[Lift] Re: Menu generated from database?
Hi David,
Since I am programming a CMS for my client, I need my lift menu to
come from the database.
LiftRules.setSiteMap(SiteMap(MenuInfo.menu :_*))
def menu: List[Menu] =
{
Log.info(Menu called)
...
It seems my menu function only gets called once, on subsquent calls I
do not get any log message.
Maybe I have to subclass SiteMap?
Can you point me in the right direction?
Thanks, Philip

Hi,
How can I get a Liftweb menu to be generated from database content?
Alternatively, can the menu come from a XML datasource? could I load/
serialize from that?
Could it change dynamically at any time?

Re: [Lift] Maper SQL stored procedures
Marcin, Back in SmartMode days (a Java-based precursor to Lift) we bound methods to stored procedures, but it was pretty costly dev-wise in terms of abstracting the way each RDBMS deals with stored procedures. If you (or someone else) has a nice abstraction of stored procedures that's type safe, let's see if we can add it to Lift.

An item is valid if and only if at least one of the brand name is non-
empty.
But from the lift example, field validation is done by overriding the
validations method of each field and the validate method of the
LongKeyedMetaMapper will invoke all validations method of its fields
and return the list of FieldError if any.
Is there anyway to implement my requirement in lift Mapper with
something like (Sorry for my bad lift syntax, still learning :) )
def isValidItem = {
if ( (chiBrandName eq null) || chiBrandName.length == 0)
(engBrandName eq null) || engBrandName.length == 0) )
// show the field error
else Nil

But could lift REST APIs wrap the lib to provide more Liftesque API? It's more of a return-type issue. The reason I created Box in the first place is that Option doesn't give you the ability to capture reasons for None (yeah, there's Either... although there wasn't when I introduced Box [Can at the time], but you can't use Either in a for comprehension). In reviewing the JSON code, there's actually nothing that I'd change in the APIs. I would support Box everywhere there's support for Option (serializing/deserializing and implicit helpers).

[Lift] Looking for the single person who owns naming in Lift
Folks, There has been a lot of talk about method/class naming in Lift lately. It's a good thing(tm) to normalize method and class naming in Lift. But it's also important that after the initial cleanup is done, the consistency is kept going forward. It's also important that there's a pair of eyes looking at code as it's evolving and getting the names right early. For example, the common Actor stuff was floating around for 6 weeks (and very publicly so) before we rolled it into Lift. Jonas and I were the only ones that commented on the code. We got it to where we liked it and pushed it into master... then people made suggestions about the names. This is the wrong time. As important APIs are evolving, it's important to get the names right before people start using the code. So, I'm asking for someone in the community to step forward and own naming in Lift. You may choose to have commit rights to the Lift code or not, but you will be responsible for: - Understanding most (all?) of the Lift modules such that the person has a broad understanding of the pieces of Lift - Organizing a set of change recommendations for name changes and deprecations - Soliciting community involvement and feedback on the recommendations - Finalizing the recommendations for the next release of Lift (whether that's called 1.1 or 2.0) - Doing ongoing review of material additions to Lift to make sure things are consistent So, if you're interested in that role (and it's a non-trivial time commitment over the next 6 weeks), please contact me off-list and let's chat.

[Lift] Lift on Azure
Java apps have gotten a lot easier to run on Azure this week. Here's a video on developing a simple app with Eclipse and deploying in Tomcat on Azure: http://microsoftpdc.com/Sessions/SVC50 I don't believe Java on Azure has the same restrictions as Java on GAE. For example, you can write to the local filesystem and use threads. Using the REST-based Azure Tables datastore (non-RDBMS) with Lift's ORM might be tricky, but SQL Azure is available via JDBC. Or, as far as I know Derby should work. I think you need to be on Windows to develop though, even though the example in the video just uses Eclipse. For one thing, the desktop version of Azure is Windows-only. -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] A sensible AJAX approach
Classic use case: a user chooses to view/edit and object by clicking on a link. This causes the app to fetch an edit view (form) and render it asynchronously, probably rendering it as a modal dialog. To specify the case a bit more, consider a table of like objects that allows you to edit them (orders or accounts). As far as the user experience, clicking edit for one would yield the same edit form as any other - only the contents (the target of the edit) would change. Normal ajax forms in lift are simple - just wrap the bind in an ajax form (http://is.gd/4Z61Z) and you get an async submit with essentially the same template code. But what about ajax forms delivered by ajax? What's the best way to implement this in lift? It seems like there are two routes: client and server-based. 1) In the client-based approach, I can declare an invisible form in the template, as well as write some static javascript to do the heavy lifting (no pun intended). This JS would be responsible for receiving the data representing the object to edit from the server as json, unpacking it into the form for editing, rendering the form, handling the submit as ajax, and finally hiding the form. This means writing a good bit more JS by hand, but it keeps the (compiled) snippet code smaller. Ordinarily I'd see that as good, but more and more snippets seem like they are intended for such heavy view meddling. 2) The server-based approach would require very little of the main template: basically just a containing element (w/ dom id) to host the delivered form. The snippet itself would yield a form on an ajax call via SetHtml. It would also have to set up the handlers and populate the form contents with the target object. This is the part that I'm not clear on. I know I can just inline the XML with bind points as if it were in a form, but that just feels strange. Would it make more sense to use an external template, similar to a rails partial? Is there a template loading facility for this?

JArray is a case class that wraps a List. It's not an array-of-list or
anything, just that the actual elements are stored in a List that
JArray holds.

[Lift] How can one bind attribute values in a snippet?
For example, if my html template looks like this: lift:surround with=default at=content h2foobar/h2 lift:MySnippet.render img src=dummy/ /lift:MySnippet.render /lift:surround In my snippet I'd like to replace dummy (in img src) with a real value. I'm sure there are other ways to output img tags with attribute values, but I'm specifically interested in this general case: writing the presentation in the template, and filling in the attribute value from code.

Re: [Lift] A sensible AJAX approach
Chris Lewis burningodzi...@gmail.com writes:
Classic use case: a user chooses to view/edit and object by clicking on
a link. This causes the app to fetch an edit view (form) and render it
asynchronously, probably rendering it as a modal dialog. To specify the
case a bit more, consider a table of like objects that allows you to
edit them (orders or accounts). As far as the user experience, clicking
edit for one would yield the same edit form as any other - only the
contents (the target of the edit) would change.
Seems you're a few steps ahead of me. I'll be looking at basically the same
use case soon :-)
Normal ajax forms in lift are simple - just wrap the bind in an ajax
form (http://is.gd/4Z61Z) and you get an async submit with essentially
the same template code.
But what about ajax forms delivered by ajax? What's the best way to
implement this in lift? It seems like there are two routes: client and
server-based.
Agreed
1) In the client-based approach, I can declare an invisible form in the
template, as well as write some static javascript to do the heavy
lifting (no pun intended). This JS would be responsible for receiving
the data representing the object to edit from the server as json,
unpacking it into the form for editing, rendering the form, handling the
submit as ajax, and finally hiding the form.
This means writing a good bit more JS by hand, but it keeps the
(compiled) snippet code smaller. Ordinarily I'd see that as good, but
more and more snippets seem like they are intended for such heavy view
meddling.
Probably depends on the app. If it's mostly a single-url, js based app
this would work. Personally (and since I'm not a JS ninja :-) I try to
limit the amount of client side code to the where it makes sense. I
think the development experience (for me) is better with a statically
typed languagne (tdd etc).
2) The server-based approach would require very little of the main
template: basically just a containing element (w/ dom id) to host the
delivered form. The snippet itself would yield a form on an ajax call
via SetHtml. It would also have to set up the handlers and populate the
form contents with the target object.
This is the part that I'm not clear on. I know I can just inline the XML
with bind points as if it were in a form, but that just feels strange.
Would it make more sense to use an external template, similar to a rails
partial? Is there a template loading facility for this?
I've been doing this (external templates) and it works great. Very easy
for designers to modify layout etc.
Here's a simple example the changes several page elements when a select
is changed:
bind(select, in,
type - ajaxSelectObj(reportTypes, currentType.is,
(f:ResultF) = {
currentResult(Empty)
currentType(Full(f))
val nodeseq =
TemplateFinder.findAnyTemplate(List(tender, results)).open_!
SetHtml(comparison, resultComparison(tender,
chooseTemplate(lift, tender.result_comparison, nodeseq)))
SetHtml(summary, segmentSummary(tender,
chooseTemplate(lift, tender.segment_summary, nodeseq)))
})
)
Here the two elements are read from the same template file but it could
easily be split...

[Lift] Re: How can one bind attribute values in a snippet?
Thanks Jeppe, that looks like what I need.
I'm having trouble following your example though, what are res,
filteredResult, lc, etc? My code looks like this right now:
def render( xhtml: NodeSeq ): NodeSeq {
items.flatMap( f =
bind(item, xhtml,
name - item.name
)
}
so presumably I'd need to add to that to bind an attribute called
value:
def render( xhtml: NodeSeq ): NodeSeq {
items.flatMap( f =
bind(item, xhtml,
name - item.name,
AttrBindParam(value, item.value)
)
}
bind(values, in,
BindNumber(tco,
res.filteredResult(lc).avgTCO(segment)),
AttrBindParam(rankClass,Text(rankClass(res.rankBySegment(lc, segment))),
class)
)

[Lift] JRebel: implements new interfaces and could not be reloaded!
Anyone got any tips on working around this error?
JRebel: Class 'com.blah.blah.explorer.snippet.Features$$anonfun$render
$1' implements new interfaces and could not be reloaded!
I've just tried JRebel for the first time, and I made what I thought
was a minor change to my snippet and JRebel wasn't able to reload it.
The change I made was to uncomment the sort line in this snippet:
class Features {
def render( xhtml: NodeSeq) : NodeSeq = {
Server.store
.classes
//.sort( (c1,c2) = c1.name.toString c2.name.toString)
.flatMap( c =
bind(feature, xhtml,
name - c.name
)
)
}
}

Re: [Lift] JRebel: implements new interfaces and could not be reloaded!
Unfortunately, JRebel is sensitive to certain kinds of changes;
changes to the names of the generated classes for function literals is
one of them. In this case, since you've got two function literals in
the class, their names are something$1 and something$2 or equivalent.
After commenting out the line, the second one is now something$1,
which has a totally different interface.
You can work around it if you really want to, but it's probably easier
(or at least prettier code) to just restart the server.
Also, just stylistically, that commented line could be:
//.sort(_.name.toString _.name.toString)

Re: [Lift] A sensible AJAX approach
Thanks for the feedback Jeppe. I can't completely infer the context of
your example, but I get the idea (and I hadn't known about
TemplateFinder). Here's what I've hacked together so far.
In my normal snippet, I have a render loop that binds orders to template
names. One of the bind points looks like this:
..
label - SHtml.a(viewOrder _, Text(View)),
..
Here, viewOrder is a function called by ajax, so a () = JsCmd. I've
defined it as follows (assume i've imported TemplateFinder.findAnyTemplate):
def viewOrder(): JsCmd = {
SetHtml(order, SHtml.ajaxForm(
bind(order, findAnyTemplate(List(orders/_edit_order)).open_!,
orderNo - Text(order.orderNo),
submit - SHtml.submit(submit, () = println( -- submit!))
) ++ SHtml.hidden(() = println( -- submit!))
))
}
Using the usual ajaxForm technique, I wrap the result of a bind which
results in the contents passed to SetHtml. The funny part is that I
directly load a template file as a NodeSeq and use that as the arg to
bind. That template file doesn't call a snippet, but it uses the bind
points bound in the call - and it works! Here's the full _edit_order.html:
div
order:orderNo/
order:submit/
/div
It's just raw xml. No snippet calls, yet bind still processes it
correctly - even the ajax wiring! I think this is all in all a pretty
good way to handle the common-edit-dialog problem, and certainly the
cleanest I've seen yet. I wonder though, is it intentional that bind
points work when not explicitly wrapped in a snippet call tag?
thanks!

Chris Lewis burningodzi...@gmail.com writes:
Classic use case: a user chooses to view/edit and object by clicking on
a link. This causes the app to fetch an edit view (form) and render it
asynchronously, probably rendering it as a modal dialog. To specify the
case a bit more, consider a table of like objects that allows you to
edit them (orders or accounts). As far as the user experience, clicking
edit for one would yield the same edit form as any other - only the
contents (the target of the edit) would change.
Seems you're a few steps ahead of me. I'll be looking at basically the same
use case soon :-)
Normal ajax forms in lift are simple - just wrap the bind in an ajax
form (http://is.gd/4Z61Z) and you get an async submit with essentially
the same template code.
But what about ajax forms delivered by ajax? What's the best way to
implement this in lift? It seems like there are two routes: client and
server-based.
Agreed
1) In the client-based approach, I can declare an invisible form in the
template, as well as write some static javascript to do the heavy
lifting (no pun intended). This JS would be responsible for receiving
the data representing the object to edit from the server as json,
unpacking it into the form for editing, rendering the form, handling the
submit as ajax, and finally hiding the form.
This means writing a good bit more JS by hand, but it keeps the
(compiled) snippet code smaller. Ordinarily I'd see that as good, but
more and more snippets seem like they are intended for such heavy view
meddling.
Probably depends on the app. If it's mostly a single-url, js based app
this would work. Personally (and since I'm not a JS ninja :-) I try to
limit the amount of client side code to the where it makes sense. I
think the development experience (for me) is better with a statically
typed languagne (tdd etc).
2) The server-based approach would require very little of the main
template: basically just a containing element (w/ dom id) to host the
delivered form. The snippet itself would yield a form on an ajax call
via SetHtml. It would also have to set up the handlers and populate the
form contents with the target object.
This is the part that I'm not clear on. I know I can just inline the XML
with bind points as if it were in a form, but that just feels strange.
Would it make more sense to use an external template, similar to a rails
partial? Is there a template loading facility for this?
I've been doing this (external templates) and it works great. Very easy
for designers to modify layout etc.
Here's a simple example the changes several page elements when a select
is changed:
bind(select, in,
type - ajaxSelectObj(reportTypes, currentType.is,
(f:ResultF) = {
currentResult(Empty)
currentType(Full(f))
val nodeseq =
TemplateFinder.findAnyTemplate(List(tender, results)).open_!
SetHtml(comparison, resultComparison(tender,
chooseTemplate(lift, tender.result_comparison, nodeseq)))
SetHtml(summary, segmentSummary(tender,
chooseTemplate(lift, tender.segment_summary, nodeseq)))
})
)
Here the two elements are read from the same template file but

[Lift] Re: JRebel: implements new interfaces and could not be reloaded!
Damn. I guess there is no free lunch :)
Thanks for the response Kris, and the stylistic tips! I am easing my
way into scala, starting with the more verbose syntax and picking up
shortcuts as I get more familiar with stuff!

Unfortunately, JRebel is sensitive to certain kinds of changes;
changes to the names of the generated classes for function literals is
one of them. In this case, since you've got two function literals in
the class, their names are something$1 and something$2 or equivalent.
After commenting out the line, the second one is now something$1,
which has a totally different interface.
You can work around it if you really want to, but it's probably easier
(or at least prettier code) to just restart the server.
Also, just stylistically, that commented line could be:
//.sort(_.name.toString _.name.toString)

I've just tried JRebel for the first time, and I made what I thought

The change I made was to uncomment the sort line in this snippet:
class Features {
def render( xhtml: NodeSeq) : NodeSeq = {

.classes
//.sort( (c1,c2) = c1.name.toString c2.name.toString)

[Lift] JPA and eager fetch
Newbie Lift / JPA alert!
I am sure I am doing something dumb here, but I can't quite figure it
out. I have a JPA project (modelled after the lift JPA demo app).
I have an object with a one-to-many association, and I want to eager
fetch the collection. It is declared like :
@OneToMany(){ val targetEntity = classOf[OpenIdUser], val cascade =
Array(CascadeType.ALL), val fetch=FetchType.EAGER}
var openIds : _root_.java.util.Set[OpenIdUser] = new
_root_.java.util.HashSet[OpenIdUser]()
In my spa persistence unit, eager fetching works fine from the unit
test. The unit test uses plain old emf factory instances.
However, from my web application (run with jetty:run) and using
Model.createNamedQuery, or Model.find, only the parent object is
fetched. The collection is not.
I gather this has something to do with the way that Model works? Or
are my annotations being ignored when they are packed in a .jar file?
Clues would be appreciated.
Thanks
Warren

Re: [Lift] A sensible AJAX approach
On Thu, Nov 19, 2009 at 2:52 PM, Chris Lewis burningodzi...@gmail.com wrote:
Classic use case: a user chooses to view/edit and object by clicking on
a link. This causes the app to fetch an edit view (form) and render it
asynchronously, probably rendering it as a modal dialog. To specify the
case a bit more, consider a table of like objects that allows you to
edit them (orders or accounts). As far as the user experience, clicking
edit for one would yield the same edit form as any other - only the
contents (the target of the edit) would change.
Normal ajax forms in lift are simple - just wrap the bind in an ajax
form (http://is.gd/4Z61Z) and you get an async submit with essentially
the same template code.
But what about ajax forms delivered by ajax? What's the best way to
implement this in lift? It seems like there are two routes: client and
server-based.
1) In the client-based approach, I can declare an invisible form in the
template, as well as write some static javascript to do the heavy
lifting (no pun intended). This JS would be responsible for receiving
the data representing the object to edit from the server as json,
unpacking it into the form for editing, rendering the form, handling the
submit as ajax, and finally hiding the form.
This means writing a good bit more JS by hand, but it keeps the
(compiled) snippet code smaller. Ordinarily I'd see that as good, but
more and more snippets seem like they are intended for such heavy view
meddling.
2) The server-based approach would require very little of the main
template: basically just a containing element (w/ dom id) to host the
delivered form. The snippet itself would yield a form on an ajax call
via SetHtml. It would also have to set up the handlers and populate the
form contents with the target object.
This is the part that I'm not clear on. I know I can just inline the XML
with bind points as if it were in a form, but that just feels strange.
Would it make more sense to use an external template, similar to a rails
partial? Is there a template loading facility for this?
Thanks for any and all input.
chris
I use the second style, to great effect, in Lift - except I use
net.liftweb.http.TemplateFinder.findAnyTemplate to get the NodeSeq
representing the template instead of inlining the XML, and then use a
normal call to bind. It works a treat.
There are a couple of utility traits that I use to make this even
cleaner; I don't have time to detail how they're used at the moment
but maybe you can get a little bit of an idea by looking at the types.
One of these days I'll clean these up into something truly reusable
(these rely on the bindings stuff I detailed on my blog at
http://logji.blogspot.com/2009/09/composable-bindings-in-lift.html
with a couple of extra things, tbind and the Templated trait.
def tbind(x: Binding with Templated): NodeSeq = x.bind(x.template)
trait Templated {
def template: List[String]
}
trait Form[T] {
def onSubmit: Unit = process
def process: T
}
trait FormSnippets {
this: StatefulSnippet =
var actionBinding: Binding with Templated = _
var editFormBinding: Binding with Templated = _
lazy val dispatch: DispatchIt = {
case actionSelect = actionBinding
case editForm = editFormBinding
}
def ajaxify(b: Binding with Templated with Form[_],
clientOnSubmit: JsCmd, serverRedirect: Option[String]) = new Binding
with Templated {
override val template = b.template
override def apply(xhtml: NodeSeq): NodeSeq = {
def serverOnSubmit: JsCmd = {
b.onSubmit
serverRedirect.map(where = RedirectTo(where)).
getOrElse(SetHtml(action_selector,
tbind(actionBinding)) SetHtml(edit_form, tbind(editFormBinding)))
}
ajaxForm(b.apply(xhtml) ++ hidden(serverOnSubmit _), clientOnSubmit)
}
}
}

[Lift] Re: Jetty or Tomcat, Which web container is recommended to use to deploy the Lift app ?
Hi,David Pollk! Nginx only comes with a round-robin balancer and a hash-based balancer, so if a request takes a while to load, Nginx will start routing requests to backends that are already processing requests -- as a result, some backends will be queueing up requests while some backends will remain idle. You will get an uneven load distribution, and the unevenness will increase with the amount of load subject to the load-balancer. Haproxy as a LB can: 1: Plenty of load-balancing algorithms, including a least connections strategy that picks the backend with the fewest pending connections. Which happens to be just what we want. 2: Backends can be sanity- and health-checked by URL to avoid routing requests to brain-damaged backends. (It can even stagger these checks to avoid spikes.) 3: Requests can be routed based on all sorts of things: cookies, URL substrings, client IP, etc. So, I use nginx + haproxy + tomcat(jetty).

Apache is the worst front end for this situation... it can only support a few hundred simultaneous connections before it falls over. Ngnix on the other hand can proxy tens of thousands. Jetty's continuations make it a much better choice than Tomcat. You can have thousands of open Comet request to a Jetty instance where Tomcat is capped at a couple of hundred. Once the Servlet 3.0 spec in implemented in Glassfish, etc., Lift will support 3.0 continuations and any 3.0 container will have the same scaling characteristics that Jetty currently does.
