[Lift] Re: multiple forms on a page.
Thanks David. Here is my repository:
git://github.com/daiwhea/MapperBBS.git
In fact, I want to share this simple demo project for the newbies like
myself when the project completed.

The easiest thing to do is for you to post your project as a complete
runnable whole to GitHub (just make a public repository).
I'll clone the repository, fix the issue and you'll see the diff and have a
running project. Sound good?

Thanks Naftoli. It does save a reply to the db after I move var
localNote to before def doReply(). But It will only save reply to the
last note even when I try to reply to the note in the top section.
So, in order to see what happend, I add lift:embed what=/templates-
hidden/gbook/replyForm / no matter the note was replied or not.
When the page loaded, I saw all the textareas in each reply form has
the same reply content of the last note. But both those textareas and
submit buttons have different names. Seems lift doesn't deal the
embeded template content in the snippet properly as wished.
I also test to add eager_eval=true to the list template as:
lift:GuestBook.list eager_eval=true. But this won't help.
Thanks for your time. You're so warmhearted. ^_^
def replyNote(html: NodeSeq): NodeSeq = {
val localNote = curListNote
def doReply() = {
localNote.save
}
bind(note, html,
replyContent - SHtml.textarea(localNote.replyContent,
localNote.replyContent(_)),
submit - SHtml.submit(Reply, doReply)
)
}
private def getReplyContent(item: GuestNote) = {
if (item.repliedByAdmin == 0) {
divpNot replied by admin/pp{item.replyContent}/
plift:embed what=/templates-hidden/gbook/replyForm //div

else
divp{Replied by admin at: +item.replyTime}/pp

Re: [Lift] How to remove manyTomany children?
But this will remove the entity as well, am I right?

Just call .delete_! on the entity itself. It should automatically remove the

Also, are you trying to delete the actual entity? Clear and remove just
delete the relationship.

Hello guys,
I have a table that has a many-to-many relationship with itself.
I manage to add new entries to the relationship table using the
MapperManyToMany, but I cannot remove entries.
This is the code I am using to remove:
for (entryToRemove - entry.childEntries) {
val indexOf = entry.childEntries.indexOf(entryToRemove)
entry.childEntries.remove(indexOf)
}
entry.save
This code is supposed to remove all the entries in the relationship table,
but it does nothing.
The class I am using to define the ManyToMany table is an extension of
Mapper, not LongKeyedMapper. This is because I do not really need an extra
field just for the primary key. Could this be the problem?
Any suggestions?
Thanks in advance,
GA

Re: [Lift] Re: [lift] Lift based backend server subscribing via amqp
hi well I'm mostly going by this stack overflow post. http://stackoverflow.com/questions/1140448/what-orms-work-well-with-scala In terms of our requirements, what we want from an orm is fairly basic. Since we are not building a web application, we would want it decoupled from any other parts of such a stack. (I heard mapper depends on the http module?). We need most of the basic orm operations with ACID compliance, preferably one that requires us to write as little code as possible and includes transactionality as something we can depend upon. The database we're currently looking at is Postgresql, so ideally the ORM should be oblivious of whether or not the database is distributed. I understand it's a bit vague. In terms of what we need right now, we need ACID and On Tue, Jan 5, 2010 at 6:39 PM, Timothy Perrett timo...@getintheloop.euwrote: In what way do you mean is mapper worth it? What kind of system is it? do you need ACID or BASE? What kind of load will the system be under? Do you need it to be distributed?

Since you are using mapper, having dependency on lift-mapper should

Re: [Lift] Lift on Atmosphere
paksegu, Lift does have better comet support than Atmosphere, but it depends what your use case is and what you specifically want to do. If you chose to run lift with atmosphere you'd essentially be loosing out on some of lift's best features. As jonas says, Akka does indeed use Atmosphere to good effect, but its a different tool, for a different job IMHO (although you can run them in tandem if your use case dictates that need). So, lets try to add some clarity here by ascertaining what exactly you want to do... before this turns into a my comet is better than your comet flame war ;-) Cheers, Tim On 6 Jan 2010, at 11:29, Jonas Bonér wrote: Akka has excellent Atmosphere support.

Re: [Lift] Re: QueryParams and joins
Ok, few points:
1. Full, Box etc. have a different package location now. Ensure import
net.liftweb.common._ wherever you have Full, Box etc.
2. scala.version should be 2.7.7
scala.version2.7.7/scala.version
3. scala-library dependency is redundant. You can remove that.
4. This shouldn't affect your compilation either. jetty version range
should be [6.1.6,7.0)
version[6.1.6,7.0)/version

Re: [Lift] Lift on Atmosphere
Yes, if you constantly change containers, then there is value in Atmosphere for that as it does leverage the native APIs for the container. We [lift] are waiting for servlet 3.0 to standardise the comet API - whilst its debatable if that will prove as an api standardisation solution, it should level the playing field somewhat - right now the different containers are all doing different things in different ways. Essentially lift uses special classes within Jetty (the continuation API) to make comet scalable... there is nothing stopping comet working in other containers with lift, the only restriction is that it does not use the native container API so it's essentially thread based - to that end, if you have a lot of connections things could get sticky. Lift has things that Atmosphere does not have (yet) like the multiplex support, and object delta'ing... perhaps other comet frameworks will get this in the future, but right now, using Jetty is not a deal breaker for most of our users. I guess its only really an issue if you have a heavy investment in something that is not jetty. However, I would stress that lift is an excellent framework even if your not using comet and that would of course deploy without any issues in any container. I actually had a discussion with Jean-Francois at Devoxx this year about Atmosphere and Lift ;-) Cheers, Tim On 6 Jan 2010, at 12:40, Paul Sandoz wrote: On Jan 6, 2010, at 12:49 PM, Timothy Perrett wrote: paksegu, Lift does have better comet support than Atmosphere, but it depends what your use case is and what you specifically want to do.

[Lift] issue with sitemap submenus ?
Hi liftweb-list ! Happy New Year to all ! Well, I have an issue with sitemap submenus. Using the following code : val entries = SiteMap(Menu(Loc(Home, index :: Nil , ?(Home))), Menu(Loc(Authors, authors :: list :: Nil, ?(Author List)), * Menu(Loc(Test, authors :: test :: Nil, ?(Author Test,* Menu(Loc(Add Author, authors :: add :: Nil, ?(Add Author), Hidden)), Menu(Loc(Books, books :: list :: Nil, ?(Book List))), Menu(Loc(Add Book, books :: add :: Nil, ?(Add Book), Hidden)), Menu(Loc(BookSearch, books :: search :: Nil, ?(Book Search Expected result : - the menu is displayed and a Author Test entry is present * Home * Author List * * Author Test* * Book List * Book Search Current result : - the menu is displayed but no Author Test entry is present * Home * Author List * Book List * Book Search Before the last mvn -U xxx my submenis where displayed correctly. Is there a known issue or am I missing something ? To reproduce the problem : - http://github.com/jlcanela/scalajpademo - change Boot.scala (line 53) and use the modified entries sitemap -- Jean-Luc Canela jlcane...@gmail.com -- You received this message because you are subscribed to the Google Groups "Lift" group.

As Tim points out, Lift has a number of advantages in its Comet support: - Multiplexing -- you can have many Comet components on a given page and they all talk over a single long poll. You can see this at http://demo.liftweb.com. Both the clock and the chat component are Comet. Neither piece of code was special or required knowledge of the other. - Connection saturation detection -- Lift will avoid connection saturation by only allowing a single long poll to be active at once. If a second connection (this is tunable and it's on my to-do list to make it browser tunable as Chrome has more than 2 connections per server) is opened from the browser, Lift will automatically terminate the long poll. - DNS wildcard support -- To avoid the connection saturation issue, you can have the long poll done on a DNS wildcarded server and tune the long poll connection termination logic. This allows many different browser tabs to have open long polls. The server name is automatically changed on each page reload and the actual client-side and server-side components are unchanged (that means the app developer doesn't have to worry about this part of the plumbing.)

If a second connection (this is tunable and it's on my to-do list to make it browser tunable as Chrome has more than 2 connections per server) is opened from the browser, Lift will automatically terminate the long poll. DNS wildcard support -- To avoid the connection saturation issue, you can have the long poll done on a DNS wildcarded server and tune the long poll connection termination logic. This allows many different browser tabs to have open long polls. The server name is automatically changed on each page reload and the actual client-side and server-side components are unchanged (that means the app developer doesn't have to worry about this part of the plumbing.) I am not suggesting Atmosphere can or should be utilized as a replacement for the useful features you enumerate. I think the area where Atmosphere can provide value to lift is scalable async support for many Web/App servers.

We [lift] are waiting for servlet 3.0 to standardise the comet API - whilst its debatable if that will prove as an api standardisation solution, it should level the playing field somewhat - right now the different containers are all doing different things in different ways. Marius is actively working on an abstraction of the thread dropping so that other containers that use different APIs can be plugged into Lift (or vice versa) because the Servlet 3.0 spec is taking forever. OK. Servlet 3.0 spec is now finalized, meaning there is at least one implementation (in GlassFish v3) but i guess it may take time for others to arrive. Are the async features of Servlet 3.0 sufficient for lift's requirements? Yes and it will be supported by the work Marius is currently doing. Essentially lift uses special classes within Jetty (the continuation API) to make comet scalable... there is nothing stopping comet working in other containers with lift, the only restriction is that it does not use the native container API so it's essentially thread based - to that end, if you have a lot of connections things could get sticky. Lift has things that Atmosphere does not have (yet) like the multiplex support, and object delta'ing... perhaps other comet frameworks will get this in the future, but right now, using Jetty is not a deal breaker for most of our users. I guess its only really an issue if you have a heavy investment in something that is not jetty. However, I would stress that lift is an excellent framework even if your not using comet and that would of course deploy without any issues in any container. As Tim points out, Lift has a number of advantages in its Comet support: - Multiplexing -- you can have many Comet components on a given page and they all talk over a single long poll. You can see this at http://demo.liftweb.com. Both the clock and the chat component are Comet. Neither piece of code was special or required knowledge of the other. - Connection saturation detection -- Lift will avoid connection saturation by only allowing a single long poll to be active at once. If a second connection (this is tunable and it's on my to-do list to make it browser tunable as Chrome has more than 2 connections per server) is opened from the browser, Lift will automatically terminate the long poll. - DNS wildcard support -- To avoid the connection saturation issue, you can have the long poll done on a DNS wildcarded server and tune the long poll connection termination logic.

I am not suggesting Atmosphere can or should be utilized as a replacement for the useful features you enumerate. I think the area where Atmosphere can provide value to lift is scalable async support for many Web/App servers. To date, the large Lift comet users have been using Jetty with success. If there is demand for Lift's Comet support on non-Servlet 3.0 platforms, we'll look into Atmosphere integration.

It smoothly integrates features of object-oriented and functional languages. This workshop is a forum for researchers and practitioners to share new ideas and results of interest to the Scala community. The first workshop will be held at EPFL in Lausanne, Switzerland, on Thursday 15 April 2010, co-located with Scala Days 2010 (15-16 April). We seek papers on topics related to Scala, including (but not limited to): 1. Language design and implementation -- language extensions, optimization, and performance evaluation. 2. Library design and implementation patterns for extending Scala -- embedded domain-specific languages, combining language features, generic and meta-programming. 3.Formal techniques for Scala-like programs -- formalizations of the language, type system, and semantics, formalizing proposed language extensions and variants, dependent object types, type and effect systems. 4. Concurrent and distributed programming -- libraries, frameworks, language extensions, programming paradigms: (Actors, STM, ...), performance evaluation, experimental results. 5. Safety and reliability -- pluggable type systems, contracts, static analysis and verification, runtime monitoring. 6. Tools -- development environments, debuggers, refactoring tools, testing frameworks. 7.

Is there not a central place to get the user session with all the values stored? In Java-land you can get/put values into the session. This has all the disadvantages of SessionVars and more. First, your keys (the names of your things) are strewn all over your code, but they are just Strings so if you change a name, you have to look through all your source code for the same String to change the key. This is no different than having the SessionVar declarations all over your code. Second, the get/put mechanism is not type-safe. You can associate anything with a key and when you pull it out, you better hope that both the putter and the getter agree on what the type should be. On the other hand, SessionVars are type safe. Third, with the get/put mechanism, you have to roll your own is the value set? logic (which might be null-based or some other mechanism might be used), where as with SessionVars, you have the lazy creation logic built right into the SessionVar. So, if you'd like to propose a mechanism that somehow centralizes the access to session-related information and doesn't suffer from the above issues, I'm all ears.

[Lift] Example project -- Image gallery
I've put the image gallery code I've been working on up at: http://github.com/jimwise/shared as a runnable project, both in hope that it will be useful to other people learning lift, and in hope of some (gentle) pointers as to what I could do better with this. Oh, one caveat -- I've set Jetty to run on port 9080 within this code, so use accordingly when playing with this. This code, building on David Pollak's image upload example, provides an image gallery with support for uploading, renaming, categorizing and deleting images, as well as browsing uploaded images by category. This is still very much a work in progress -- next steps from where I'm sitting are: a.) some corner cases of form validation -- don't allow categories to be created with a '/' in their name, as this breaks the URL rewrites b.) Ajax, Ajax, Ajax c.) make it easier to use this within a larger project -- this is already split into a separate package hierarchy from the surrounding project, but I'd like to follow the ProtoUser stuff in, eg, providing a canned Sitemap fragment for a surrounding project to use. d.) require a logged in user to upload or edit, but anyone can view (easy enough to add -- I've done it in other code -- but I haven't done it here) e.) reduce the number of queries this makes -- it's not too heavy, but some convenience functions encapsulating joins could still save some. Anyway, I'd love any thoughts on what I could be doing differently here, and hope this helps anyone else who is, like me, just starting out with lift. -- Jim Wise jw...@draga.com pgpOv3lbCKD7M.pgp Description: PGP signature
Re: [Lift] Re: SessionVars in different snippets
I don't know if it's a common practice but I usually keep all my SessionVars
in the same module (aka singleton object) for easy access:
/** All session variables */
object Session {
private def currentWeekReq = S.param(currentWeek).map(Week.parse(_))
object currentWeek extends SessionVar[Week](currentWeekReq openOr
(Week())) {
override def is = currentWeekReq openOr super.is
}
object latestEntry extends SessionVar(latestEntry)
object editEntry extends SessionVar(editEntry)
object failedEntry extends SessionVar(failedEntry)
/* etc... */
}
then I just import Session._ wherever needed.

Re: [Lift] Example project -- Image gallery
Thanks for sharing! Double thanks for spelling my last name correctly!! On Wed, Jan 6, 2010 at 9:12 AM, Jim Wise jw...@draga.com wrote: I've put the image gallery code I've been working on up at: http://github.com/jimwise/shared as a runnable project, both in hope that it will be useful to other people learning lift, and in hope of some (gentle) pointers as to what I could do better with this. Oh, one caveat -- I've set Jetty to run on port 9080 within this code, so use accordingly when playing with this. This code, building on David Pollak's image upload example, provides an image gallery with support for uploading, renaming, categorizing and deleting images, as well as browsing uploaded images by category. This is still very much a work in progress -- next steps from where I'm sitting are: a.) some corner cases of form validation -- don't allow categories to be created with a '/' in their name, as this breaks the URL rewrites b.) Ajax, Ajax, Ajax c.) make it easier to use this within a larger project -- this is already split into a separate package hierarchy from the surrounding project, but I'd like to follow the ProtoUser stuff in, eg, providing a canned Sitemap fragment for a surrounding project to use. d.) require a logged in user to upload or edit, but anyone can view (easy enough to add -- I've done it in other code -- but I haven't done it here) e.) reduce the number of queries this makes -- it's not too heavy, but some convenience functions encapsulating joins could still save some. Anyway, I'd love any thoughts on what I could be doing differently here, and hope this helps anyone else who is, like me, just starting out with lift. -- Jim Wise jw...@draga.com -- Lift, the simply functional web framework http://liftweb.net Beginning Scala http://www.apress.com/book/view/1430219890 Follow me: http://twitter.com/dpp Surf the harmonics -- You received this message because you are subscribed to the Google Groups "Lift" group.

Thanks. I've committed fixes to http://github.com/dpp/MapperBBS
Basically, rather than doing the var thing and snippet thing, I just loaded
and bound the template. It gets the job done and I prefer to explicitly
bind things and keeping state on the stack rather than in a var.

Thanks Naftoli. It does save a reply to the db after I move var
localNote to before def doReply(). But It will only save reply to the
last note even when I try to reply to the note in the top section.
So, in order to see what happend, I add lift:embed what=/templates-
hidden/gbook/replyForm / no matter the note was replied or not.
When the page loaded, I saw all the textareas in each reply form has
the same reply content of the last note. But both those textareas and
submit buttons have different names. Seems lift doesn't deal the
embeded template content in the snippet properly as wished.
I also test to add eager_eval=true to the list template as:
lift:GuestBook.list eager_eval=true. But this won't help.
Thanks for your time. You're so warmhearted. ^_^

[Lift] Re: Lift on Atmosphere

We [lift] are waiting for servlet 3.0 to standardise the comet API - whilst its debatable if that will prove as an api standardisation solution, it should level the playing field somewhat - right now the different containers are all doing different things in different ways. Marius is actively working on an abstraction of the thread dropping so that other containers that use different APIs can be plugged into Lift (or vice versa) because the Servlet 3.0 spec is taking forever. OK. Servlet 3.0 spec is now finalized, meaning there is at least one implementation (in GlassFish v3) but i guess it may take time for others to arrive. Are the async features of Servlet 3.0 sufficient for lift's requirements? Yes and it will be supported by the work Marius is currently doing. Essentially lift uses special classes within Jetty (the continuation API) to make comet scalable... there is nothing stopping comet working in other containers with lift, the only restriction is that it does not use the native container API so it's essentially thread based - to that end, if you have a lot of connections things could get sticky. Lift has things that Atmosphere does not have (yet) like the multiplex support, and object delta'ing... perhaps other comet frameworks will get this in the future, but right now, using Jetty is not a deal breaker for most of our users. I guess its only really an issue if you have a heavy investment in something that is not jetty. However, I would stress that lift is an excellent framework even if your not using comet and that would of course deploy without any issues in any container. As Tim points out, Lift has a number of advantages in its Comet support: - Multiplexing -- you can have many Comet components on a given page and they all talk over a single long poll. You can see this at http://demo.liftweb.com. Both the clock and the chat component are Comet. Neither piece of code was special or required knowledge of the other. - Connection saturation detection -- Lift will avoid connection saturation by only allowing a single long poll to be active at once. If a second connection (this is tunable and it's on my to-do list to make it browser tunable as Chrome has more than 2 connections per server) is opened from the browser, Lift will automatically terminate the long poll. - DNS wildcard support -- To avoid the connection saturation issue, you can have the long poll done on a DNS wildcarded server and tune the long poll connection termination logic. This allows many different browser tabs to have open long polls. The server name is automatically changed on each page reload and the actual client-side and server-side components are unchanged (that means the app developer doesn't have to worry about this part of the plumbing.) I am not suggesting Atmosphere can or should be utilized as a replacement for the useful features you enumerate. I think the area where Atmosphere can provide value to lift is scalable async support for many Web/App servers. To date, the large Lift comet users have been using Jetty with success. If there is demand for Lift's Comet support on non-Servlet 3.0 platforms, we'll look into Atmosphere integration. With the suspend/resume decoupling/abstraction that is in progress (the first phase is done and awaiting committer's approval on reviewboard) should be quite easy to allow such integration. Next step is to implement Jetty 7 support. Thanks, David Paul. -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] Mapper question / autogenerate some number
Thanks for your answer!! You can use mapper by itself. There's a dependency on lift webkit I believe. There might be some other issues, as i don't if anyone is using it that way. This is perfectly working As for the number, are you talking about a userId? Why would you think you can't set an arbitrary field in Mapper? no, it is not a userId, just think of it as some string. Let's call it userSpecialString for the moment. I know that I can set some field but my problem is that when *storing a new user in the database*, the system should: 1) start transaction 2) generate special number/string from database 3) set userSpecialString to this generated thing 4) store new user in the database 5) end transaction Steps 2-4 are no problem. My problem is how to do this in one transaction (steps 1 and 5) and where the best place is so that steps 1-5 automatically happen when calling newUser.save() Julian On Wed, Jan 6, 2010 at 11:11 AM, Julian Backes julianbac...@googlemail.com mailto:julianbac...@googlemail.com wrote: Does really nobody know something about my problem?

believe. There might be some other issues, as i don't if anyone is
using it that way.
This is perfectly working
As for the number, are you talking about a userId? Why would you think
you can't set an arbitrary field in Mapper?
no, it is not a userId, just think of it as some string. Let's call it
userSpecialString for the moment. I know that I can set some field but my
problem is that when *storing a new user in the database*, the system
should:
1) start transaction
2) generate special number/string from database
3) set userSpecialString to this generated thing
4) store new user in the database
5) end transaction
In this previous question:
http://old.nabble.com/%28Newbie-Question%29-How-to-do-simple-transaction-with-mapper--td26191398.html
I find the following:
import net.liftweb.*mapper*.{DB, DefaultConnectionIdentifier}
DB.use(DefaultConnectionIdentifier) { conn =
conn.setAutoCommit(false)
... // CRUDs
if(success) conn.commit
else conn.rollback
conn.setAutoCommit(true)
}
Have you tried something like this?
Steps 2-4 are no problem. My problem is how to do this in one transaction
(steps 1 and 5) and where the best place is so that steps 1-5 automatically
happen when calling newUser.save()

Hi,
I have the following problem:
For simplicity, assume I want to store users in the database.
Before
storing a user the first time in the database (using
someNewUser.save),
I want to create a special unique number for this user (which we
need in
our company) and store this number together with the new user. This
number is based on several values and some of them need to be
read from
the database.
My first idea was to add something to beforeCreate in the meta
object
but I'm not sure how to do the computation of the number
together with
the save operation in one transaction (which is absolutely
necessary)?
And are there better places to do this?
I read something about putting the whole request in one
transaction but
this is not what I want. I'm currently only using the Mapper stuff
(because I want a pure scala ORM) and not the whole Lift framework.
Thanks in advance,
Julian

I read that post but I still have the problem that I don't know where to
integrate this. Override the save() function of the user mapper class?
Or override the save() function of the meta user mapper class? Or add
something to the beforeCreate() handlers? This last case
(beforeCreate()) does not work in my opinion because I cannot start a
transaction there that wraps the whole create process...

It may not be an issue for some applications, but technically it is still better to avoid blocking a thread. The idea would be to use Atmosphere CPR to remove that limitation and instead use Atmosphere so if deployed on Tomcat, Tomcat AOI will be used.

[Lift] Re: Example project -- Image gallery
Thanks for sharing this, it's very useful and helpful to us (beginner). Cheers, Neil On Jan 7, 1:20 am, David Pollak feeder.of.the.be...@gmail.com wrote: Thanks for sharing! Double thanks for spelling my last name correctly!!

Oh, one caveat -- I've set Jetty to run on port 9080 within this code, so use accordingly when playing with this. This code, building on David Pollak's image upload example, provides an image gallery with support for uploading, renaming, categorizing and deleting images, as well as browsing uploaded images by category. This is still very much a work in progress -- next steps from where I'm sitting are: a.) some corner cases of form validation -- don't allow categories to be created with a '/' in their name, as this breaks the URL rewrites b.) Ajax, Ajax, Ajax c.) make it easier to use this within a larger project -- this is already split into a separate package hierarchy from the surrounding project, but I'd like to follow the ProtoUser stuff in, eg, providing a canned Sitemap fragment for a surrounding project to use. d.) require a logged in user to upload or edit, but anyone can view (easy enough to add -- I've done it in other code -- but I haven't done it here) e.) reduce the number of queries this makes -- it's not too heavy, but some convenience functions encapsulating joins could still save some. Anyway, I'd love any thoughts on what I could be doing differently here, and hope this helps anyone else who is, like me, just starting out with lift. -- Jim Wise jw...@draga.com -- Lift, the simply functional web frameworkhttp://liftweb.net Beginning Scalahttp://www.apress.com/book/view/1430219890 Follow me:http://twitter.com/dpp Surf the harmonics -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: multiple forms on a page.
Thanks David. It works as wished now. ^_^

Thanks David. Here is my repository:

In fact, I want to share this simple demo project for the newbies like
myself when the project completed.
Thanks. I've committed fixes tohttp://github.com/dpp/MapperBBS
Basically, rather than doing the var thing and snippet thing, I just loaded
and bound the template. It gets the job done and I prefer to explicitly
bind things and keeping state on the stack rather than in a var.

The easiest thing to do is for you to post your project as a complete
runnable whole to GitHub (just make a public repository).
I'll clone the repository, fix the issue and you'll see the diff and have
a
running project. Sound good?

Just move var localNote ... to before def doReply() ...

Thanks Naftoli. It does save a reply to the db after I move var
localNote to before def doReply(). But It will only save reply to the
last note even when I try to reply to the note in the top section.
So, in order to see what happend, I add lift:embed what=/templates-
hidden/gbook/replyForm / no matter the note was replied or not.
When the page loaded, I saw all the textareas in each reply form has
the same reply content of the last note. But both those textareas and
submit buttons have different names. Seems lift doesn't deal the
embeded template content in the snippet properly as wished.
I also test to add eager_eval=true to the list template as:
lift:GuestBook.list eager_eval=true. But this won't help.
Thanks for your time. You're so warmhearted. ^_^
def replyNote(html: NodeSeq): NodeSeq = {
val localNote = curListNote
def doReply() = {
localNote.save
}
bind(note, html,
replyContent - SHtml.textarea(localNote.replyContent,
localNote.replyContent(_)),
submit - SHtml.submit(Reply, doReply)
)
}
private def getReplyContent(item: GuestNote) = {
if (item.repliedByAdmin == 0) {
divpNot replied by admin/pp{item.replyContent}/
plift:embed what=/templates-hidden/gbook/replyForm //div
}
else
divp{Replied by admin at: +item.replyTime}/pp
{item.replyContent}/plift:embed what=/templates-hidden/gbook/
replyForm //div
}

[Lift] problems with file upload inside modal
Hi guys,
I'm stuck with this problem for a few days now and need help. I want
users to be able to upload a ZIP file. When I embed this functionality
directly in the page it works flawlessly - but I need to put it into a
modal and that's were the trouble starts.
When I submit the form it executes correctly but it prints (!) the
response to the browser:
try{jQuery(#lift__noticesContainer__).each(function(i)
{this.innerHTML = div class=\success\ulliThanks for the
upload!/li/ul /div;});} catch (e) {}
The code looks right but it shouldn't print to the screen. What am I
doing wrong?
#
My current progress (using M8):
HTML:
lift:SourceUpload form=post multipart=true
fieldset style=width: 90%; margin: 0 auto
strongAt first/strong select the zip file upload:file/
br/br/
and strongthen/strong push
input type=submit value=upload!/
/fieldset
/lift:SourceUpload
CODE:
def request(in: NodeSeq) = // opens file upload modal
ajaxButton(in, () = S.runTemplate(List(/katas/share)).
map(ns = ModalDialog(ns)) openOr Alert(Internal
error: Couldn't find template!))
def render(in: NodeSeq): NodeSeq = bind(upload, file -
SHtml.fileUpload(processFile _))
Cheers,
Stephan
