Re: [Lift] method call from out of nowhere
It is called outside from an Actor, everytime a new item is created.
thanks.
Where is joinOtherOrders()called within your code?

Re: [Lift] Re: method call from out of nowhere
Hi Marius,
the method is called from an Actor, everytime a new order is created. I
did override def afterCreate in my LimitOrder MetaObject.
thanks.
In your code in what conditions joinOtherOrders gets called ?

Hi Tim, Hannes,
Firstly, I really, really wouldn't write your code like that...
Things of note:
- two defs inside defs... you usually wouldnt do this without a good reason
(like SHtml.submit(whatever _))
The two defs only make sence together, that's why I put them together in
one def. I think that's encapsulation... - dont use while loops. period.
you have a List[T], use foreach if you have a unit operation
Yeah, that's true. But the problem is, that my logic requires to stop
the iteration at some point. How I gonna do that with a foreach construct?
def joinAll(orders: List[LimitOrder]): Unit =
orders.foreach(order = {
// your logic here
})
You should look to remove a lot of that boiler plate... its looks very
javaish and mutable. Generally speaking, scala programmers avoid mutable
state like one would avoid bubonic plague.
Your totally right! Its mutable, cause its changing the state of my
objects. But that's necessary at this point. Before worrying about the
errors, id change your code, then take another look... its almost certainly
this bad organisation causing the issues.
I agree with you, that this is not the most beautiful code I every saw,
but I believe that the things you mentioned are not interfering with the
problem I'm facing. At least not because of a while-loop and some inner
local defs.
Cheers, Tim

If you want encapsulation, because they only make sense together,
stick them in a trait - something about this inner def for your use
case feels very wrong.
Yeah, that's true. But the problem is, that my logic requires to stop
the iteration at some point. How I gonna do that with a foreach construct?
This is where I think you should evaluate your thinking. stoping
iteration is a java way of working... in scala i would typically
filter the list before iterating on it:
orders.filter(predicate).foreach(order = { ... })
That seems to be a lot neater - my point was more go look at the
other method options on List[T] rather than the code i show here is
the defacto way for your use case.
OK, I'm going to figure out, how to transform the while-loop into a
foreach
I agree with you, that this is not the most beautiful code I every saw,

Are you calling this code in a try, catch, finally block by any

Re: [Lift] method call from out of nowhere
Hi David,
In my LimitOrder Meta Object, I did:
override def afterCreate
to inform an Actor, everytime a new Order is created. The Actor than
calls the joinOtherOrders method.
#
I think I understand it now. Cause I'm creating new orders inside the
loop at some point. But still I don' t really know, why it gets called
after the old scope of joinOtherOrders ends...
thanks.

Re: [Lift] Feedback on wizard code
On Sun, Nov 29, 2009 at 3:57 PM, Timothy Perrett timo...@getintheloop.euwrote: David, So I took a close look at the lift-wizard code with a view to do what we discussed on the committers call. From that, I have the following feedback and questions: - Wizard.scala, L192... You have hardcoded html tables; IMHO, these need to go, ASAP! The code looks through a list of places for the template and only returns the hard-coded XML if *a template is not found anywhere else*. The template is automatically included in the archetype. But, I am absolutely unwilling to have wizard code that doesn't work because the developer didn't include a template. One way or another, a graceful degradation will happen. This will not change. Id suggest replacing them with a CSS div from blueprint or similar. I do however see that you can override this using wizard-all.html in templates-hidden... pretty cool, but not obvious - shall i document this more in the comments? Feel free to document the process for selecting a template as well as the bind points in the template. - There is a lot of code in Wizard.scala; it would be easier to navigate if it were broken into different files - the whole thing needs a lot more commenting. Im happy to add this if you want...? It's possible to move StringField and IntField to another file. The rest of the stuff is part of the single Wizard trait and it's be difficult/impossible to break this into multiple files without losing protection scopes. - Mapper appears to be a hard dependency It's not a hard dependency. You are not *required* to use a JDBC transaction. if you want a persistable wizard as it relies on the mapper transaction block... It is possible to do the common use case of explicitly using DB's transations. While DB is part of mapper, it's conceptually a vendor of JDBC connections and is used by the JDBC stuff in Record as well. Wizard stuff is run within the scope of an HTTP request and any transaction stuff you have as part of that HTTP request will surround the execution of the Wizard's finish block. could this be made more generic so the persistence mech could be JPA etc? Is it possible to do a Mapper transaction using the JTA module? - In order to load the wizard dynamically from some serialised form (xml, json or whatever) would I be right in saying that its a matter of creating a subtype that overrides the following declarations: + Wizard.screens + Wizard#Screen.screenFields + Wizard#Screen#Field.validate Yep.

Re: [Lift] Re: vscaladoc broken?
Short answer: Use mvn site for a couple of days to have the package link defs work, but ideally mvn scala:doc should be consistent. I'll fix that, give me a day or two please. Long answer: mvn site picks up plugin settings from reporting section and mvn scala:doc picks up plugin settings from build section. The trick (jvmArg -DpackageLinkDefs) is done in the maven-scala-plugin configuration in the reporting section. Per Maven's documentation build plugin settings (and thus config) should be picked up from their corresponding settings in reporting section (odd, but true). Strangely, that's happening for all the config elements except for jvmArgs/. So I'll go ahead and duplicate jvmArgs/ section in both places:report plugin and build plugin. Pain: Next up, you, or somebody else who is regularly doing mvn scala:doc locally (and want to stay offline) would find that with mvn site (or mvn scala:doc when the fix is in) you end up having the click thru to different package classes land up somewhere in http://scala-tools.org/mvnsites-snapshots/ instead of local filesystem. This is because, by default vscaladoc.links.liftweb.baseurl is set to http://scala-tools.org/mvnsites-snapshots/liftweb. Adjust this using -Dvscaladoc.links.liftweb.baseurl=local_lift_base during mvn site to circumvent that.

[Lift] Re: A sensible AJAX approach
David,
Thanks a bunch. Your solution is one I was trying to implement but
wasn't quite
sure how until you showed me that I can create an AnonFunc using
Shtml.ajaxCall.
It certainly does simplify things.
One of the issues that stymied me - and still does, frankly - is how
the ajaxCall wraps the edit function
with the correct parameter for the callback to work.
I updated the code in http://github.com/glennSilverman/treeview and
refactored it into
a MetaMegaTreeItem trait to easily add these features to any Mapper
object. Maybe
some Lift committer might find the ideas involved here usefull enough
to include something
similar in a future release of Lift.

Glenn,
The issue is that you were creating call-back functions during an API call
(rather than as part of Lift's HTML/Ajax/Comet pipeline).
In general, I think this is very bad design. I'd strongly recommend using
the Ajax/Json call facilities built into Lift. You get a pile of things for
free including securing calls (you don't need to keep a lot of state
client-side).
So, your code looks like:
def buildTree(in:NodeSeq):NodeSeq = {
val func = AnonFunc( SHtml.ajaxCall(JsRaw(this.id), (id: String) =
SetHtml(role_edit, Role.find(id).map(edit) openOr
NodeSeq.Empty))._2 )
TreeView(tree, JsObj((persist, location), (toggle, func)),
loadTree, loadNode)
}
Also, you might want to look at S.hostAndPort for calculating the current
server. Also, think about using the map() call rather than pattern matching
on Full/_.
Also, there's no need to register API calls in SiteMap
I'll update your app and push code tohttp://github.com/dpp/treeview

The statement that all functions are bound to the current state in the

It's just a basic lift archetype with a Role.scala added to the mapper

[Lift] Re: How to get the servlet context
Ahh so you want direct links to those files. Still you can do something else. Point your URI's from your page to a specific uri such as /myapp/serve/myimage.jpg. You intercept requests to myapp :: serve :: _ using a DispatchPF. The dispatch PF knows about your folder location (presumably from a config file) and reads myimage.jpg from that path on the file system. Hence you can read the File and send it to the client. I think you can use Lift's StreamResponse or you can build your own LiftResponse that returns a file using proper Content-Type. Another approach would be to use a reverse proxy server in front of your Lift application (this is a common production deployment model that server static content from frontend server not app servers), your Lift application could simply write files in the document-root folder hence would be seen by the proxy server and served to the client. I used in the past both options with no problem at all for use cases not so different than yours.

Storing files inside the exploded WAR file is a tremendously bad idea. I don't think we should be helping a user do something that is going to continue to cause him pain.

Point your URI's from your page to a specific uri such as /myapp/serve/myimage.jpg. You intercept requests to myapp :: serve :: _ using a DispatchPF.

I think you can use Lift's StreamResponse or you can build your own LiftResponse that returns a file using proper Content-Type. Another approach would be to use a reverse proxy server in front of your Lift application (this is a common production deployment model that server static content from frontend server not app servers), your Lift application could simply write files in the document-root folder hence would be seen by the proxy server and served to the client.

On Fri, Nov 27, 2009 at 7:30 AM, Heiko Seeberger heiko.seeber...@googlemail.com wrote: Excellent proposal! +1 Heiko On Friday, November 27, 2009, Indrajit Raychaudhuri indraj...@gmail.com wrote: Folks, In continuation to the refactoring initiative and following up on the discussion that we had on the last committers call, here we have the next round of broad based project structure refactoring proposal. This is themed around the idea of splitting the build system into separate smaller 'projects' with clearly demarcated responsibilities between them. In the way, these projects can have independent life-cycles on their own without coming in the way of each other (but still continue to have a dependency hierarchy). Here are the set of projects to begin with: 1. framework (http://github.com/dpp/liftweb/tree/branch/framework): The regular Lift as we have today (minus lift-archetype, lift- examples, lift-misc). Thus we would have: framwork/pom.xml framwork/lift-base framwork/lift-persistence framwork/lift-modules 2. archetypes (http://github.com/dpp/liftweb/tree/branch/ archetypes): The lift-archetypes from Liftweb. archetypes/pom.xml archetypes/lift-archetype-blank archetypes/lift-archetype-basic archetypes/lift-archetype-jpa-blank-single archetypes/lift-archetype-jpa-blank archetypes/lift-archetype-jpa-basic 3. examples (http://github.com/dpp/liftweb/tree/branch/examples): The lift-archetypes from Liftweb. The big uptake for archetypes and examples is the reduction of build time for building full Lift. Individuals building Lift might not always be interested in building non ancillary packages like lift-archetypes and lift-examples. examples/pom.xml examples/example1 examples/example2 4. resources (http://github.com/dpp/liftweb/tree/branch/resources: 4a. project-parent: A pure POM based project to be canonically used by all Lift family of projects (liftweb, lift-archetype, lift-examples etc.). Lot of what has gone in liftweb/pom.xml should get moved here. Obviously, this would contain the most generic configuration that holds true for all projects of Lift (#1, #2, #3). 4b. site-skin: Lift specific site skin instead of relying on org.scala- tools.skins:scala-skin-simple 5. references (http://github.com/dpp/liftweb/tree/branch/ references): Lift documentations and presentations. These don't need to show up in the project hierarchy in the IDE. 6. installer (http://github.com/dpp/liftweb/tree/branch/installer): The usual lift-installer that is tucked inside lift-misc. Again, these are unnecessarily showing up in the project hierarchy in the IDE. I am floating the idea beforehand and would be keen to have input from committers, the pros and cons and any other general feedback before proceeding. Thoughts would be very welcome :) Cheers, Indrajit -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] How to redirect to a specify url when logged in successfully?

Hi all,
I want to redirecto to a specify URL like this /all_users when
logged in successfully via the default link,
http://localhost:8080/user_mgt/login
Is there a help method (i dont't find it) to configure it?
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,

Point your URI's from your page to a specific uri such as /myapp/serve/myimage.jpg. You intercept requests to myapp :: serve :: _ using a DispatchPF. The dispatch PF knows about your folder location (presumably from a config file) and reads myimage.jpg from that path on the file system. Hence you can read the File and send it to the client. I think you can use Lift's StreamResponse or you can build your own LiftResponse that returns a file using proper Content-Type. Another approach would be to use a reverse proxy server in front of your Lift application (this is a common production deployment model that server static content from frontend server not app servers), your Lift application could simply write files in the document-root folder hence would be seen by the proxy server and served to the client. I used in the past both options with no problem at all for use cases not so different than yours.

Re: [Lift] Multipage wizards
On Wed, Nov 25, 2009 at 12:30 AM, Jeppe Nejsum Madsen je...@ingolfs.dkwrote: David Pollak feeder.of.the.be...@gmail.com writes: Folks, I've completed the first pass at multi-page input Wizards in Lift. You can see an example at: http://demo.liftweb.net/wiz Great news! [...] The building of HTML forms from the given field type is based on the type (currently, there's support for String and Int, but more to come) and it's based on plugable functions, so you can build date pickers that are localized, etc. What needs to be done: - The naming (including the names that the various parts of the wizard bind to) need a good going-over - Support for many different input types (not just Int and String) - Feedback I've been thinking about this for a while and haven't really reached anything concrete yet, but it overlaps enough with the wizard stuff that I might just throw it out here now: I think that form handling in Lift is too cumbersome. I.e. all the building blocks are there to create great forms, but it takes too much boilerplate code to achieve a nice result. I know forms are not sexy in the ways Comet Ajax support is, but for many applications (ours included :-) it's where the major interactions with the user happens, so a good UX is essential. Here's my (ultimate) list of things that should be easy (for the developer) to do without too much fuzz: - Provide field level validations - including client side if possible - Provide form level validations - including client side - If the form contains Mapper fields, you should not have to respecify the validations - Render fields with proper markup (ie required fields should be indicated) - When a form is in error, retain values entered by the user - When a field is in error render it differently (ie red) with field specific error - Provide field level help (inline, popup etc) - Provide form level help - All fields and text should support i18n (ie both labels, text and for numeric and e.g date entries) I haven't looked closely at the wizard code yet, but it seems like it does provide some of these benefits. Some possible ideas: - Could be nice if the wizard code could be extended to generic forms. Wizards would just be a special case, with a sequence of forms and prev/next buttons etc. - I would very much like to see validations lifted to a higher level so that the same validation rule can be used for Mapper (and Record), forms wizards. - Fields should be able to emit client side validations and code - Maybe we could introduce generic form fields (ie Number, Date etc) and they could be reused by the Mapper/Record fields. In this way, they would all share the same presentation logic (ie i18n formatting for display/editing, datepickers, more advanced dialogs etc) - Much more Thoughts? Yeah this all sounds good. I'm trying to unify most of the pieces of single form inputs, validation, mapper, record and wizard. It's generally slow going. We'll soon be needing much of this in our app, so I'm willing to participate in this if there's any interest. /Jeppe -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: lift-json escaping bug
Hi,
This is from JSON RFC (http://www.ietf.org/rfc/rfc4627.txt): A JSON
text is a serialized object or array.
I checked with another parser (http://www.jsonlint.com) and it fails
too when given just JSON value:
syntax error, unexpected TNUMBER, expecting '{' or '[' at line 1
So perhaps a better error message is a proper fix here?
Cheers Joni

Mea maxima culpa! This should have occurred to me that although
deprecated, somebody still might have been using archetype:create.
The jpa related archetypes had moved to the new archetype format quite
sometime back. That made me assume the usage of archetype:generate
pretty much 'given'. In hindsight, I think that was a bad assumption!
Nonetheless, very sorry for this inconvenience. And even more, sorry for
the oversight in not sending out the **BREAKING CHANGES** email. I'll
take care of this later in the day.

Re: [Lift] method call from out of nowhere
Hi David,

mailto:hannes.flo...@gmx.li wrote:
Hi David,
In my LimitOrder Meta Object, I did:
override def afterCreate
to inform an Actor, everytime a new Order is created. The Actor
than calls the joinOtherOrders method.
#
I think I understand it now. Cause I'm creating new orders inside
the loop at some point. But still I don' t really know, why it
gets called after the old scope of joinOtherOrders ends...
Sounds to me like it's all in your application's logic. As others
have pointed out, Thread.dumpStack will let you figure out where
things are being called.
I think the biggest problem is, that its necessary in my logic to inform
the Actor, everytime a new order is created. This while-loop is an
exception to this rule. I don't think that it would be a good idea, to
change the behavior of how the Actor responds to messages, just to fix
this case, or? Or is there any chance to tell a new order NOT to inform
the Actor, even when its defined in def afterCreate ?
Also, you might want to use recursion and pattern matching to replace
your while loop (which is O(n^2) btw):
def dealWithList(in: List[Something]): Unit = in match {
case Nil = () // nothing left to do
case x :: _ if x.condition1 = x.doThing1
case x :: _ if x.condition2 = x.doThing2
case x :: xs if x.condition3 = x.doThing3 ; dealWithList(xs)
case _ :: xs = dealWithList(xs)
}
I thought about pattern matching as well, but in my first
implementation, I just wanted to get it running and change it
afterwards. Something else: I think recursion is slower than a
while-loop as long as its not tail recursive, or?
thanks.
You have the same semantics of a while loop with the ability to break
out, but the code is about your logic rather than about looping.
thanks.

val blob = ImageBlob.create.image(x).saveMe
ImageInfo.create.name
(fp.fileName).mimeType(fp.mimeType).blob(blob).saveMe
S.notice(Thanks for the upload)
S.redirectTo(/)
}
}
def render(in: NodeSeq): NodeSeq =
bind(upload, in, file - SHtml.fileUpload(saveFile _))
}
If the blob is uploaded, it's put in a row in ImageBlob and an ImageInfo row
is created to store the name and mime type. There are two different rows so
that one doesn't have to pull the whole blob back when you're checking for
the upload date.
Serving the image is similarly concise:
def serveImage: LiftRules.DispatchPF = {
case req @ Req(images :: _ :: Nil, _, GetRequest) if
findFromRequest(req).isDefined =
() = {
val info = findFromRequest(req).open_! // open is valid here because
we just tested in the guard
// Test for expiration
req.testFor304(info.date, Expires - toInternetDate(millis +
30.days)) or
// load the blob and return it
info.blob.obj.map(blob = InMemoryResponse(blob.image,
List((Last-Modified, toInternetDate(info.date.is)),
(Expires, toInternetDate(millis + 30.days)),
(Content-Type, info.mimeType.is)), Nil, 200))
}
}
If the request matches /images/xxx where xxx is a name in the ImageInfo
table, check to see if we can return a 304 (not modified). If not, we pull
the blob from the database and return it.
I hope this helps folks who are looking to manage and serve images.
Thanks,
David
