So I assume XMPP and AMQP would be other sinks / sources? If so the mind is boggling with old ideas laid to rest for some time... A thought that comes to mind is that of a source and sink are of the same type, eg. AMQP, would the interconnection make use of that technologies underlying implementation. eg. AMQP exchanges? Time to check out the progress in git...

I have something similar to the following

class VehicleType extends LongKeyedMapper[VehicleType] with IdPK {
object brand extends MappedLongForeignKey(this, Brand)

class Brand extends LongKeyedMapper[Brand] with IdPK {

When displaying the list of vehicles I need to show both the vehicle,
the vehicleType the brand in the same table
So to get the list of vehicles and caching the vehicletypes I do this:
override def findForListParams: List[QueryParam[Vehicle]] =
List(By(account, User.currentUser.open_!.account.is),
PreCache(vehicleType))
But I still get the n+1 selects when trying to resolve
vehicleType.brand. Can this be remedied somehow?

[Lift] managing foreign key object relationships with mapper
What I want to do: Create a one-to-zero-or-one relationship between User and Address. I.e. User belongs to Address. When a new user signs up for an account they need to fill in an address form at that same time. So the user.address object needs to be initialised properly when the user object is created. (this part is working ok). I also want (for backwards compatibility) existing users to get a new Address object when they update their profile if they currently don't have an address. I.e. in the users table the address foreign key is null. (this part nearly works) What the problem is: When a new user signs up it seems to work fine. The address is saved in the database and the foreign key is set on the user. However, when there is an existing user with no address (the user.address FK is NULL), they fill in the form and click update. The address is saved into the database, BUT the user.address FK is not set in the users table. It remains NULL. I have tried various combinations of things such as primeObj(), apply () and LongMappedForeignMapper, but I don't understand why the FK is not being updated. Here is my User.scala http://gist.github.com/169639 and my Address.scala http://gist.github.com/169638 I also have a hello-lift app that demonstrates this problem if it's useful.

[Lift] Re: managing foreign key object relationships with mapper
How recently did you try LongMappedForeignMapper? It's been updated recently. In any case, if you attach the test project I will try to look at it, but it may help to clarify: what is the sequence of events of saving user / saving address / setting value of user.address? The problem is that the address doesn't have its id until it's saved, which means there's nothing for user.address to reference. That is why I wrote LongMappedForeignMapper and recently added a beforeSave lifecycle event, so you just call its apply -- user.address(address) -- and it will update its Long value before its saved. - georgegeo...@mattandgeorge.com wrote: What I want to do: Create a one-to-zero-or-one relationship between User and Address.

[Lift] Proposed internal changes on Mapper?
I'm trying to fix Mapper support for Oracle and I've run into an issue. Oracle's JDBC drivers support returning autoGenerated keys, but not the way that Lift expects. The way that Lift currently works, it just calls executeUpdate with Statement.RETURN_GENERATED_KEYS set. In Oracle, this will simply return the ROWID of the inserted row, which means that we would have to do a second select to get the actual value. Alternatively, Oracle does support fetching the inserted value from a column if you use the executeUpdate(String, Array[String]) method (the Array is a set of column names to fetch). What I'm getting at is that support for autogenerated keys is very driver-specific right now, but the DriverTypes class essentially is just using some flags to control behavior in MetaMapper. I'm wondering if it would make more sense to move the support for insert queries into DriverTypes so that we have things tied directly to the drivers instead of splitting it up between two files. I'm thinking of adding something like: def performUpdate(conn : Connection, stmt : String, primaryKeyColumn : String) def performUpdate(conn : Connection, stmt : PreparedStatement, primaryKeyColumn : String) to DriverTypes, which would then allow us to define driver-specific key fetching in place. I could move the base functionality into DriverTypes itself, and then we could override as needed on specific vendor classes. The current situation with flags for brokenAutogeneratedKeys_? and wickedBrokenAutogeneratedKeys_?, while amusingly named, feels untenable in the long term as we continue to find corner cases for vendor drivers. I could add a notQuiteBrokenButDifferentAutogeneratedKeys_? flag for Oracle, but that doesn't feel right. Thoughts?

From the thread last week on ExtJS I see a discussion on loading
files

following to Boot.scala:
ResourceServer.allow {

I already have a css file being served from a directory in the
exact
same location without any additions to Boot.scala. Nonetheless, I
tried the following:
ResourceServer.allow {
case js :: _ = true

Unfortunately, this had no effect. So, how can I get my symlinked
javascript to be server? Or should I just give up on symlinks
altogether (I'm not a git master, so perhaps that was the wrong
approach anyway).

No it is not easier. The fundamental problem in distributing lift sessions is the bound functions. Sure, functions are serializable but their references may not be. For instance one can bind an ajax anonymous function and that functions can have a bunch of other references inside potentially other lambdas etc. Viktor was doing in the past some research to integrate with Terracotta but there were some issues. So consistently distributing Lift sessions in a clustered environment is a challenge but of course good ideas are more then welcome. - Ryan Donahuedonahu...@gmail.com wrote: Is anybody using Stax for anything more than prototyping or examples?

[Lift] Re: managing foreign key object relationships with mapper
I have managed to narrow the problem down some more. It seems that when the User object is saved there is a check to see whether it is clean_? This check does not seem to include a check to see if the Address object is also clean_? To get around this I tried to provide an override implementation of the dirty_? and clean_? methods on my User singleton. override def clean_?(toCheck: User): Boolean = Address.clean_?(toCheck.getAddress) super.clean_?(toCheck) override def dirty_?(toCheck: User): Boolean = Address.dirty_?(toCheck.getAddress) super.dirty_?(toCheck) However, there seems to be something wrong with the way I have done this because it is preventing the User from being saved. When I remove both the above overrides, I get the desired functionality, EXCEPT that when an address field is changed, that change is not saved because the User object is still clean_?. So the question becomes how do I let Mapper know that when the nested address object is dirty then the user object is also dirty? Or, put another way, how can I force an object to save when it is clean? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

Its a useful thing to want to implement in your custom record backends

[Lift] Re: Proposed internal changes on Mapper?
On Tue, Aug 18, 2009 at 7:12 AM, Derek Chen-Becker dchenbec...@gmail.comwrote: I'm trying to fix Mapper support for Oracle and I've run into an issue. Oracle's JDBC drivers support returning autoGenerated keys, but not the way that Lift expects. The way that Lift currently works, it just calls executeUpdate with Statement.RETURN_GENERATED_KEYS set. In Oracle, this will simply return the ROWID of the inserted row, which means that we would have to do a second select to get the actual value. Alternatively, Oracle does support fetching the inserted value from a column if you use the executeUpdate(String, Array[String]) method (the Array is a set of column names to fetch). What I'm getting at is that support for autogenerated keys is very driver-specific right now, but the DriverTypes class essentially is just using some flags to control behavior in MetaMapper. I'm wondering if it would make more sense to move the support for insert queries into DriverTypes so that we have things tied directly to the drivers instead of splitting it up between two files. I'm thinking of adding something like: def performUpdate(conn : Connection, stmt : String, primaryKeyColumn : String) def performUpdate(conn : Connection, stmt : PreparedStatement, primaryKeyColumn : String) to DriverTypes, which would then allow us to define driver-specific key fetching in place. I could move the base functionality into DriverTypes itself, and then we could override as needed on specific vendor classes. The current situation with flags for brokenAutogeneratedKeys_? and wickedBrokenAutogeneratedKeys_?, while amusingly named, feels untenable in the long term as we continue to find corner cases for vendor drivers. I could add a notQuiteBrokenButDifferentAutogeneratedKeys_? flag for Oracle, but that doesn't feel right. Thoughts? I think it's a good idea. It will also help with Record support for JDBC.

question. Unfortunately, when I try to request the file at
http://localhost:9090/js/jquery.sparkline.js, I get a 403 response
that says the page is not defined in my sitemap. There was no note
of
the request in the stdout.
Thinking that the js subdirectory is the problem, I then tried
making
the symlink in the webroot directory and got a 404 error. On stdout
it
said:

From this I gather than Lift is troubled by the presence of a
symlink
and refused to acknowledge its presence. Is this true? If so, why?
From the thread last week on ExtJS I see a discussion on loading
files
in webroot, including supporting a css directory by adding the
following to Boot.scala:
ResourceServer.allow {
case css :: _ = true
}
I already have a css file being served from a directory in the
exact
same location without any additions to Boot.scala. Nonetheless, I
tried the following:
ResourceServer.allow {
case js :: _ = true
}
Unfortunately, this had no effect. So, how can I get my symlinked
javascript to be server? Or should I just give up on symlinks
altogether (I'm not a git master, so perhaps that was the wrong
approach anyway).

You can control this via the newly added LiftRules:
/**

var formatDate: Date = String = date = date match {case null =
LiftRules.formatDate(new Date(0L)) case s = toInternetDate(s)}

something that's user-specific

var parseDate: String = Box[Date] = str = str match {
case null = Empty
case s = Helpers.toDate(s)
}
So, you can put in functions that parse and format dates based on the
currently logged in user, etc.

[Lift] Re: how to construct a table with a set number of columns
You mean a word wrap / FlowLayout type of arrangement?
One idea is to have two snippets like yours, one for tr's and one for td's; and
make you class a StatefulSnippet and initialize a 2D array there (or the
RequestVar equivalent); and prepare the row for the td snippet in the tr
snippet.
Another option is to use NodeSeq functions (FuncBindParam) inside one snippet
instead of multiple snippets. So in your snippet arrange a 2D array, then bind
say foreach:row to a function that iterates (flatMap) over the rows, binding
foreach:col to each column of the current row (flatMap) with a NodeSeq function
that does the bind of the cell contents.

[Lift] Re: how to construct a table with a set number of columns
With the second option you might be able to do a foldLeft instead of a flatMap
to List.take(10) one row at a time.

add a new parameter which is the ajax invocation function. In other

[Lift] Re: slow down ajax?
Having
def ajaxText(value: String, jsFunc: Call, func: String = JsCmd)
jsFunc parameter is a Call which is defined as:
case class Call(function: String, params: JsExp*) extends JsExp
So by this you represent a javascript function invocations.
So assuming somewhere you have a javascript function like:
function myFunc(myParam, callback) {
// do some logic
callback()
}
in the snippet we have something like:
ajaxText(task.dueOn.toString,
Call(myFunc, Str(some_param_value))
v = { task.dueOn(v.toLong).save; reDrawTasks();})
As you can see we called Call(myFunc, Str
(some_param_value)) .. .we provided the JS function name and one
parameter. Lift will add the second parameter which is the callback
function. This callback function represents the actual ajax call and
since it is a callback you can invoke it whenever you want inside
'myFunc' javascript function. In other words you can defer the actual
ajax call as you see fit.
Now myFunc function declaration can be:
1. In your own .js file
2. Written in the script tag inside your html
3. Generate using Lifts' JS absctrations using JsCmds.Function()
object such as:
JsCmds.Function(MyFunc, List(myParam, callback),
a_JsCmd_expression_which_is_the_function_body)
The main point in all this is that you can defer the actual ajax call.
You know better if this fits your case.

[Lift] Re: how to construct a table with a set number of columns
You could do something like this.
Snippet:
def func(xhtml: NodeSeq): NodeSeq = {
val foos = Foo.findAll(...)
val rowSize = (S.attr(rowSize) openOr 10).toInt
val rowNum = (foos.size + rowSize - 1) / rowSize
List.range(0, rowNum).foldLeft(Util.emptyNodeSeq)((ns, i) = {
val start = i*rowSize
val end = start+rowSize
ns ++ bind(list, xhtml, row - row(foos.slice(start, end))
_)
})
}
private def row(foos:List[String])(xhtml: NodeSeq) : NodeSeq =
foos.foldLeft(Util.emptyNodeSeq)((ns, foo) = ns ++ bind(foo,
xhtml, name - foo.name))
Then your template can use table/tr/td or it could just use floating
divs that wrap over when necessary:
table
lift:MyPage.func rowSize=10
tr
list:row
tdfoo:name//td
/list:row
/tr
/lift:MyPage.func
/table
OR
lift:MyPage.func
list:row
div class=cellfoo:name//div
/list:row
/lift:MyPage.func
For an empty NodeSeq that works in the foldLeft I've had to create the
following. Anybody know a better way?
object Util {
val emptyNodeSeq : NodeSeq = NodeSeq.fromSeq(Seq(xml:group/
xml:group))
}

It's for an organization that will have around 5 people using it total, not necessarily at the same time. So I don't need any fancy setup like continuous integration etc. It's also the second version of the first webapp I've written (the first was in PHP). After I sent the question, I came across a thread from David (it was on Nabbles, I would guess from this group) where he described how to use nginx as the frontend web server and Jetty as the backend. I like Nginx as a front end because you have serve multiple virtual domains from the same front end server (this is handy for static sites run on the same server). Further, Nginx runs as root in order to listen to port 80 and that means you don't have to have some iptables port forwarding to your Jetty instance and you don't have to run Jetty as root. I should probably ask this on that thread, but [when] would I want to use nginx and not just Jetty? (Nothing else needs to be running on the server.) Also, what's the difference between the Jetty download link it had ( www.tunaforcats.com/deploy_jetty.tgz) and something you can download from Jetty's site? (And what exactly *is* tunaforcats.com ??!) Question 2: Any reason to run H2 either as a separate process or as part of the webapp? Part of the web app... it starts up and shuts down with the app. Thanks.

[Lift] Re: CMS for Lift?
I would like to know how the Lift/Scala can leveraged to with Alfresco or any other open source Java based CMS. Terry J. Leach On Aug 17, 2:09 pm, Stefan Scott stefanscottal...@gmail.com wrote: I'll chime in here since I've been evaluating several CMSs lately. I previously used Drupal and WordPress as my CMSs - now however I'm moving everything to MODx because of the increased flexibility and more-logical organization, and I'm also impressed with the demos of SilverStripe, TypoLight Typo3 - and LifeRay, which is written in Java instead of PHP. (LifeRay seems to be much more than a CMS - it claims to offer collaboration and social networking.) Some on-line demos here: MODx -http://trymodx.com/ SilverStripe -http://demo.silverstripe.com/ TypoLight -http://www.typolight.org/demo.html Typo3 -http://testsite.punkt.de/ LifeRay -http://demo.liferay.net/web/guest/home It would be good to take a look at these additional CMSs as they offer some capabilities beyond WordPress and Drupal. Drupal in particular is wildly popular but it may no longer be the best candidate to imitate, as it is less well-organized and less flexible/customizable (compared say to MODx, which lets you take CSS from an existing site and use it for your site, and which lets you apply a template to a single document, unlike Drupal where a theme applies to the entire site). To keep up with advanced CMSs, Drupal has evolved to use a bunch of (often redundant or competing) modules which are not always compatible with current releases. Examples of things that Drupal treats as add-ons (modules) are: custom content (the CCK/Views modules, with their confusing albeit AJAX-y interface), multi-language, and photo galleries (I gave up on Drupal after a few days of trying out various photo gallery modules, none of which I could understand). Finally, it seems odd that Drupal, as a content management system, lacks something all advanced CMSs have: a *treeview* of the overall site content. Instead, it only has a jumbled *list* of content, sorted by not by location but by last edited (!), with all translations also scattered through the list based on last- edited date, and this list is buried several levels deep in the admin navigation system, unlike the site content treeview navigator which is prominently displayed (usually on the left) in advanced CMSs. (Of course, I don't want to veer off-topic here and start a CMS flame war here in this liftweb discussion. :-) Regarding dynamic site map creation - I do know that MODx has something like this, using WayFinder to create a menu from selected branches of the site's document tree, automatically including any updated sub-branches, and I believe most other advanced CMSs have something like this too. LifeRay seems very intriguing - it claims to do a lot beyond just CMS. Since it's written in Java (not PHP), who knows if some of its code could be leveraged in Scala. So these might be some additional interesting CMSs to keep in mind (beyond Drupal and WordPress) when building a new CMS using liftweb. - Stefan Scott On Aug 16, 3:13 pm, glenn gl...@exmbly.com wrote: Philip, I'm working on a cms system in Lift.

[Lift] PreCache's use of WHERE ... IN
Given something like Tip.findAll(By(Tip.venueid, ), PreCache (Tip.userid)) The PreCache query param appears to do it's preaching by generating a query that uses IN, like so: SELECT DISTINCT users.id, users.firstname, users.lastname FROM users WHERE id IN (SELECT userid FROM tips WHERE venueid = ); This is a bit concerting as I have found queries of this form to be far less efficient (on a stock MySQL instance at least) than something like this (which will return the same results): SELECT DISTINCT users.id, users.firstname, users.lastname FROM users, tips WHERE tips.userid = users.id AND tips.venueid = ; Is there any particular reason that Lift is generating WHERE ... IN queries? Is there some way to instruct Lift to do otherwise? If not, should this possibly be changed? This is somewhat related to my last post on this thread as it also relates to WHERE ...

Oracle's JDBC drivers support returning autoGenerated keys, but not the way that Lift expects. The way that Lift currently works, it just calls executeUpdate with Statement.RETURN_GENERATED_KEYS set. In Oracle, this will simply return the ROWID of the inserted row, which means that we would have to do a second select to get the actual value. Alternatively, Oracle does support fetching the inserted value from a column if you use the executeUpdate(String, Array[String]) method (the Array is a set of column names to fetch). What I'm getting at is that support for autogenerated keys is very driver-specific right now, but the DriverTypes class essentially is just using some flags to control behavior in MetaMapper. I'm wondering if it would make more sense to move the support for insert queries into DriverTypes so that we have things tied directly to the drivers instead of splitting it up between two files. I'm thinking of adding something like: def performUpdate(conn : Connection, stmt : String, primaryKeyColumn : String) def performUpdate(conn : Connection, stmt : PreparedStatement, primaryKeyColumn : String) to DriverTypes, which would then allow us to define driver-specific key fetching in place. I could move the base functionality into DriverTypes itself, and then we could override as needed on specific vendor classes. The current situation with flags for brokenAutogeneratedKeys_? and wickedBrokenAutogeneratedKeys_?, while amusingly named, feels untenable in the long term as we continue to find corner cases for vendor drivers. I could add a notQuiteBrokenButDifferentAutogeneratedKeys_? flag for Oracle, but that doesn't feel right. Thoughts? I think it's a good idea. It will also help with Record support for JDBC.

[Lift] Re: CMS for Lift?
I've been scratching my head about that one too. I have used both Alfresco and opencms to produce both dynamic and static and in the case of dynamic they have their own servlet/filter to render the content - I've not yet spent enough time working out how and if they can be fitted together. For me, having used Hybris (J2EE ecommerce engine with some CMS built in), I'd like to be able to have page fragments in a template served from the CMS (lift snippets presumably) that would be created/ maintained with some aspect of workflow by CMS user(s) in an associated CMS lift webapp with funky (X)HTML editor support. My web guys, non-lift devs, can then sprinkle cms tags where appropriate.

[Lift] Sitemap and mapper dependency's effects on object reuse
I'm looking for some answers on best coding practices, particularly when it comes to object reuse. In a data-centric application, where the Sitemap is used to navigate through your mapper entities, has anyone given much thought to the object dependencies this can create. In the case of page specific rendering with SiteMap, for example, where should the Menu entries go - in their own object, or should they stay with the MetaMappers. And what about the templates, which can have dependencies on snippets, which reside elsewhere. In other words, it seems to me that good design requires managing the chain of dependencies that an ordinary Menu entry may require. A consistent approach is always best, and I admit that I don't have one at present. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

Having
def ajaxText(value: String, jsFunc: Call, func: String = JsCmd)
jsFunc parameter is a Call which is defined as:
case class Call(function: String, params: JsExp*) extends JsExp
So by this you represent a javascript function invocations.
So assuming somewhere you have a javascript function like:
function myFunc(myParam, callback) {
// do some logic
callback()
}
in the snippet we have something like:
ajaxText(task.dueOn.toString,
Call(myFunc, Str(some_param_value))
v = { task.dueOn(v.toLong).save; reDrawTasks();})
As you can see we called Call(myFunc, Str
(some_param_value)) .. .we provided the JS function name and one
parameter. Lift will add the second parameter which is the callback
function. This callback function represents the actual ajax call and
since it is a callback you can invoke it whenever you want inside
'myFunc' javascript function. In other words you can defer the actual
ajax call as you see fit.
Now myFunc function declaration can be:
1. In your own .js file
2. Written in the script tag inside your html
3. Generate using Lifts' JS absctrations using JsCmds.Function()
object such as:
JsCmds.Function(MyFunc, List(myParam, callback),
a_JsCmd_expression_which_is_the_function_body)
The main point in all this is that you can defer the actual ajax call.
You know better if this fits your case.

See the jsFunc parameter. Essentially you are specifying your function
call that may have one parameter. To your parameter list List we'll
add a new parameter which is the ajax invocation function. In other
words your code gets that function that does the ajax call meaning
that you have the control over when the ajax call is made.
