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] Re: QueryParams and joins
Lift uses the SQL IN statement rather than joins. This has a negative
impact for users of MySQL and Derby.
Try:
TagUser.findAll(By(TagUser.tag, this), In(TagUser.user, User.id,
OrderBy(User.followers_count, Descending), MaxRows[User](10)))

But im concerned that this creates an instance for each of the users
in tag tag even though i only need the top x.

Hello, I'm having a problem and I'm sure it's an easy fix for someone
with a bit more experience
I have 3 model classes: tag, user, tweet and a join class TagUser. A
tag has a list of users.
If i want all of the users in a tag i use the following code (which
works):
def users = TagUser.findAll(By(TagUser.tag, this.id)).map
(_.user.obj.open_!)
my problem is that i can't figure out how to apply queryparams so i
don't pull out all of the users from the DB if i don't need em. I was
thinking something like this (doesn't compile):
def getTopUsers(in: Int) :List[User] = {
TagUser.findAll(By(TagUser.tag, this.id),
OrderBy(User.followers_count, Descending),
MaxRows(in))
There is an issue:
OrderBy(User., Descending) // illegal... you can only order by a
TagUser.xxx field
And a potential issue:
MaxRows[TagUser](in) // sometimes the Type Inferencer doesn't get it
right.
What's your ultimate goal?
}
I get the following error:

Ah hah!
I'd strongly recommend you upgrade to Lift 1.1-M8. It's faster, more stable
and better supported than 1.0.

Re: [Lift] Re: QueryParams and joins
It looks like you probably have some other dependencies somewhere or old jars pointing to the old lift version. Please first try mvn clean jetty:run, and if that doesn't work, run mvn dependency:tree to try and find where the other version of lift- webkit is coming from. If you're still stuck, paste the output of dependency:tree please! -Ross On Jan 5, 2010, at 4:06 PM, Mads Hartmann wrote: I really appreciate you taking the time to help me out. depedency now is: dependency groupIdnet.liftweb/groupId artifactIdlift-core/artifactId version1.1-M8/version /dependency It compiles just fine, but when i try to start the server i get the following error: ERROR - Failed to Boot java.lang.NoClassDefFoundError: net/liftweb/util/Box at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:169) at net.liftweb.http.DefaultBootstrap$.boot(LiftRules.scala:1260) at net.liftweb.http.provider.HTTPProvider$class.bootLift (HTTPProvider.scala:70) at net.liftweb.http.LiftFilter.bootLift(LiftServlet.scala:523) at net.liftweb.http.provider.servlet.ServletFilterProvider$class.init (ServletFilterProvider.scala:20) at net.liftweb.http.LiftFilter.init(LiftServlet.scala:523) at org.mortbay.jetty.servlet.FilterHolder.doStart(FilterHolder.java: 97) at org.mortbay.component.AbstractLifeCycle.start (AbstractLifeCycle.java:50) at org.mortbay.jetty.servlet.ServletHandler.initialize (ServletHandler.java:662) at org.mortbay.jetty.servlet.Context.startContext(Context.java:140) at org.mortbay.jetty.webapp.WebAppContext.startContext (WebAppContext.java:1250) at org.mortbay.jetty.handler.ContextHandler.doStart (ContextHandler.java:517) at org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java: 467) at org.mortbay.jetty.plugin.Jetty6PluginWebAppContext.doStart (Jetty6PluginWebAppContext.java:115) at org.mortbay.component.AbstractLifeCycle.start (AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerCollection.doStart (HandlerCollection.java:152) at org.mortbay.jetty.handler.ContextHandlerCollection.doStart (ContextHandlerCollection.java:156) at org.mortbay.component.AbstractLifeCycle.start (AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerCollection.doStart (HandlerCollection.java:152) at org.mortbay.component.AbstractLifeCycle.start (AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerWrapper.doStart (HandlerWrapper.java:130) at org.mortbay.jetty.Server.doStart(Server.java:224) at org.mortbay.component.AbstractLifeCycle.start (AbstractLifeCycle.java:50) at org.mortbay.jetty.plugin.Jetty6PluginServer.start (Jetty6PluginServer.java:132) at org.mortbay.jetty.plugin.AbstractJettyMojo.startJetty (AbstractJettyMojo.java:441) at org.mortbay.jetty.plugin.AbstractJettyMojo.execute (AbstractJettyMojo.java:383) at org.mortbay.jetty.plugin.AbstractJettyRunMojo.execute (AbstractJettyRunMojo.java:210) at org.mortbay.jetty.plugin.Jetty6RunMojo.execute(Jetty6RunMojo.java: 184) at org.apache.maven.plugin.DefaultPluginManager.executeMojo (DefaultPluginManager.java:490) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals (DefaultLifecycleExecutor.java:694) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeStandaloneGoal (DefaultLifecycleExecutor.java:569) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal (DefaultLifecycleExecutor.java:539) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures (DefaultLifecycleExecutor.java:387) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments (DefaultLifecycleExecutor.java:348) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute (DefaultLifecycleExecutor.java:180) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:328) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:138) at org.apache.maven.cli.MavenCli.main(MavenCli.java:362) at org.apache.maven.cli.compat.CompatibleMain.main (CompatibleMain.java:60) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java: 315) at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java: 430) at org.codehaus.classworlds.Launcher.main(Launcher.java:375) Caused by: java.lang.ClassNotFoundException: net.liftweb.util.Box
