[Lift] More on bind and preserving attributes
Hi,
I know this has been discussed somewhat at length (e.g. here
http://groups.google.com/group/liftweb/browse_thread/thread/27aed5f45faf759/a261a2dfe0ae7207?lnk=gstq=attributes+bind#a261a2dfe0ae7207)
but I still think the default behaviour of - should be reconsidered if
at all possible. Here's why:
I went through our app fixing small UI annoyances. One is missing tab
index on input fields. I knew this has been working previously.
Template:
olli
label for=email{S.??(email.address)}/label
user:email user:tabindex=1/
/lili
label for=password{S.??(password)} (a
href={lostPasswordPath.mkString(/, /,
)}{S.??(recover.password)}/a)/label
user:password user:tabindex=2/
/li
/ol
Code:
bind(user, loginXhtml,
email - (FocusOnLoad(input type=text name=username id=email
class=text/)),
password - (input type=password class=password id=password
name=password/),
submit - (input type=submit class=submit
value={S.??(log.in)}/))
Note the user:tabindex attribute which used to emit a tabindex attribute
in the HTML (this has been changed cf. the conversation above)
I can now change user:tabindex to tabindex and - to -% and I get the
tabindex parameter emitted. There are a few problems with this:
1) It doesn't work for the email field since it doesn't bind an Elem but
a NodeSeq (so -% wouldn't now where to attach the attributes. You could
attach the attributes to the first elem in the NodeSeq (which would work
here), but this doesn't sound like a nice general solution)
2) I have to change my code if I need to introduce attributes on the
rendered elem (ignore the fact that my template code already contains a
class attr :-)
3) To change the email field, I came up with this which seems rather
verbose, but perhaps there's a better way?
email - {_:NodeSeq =
val n = BindHelpers.currentNode openOr scala.xml.NodeSeq.Empty
(FocusOnLoad(mixinAttributes (input type=text name=username
id=email class=text/)(n).first.asInstanceOf[Elem]))},
Because of 2) I'm tempted to always use -% in bind. I would like UI
info to be editable by our UI guy without having to change code when
introducing new attributes.
But If I use -% always, it might as well be the default mode of
operation :-) But maybe I'm the only person with such needs?
Imo, it boils down to the fact that I frequently need to specify
attributes in the markup code but have to either 1) anticipate this up
front in the binding or 2) Change both markup and code when a change is
introduced.
I'm not sure what the best solution is but to me it looks like the
problem that needs solving is where to attach the attributes specified
in the markup?
Before trying to solve this I'm interested in gauging the possibility of
changing this at all :-)

[Lift] Binding error in Ajax call : how to debug ?

[Lift] Refactoring Round 2
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.

Re: [Lift] More on bind and preserving attributes
I'm not sure if this addresses your points, but I figured I'd throw
out what I've been doing in case it helps.
I don't use -%, but I do use something similar along with another
implicit so I can place the attrs in exactly the right place, and it
automagically combines class and style attributes correctly. Some
example code:
bind(user, loginXhtml,
email - (FocusOnLoad(input type=Text name=username
id=email class=text / %% currentPrefixedAttrs(input)),
...)
The %% is a method on an extension of Elem which knows how to combine
MetaData like %, but properly handles combining style= and class=
attributes. currentPrefixedAttrs is a helper method that collects all
the attributes of the current binding node with a given prefix and
strips the prefix, basically like S.prefixedAttrsToMetaData, but for
the current binding node instead of the current snippet node.
This is fairly brief, does not have the same which Elem problems
that -% might since you specifically annotate where you want the
attributes to go, does not have the problem with class= and style=
attributes.
I think personally that the default behavior of bind is correct and
least surprising, since (at least for me and the applications I have)
it's very common that a single bound tag does not map one to one to a
result elem.
I'm not sure what the general policy on utility-style stuff like this,
but if there's a desire, I can contribute it into the lift codebase.
Here's currentPrefixedAttrs and it's helpers:
object XMLHelpers {
/** Transform all attributes of a element with the given prefix
to unprefixed attributes with the same values, discarding any other
attributes */
def prefixedAttrsToUnprefixed(prefix: String)(attrs: MetaData):
MetaData =
stripPrefixes(attrs.filter(attrsWithPrefix(prefix)))
/** Strip prefixes from prefixed attributes, leaving unprefixed
attributes */
def stripPrefixes(in: MetaData): MetaData = in.foldLeft[MetaData]
(Null) {
(rest, md) = md match {
case pa: PrefixedAttribute = new UnprefixedAttribute
(pa.key, pa.value, rest)
case upa: UnprefixedAttribute = new UnprefixedAttribute
(upa.key, upa.value, rest)
case Null = rest
case x = throw new IllegalArgumentException(Not sure
how to process + x + (of type + x.getClass.getName + ))
}
}
/** A filtering function which matches any prefixed attribute
with a given prefix */
def attrsWithPrefix(pre: String)(md: MetaData): Boolean = md
match {
case pa: PrefixedAttribute if pa.pre == pre = true
case _ = false
}
/** Implicitly convert an Elem to a ElemExtension to enable
additional functionality */
implicit def elemToElemExtension(e: Elem): ElemExtension =
ElemExtension(e)
/** Like {...@link MetaData#update} but instead of overwriting class
and style attributes, the values are combined with an appropriate
format for those attributes. Other attributes are overwrriten per
usual. */

NamespaceBinding): MetaData = {
def notClassNorStyle(md: MetaData) = md.key match { case

Re: [Lift] How to get the servlet context
A way you can get the Servlet context is like this:
LiftRules.context match {
case context: HTTPServletContext = // do something with
context.ctx which is the javax.servlet.ServletContext
case _ = // do something when the context is not a servlet
context, perhaps log an error
}
The reason you need the match is because Lift can run on non-servlet
web containers, so Lift does not guarantee there is a Servlet context
in scope.
Hope that helps,

According to the Servlet spec each webapp has got a private temporary

ServletContext.getTmpDir(). Please take a look at the spec.

LiftRules.context match {
case context: HTTPServletContext = // do something with
context.ctx which is the javax.servlet.ServletContext
case _ = // do something when the context is not a servlet
context, perhaps log an error
}
The reason you need the match is because Lift can run on non-servlet
web containers, so Lift does not guarantee there is a Servlet context
in scope.
Hope that helps,

LS,
After Ross' kind invitation to post any other questions I might have,
I'll start with
this one:
The web application I am developing needs a scratch directory to white
scaled
images to. I first try to use a subdir of /tmp and put a symbolic
link in place to
access that directory from my project's context. However, this got me
an
error message (something about an aliased resource), so after some
searching
around I decided the best way is to create a directory inside WEF-INF
and
access it through getServletContext ().getRealPath (/...).
From the APIdocs I found out that an instance of a ServiceContext is
passed
to HTTPServletContext, but I haven't been able to find if that is the
instance I
need, or how to get an instance of HTTPServletContext...
Note: I am currently able to read/write temporary finds when running
through
mvn getty:run, but I need a solution that still works when I deploy a
war with
an existing jetty server.
Thanks for any hints!

[Lift] Re: Newbie Question: Problems compiling/running examples
Again, thanks for the quick response -- finally got it! Here's what I
did and what ended up being the problem (maybe an obvious one, but
wasn't to me since I'm new to scala/lift):
1. Ran 'git pull' then 'git reset --hard'
2. Ran 'mvn clean install' from liftweb root
3. Several projects built fine, but I got a compile failure building
the examples. The full maven output is listed below.
4. I thought, Hmmm. This build obviously works for the Lift guys.
What is possibly different about their environment? Scala! For
giggles downloaded Scala 2.7.7 and put in my path.
5. Re-ran 'mvn clean install' from the root and everything worked.
So for noobs such as myself, the following things were needed in
addition to Maven:
1. increase the default Maven heap size. This is pretty easy, but I
also use Maven all the time. For someone new to Maven, this might not
be obvious: export MAVEN_OPTS=-Xmx1024m
2. Download Scala 2.7.7 and put it in the path. This is not obvious
because the build sort of works without it (I guess the Maven scala
plugin does the compilation?).
Again, good response time on the help. That is important -- I'm
evaluating Grails, Roo, and Lift as potential options for a project.
I'm a Java dev, so Grails/Roo is easy. I like what I've seen so far
from Lift, but I'll also probably have a lot of dumb questions since
I'm new to scala, so it is important to have a responsive community
and that seems like that's what you've got.

Re: [Lift] Re: how does lift work with redis?
2009/11/27 Jim Barrows jim.barr...@gmail.com 2009/11/26 surfman chinasmile...@gmail.com So, if I want to use nosql database with LIFT, what I have to use is JDBC driver, am I right? Any experienced suggestion? Google has very little searching result on it. I'd appreciate any idea on this topic. Thanks. No, you can use whatever Java driver the nosql database comes with. If the nosql database has a JDBC driver, then you might find it easier to use one of the Java ORM systems that support it. However, JDBC is pretty much a SQL thing, so that might be difficult. Using a nosql database means that you don't have access to some of the built in features that Mapper and Record give you for data mapping, and form generation, but you should still be able to use Lift quite easily. Record is not tied to SQL. One should be able to write a bridge from Record to a NoSQL DB.

RE: [Lift] Re: overriding ConnectionManager.newSuperConnection
Yeah, IIRC what happened was that it was trying to read tables from the schema
with the user's name (assuming it was the default) while when it actually
created them they went into the actual default, PUBLIC. I think this resulted
in Schemifier trying to create tables that existed maybe.
So the real fix was setting the H2 DriverType default schema to PUBLIC, as we
realized only later.

Hi David,
I did work around this by putting the schemas in my search path.
Edit postgresql.conf and add the following:
search_path = '$user,public,schema1,schema2,schemaN'
As for this being a bug... did you intend for Mapper to support
schemas on the CRUD side?
The support for schemas in schemifier was a special-case fix for, if I remember
correctly, something relating to H2 and the way H2 user names are related to
something.
I think the short answer is that we're not going to explicitly support schemas
in Mapper. If you need a more complete ORM, please use JPA.
Sorry.
If so, I'd be happy to create a repro.
BUT it can quite easily be reproduced by taking an existing project
and moving an existing table into a schema:
$ psql yourdb
yourdb=# create schema someschema;
CREATE SCHEMA
yourdb=# alter table user set schema someschema;
ALTER TABLE
Now relaunch your app, and you'll see some issues with the user table.
Previously I had to alter my User companion object like so:
override def dbTableName = someschema.user
...for Mapper to issue the correct queries to the database.

Re: [Lift] Re: How to get the servlet context
Job, This directory is managed by the servlet container and as far as I know there is little you can do to configure the location. If you use Tomcat you are able to specify CATALINA_BASE and it will be somewhere beneath that directory, I believe it is work/Catalina/localhost/WABAPP-NAME.

[Lift] Re: Beef with LiftRules.explicitlyParsedSuffixes
For a default behavior this is a reasonable approach. But from a framework perspective this is a little limiting. In order to be more extensible I think we should allow users to plug in their own splitting functions (say a LiftRules RulesSeq of functions) and essentially determine what is suffix and what is not based on potentially some more complex rules.

Re: [Lift] Re: How to get the servlet context
Here's a nugget of information for you that will help (as I do something similar to what you want in one of my applications): val protectionDomain: ProtectionDomain = classOf[bootstrap.liftweb.Boot].getProtectionDomain() val location: URL = protectionDomain.getCodeSource().getLocation() Print the value of location, and that will get you headed in the right direction ;-) Moreover, if your using jetty, if there is a work directory next to where the war file is, jetty will automatically expand the war into that work folder... if not, it makes a temp directory in the relevant OS temp directory (/var/tmp on *nix OS) Godspeed.

[Lift] Re: fsc and Lift
If you're using Maven to manage your Lift project and especially testing things with the mvn jetty:run target, run mvn scala:cc in another shell. It will run fsc, detect source file changes and recompile them, reloading classes or restarting Jetty as necessary. It works very well, though I find that editing actor classes tends to require a true shutdown of Jetty and restart.
