Re: [Lift] Goals for type and method renaming for Lift 2.0 - was: Open discussion on Lift Name Calling practices
Thank you for writing this up, Naftoli. I edited the abbreviation section ... Heiko 2009/12/18 Naftoli Gugenheim naftoli...@gmail.com (Not sure why on Chrome the wiki article page is all centered. Reported it to Chrome.) Can everyone look over the article? Especially everyone quoted in it -- Kris, Jim, DPP, Heiko, and anyone who I may have missed -- can you make sure everything represents your opinion correctly? Then if there is any disagreement after everyone's opinion is clarified we need to make some decisions together. This should not take much time, but it's very valuable! Thanks. 2009/12/15 Naftoli Gugenheim naftoli...@gmail.com I compiled much of this thread into http://wiki.github.com/dpp/liftweb/about-naming-conventions in raw form. As we continue to discuss the naming goals and guidelines and vote or decide on controversial goals, that wiki page should become more consolidated and less of a copy-paste of a discussion. :) On Mon, Dec 14, 2009 at 6:32 PM, Kris Nuttycombe kris.nuttyco...@gmail.com wrote: On Mon, Dec 14, 2009 at 12:31 PM, David Pollak feeder.of.the.be...@gmail.com wrote: Folks, Lift allows developers to create web sites that are: Reliable (which includes secure) Maintainable/concise Highly interactive Easy to build High Performance Easy to on-board (initial understanding of the APIs) Lift's APIs should reflect these rank-ordered goals. Some of these goals are in tension with each other. For example, easy on-boarding (e.g., longer method names, more traditional imperative style) is in tension with concise. There's also a very diverse Lift community. I use Emacs for a lot of my Lift coding. I know folks who use TextMate for Lift coding. Having long method names assumes the use of an IDE which has name completion. Lift's APIs must serve both communities. People are coming to Lift from Java, Ruby, PHP, and other backgrounds. Assuming Scala conventions rather than a best choice for naming does a dis-service to the polygots. Further, most of Scala's API conventions except for the collections stuff is not in my opinion that well thought out or consistent. Many of Lift's APIs have evolved correctly based on actual usage patterns. For example, the initially counter-intuitive use of apply to set fields and vars works far better than any other mechanism, especially when chaining calls. I've tried many different mechanisms (e.g., update(), Pascal style :=, set(), etc.) for setting fields and the one that everybody gravitated to was apply(). We also have to consider the existing code base. I've personally got 150K lines of Lift-code under management. If we start breaking APIs without a compelling reason, it costs me money and it costs my clients less of my time. What's the impact to various different current users of Lift of breaking APIs without a compelling reason (and I like this name better than that name or this name is more consistent are not compelling reasons.) So, my criteria for any name changes (and this is not open to any type of negotiation and I've been 100% consistent about this since the discussion began) is: If the name change can be accomplished with a deprecation of the old name without breaking any existing APIs, then the name change can be the better name. If the name change is internal to Lift or is in a little-used feature (e.g., Kris's API changes in Loc) such that very few projects will likely be impacted by a name change and those that are impacted are sufficiently savvy that they will understand the change and be able to make it in a matter of minutes. Any class name or object name change that does not meet the above criteria must be compelling. For example, we changed from Scala Actors to Lift Actors. This was a substantial amount of breakage, but there were no alternatives and the Scala Actor memory retention issues were materially impacting many different sites and we had worked on various attempted solutions over a 10 month period. If we're going to break without deprecation and the breakage is going to impact a substantial part of the Lift community, there must be a compelling reason to make the breakage.

[Lift] Make it possible to add LocParams to MetaMegaProtoUser's menus
Hi, I created an issue (#251) to Make it possible to add LocParams to MetaMegaProtoUser's menus: The various user related menus are created by methods xxxMenuLoc (e.g. loginMenuLoc) which give us no flexibility to add LocParams. Why would there be a need for that? E.g. for adding a LocGroup in order to customize menu display. The idea is that there are additional methods that are called from xxxMenuLoc in order to populate the LocParams. The default implementation will add a LocGroup(user). Before implementing that I would like to ask for you opinion.

[Lift] Re: (Maybe bug)comet long polling into javascript loop?
This is not a bug. When Lift detects multiple requests for the same session it breaks out the Comet request. This is a safety mechanism in order to avoid HTTP connection starvation on the client side. This is because browsers have a very limited connection pools and the number of parallel HTTP connections are quite low varying from 2 to probably 8 depending on the browser. Note that this pool is shared among different tab browsers AND different instances of the same browser. So if you want to test with multiple browsers on you dev env use different browsers such that open your app with Firefox, then open the same app with Chrome etc. Br's, Marius On Dec 18, 11:34 am, Andrea Peruffo a.peru...@mcmspa.it wrote: I have a project where a snippet generates the code for a comet actor, but when I open two(or more) windows of the same browser on the page I can see that javascript on both pages start to makes continuous comet calls.

On Fri, Dec 18, 2009 at 1:58 AM, Andrea Peruffo a.peru...@mcmspa.it wrote: And this does not affect performances? or server side computations? The short answer is that it does increase the amount of HTTP traffic, but with HTTP keep-alive, that's not a lot of new TCP/IP connections. On the server side, Lift does its Comet support very early in the HTTP request/response cycle and the computations for handling the setup/tear down of the Comet long poll and minimal. If you have an actual application that has actual performance issues related to this, there are things that can be done: - You can use DNS wildcarding to sent the Comet long poll requests to a different, random host and this will allow more than 2 HTTP requests to the same server because the browser logic is based on the host name. - You can include your own logic for when a Comet long poll operation is terminated But (and I say this based on many years of experience deploying Lift-based Comet apps and interacting on this list and privately with folks who have built Lift apps), it's never been an actual production issue and there are plenty of folks using Lift and Lift's comet long polling in production for non-trivial applications.

Re: [Lift] stable identifier required - problems with rewriting requests
For stable identifers, see the Scala Language Specification, section 8.1.4:
http://www.scala-lang.org/sites/default/files/linuxsoft_archives/docu/files/ScalaReference.pdf
You can also see this discussion:
http://old.nabble.com/About-Class-Type-match-td22309426.html
Short answer is that you cannot pattern match against the result of a method
invocation (foo.toString). A stable identifier must be a val (something
that is calculated and will not change for the duration of the pattern match
and be upper case or in back-ticks. So, in your case:
val doc = Foo // can't match against doc because it looks like something
you want to extract
val Doc = Foo // can match against Doc

[Lift] Re: How can i update and insert record into database via Raw sql in Lift?
Hi,
You have few options:
- DB.runQuery(UPDATE blogs set click_counts=click_counts+1 WHERE
id=1)
- DBprepareStatement(UPDATE blogs set click_counts=click_counts+1
WHERE id=?,yourDBConnection) {
stmt =
stmt.setLong(1,1)
stmt.executeUpdate()
}
Where first 1 in setLong is position in prepared statment where you
will put second value. Since You have only one ? it always will be
1.
WARNING:
runQuery is vulnerable to SQL injection in many situations (mostly
where string is passed to query)

net.liftweb.mapper.MetaMapper as def afterSave: List[(A) = Any] =
Nil.
You can add an operation to afterSave like this:
class X extends LongKeyedMapper[X] with IdPK {
def getSingleton = X
def myAfterSaveOperation(obj: X): Unit = {
println(hi!)
}
def myOtherAfterSaveOperation(obj: X): Unit = {
println(hi again!)
}
override def afterSave = myAfterSaveOperation _ ::
myOtherAfterSaveOperation _ :: Nil
/* Equal to: override def afterSave = List(myAfterSaveOperation
_, myOtherAfterSaveOperation _) */
...
}
object X extends X with LongKeyedMetaMapper[X] {
...
}
Here the underscore after myAfterSaveOperation makes it a partially
applied function.
This is similar to the way validations are added to MetaMapper
classes, as decribed in listing 6.38 in the Lift book (http://
groups.google.com/group/the-lift-book).
MetaMapper does not implement LifecycleCallbacks, that trait is indeed
used in MappedFields.

[Lift] Re: How can i update and insert record into database via Raw sql in Lift?
Hi Marcin,
Thank you very much! The update statement works now!
There is a question about the insert statement, how can i use the
prepareStatement ?
###
INSERT INTO blogs click_counts=100 WHERE id=1

I'm not familiar with it,
Thanks very much!
:)

Hi,
You have few options:
- DB.runQuery(UPDATE blogs set click_counts=click_counts+1 WHERE
id=1)
- DBprepareStatement(UPDATE blogs set click_counts=click_counts+1
WHERE id=?,yourDBConnection) {
stmt =
stmt.setLong(1,1)
stmt.executeUpdate()}
Where first 1 in setLong is position in prepared statment where you
will put second value. Since You have only one ? it always will be
1.

runQuery is vulnerable to SQL injection in many situations (mostly

When you override this method, you *must* call super:

Re: [Lift] jsonCall for clickable links
On Thu, Dec 10, 2009 at 12:13 PM, Nolan Darilek no...@thewordnerd.infowrote:
Hello, all. I'm sure this is an incredibly silly mistake on my part, but
I've never really done AJAX until playing with Lift and am at a loss as
to what's going wrong.
I'm dusting off my old geolocation web app. My current goals are
two-fold: set an initial position based on the browser, then generate
links to update that position based on nearby points. Thus far I have
the first goal working quite nicely. A snippet registers a javascript
callback to call a Lift function, and my page is being updated
correctly. Here's what I have:
def update(in:NodeSeq):NodeSeq = Script(JsRaw(
loc.onUpdate = function(lat, lon) {
+SHtml.jsonCall(JsObj(lat - JsVar(lat), lon -
JsVar(lon)), updatePosition _)._2.toJsCmd+;
}
))
The problem arises when I try calling my updatePosition function from an
SHtml.a link, like so:
val nodeList = ul
{nodes.map(nd = li{SHtml.a(
nd.name(None, None).getOrElse(Unnamed way),
SHtml.jsonCall(
JsObj(lat - nd.latitude, lon - nd.longitude),
updatePosition _
)._2
)}/li)}
/ul
How about:
val nodes: List[xxx] = ...
val nodeList = nodes match {
case Nil = pNo nodes/p
case xs = ul{xs.map(nd = li{SHtml.a(() = updatePosition(nd), Text(
ns.name(None, None) getOrElse Unnamed)}/li)}/ul
Ultimately, this function returns a JsCmd that performs two Replaces.
First, that seems just a bit ugly to me, with the escape within an
escape and all. Is there any way of eliminating that, short of placing
the ul/ into the template? Ideally this should handle the case where
there are no nearby nodes, in which case there'd be a pNo nearby
points of interest./p instead of the enclosing ul, but I haven't
coded that yet.
Next, clicking on these links doesn't work, and I get a parent is null
error from Firebug. I'm guessing that this new call is registered in the
context of a new, blank document, and hence can't perform any of the
Replace commands that work fine when this function is used in the
context of a callback in an existing document? If so, do I need another
Shtml function to make the jsonCall occur in the current DOM?
Finally, any idea as to why the link names appear as quoted strings
(I.e. Unnamed way instead of just Unnamed way)? I'm guessing it may
have to do with the embedded escape, but I'm not entirely certain.
Thanks in advance, this is such a helpful and patient community,
especially with newbies like myself. :)

[Lift] Ajax Forms and Binding
Hi all,
I think there is a simple answer to this, but I'm a little confused. I
want to update a bound element when my Ajax form is submitted. Here's
a simple version based upon what I gleaned from the wiki and the
mailing list:
lift:Test.form
pDisplay: test:display //p
pInput1: test:input1 //p
pInput2: test:input2 //p
ptest:submit //p
/lift:Test.form
class Test {
var display =
var input1 =
var input2 =
def form(xhtml: NodeSeq): NodeSeq = {
SHtml.ajaxForm(
bind(test, xhtml,
display - display,
input1 - SHtml.text(input1, input1 = _),
input2 - SHtml.text(input2, input2 = _),
submit - SHtml.submit(Submit, () = {}) // empty method
since our hidden item will be called instead?
) ++
SHtml.hidden(() = {
display = input1 + input2
// push an update to display here?
()
})
)
}
}
Am I on the right track? How do I actually get test:display / to be
updated?
Thanks,
Peter

Re: [Lift] More AJAX issues
On Fri, Dec 11, 2009 at 8:21 AM, Nolan Darilek no...@thewordnerd.infowrote:
Hello. Sorry for being the squeaky wheel on this one, but I'm really at
a loss with no way to know if this is an issue with me, or with how I'm
doing things in Lift. I've also been at this particular problem for a
bit under a day now, and am running out of things to try and words to
google.
I think I figured out yesterday's issue--likely should have set onclick
to an anonymous function returning false to prevent the browser from
running it in a new DOM--but I've decided to chage my approach slightly.
For various reasons, I'm now trying to use a select/ with an onBlur
handler which submits the value, a JSON string, to a function via
jsonCall. Here is my entire function, still with a few rough edges as I
add in the various AJAX bits:
def updatePosition(pos:Any):JsCmd = pos match {
case p:Map[String, Double] =
GeoNode.nearestTo(p(lat), p(lon)) match {
case Some(node) =
val nodes = node.within(0.001).remove(n = n.ways.size == 1)
val nodeList = select onblur = {
JsRaw(alert(\Blur!\))
}
You're making things way too complex:
select onblur=alert('Blur!')
{
nodes.map(n =
option value={JsObj(lat - n.latitude, lon -
n.longitude)}
value={JsObj(lat - n.latitude, lon - n.longitude)}
does not do what you think it does. You can't put a JSON object in the
attribute of an HTML element.
When the item is selected, what do you want to happen?
{n.name(None, None).getOrElse(Unnamed node)}/option
)
}/select
println(nodeList)
Replace(location, node.nearestWay match {
case Some(w) = pOn {w.name.getOrElse(Unnamed way)}./p
case None = pNo nearby ways/p
})
Replace(nearby, nodeList)
case _ = Replace(location, pThar be dragons! (You don't
appear to be on any current maps./p)
}
case _ =
println(pos)
Alert(Unexpected geolocation API response from browser.)
}
No matter what I try, I can't get the alert() to trigger when I tab off
the select/. The println outputs what appears to be a sane value. I've
inspected the element in Firebug, and everything appears as I'd expect.
I've saved the entire page body with everything inserted, and everything
looks fine there too. I've even done up a simple HTML document to make
sure this behaves as I'd expect, and it does exactly what I think it
should.
So, what am I missing? Is embedded JS in a Replace call not run or
something odd like that?

Hello list,
Often in an AJAX handler I need to update something on the client side;
usually a UI control that initiated the handler. The only way I know to
handle this is to generate a DOM id in the snippet during a rendering
call (like a bind() call in a flatMap over a dataset), look for that id
in my handler, and then query up or down the DOM to find the
corresponding UI component to tweak. It'd be nice if I could access the
event source node in my handler. In a standard JS event handler, 'this'
references the source element, and in some JS libraries like prototype,
a method is added to the event object to access the source element.
Given the current implementation, what's the best way to access the
client side source of a UI event in a server-side handler? It seems like
there'd be a cleaner way than what I'm doing. Thanks!

Sorry, dropped the ball on this one. Maybe change something in MySqlDriver, perhaps primaryKeySetup? Unfortunately at that level you don't know what columns have been defined.

This seems to be because IdPK adds an id of type MappedLongIndex. Only the longIndexColumnType of MySqlDriver has UNIQUE KEY in its definition. Unique keys are great but, as I mentioned, if the column is also the primary key the index is a duplication. Maybe this is something that IdPK can disable when declaring the column? At least with MySQL primary keys are guaranteed to be unique and InnoDB tables, which Mapper uses, can have issues with long primary keys[1]. Should this be fixed? Or is the more helpful answer 'Don't use MySQL'? ;-) I would use MySQL for a production site. If IdPK isn't doing what you want, then don't use it, just declare the primary key field manually.

When i logged in successfully via /user_mgt/login link and redirect
to the /all_users link not the /index page.
In your User object (singleton):
override def loginFirst = If(
loggedIn_? _,
() = {
import net.liftweb.http.{RedirectWithState, RedirectState}
val uri = /all_users
RedirectWithState(
loginPageURL,
RedirectState( ()={loginRedirect.set(uri)})
)
}
)
Thanks for any help.
Cheers,
Neil

If you want to tar up your project (please remove the target directory) and

[Lift] re: user_id has value, but get constraint exception of it being null, using JPA and Lift 1.1
Hello, I have struggled with this for a few hours and hopefully someone can see what I am doing wrong. Basically, I insert into users, I then select the user, I then set that in my address and try to insert and get an error that the user_id cannot be null, but it has a value. I am including the two entities involved at the bottom, and the part of the test that is executed. The last line in the test is where the error is thrown.

[Lift] Re: How can i update and insert record into database via Raw sql in Lift?
It works now.
I use the same executeUpdate method, and it can insert into the db.
Thanks Marcin,
Cheers,

Hi Marcin,
Thank you very much! The update statement works now!
There is a question about the insert statement, how can i use the
prepareStatement ?

I'm not familiar with it,
Thanks very much!

Hi,
You have few options:
- DB.runQuery(UPDATE blogs set click_counts=click_counts+1 WHERE
id=1)
- DBprepareStatement(UPDATE blogs set click_counts=click_counts+1
WHERE id=?,yourDBConnection) {
stmt =
stmt.setLong(1,1)
stmt.executeUpdate()}
Where first 1 in setLong is position in prepared statment where you
will put second value. Since You have only one ? it always will be
1.
WARNING:
runQuery is vulnerable to SQL injection in many situations (mostly
where string is passed to query)

I write some code but it failed, here is :
### In the model
def updateClickCountsById(id: Long) =
DB.runQuery(UPDATE blogs set click_counts=click_counts+1 WHERE
id=1)
def insertRecord() =
DB.runQuery(INSERT INTO blogs click_counts=100 WHERE id=1)
###
This two method doesn't work, so how can i update and insert via
raw SQL in the lift with Mapper?
Thanks for any suggestion !

It would seem that this error is the main problem that has to be solved: Caused by: java.net.ConnectException: Connection refused at java.net.PlainSocketImpl. socketConnect(Native Method) This should have nothing to do with the web framework, as it seems that the driver just can't connect to the database. -- You received this message because you are subscribed to the Google Groups Lift group.
