[Lift] Re: Locale and languages
Hi Jon, I have a working implementation of this now :-) To give you some background, we have a locale calculator in lift and its default behavior looks at the incoming request headers to asses what locale should be set. Whilst in normal operation this has no affect on your application, it becomes extremely useful when you want to localize based on a whole bunch of parameters. Check out the scala docs for S here: http://scala-tools.org/mvnsites/liftweb/lift-webkit/scaladocs/net/liftweb/http/S$object.html Because java.util.Locale has really neat features for presenting localized country names etc, i just use a something like: S.locale.getDisplayName(S.locale) // = Might return italiano for instance As for the database content - I have a database backed resource bundle subclass that feeds into an LRU cache when lift boots up. The bundle then talks with the LRU cache to return the correct string. Sorry if that doesnt make much sense! If anything is not clear, then just post back and i'll try to me more succinct. Thanks Tim On Mar 2, 4:43 pm, Jon Hancock shellsha...@gmail.com wrote: I am also interested in locale strategies. I would like to build a website which will be in Mandarin and English. The English is mostly for my use as most users will see mandarin. I expect it will be easiest to have most of my decorative info (link names, static info) in the views themselves. The DB content will be what it is (mostly mandarin), no need for multiple copies. I guess I first want to sniff the request (or maybe do a geo query on the IP) and decide if I should serve up EN or CN views and subsequently allow the user to click a preference (English or Chinese link) to override my guesswork and set a cookie for the preference. I do see how I would set the cookie. How to manage two sets of views I do not see. How have others done this with lift? thanks, Jon On Mar 2, 7:59 am, Derek Chen-Becker dchenbec...@gmail.com wrote: That seems reasonable, although IIRC it means that you need two queries to the database to fetch a translation using mapper strictly.

David, I've created a wiki user jhancock. Could you create a page for ruby/rails/merb to lift and give me rights? I will start off by adding notes for environment and setup issues. The getting current docs are great for those already using Java but could use some extra info for those not familiar with the Java toolchain. I have been away from Java for 5 years and things like Maven and how to have a single scala install that allows me to run jetty, use eclipse, and use the scala interpreter all referencing the same target source is something that is not easily put together...expect my next set of google group pepperings to target those issues. After that, I'll start adding notes as I go through a migration from merb. Then I can go further back and add notes from my older rails code. Then after I have quite a few ramblings put together, I can clean it all up. How does that sound?

[Lift] Re: chaining servlets
PPS The reason i want Jersey on the outbound path is that it has pretty nifty support for rendering to XML and other formats. A single Produces annotation at the class level, for example, suffices to cause all the web methods to render according to format specified in the annotation. Oh, and Jersey also autogenerates the WADL description of the service -- which is going to come in handy for other stuff we're doing. On Mon, Mar 2, 2009 at 3:16 PM, Meredith Gregory lgreg.mered...@gmail.comwrote: Tim, et al, Thanks for the many responses. Here's the overall context. i've got a group that has done some significant work building a JRoR site. Now they want to scale. As a part of a midterm strategy to get some reasonable tooling in, we're building Scala-based RESTful APIs. Being an idiot, i want as general a soln as possible. So, here's what i've done. - a plain, vanilla Hibernate reverse engineering strategy will fetch both JPA and simple POJOs - This gets me Scala access to the backend - Now, i want to generate default controller behavior. i've written a Scala program that eats what Hibernate spits out and creates default controller behavior. It uses the Jersey annotations (Produces, Consumes, Path, GET, PUT,...) to control rendering to/from the client of the RESTful API What i want to do now is to interject lift into the mix so that we can allow programmers to specialize the controller behavior in scala/lift code. The reason i've attempted to be fairly generic about all this is that i believe this represents a tool-chain that allows a semi-automated migration path from pick-you-webframework to lift/scala. The idea is that the SQL schema is about 80% of where the rubber meets the road, so that ought to be the place to hoist your app out of some existing solution. This works especially well if you're transition from a JVM soln (JRoR) to a JVM soln.

[Lift] really stupid maven question
Lifted, i've got all the classes i generate making a class to a Model object derived from the nice work that Derek did on the JPA demo. Now, here's the rub. For some reason it's compiling the generated classes before tackling the compilation of the model object. So... the compilation craps out. i've been working around this by generating the classes, compiling the project (without the classes) then moving them into place in the model directory and compiling the project again. What's the pretty way to enforce this sequentialization in maven. i really want these classes compiled *after* the Model.scala file is compiled. i'd like not to say much more than this ordering constraint to maven -- if at all possible.

[Lift] Re: chaining servlets
Greg, I'm very interested in how this works out. I've been looking at Jersey and I really like the annotations, but I have been way too swamped to really play with it with Lift (I've only tried their Hello World app). If you get this working, I'd love to see it. Chas. Meredith Gregory wrote: Tim, et al, Thanks for the many responses. Here's the overall context. i've got a group that has done some significant work building a JRoR site. Now they want to scale. As a part of a midterm strategy to get some reasonable tooling in, we're building Scala-based RESTful APIs. Being an idiot, i want as general a soln as possible. So, here's what i've done. * a plain, vanilla Hibernate reverse engineering strategy will fetch both JPA and simple POJOs o This gets me Scala access to the backend * Now, i want to generate default controller behavior. i've written a Scala program that eats what Hibernate spits out and creates default controller behavior. It uses the Jersey annotations (Produces, Consumes, Path, GET, PUT,...) to control rendering to/from the client of the RESTful API What i want to do now is to interject lift into the mix so that we can allow programmers to specialize the controller behavior in scala/lift code. The reason i've attempted to be fairly generic about all this is that i believe this represents a tool-chain that allows a semi-automated migration path from pick-you-webframework to lift/scala. The idea is that the SQL schema is about 80% of where the rubber meets the road, so that ought to be the place to hoist your app out of some existing solution. This works especially well if you're transition from a JVM soln (JRoR) to a JVM soln.

This chain is formed indirectly via filter mappings. The order of the filters in the chain is the same as the order that filter mappings appear in the web application deployment descriptor. http://java.sun.com/products/servlet/Filters.html The Jersey will handle the request first, then pass it thru to Lift, then back. I of course have not tested this with Jersey and do not know if there are any strange things that can happen.

[Lift] Building new pages in Lift
I think I've figured out how to add new pages to Lift: 1. Create a new HTML file under src/main/webapp/something.html 2. To add this to the sitemap, go to Boot.scala and add this: val entries = Menu(Loc(Home, List(index), Home)) :: Menu(Loc(Test, List(test), Test)) :: User.sitemap My understanding is that :: is the concatenation operator in Scala, and we are creating a new menu item. 3. Restart Jetty. The new page should be added. Eclipse isn't terribly helpful is determining errors. Is there a better IDE? Now my question is - how would I add a new page into a Lift application that I do not want integrated into the sitemap? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: really stupid maven question
FYI, I've split out the ScalaEntityManager stuff into its own project:
http://scala-tools.org/mvnsites-snapshots/scalajpa/
Snapshot version right now mostly because I haven't had time to really test
it and I haven't heard of anyone using it yet. Hopefully this will further
simplify things for people using JPA. Right now most of my time is taken up
working on the book, but once that's done I'll devote more time to improving
JPA support in Scala and Lift. In the meantime, please let me know if you
run into any issues.

Greg,
I'm guessing that you're generated java classes with that commented out
section? You have to ensure that the maven-scala-plugin is run *before* the
java compiler when using mixed-java/scala projects.
Here's the mvn-fu (also shown
herehttp://scala-tools.org/mvnsites/maven-scala-plugin/usage_java.html
):
plugin
groupIdorg.scala-tools/groupId
artifactIdmaven-scala-plugin/artifactId
executions
execution
idscala-compile-first/id
phaseprocess-resources/phase
goals

goalcompile/goal
/goals
/execution
execution
idscala-test-compile/id
phaseprocess-test-resources/phase
goals
goaltestCompile/goal
/goals
/execution
/executions
/plugin
What we're doing is faking the order of execution (as there's a design
flaw in maven 2.0.x that is being fixed in 3.0). See
herehttp://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.htmlfor
the full maven lifecycle. I'm going to list out the goals I see bound
to phases in your build (if you use the above configuration):
process-sources - maven-jaxb-schemagen-plugin : generate (generates
your .java files)
process-resources - {
maven-resources-plugin : copy-resources (moves resources to target
directory)
maven-scala-plugin : compile (Compiles .scala code, passing .java
files to scalac)
}
compile - maven-compiler-plugin : compile (Compiles Java code, including
generated code)
process-test-resources - maven-scala-plugin : testCompile (compiles
.scala code, passing .java files to scalac)
test-compile - maven-compiler-plugin : testCompile (Compiles java testing
code)
test - maven-surefire-plugin : test (Runs junit/other tests)
package - maven-war-plugin : war (Creates your war file)
...
As you can see, this method (although slightly a hack) ensures the proper
ordering of plugins so your build should complete successfully!

Thanks for the response. Sadly, my mvn-fu is novitiate level; so, the pom
is little more than the vanilla pom that comes with a lift archetype. See
