[Lift] Re: Tomcat css access problem
Hi,
your suggestion didn't work for me because I'm using url-rewrite in my
application.
Something like
http://...application/parameterA/
http://...application/parameterA/parameterB/
Therefore the relative path wouldn't match.
The CSSHelper function fixes the absolute path.
This is important because I can deploy the same package in
development / and production /applicationFolder/ environment.

Hi,
Then I guess my next question is: how do you define where your css is located?
I have a function that gives the location of my css in the following way:
def css = link href={ S.hostAndPath+/+scripts/cd.css}
rel=stylesheet type=text/css/
You shouldn't need the S.hostAndPath+/ part unless you're using
fancy redirecting like I'm doing. I call that function from my main
template. In fact, you shouldn't even need a function and could just
use link href=relativePathToFolderContainingCSS/cd.css
rel=stylesheet type=text/css/
In your case, I'd think that the
relativePathToFolderContainingCSS/cd.css would be
css/kungleNext.css, but I might be mistaken.

Hi,
you are absolutely right.
I use mvn jetty:run in my development environment to test the
application.
Than I build a package with mvn package and copy it to the tomcat
webapp directory.
Thank you,

Hi,
I'm assuming you mean deploying under jetty and tomcat. I only know
derby to be a database.
How exactly do you deploy under jetty and tomcat?
Personally, I use jetty for testing and deploy with mvn jetty:run,
while I use tomcat on the test and production servers in which case I
just drop the war file under web-apps.
Thanks,

Hi,
I'm working with 1.1 snapshot (latest) and have the following problem
with a local css reference:
If I deploy my webapp under derby the resulting html output looks
fine:
link media=screen rel=stylesheet type=text/css
href=/KungleNext-0.1-SNAPSHOT/css/kungleNext.css /
The same application deployed under tomcat produces this buggy
reference:
link media=screen rel=stylesheet type=text/css

My snippet defines the ling as follows:
...

[Lift] about QueryParams
there are two kinds of QueryParams in Lift, one uses raw sql clauses and the other not.

This means that SQL injection attacks are impossible unless there is a bug in the underlying JDBC driver.

I've been reading Exploring Lift (~Section 3.7) along with What's the
'View' folder for? from http://wiki.liftweb.net/index.php/FAQ.

The server is maven/jetty.
I'm struggling to find other reading materials/examples which highlight my
error(s); any help is appreciated. Thanks! Dan

[Lift] Newbie Question design pattern for ORM in Lift
I am using Lift 1.0 with the Mapper ORM module from Lift. I am a
newbie to Scala and Lift. I have auto-generated my ORM classes from
a .sql file. Given that these classes are auto-generated I would
prefer not to edit them directly and provide additional functionality
via inheritance.
Say I have the following...
class StatGenerated extends LongKeyedMapper[StatGenerated] with IdPK {
def getSingleton = StatGenerated
object errors extends MappedLong(this)
object hits extends MappedLong(this)
object AB extends MappedLong(this)
}
object StatGenerated extends StatGenerated with LongKeyedMetaMapper
[StatGenerated] {
override def fieldOrder = List(errors, hits)
}
class Statistics extends StatGenerated {
def GetBattingAverage(id : Long) : float = {
val stat = Stat.findByKey(id)
stat.hits/stat.AB
}
}
Now what I would like to do is work with the Statistics class as my
ORM object...
But I believe everything that is ORM related is actually of type
StatGenerated rather than Statistics. i.e. findByKey will return me a
StatGenerated rather than a Statistics class. Is there any clever way
around this that I am missing without either modifying the generated
class or duplicating code?

[Lift] Re: Modularization of Lift code
David,
Returning menu items from your init function is OK, but forces the
user
of your module to guess on function-call order, or be forced to glean
it from
the source, which he should not be required to do.
Putting code such as this, instead, in your init function helps, but
does not eliminate that problem.
val sitemap = LiftRules.siteMap match {
case Full(sm) = LiftRules.setSiteMap(SiteMap(sm.menus :::
Role.menus:_* ))
case _ = LiftRules.setSiteMap(SiteMap(Role.menus:_*))
}
With it, you can sort of standardize your call-order, requiring that
the init function
be called immediately before
S.addAround(DB.buildLoanWrapper)
in Boot,scala.
But, there is a larger issue at stake here, I fear, and that is that
true modularization
requires adherence to rules of encapsulation and complete
documentation, two things
that are problematic in Scala code (perhaps due to its power and
complexity), unlike pure OOP.
When I've written before on this subject in this group, I've gotten a
lot of examples in the small
purporting to dispute my contention, but falling short. If you know
I'm wrong, fine ... let's see it.
If you just think I am, well...think harder.

In the boot file of a new application and then everything wires up - I
couldn't think of anything more straightforward?
The vast majority of stuff in lift is done with PF's, so you can
pretty much just write them in external jars, and import them - my 3rd
part stuff usually has a lift-webkit dependency so that I can just do
the LiftRules.disptach.append stuff directly in the init method, but
its really no biggy and saves boilerplate.
So given your example, this scheme should work right?

Ummm... as far as I know, Scala is a pure OO language. Everything in Scala
is either the instance of a class (and object, but object is overloaded with
Scala's use of it as a keyword for singleton) or a method. There is nothing
else in Scala. In this way, Scala is like Smalltalk and Ruby. It's not
like Java where things exist in Java that are neither an instance nor a
method (static methods, primitive types, etc.)
There is nothing that we can't do in Scala to encapsulate anything... the
issue that I see is what do you want to encapsulate?
When I've written before on this subject in this group, I've gotten a
lot of examples in the small
purporting to dispute my contention, but falling short. If you know
I'm wrong, fine ... let's see it.
If you just think I am, well...think harder.
Let's separate Lift from Scala the language for a moment. I'm no expert in
PLT so I'm not going to argue encapsulation in Scala.
I can argue about Lift's modularization and what its limitations are.
The following things in Lift I know to be non-modular:
- Mapper: because one cannot subclass Mapper definitions, it's not really
modular. Yes, I've built (and subclassed) ProtoUser, but it's a huge hack
and anything serious (e.g., subclassing an existing mapper and *changing*
the behavior of one on the fields) is not doable with Mapper. This is
basically because I've never meant Mapper to be a serious OR mapping tool,
but more of an ActiveRecord clone where you can create a mapping between an
RDBMS and some sort of record. I use Mapper very successfully, but it's
not meant for the same things OO is meant for (subclassing) or what Mixins
are meant for.
- SiteMap: SiteMap is frozen at boot time. This means that OSGi modules
can't load and unload themselves and mutate the sitemap. Because the
sitemap is fixed at boot time, it's also not possible for a module to insert
menu items at an appropriate place in the menu hierarchy.
- LiftRules: like SiteMap, the LiftRules are fixed at boot time. It's
not possible for modules to load/unload dynamically and change the various
PFs dynamically.
I have a plan for fixing the LiftRules stuff so we can fully support OSGi
modules. I will likely extend that to supporting more dynamic sitemaps.
More broadly, every time I've had Scala code that's concrete and needed to
be made more runtime dynamic, the process has been simple, quick, and
painless. Breaking classes into traits and composing those traits into
different runtime configurations has by and large been a few minute to few
hour project. Yeah, it may be considered poor mans DI to use traits and
the cake pattern, but I find that the type safety that Scala offers makes
the small extract Scala coding effort to be worth it vs. writing more
tests/configuring more runtime stuff/the weird errors that creep into the
code despite tests.
This is not small potatoes There are plenty of languages on the dust
heap precisely because
of the extension problem.
Can you be very detailed about what kind of problems you're seeing. Maybe
the folks on this list can help you work through them and maybe we'll all
discover new Scala patterns.
Thanks,
David

[Lift] Re: Newbie Question design pattern for ORM in Lift
Thanks for the answers everyone. What David hit upon about wanting
objects to be subclassible is the conclusion I came to that would
work..if it existed. I was hoping there was a way. :(. Well, I guess
Naftoli has provided a possible solution but seems more involved than
I have the experience for.
I will resort to putting the stuff on the generated classes and let
merge tools do the rest.
Regarding sharing the codeI should be more specific in that it
parses ddl. To be honest, I hope you all are not hoping for
muchbut I will get it up on github and when I do will reply to
this thread with the location.

Back in the Scala 2.5 days, there was some talk about allowing this to

your sql generator to create a superclass that could be subclassed and have
the effect that you want.

def getSingleton = StatGenerated
object errors extends MappedLong(this)
object hits extends MappedLong(this)
object AB extends MappedLong(this)
}
object StatGenerated extends StatGenerated with LongKeyedMetaMapper
[StatGenerated] {
override def fieldOrder = List(errors, hits)
}
class Statistics extends StatGenerated {
def GetBattingAverage(id : Long) : float = {
val stat = Stat.findByKey(id)
stat.hits/stat.AB
}
}
Now what I would like to do is work with the Statistics class as my
ORM object...
But I believe everything that is ORM related is actually of type
StatGenerated rather than Statistics. i.e. findByKey will return me a
StatGenerated rather than a Statistics class. Is there any clever way
around this that I am missing without either modifying the generated
class or duplicating code?

[Lift] Re: Modularization of Lift code
David,
Besides the very detailed discussion here about the problems of Boot
initialization
and the immutability of sitemap and liftrules, that strikes me as a
sufficient
barrier to real modularization. I hadn't thought about turning
reuseable code into
traits and assigning those around in jar files until you mentioned it.
Not a bad idea.
But I wouldn't feel comfortable incorporating third-party traits in my
code unless
I had the source to fall back on.
Example of poor encapsulation - just the fact that you can encapsulate
snippets and templates. Without the
source, how can a user ever hope to incorporate those. And then, to
make them private, which is done...that's turning
a headache into a nightmare.
Yeah, as long as you work at the source-level, there is no problem.
But that, in-and-of itself, is the problem. As you
suggest, some, as yet unilluminated patterns, would be most helpful.

Putting code such as this, instead, in your init function helps, but

Where are you proposing to put this code?
With it, you can sort of standardize your call-order, requiring that
the init function
be called immediately before
Just to be precise, init() is a method on your module. It's not a function.
S.addAround(DB.buildLoanWrapper)

But, there is a larger issue at stake here, I fear, and that is that
true modularization
requires adherence to rules of encapsulation and complete
documentation, two things
that are problematic in Scala code (perhaps due to its power and
complexity), unlike pure OOP.
Ummm... as far as I know, Scala is a pure OO language. Everything in Scala
is either the instance of a class (and object, but object is overloaded with
Scala's use of it as a keyword for singleton) or a method. There is nothing
else in Scala. In this way, Scala is like Smalltalk and Ruby. It's not
like Java where things exist in Java that are neither an instance nor a
method (static methods, primitive types, etc.)
There is nothing that we can't do in Scala to encapsulate anything... the
issue that I see is what do you want to encapsulate?
When I've written before on this subject in this group, I've gotten a
lot of examples in the small
purporting to dispute my contention, but falling short. If you know
I'm wrong, fine ... let's see it.
If you just think I am, well...think harder.
Let's separate Lift from Scala the language for a moment. I'm no expert in
PLT so I'm not going to argue encapsulation in Scala.
I can argue about Lift's modularization and what its limitations are.
The following things in Lift I know to be non-modular:
- Mapper: because one cannot subclass Mapper definitions, it's not really
modular. Yes, I've built (and subclassed) ProtoUser, but it's a huge hack
and anything serious (e.g., subclassing an existing mapper and *changing*
the behavior of one on the fields) is not doable with Mapper. This is
basically because I've never meant Mapper to be a serious OR mapping tool,
but more of an ActiveRecord clone where you can create a mapping between an
RDBMS and some sort of record. I use Mapper very successfully, but it's
not meant for the same things OO is meant for (subclassing) or what Mixins
are meant for.
- SiteMap: SiteMap is frozen at boot time. This means that OSGi modules
can't load and unload themselves and mutate the sitemap. Because the
sitemap is fixed at boot time, it's also not possible for a module to
insert
menu items at an appropriate place in the menu hierarchy.
- LiftRules: like SiteMap, the LiftRules are fixed at boot time. It's
not possible for modules to load/unload dynamically and change the various
PFs dynamically.
I have a plan for fixing the LiftRules stuff so we can fully support OSGi
modules. I will likely extend that to supporting more dynamic sitemaps.
More broadly, every time I've had Scala code that's concrete and needed to
be made more runtime dynamic, the process has been simple, quick, and
painless. Breaking classes into traits and composing those traits into
different runtime configurations has by and large been a few minute to few
hour project. Yeah,
[Lift] weirdness with stateful snippets and multiple forms on the page
Are stateful snippets considered a good way to do multi-step wizard like interfaces? They seem like a good fit, but I'm running into 1 annoying problem. I'm seeting things up so in my .html file I have something like this: lift:MyPage.stepOne form=POST // HTML for step 1 /lift:MyPage.stepOne lift:MyPage.stepTwo // HTML for step 2 /lift:MyPage.stepTwo Then in the MyPage StatefulSnippet I return NodeSeq.Empty for 1 step, and actual contents for the other. The only issue is that for the inactive steps HTML like the following gets sent to the browser: form action=/my_page method=postinput name=F110858803410EI0 type=hidden value=true //form This isn't a huge deal really, but it's kind of annoying. It almost seems like that a lift: element with a form attribute shouldn't generate the form if the snippet function returns NodeSeq.Empty -harryh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

At first, I struggled with trying to pull the request parameter (the url looks like this - /person/1) into my CometActor, and then I found a message on the lift board that talked about the scope mismatch between the request scope and a CometActor, and recommends setting a session variable that the CometActor then reads. The scope mismatch makes sense to me, so I tried the suggested way of doing it, which worked. However, now when I go back to the home page and select another person to view messages for, I still see the the old messages. After some testing, it appears that CometActors on the same page are not re-created if there is one already active. I can't seem to find any method that gets called on it when the page is rendered either, and I am not sure how to update the state of the CometActor so that it retrieves the proper messages. Is there any documentation or examples for using CometActors in conjunction with a request parameter like that? Or is there a better way altogether for me to be doing this?

[Lift] Re: Modularization of Lift code

David,
Besides the very detailed discussion here about the problems of Boot
initialization
and the immutability of sitemap and liftrules, that strikes me as a
sufficient
barrier to real modularization.
Are you talking about modularization of web apps? Are you talking about
being able to plop in a JAR file and do one or two bits of configuration
and have that JAR's features be part of your app? If you are, with the
exception of the where do my menu items go issue, as long as you can do
the configuration in Boot, Lift allows for fully modular apps.
Rather than complaining the Lift doesn't offer what you need, please define
what you need in very specific terms (I need to intercept a GET request to a
URL, I need to intercept requests to a URL if certain conditions are met, I
need to include a tag in view code that invokes code in my module, etc.) or
point to another framework that allows for this plugin modularization.
I hadn't thought about turning
reuseable code into
traits and assigning those around in jar files until you mentioned it.
Not a bad idea.
But I wouldn't feel comfortable incorporating third-party traits in my
code unless
I had the source to fall back on.
Why are traits any different than objects that you subclass? As far as I
can tell, traits simply give you nearly multiple inheritance without the
headaches. Why would you be any less willing to mix in a trait than to
subclass a class provided by another library?
Example of poor encapsulation - just the fact that you can encapsulate
snippets and templates. Without the
source, how can a user ever hope to incorporate those.
I think that snippets are a near perfect encapsulation mechanism. They are
simply a transformation of XHTML - XHTML. What could be more straight
forward? What could be more encapsulated? Further, Lift's mechanism of
associating HTML elements with functions means that there's no need to have
special URLs to handle forms or anything else. My snippet can generate a
form that will be processed if it is submitted back to the server, no matter
what URL the form is submitted to. In Rails and other MVC frameworks, the
POST/GET must be done to a specific controller in order for the parameters
to be correctly processed. Why does this matter?
Well, in the ESME codebase, I just created an authentication plugin
mechanism that allows a plugin to define a part of a form that is to be
filled in as part of the signup process. The signup process doesn't know
anything about the plugin or what fields the plugin needs. The snippet that
handles the signup simply binds one element to the plugins part of the
sign-up. The plugin manages its own portion of the form, manages its own
validation, manages its own saving, all without having to register as being
part of the controller. This is highly modular.
And then, to
make them private, which is done...that's turning
a headache into a nightmare.
Can you give me an example of a private snippet or a private template and
how you would use one?
Yeah, as long as you work at the source-level, there is no problem.
But that, in-and-of itself, is the problem. As you
suggest, some, as yet unilluminated patterns, would be most helpful.
If I understood what you were trying to do, I could help you with patterns.
Code works best for me. If you could put together templates and stubbed
Scala and make clear what you're trying to do and what Lift is not letting
you do, I could help you out.
Thanks,
David

Putting code such as this, instead, in your init function helps, but

What particular problem?

[Lift] Re: Scope issues with CometActors
lift:comet type=YourCometClass name={person_number} /
The optional name attribute allows you to have different comet actor names
(e.g., one per person). You can retrieve the CometActor's name via the name
method, which returns a Box[String].
In your CometActor, make sure to:
override def lifespan = Full(5 minutes)
This will make the particular CometActor go away if it does not appear on a
page for a 5 minute span.
This lets you have a different CometActor per person, but allows you to
share a single CometActor instance for a given session for a given name
across browser windows/tabs.
I hope this helps and I'd suggest against using SessionVars for passing
setup information to CometActors.

Naftoli has provided a possible solution but seems more involved than
I have the experience for.
I will resort to putting the stuff on the generated classes and let
merge tools do the rest.
Regarding sharing the codeI should be more specific in that it

Please note it is very specific to my needs (i.e. only

all I needed to process at the time) but is written in a way that
could be extended to the full grammar (at least that was my

So... the problem is that objects in Scala are not subclassible. What does
this mean? For example:
trait Foo {
object bar extends AnyRef
}
trait MyFoo extends Foo {
override object bar {
def cantDoIt = sigh
}
}
Back in the Scala 2.5 days, there was some talk about allowing this to
happen, but it never did. So, unfortunately, I can't think of a way for
your sql generator to create a superclass that could be subclassed and have
the effect that you want.

How do you auto-generate them?

I am using Lift 1.0 with the Mapper ORM module from Lift. I am a
newbie to Scala and Lift. I have auto-generated my ORM classes from
a .sql file. Given that these classes are auto-generated I would
prefer not to edit them directly and provide additional functionality
via inheritance.
Say I have the following...
class StatGenerated extends LongKeyedMapper[StatGenerated] with IdPK {
def getSingleton = StatGenerated
object errors extends MappedLong(this)
object hits extends MappedLong(this)
object AB extends MappedLong(this)
}
object StatGenerated extends StatGenerated with LongKeyedMetaMapper
[StatGenerated] {
override def fieldOrder = List(errors, hits)
}
class Statistics extends StatGenerated {
def GetBattingAverage(id : Long) : float = {
val stat = Stat.findByKey(id)
stat.hits/stat.AB
}
}
Now what I would like to do is work with the Statistics class as my
ORM object...
But I believe everything that is ORM related is actually of type
StatGenerated rather than Statistics. i.e. findByKey will return me a
StatGenerated rather than a Statistics class. Is there any clever way
around this that I am missing without either modifying the generated
class or duplicating code?

[Lift] authentication and access control
Lift users, I'm curious what you all are using for user access control (Mapper users excluded). I'm seriously evaluating lift for a project that will use JPA. My full time job uses Spring Security, which while nice in that it stays out of the way, is too clunky for my tastes. I haven't dissected how lift implements it with Mapper, but wanted to ask the group first.

[Lift] Using Lift to build a Web Service and the PUT HTTP method??
I'm trying to use PUT with Lift and it seems to be working, except I can't find the content I put. I'm using jQuery on the front end (a custom front-end) and firebug seems to think the data gets sent. Although it doesn't show me the raw request, it adds a PUT tab that shows the key and value(I couldn't get PUT in jQuery to work without a key/value pair). So where should I look for this data in the req? I've used POST and GET before without problem, but I need to use PUT here. I looked in the body field and in the xml field (it is an xml string being PUT). BTW, I'm using Lift .11 and scala 2.7.2. So anyone doing this? If so where is the PUT data? Oh also should I upgrade Lift? Last time I did (from .9 to .11) it was a lot of work. Alan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

Is this a known bug, or I have done something wrong when I typed ToDo application from tutorial? -- Lift, the simply functional web frameworkhttp://liftweb.net Beginning Scalahttp://www.apress.com/book/view/1430219890 Follow me:http://twitter.com/dpp Git some:http://github.com/dpp -- Lift, the simply functional web frameworkhttp://liftweb.net Beginning Scalahttp://www.apress.com/book/view/1430219890 Follow me:http://twitter.com/dpp Git some:http://github.com/dpp -- Lift, the simply functional web frameworkhttp://liftweb.net Beginning Scalahttp://www.apress.com/book/view/1430219890 Follow me:http://twitter.com/dpp Git some:http://github.com/dpp -- Lift, the simply functional web framework http://liftweb.net Beginning Scala http://www.apress.com/book/view/1430219890 Follow me: http://twitter.com/dpp Git some: http://github.com/dpp --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

I'd suggest that you use
import net.liftweb.util.Helpers._
def streamToString(stream: InputStream) = new
String(readWholeStream(stream), UTF-8)
See if that makes things better.

Here is the code I am using. The exception is happening at line 12, the

The exception is happening alot. Any ideas?
package com.authoritude.snippet
import java.io.{InputStreamReader, BufferedInputStream, BufferedReader,
OutputStreamWriter, InputStream}
object StreamUtil {
def streamToString(stream: InputStream): String = {
val buf = new StringBuilder
val br = new BufferedReader(new InputStreamReader(stream))
var line: String = null
var eof = false
while (! eof) {
line = br.readLine()
if (line == null) eof = true else
buf.append(line).append(\n)
}
buf.toString
}

[Lift] Re: weirdness with stateful snippets and multiple forms on the page
Lift's multi-step wizard support is less than optimal. I'm working with some folks to improve the situation and it's part of the 1.1 roadmap. On Thu, Aug 27, 2009 at 1:40 PM, harryh har...@gmail.com wrote: Are stateful snippets considered a good way to do multi-step wizard like interfaces? They seem like a good fit, but I'm running into 1 annoying problem. I'm seeting things up so in my .html file I have something like this: lift:MyPage.stepOne form=POST // HTML for step 1 /lift:MyPage.stepOne lift:MyPage.stepTwo // HTML for step 2 /lift:MyPage.stepTwo Then in the MyPage StatefulSnippet I return NodeSeq.Empty for 1 step, and actual contents for the other. The only issue is that for the inactive steps HTML like the following gets sent to the browser: form action=/my_page method=postinput name=F110858803410EI0 type=hidden value=true //form Yeah... that's a bug. I'll have a fix committed up in a few. This isn't a huge deal really, but it's kind of annoying. It almost seems like that a lift: element with a form attribute shouldn't generate the form if the snippet function returns NodeSeq.Empty That's defined behavior and it will be that way in just a minute. -harryh -- Lift, the simply functional web framework http://liftweb.net Beginning Scala http://www.apress.com/book/view/1430219890 Follow me: http://twitter.com/dpp Git some: http://github.com/dpp --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.
