[Lift] Re: lift-json's extract and Mapper
Hi Peter,
To select multiple packets you need to first select the objects within
the array. Like this:
for {
JObject(packet) - parse(s)
JField(node, JString(node)) - packet
JField(dt, JInt(dt)) - packet
JField(temp, JDouble(temp)) - packet
} yield // construct Packet here
Cheers Joni

I've been playing with just that for comprehension syntax over the

{

I've had some problems iterating across the parsed results. If I do:
for {
json - parse(s)
JField(node, JString(node)) - json
JField(dt, JInt(dt)) - json
JField(temp, JDouble(temp)) - json
} yield // construct Packet here
I will end up with 8 Packets. Should I be doing something like JArray
(json) - parse(s)?
Thanks for your help,

This certainly sounds like a reasonable feature request, I will take a

Meanwhile, you can use tmp case class as Kevin noted, or use for-
comprehension to query the json. Something like:
{
packet: {
node: 00:1D:C9:00:04:9F,
dt: 1254553581405,
temp: 27.5
}
}
val json = parse(s)
for {
JField(node, JString(node)) - json
JField(dt, JInt(dt)) - json
JField(temp, JDouble(temp)) - json
} yield // construct Packet here
That's a bit verbose but quite flexible. This test case contains more
query

[Lift] Re: How do you deploy yours?
Indrajit, Your right, jetty-runner is Jetty 7. The only tie we have to Jetty 6 would be this line: val cc = Class.forName (org.mortbay.util.ajax.ContinuationSupport) It would be trivial to add a match or whatever that determined the correct type to use... The question is, why haven't we done this already? I suspect its just a time / capacity issue but wanted to check. I know I could write a jetty 6 wrapper, but that is my fallback position as something more OOTB would be preferable.

[Lift] Re: Concurrency control of database access in Lift/Comet
Thanks Kevin, I know, that this is more of a theoretical problem, but now that I have read so much about Actors and concurrent programming, I am actually curious about the underlying concurrency strategies taken by Scala. Infact I realize, that this is actually more a Scala question, than a Lift one. But it is interesting for lift too, as it it builds upon Scalas actor model. So as far as I understand you suggest, that I take the concurrency problem over to the database and leave it up to the database to handle concurrency like in the following flow schema: Many open Comet connections - one thread per one or more client socket connections - one database connection per thread - concurrency handling in DB This approach however means that my application will generate many open connections to the database and therefore much connection (IPC-) overhead. Also by doing so it doesn't actually use the advantages of Scalas concurrency model. My approach was instead something like this: Many open Comet connections - one thread per one or more client socket connections - one thread receiving messages from all other threads putting them in a message queue - one database connection - DB access Concurrency in such model is handled by the message system of Scala, which AFAIK is thread safe and doesn't use locks?! The advantage would be, that I just would need one database connection, which to me sounds more efficient. I think my question can be drilled down to the following. How efficient is Scala's concurrency model? Do Scala Actors use locks in the underpinning or are concurrency operations atomic? (I read here http://www.ibm.com/developerworks/java/library/j-scala04109.html that Scala uses locks under the hood too so after all I could finish up with the same problems like with shared memory and mutexes?)

So definitely yes, event driven programming is quite fitful in Lift.

[Lift] Re: Concurrency control of database access in Lift/Comet
Its really more of a Java problem, or JDBC to be specific. The normal way to configure this would be to establish a pool of connections, when a thread, or actor, needs to interact with the database it takes a connection from the pool, uses it, then returns it to the pool. This is the same regardless of how you approach concurrency (actors/locks/dataflow/etc.). When every connection in the pool is in use, subsequent requests will block until one becomes available, thus limiting the number of simultaneous requests to the DB. Tuning is then handled by adjusting the pool size to a value that delivers greatest throughput from the database. Depending on your exact requirements, it's then possible to build a layer on to of this that can take advantage of asynchronous messages to actors On Mon, Oct 5, 2009 at 12:50 PM, donfranciscodequevedo donfranciscodequev...@gmail.com wrote: Thanks Kevin, I know, that this is more of a theoretical problem, but now that I have read so much about Actors and concurrent programming, I am actually curious about the underlying concurrency strategies taken by Scala.

Loving the new lift-json code. We've been producing XML for a REST
API, and now need to produce JSON. lift-json to the rescue,
except...the Xml converter doesn't handle attributes:
scala val xml = user id=7nameBert/name/user
xml: scala.xml.Elem = user id=7nameBert/name/user
scala val json = toJson(xml)
json: net.liftweb.json.JsonAST.JValue =
JObject(List(JField(user,JObject(List(JField(name,JString(Bert)))
scala JsonDSL.compact(JsonAST.render(json))
res5: String = {user:{name:Bert}}
I'd expect res5 to be something like: {user:{id:7,name:Bert}}
I'm either missing a clue, or this is a feature request.
I can see there's ambiguity in how you might map the above JSON back
to XML with attributes, but it seems reasonable that if you have XML +
attributes they would be present in a JSON representation.

[Lift] Re: Concurrency control of database access in Lift/Comet
Howdy, I think you misunderstand how Actors work. An Actor only consumes resources while it is processing an item in its mailbox. So if an Actor is hanging out, doing nothing, it will only consume memory (like any other object.) When the Actor receives a message, it allocates some additional resources to process the message. Those resources always include a thread. In Lift, those resources also include an S scope. When S (session state) comes into scope, a connection to the RDBMS may be allocated (depending on you application's transaction policy) so that all RDBMS interactions that take place during that message processing will be part of a single RDBMS transaction. There are no resources allocated while a browser is waiting for a Comet event (except an NIO connection and a few objects allocated in memory). It's only when something happens that will cause HTML to go to the browser that events get put into mailboxes and RDBMS connections get pulled out of a pool. I hope this helps clear up the questions you had.

[Lift] Re: ShutDown and CometActor
When you send the shutdown message, oddly enough, the CometActor shuts down. You don't have to do this (in fact, don't do it). Lift will shut the CometActor down automatically.

Yes, just took a look at jetty-runner. Feature wise, it's blows away the older mechanism man! Any thoughts in and around altering the lift code to adjust the package based on jetty version? I can think of two options basically: 1. Move to jetty 7 and be done with it. 2. Allowing user option (via -Djetty.version) during archetype:generate. jetty.version can be an overridable archetype property that defaults to (say 6) but user can do -Djetty.version=7. Depending on the jetty version, the *.scala, *.xml etc. can be filtered to make the right kind of adjustment during archetype creation.

The only tie we have to Jetty 6 would be this line: val cc = Class.forName (org.mortbay.util.ajax.ContinuationSupport) It would be trivial to add a match or whatever that determined the correct type to use... The question is, why haven't we done this already? I suspect its just a time / capacity issue but wanted to check. I know I could write a jetty 6 wrapper, but that is my fallback position as something more OOTB would be preferable.

In fact, Zimbra Desktop does this too. Pure Prism+Jetty bundled as 'desktop application'. That you can have 'double-click' friendly application helps :-) Few notes: 1. Embedding Jetty server is super easy with org.mortbay.jetty.Server. Something that we have in Lift - well almost ;-) The RunWebApp in the archetypes are primitive use case of such. [1] 2. Jetty Runner is available only on Jetty 7.x series I think (not certain). But yes, looks good either way. 3. Jetty has this clean and nice way of having web-app specific jetty config tucked inside the application (war or expanded) within WEB-INF/jetty-web.xml which is basically an XmlConfiguration instance applied on the specific WebApplicationContext instead of the Container Context. [2] 4. An archetype that does self deploying is something that I have on my todo-list. Do you think this would make sense? 5. Maven assembly plugin would do.

Hi Gregor,
For my Mapper model called Packet, my companion object looks like
this:
object Packet extends Packet with LongKeyedMetaMapper[Packet] {
override def dbTableName = packets // define the DB table name
/* register callback to send the new packet */
override def afterCreate = createdRow _ :: super.afterCreate
private def createdRow(packet: Packet) {
DatacenterBroker.createdPacket(packet)
}
}
As you can see, after a Packet is created it is sent to an Actor
(using the broker object as an intermediary). The Scaladocs for
MetaMapper show many before and after events that you can override
like I've done with
afterCreate:http://scala-tools.org/mvnsites-snapshots/liftweb/lift-mapper/scalado...

Hi Marius,
Thanks for your fast response. As an app developer, if I would like to
get notified from the persistence layer, that some changes to my
domain model have happened, how could I get such functionality with a
Scala actor? By subclassing the persistence class? Or is such
functionality already integrated in the persistence layer?
Let's say I would like to get notified before some data is inserted in
the database. How would I achieve that?
Thanks again

Scala has a natural support for events notifications = Scala Actors.
It's a very natural fit for building event driven systems. In Lift
we're moving CometActors to LiftActors instead of Scala Actors due to
some memory consumption problems with current Scala actors
implementation which are probably fixed now in Scala 2.7.7 RC1.
So definitely yes, event driven programming is quite fitful in Lift.

I have been looking for Web frameworks that will take advantage of an
Event Driven programming model.
Some Frameworks like Python's Zope and Grails manage to subscribe to
Model Events. E.g. one can subscribe to a notification message,
whenever a domain model gets changed, added, deleted, etc. (like
explained here http://bit.ly/2AkVBy)
Can the Lift Framework throw such events too? Similar to the way
Grails and Zope do it?
Or is there another way in Lift to do the same?
I must say that I preety much do like the Lift Framework and it's
fresh approach on important tasks like Comet, Templating, Active
Record, Web Services, Localization...
However one of my key requirements would be simple handling of events
and notifications.
Thank you

That's going to be even worse. You'll kill something out from under Lift...
it's going to cause a huge pile of pain.
You can remove an Actor from the session and that will cause ShutDown to be
sent to it, but depending on how the Actor was written it's not going to
stop processing its mailbox.
Bottom line... there's no way to tell if a user is not looking at a page
with an Actor anymore. The best way to deal with that is timing the Actor
out. It's going to take time (your timeout period), but it's the best way
to do it.

[Lift] Re: lift nearly inaccessible for newby
Being a non-programmer, and additionally not having a Java background, which framework are you comparing Lift to when you say it's not easy? :) Can you clarify: Is this going to be a site, or a back end to a mobile app that sits on the phone? On Mon, Oct 5, 2009 at 2:32 PM, koveen liep...@xs4all.nl wrote: Hi, Being a no-programmer and having no Java-background I'd like to have mentioned that Lift really isn't an easy framework. Having said that, I will try to read my way into this system and try to solve the problems I encounter. I have one question. I would like to establish a login method where a visitor of my site (to be) could be accepted as a valid user, based on the info the server receives when the visitor enters the site. In my case it will be a site for mobile phones and some mobile phone operators will provide me with the telephone-number of the user once she enters. Once a user has paid for the service, this number alone should be enough to make the visitior into a valid user. Without needing to log in. I have read the following on: http://demo.liftweb.net/ws t's easy to dispatch incoming HTTP requests. In your Boot class create a PartialFunction that matches a pattern related to the incoming request and then create a short-lived controller to service the request. This code matches all the requests to /webservices/ and assigns the stuff in '' to the variable c. Then the code attempts to find a public method with that name on the controller. If the method exists, it's invoked and Lift processes the result. I assume I will have to write my own public method and place it where??? in the direcory webservices.? Maven didn't include such a directory in my project set-up, so I assume this webservices are on an external server and that I will have torefer to and extend an existing function. Am I correct in this? and is there an exemple of how to write such a method. I would be really happy to make some progress, and any help is welcome.

Because when the users searches on a new keyword, the actors that were

[Lift] Re: MappedStringForeignKey and Schemifier
I know there are a lot of mapper tickets open, but please add this one.
I'll spend a day or two this week getting the Mapper tickets closed.

I have a model, Node, with a string index. I have another model,
Packet, which has a MappedStringForeignKey to Node. Unfortunately,
Schemifier doesn't seem to respect the MappedStringForeignKey type and
creates a BIGINT column in the packets table, as you can see from its
output:
INFO - CREATE TABLE packets (temp DOUBLE , id BIGINT UNSIGNED NOT NULL
AUTO_INCREMENT UNIQUE KEY , mac BIGINT UNSIGNED , dt DATETIME , mah
DOUBLE , lux DOUBLE , rssi DOUBLE) ENGINE = InnoDB
INFO - ALTER TABLE packets ADD CONSTRAINT packets_PK PRIMARY KEY(id)
INFO - CREATE INDEX packets_mac ON packets ( mac )
Is this a bug? I can override fieldCreatorString for the foreign key
but I don't think I should have to. This is with 1.1-SNAPSHOT.

And the relevant parts of my models:
class Node extends KeyedMapper[String, Node] {

/* MAC address as primary key */
def primaryKeyField = mac
object mac extends MappedStringIndex(this, 17) with IndexedField

I have no idea what you application logic looks like, so I don't know what
call your exit will do. If you call exit on a CometActor, you'll mess
things up (as you've discovered.) But your search shouldn't be taking place
in the CometActor. Your search should be taking place on other

has nothing to do with the CometActor lifecycle. It is all your application
level stuff.

In my app, when the user is done searching on one keyword, they click a

Why? Actors do not consume threads, they consume memory unless they are
actively processing a message.

Interesting. I will try that. And I won't send any more
ShutDownMessages :)
Though I should add that each CometActor is doing a lot of
processing. So I it would be good if I could shut one down somehow when
the
user searches on a new term. Timeout won't work because there is no way
to
know how long it will take.
Maybe I could just kill all the actors directly that are doing the
processing.
That's going to be even worse. You'll kill something out from under
Lift... it's going to cause a huge pile of pain.
You can remove an Actor from the session and that will cause ShutDown
to be sent to it, but depending on how the Actor was written it's not
going
to stop processing its mailbox.
Bottom line... there's no way to tell if a user is not looking at a
page with an Actor anymore. The best way to deal with that is timing the
Actor out. It's going to take time (your timeout period), but it's the
best
way to do it.

Understood. My intention is to send a ShutDown message to the
CometActor when somebody closes the browser. I need this so that when
they
visit the page in a browser again, the CometActor is 'reset'.
First, there's no way to determine if the browser window is closed.
Second, *DO NOT* send a ShutDown message to the CometActor. This is
an internal Lift piece of housekeeping. If you do this, you will break
stuff. Don't do it. (There is a reason the message is not private,
but it
should not be used for this purpose.)
CometActors can be named:
lift:comet type=Search name={searchString}/
You can then have a separate CometActor for each searchString.
Voila... you get what you want. Now, how do you make then CometActor
go
away when it's not being used anymore?
In your CometActor:
override def lifespan: Box[TimeSpan] = Full(3 minutes)
That means if a CometActor does not appear on a page for 3 minutes,
it's removed from the session. If the named CometActor is requested
again,
a new one will be created.

[Lift] Re: redirectTo throwing net.liftweb.http.ResponseShortcutException: Shortcut
I'm not familiar with JsCmds etc., but you are calling
registerThisSnippet in the code that gets invoked by the ajax button.
What needs to happen somehow, if it's possible, is that after it
redirects, triggering a new request, you have to call
registerThisSnippet in that request.
As you pointed out that's possible with
StatefulSnippet.redirect/S.redirectWithState.
Looking at the source code for JsCmds.RedirectTo, the problem is as
follows: It's not a server side redirect; it's sending a
window.location=... javascript statement to be executed. If you
can't get it to use a server side redirect, what you may have to do is
register a function and modify the URL passed to JsCmds.RedirectTo to
include its name. I noticed there's a method S.mapFuncToURI--does that
do what you need?

I believe that this JsCmds.RedirectTo() is not setting the function

So when I use JsCmds.RedirectToI'm not getting the same
StatefulSnippet instance. Is there a way to redirect that will
preserve my StatefulSnippet instance?
url/a(StatefulSnippet)
- links to url/b(StatefulSnippet) using super.link()
url/b - redirects back to url/a
url/a is a grid, with a starting 'page' number, and url/b is a edit
form. When the user is done with url/b they click 'save' which sends
them back to url/a, hopefully at the same place in the grid. When
returning to the grid from the edit page, the grid is reloading from
the beginning. I need a way to preserve the original StatefulSnippet

This is a feature request and I just committed an implementation to my

how they are mapped:

I'd expect res5 to be something like: {user:{id:7,name:Bert}}
I'm either missing a clue, or this is a feature request.
I can see there's ambiguity in how you might map the above JSON back
to XML with attributes, but it seems reasonable that if you have XML +
attributes they would be present in a JSON representation.

[Lift] Re: redirectTo throwing net.liftweb.http.ResponseShortcutException: Shortcut
Try:

I'm not sure this is the right way to do it, but I think that should

I believe that this JsCmds.RedirectTo() is not setting the function

Thank you for such a quick response. I only had to make one change,
as posted I got:
found : Unit
required: net.liftweb.http.S.AFuncHolder
S.fmapFunc(registerThisSnippet)(binding =
JsCmds.RedirectTo(/workflow/index? + binding + =_))
Changed to:
S.fmapFunc(() = registerThisSnippet)(binding = JsCmds.RedirectTo(/
workflow/index? + binding + =_))
And it works like a charm.

With ubuntu you can add the Sun JDK by installing the sun-java-6-jdk

hi Naftoli, thanks for your interest. On Oct 5, 10:50 pm, Naftoli Gugenheim naftoli...@gmail.com wrote: Being a non-programmer, and additionally not having a Java background, which framework are you comparing Lift to when you say it's not easy? :) First I read a book about rails, explaining things from the start, I did watch quite a lot of nice video's on the web explaining some basic tricks with Rails. I think it is a system that is easy to start with but I became nervous about recurring issues about scaling, the integration of Rails and Merb and had the idea, maybe wrong, that it was a system too much in transition. I read part of the tutorial of Lift, installed it on my computer using Maven, but in a way I got lost. Then I partially read a book about Wicket. I like the system very much, especially one trick exited me: the Ajaxfallbacklink in which a link worked in a simple way when javasript is disabled , but at the same time has some Ajax functionality when Javascript is enabled on the users system. I liked this feature very much, but the integration with a database is not an integral part of the Wicket-system and can be acquired via a Wicket-Spring-Hibernate combination. This seemed too much for me to get into as a starter. That's how I came back to Lift. I need a stable database-connection. You need one when you hope that people will be paying some, even small, amount of money for your service. Can you clarify: Is this going to be a site, or a back end to a mobile app that sits on the phone? I just want to make a site But I hope it is clear I am not here to criticise anybody, it is just that often I feel this system is way over my head. Maybe that will change. thanks Ko On Mon, Oct 5, 2009 at 2:32 PM, koveen liep...@xs4all.nl wrote: Hi, Being a no-programmer and having no Java-background I'd like to have mentioned that Lift really isn't an easy framework. Having said that, I will try to read my way into this system and try to solve the problems I encounter. I have one question. I would like to establish a login method where a visitor of my site (to be) could be accepted as a valid user, based on the info the server receives when the visitor enters the site. In my case it will be a site for mobile phones and some mobile phone operators will provide me with the telephone-number of the user once she enters. Once a user has paid for the service, this number alone should be enough to make the visitior into a valid user. Without needing to log in. I have read the following on:http://demo.liftweb.net/ws t's easy to dispatch incoming HTTP requests. In your Boot class create a PartialFunction that matches a pattern related to the incoming request and then create a short-lived controller to service the request. This code matches all the requests to /webservices/ and assigns the stuff in '' to the variable c. Then the code attempts to find a public method with that name on the controller. If the method exists, it's invoked and Lift processes the result. I assume I will have to write my own public method and place it where??? in the direcory webservices.? Maven didn't include such a directory in my project set-up, so I assume this webservices are on an external server and that I will have torefer to and extend an existing function. Am I correct in this? and is there an exemple of how to write such a method. I would be really happy to make some progress, and any help is welcome.

I can think of two options basically: 1. Move to jetty 7 and be done with it. 2. Allowing user option (via -Djetty.version) during archetype:generate. jetty.version can be an overridable archetype property that defaults to (say 6) but user can do -Djetty.version=7. Depending on the jetty version, the *.scala, *.xml etc. can be filtered to make the right kind of adjustment during archetype creation.

The only tie we have to Jetty 6 would be this line: val cc = Class.forName (org.mortbay.util.ajax.ContinuationSupport) It would be trivial to add a match or whatever that determined the correct type to use... The question is, why haven't we done this already? I suspect its just a time / capacity issue but wanted to check. I know I could write a jetty 6 wrapper, but that is my fallback position as something more OOTB would be preferable.

In fact, Zimbra Desktop does this too. Pure Prism+Jetty bundled as 'desktop application'. That you can have 'double-click' friendly application helps :-) Few notes: 1. Embedding Jetty server is super easy with org.mortbay.jetty.Server. Something that we have in Lift - well almost ;-) The RunWebApp in the archetypes are primitive use case of such. [1] 2. Jetty Runner is available only on Jetty 7.x series I think (not certain). But yes, looks good either way. 3. Jetty has this clean and nice way of having web-app specific jetty config tucked inside the application (war or expanded) within WEB-INF/jetty-web.xml which is basically an XmlConfiguration instance applied on the specific WebApplicationContext instead of the Container Context. [2] 4. An archetype that does self deploying is something that I have on my todo-list. Do you think this would make sense? 5. Maven assembly plugin would do. I haven't tried this myself, but Maven shade plugin looks something close.

[Lift] Re: log4j
Changing the logging has to come at the very beginning of the boot method. I'm using slf4j in a 1.0.2 project and it's working fine. The very first line of my boot method is: LogBoot.loggerSetup = () = true which basically disables Lift setting up any logging (you'll have to do your own configuration via xml or API). Try that and let me know if you still have problems. Derek On Fri, Oct 2, 2009 at 3:02 PM, Christopher Mason cjma...@gmail.com wrote: So, is this support only present post 1.0.2? Cause in 1.0.2 it seems like log4j symbols are referenced before my Boot.boot() gets called (see below). Also, what do you mean by Configure slf4j to use Slf4jLogBoot (doc says Note that slf4j back-end should be configured previously to use Slf4jLogBoot. which also doesn't make sense to me).Sorry I missed the Slf4jLogBoot class; I'm still learning how to use Intellij to properly navigate scala code.

[Lift] Re: execute code when browser is closed
Let me start again. Maybe I am misunderstanding when Comet should be
used. In my application, people search for web pages. I do a lot of
processing for each resulting page. First I just display the links and
then as the processing is finished, the links on the page are
automatically modified with the data I just found for each link. This
is all working fine.
But, the session is being shared among all users so if I make one
search in one browser, and then make another search from another
browser, I get the results from the first browser.
David suggested I name each CometActor differently. That is not
working, though maybe I am not doing it right.

[Lift] Re: alternate webroot using Boot?
I found this issue and voted on it at github. I've done a few presentations on scala at my job, a java shop, and used lift in one of the demos. A few people are quite interested in scala, and one is particularly interested in lift. The project I work on is in spring mvc, and it would be really cool to deploy a lift app beside it, as I could expose the spring context and show what portions of the actual app /might/ look like in lift. On Sep 21, 7:07 pm, David Pollak feeder.of.the.be...@gmail.com wrote: On Tue, Sep 15, 2009 at 10:52 AM, tonyc tculs...@gmail.com wrote: Thanks David. It will mean developers can introduce lift gradually without a big bang approach, which is what I'm trying to do. It's quite normal to change the url-pattern on servlets/filters and it's also unusual for a filter which acts on *.html files in the root to override the default action (of serving up an html file). When dynamically changing the content of an html file before serving up, it's probably a sign that an alternative file extension and/or location is needed. JSPs (ugh!), do end in *.jsp, not *.html so that the web container knows not to serve them directly up, ie. they are picked up by the JSP Servlet, not a filter that matches on every url. Lift supports URL rewriting for inbound requests, so you could turn /something/index into /index. The challenge as I see it is that Lift also re-writes URLs on the way out and that might cause issues (the URLs would not be correctly re-written from /index to /something/index). I'll open a ticket because this also has to do with context paths and Lift is pretty rigid about context paths. Maybe there is a way with what's already there, but I'm missing something?

This is the closest thread to this subject so I thought I'd post here. I'm trying to get the LiftFilter to match on a distinct url-pattern to allow the other filters/servlets to continue matching their current url patterns. For this reason I need LiftFilter to match on say lift-test/* and so it receives requests like http://host/lift-test/index.html, but NOT like http://host/index.html I think you have to put the index.html file in /lift-test/index.html If this becomes a common occurrence, I think we can introduce something into LiftRules that will offset where things are looked up and also the re-writing of URL. Trouble is, I'm now a bit confused where to put the (lift) index.html in the webapp and/or what I need to change in Boot.scala. Scala plays nicely with Java, and I'd like to be able to get web frameworks playing nicely as well. I've already cobbled together spring/gwt/restlet/apachecxf so I guess I'm a glutton for punishment;) I suspect there's quite a few people want to integrate Lift with their pre-existing webapps, so I'm hoping somebody has solved it already.

[Lift] Re: execute code when browser is closed
You are correct that Comet is a way to update information after the page is
loaded. I think there's a simpler way using ajax, but I haven't explored those
areas of Lift yet. But meanwhile you need to have the xml specifying the comet
actor be dynamic. So you need to have that xml be generated by a snippet. A
snippet is an XML to XML function.

[Lift] Re: Need two classes to inherit from one model, database design and view issues
Lift doesn't really support this directly in Mapper, although you could write a single class and use a discriminator value field. If there's not a relational need for both types to have a common superclass it would probably be simpler to just build two distinct classes and have them sit in different tables. IIRC, you *could* have a common base class with common fields for both types and just override the dbTableName def on the Meta object for each. If you're using JPA you can easily do this with an inheritance mapping.

I checked out the post with David and Steve Yen corresponding but I am still at a loss and am curious if any progress has been made in this direction. So, here goes. I am creating a website which will need two types of users: students and providers. In a traditional java setting I would create a user class (or interface) and then create two classes which inherited from the user. Is this the best course in scala too, using the extends and with modifiers? If that is indeed the best way (which I suspect it is), what the best way to map this in the DB? Would it be best to keep a type column and then have it set to one or the other? Etc. The second question is how to work with the view. The display will be very different depending on which type of user one is and so I figure there will be some serious routing logic involved or at least logic built into snippets in the view. I guess the overarching question is: Is there a preferred way to go about doing this (like a recipe in rails or some such), or am I kind of out on my own?

I am creating a website which will need two types of users: students and providers. In a traditional java setting I would create a user class (or interface) and then create two classes which inherited from the user. Is this the best course in scala too, using the extends and with modifiers? If that is indeed the best way (which I suspect it is), what the best way to map this in the DB? Would it be best to keep a type column and then have it set to one or the other? Etc. The second question is how to work with the view. The display will be very different depending on which type of user one is and so I figure there will be some serious routing logic involved or at least logic built into snippets in the view. I guess the overarching question is: Is there a preferred way to go about doing this (like a recipe in rails or some such), or am I kind of out on my own?
