binding in the TD.scala snippet within the add method
of the TD class:
def doBind(form: NodeSeq) = {
bind(todo, form, desc - todo.desc.toForm,
priority - todo.priority.toForm,
dueOn - todo.dueOn.toForm,
submit - submit(create new Task,
checkAndSave)}
Then, the todo.html template gets a bind point:
lift:TD.add form=post
...
todo:dueOn/
todo:submitbutton//todo:submit
/lift:TD.add
When I check the database, the record does save, and all the other
fields are OK, but the date itself is null.
Somehow, it seems the text of the input field is not getting changed
into a Date object for the database to handle, right?
When I look at the PocketChange app from the book, everything is done
completely differently from the ToDo example (no use of _toForm, for
instance).
I know dates and times are convoluted in Java, so what am I missing?
Thanks!

[Lift] Re: lift views
Folks, There's nothing that Lift does magically with lift:surround/ or lift:embed/ They just replace XML nodes. If you want to structure your apps to not have surround or embed, that's fine. If you want to surround or embed at different points in your files, totally cool. Do it however you want. It makes no difference to Lift. Lift's templating is just an XML substitution system. Substitute or don't at your pleasure. Do what works best for you. It makes no difference to Lift. Thanks, David On Sun, May 31, 2009 at 11:31 AM, Yoryos valo...@gmail.com wrote: No!

[Lift] Re: Showing a Box or Redirecting?
class SomeSnippet {
implicit def boxOpener(in: Box[NodeSeq]): NodeSeq = in openOr
{S.error(Inactive); S.redirectTo(S.referer openOr /)}
def showA(xhtml: NodeSeq): NodeSeq =
for {
id - S.param(id)
info - session1.get(id)
} yield bind(foo, xhtml, thing - info.x)
}
The implicit makes the Box[NodeSeq] turn into a NodeSeq or redirects the
user.
Thanks,
David
