[Lift] Re: conflicting slf4j versions when using M3 with smile
Hmm, slf4j-log4j12-1.5.11.jar ends up being in the classpath twice (from /Users/harryh/foursquare.web/lib_managed/compile and /Users/harryh/foursquare.web/target/webapp/WEB-INF/lib). A quick fix would be to apply exclusion of slf4j-log4j12 in lift-util declaration. This will prevent having slf4j-log4j12-1.5.11.jar under target/webapp/WEB-INF/lib. Then I don't get slf4j-log4j12 at all and I get exceptions: java.lang.NoClassDefFoundError: org/apache/log4j/Logger at net.liftweb.util.LogBoot$.net$liftweb$util$LogBoot$ $_logger(Log.scala:207) at net.liftweb.util.LogBoot$$anonfun$6.apply(Log.scala:209) at net.liftweb.util.LogBoot$$anonfun$6.apply(Log.scala:209) at net.liftweb.util.Log$.rootLogger(Log.scala:85) at net.liftweb.util.Log$.warn(Log.scala:123) at net.liftweb.http.LiftServlet.service(LiftServlet.scala:89) Maybe this is a weird SBT problem? -harryh -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Potential breaking change: MappedField.name, affects Mapper JSON
If this does happen please take care to include this information in
the release notes for M3 (or whatever milestone first has this change)
as people using json serialization for caching purposes will need to
invalidate their caches.
Putting the note in BIG CAPITAL LETTERS might be a good idea.

Hi,
As part of
fixinghttps://www.assembla.com/spaces/liftweb/tickets/155-lift-mapper-%28re...
, I would like to change the semantics of MappedField.name slightly:
Currently, the name is always lowercased, ie:
class SampleModel extends KeyedMapper[Long, SampleModel] {
object id extends MappedLongIndex(this)
object firstName extends MappedString(this, 32)
object moose extends MappedNullableLong(this)
object notNull extends MappedString(this, 32)
}
firstName.name == firstname notNull.name == notnull id.name==id
I would like to have name preserve the case of the field such that:
firstName.name == firstName notNull.name == notNull id.name==id
Reasons:
1) More consistent. css styles, default column headers etc based on name now
follows the actual
field name
2) Easier to implement #155 :-)
name is used when serializing a Mapped object as JSON. So the JSON
representation will be changed (unless we lowercase the name only when
creating JSON, but this goes against 1)
Now:
{
$persisted:true,
id:1,
firstname:Elwood,
moose:null,
notnull:
}
After proposed change:
{
$persisted:true,
id:1,
firstName:Elwood,
moose:null,
notNull:
}
I would like to get a feel for the pain this will cause people

[Lift] Re: lifecycle callbacks in record
OK kids. Here's a lesson for you. Don't mix Mapper and Record in the
same file! Cause if you do, you might do something like this:
class MCheckin extends MongoRecord[MCheckin] with MongoId[MCheckin]
with LifecycleCallbacks {
}
and wonder why the #$%^*( the callbacks aren't being called. But
then, after 5 hours of tinkering you finally realize that you were
implementing the mapper LifecycleCallbacks and not the record
LifecycleCallbacks.

[Lift] Re: Breaking changes in lift-record 2.0-SNAPSHOT - Optional fields
What is the advantage of doing it this way as opposed to having a
collection of Field types who's value is a Box[Whatever]
(OptionalStringField, OptionalLongField, etc).
I'm finding the e-mail you sent to the list moderately confusing.
Maybe it's just that more explanation is needed?
-harryh
On Feb 11, 11:49 pm, Ross Mellgren dri...@gmail.com wrote:
I just committed a change to lift-record in 2.0-SNAPSHOT that will possibly
(probably?) break your build if you use it.
This change makes it possible to have any record field be optional -- that
is, Box[MyType]. You use it like this:
object MyRecord extends Record[MyRecord] {
object myNormalField extends StringField(this, 100)
object myOptionalField extends StringField(this, 100) {
override def optional_? = true
override def defaultValueBox = Empty
override def defaultValue = nothin
}
}
val r: MyRecord
r.myNormalField.set(Hello) // as before the change
r.myOptionalField.setBox(Empty)
r.myNormalField.value == Hello // as before
r.myNormalField.valueBox == Full(Hello)
r.myOptionalField.valueBox == Empty
r.myOptionalField.value == nothin // because defaultValue was used to give
back something
As part of this change, the semantics for field errors has changed somewhat
-- hopefully, to be more consistent.
Previously if you tried to set a field and checkCanWrite_? returned false
then an internal flag valueCouldNotBeSet on the field will be raised which
makes that field generate a validation error when validate is called on the
record. In addition, some fields (but not all) would raise the same flag and
return Failure or Empty from setFromString or setFromAny upon being given an
invalid value.
With this change, all types of failure to set now result in the field value
becoming a Failure. setFromAny, setFromString, and setBox all return that
Failure, while set will return defaultValue (due to its return type.)
validators and set filters have had their types changed to Boxed equivalents.
And finally, I made consistent the setFromAny methods of all the built-in
field types so that they all follow the same contract. For setFromAny it's
essentially accept one of MyType, Box[MyType], Option[MyType], or
List[MyType] as well as null, with a default to convert an unknown input to
string and use setFromString. For setFromString, it is as before, except if
the field is optional_? and the empty string is passed in, that's treated as
Empty.
As I'll mention in another message, I also pushed lift-couchdb to master. I
ran the unit tests that I wrote for that, but that doesn't give me full
confidence that all the fields are entirely bug free. Similarly I did not
test the form generation. If anybody runs into any issues please let me know
and I'll fix it as soon as I can. And of course if it causes too much
breakage we can revert it back out.

[Lift] Re: Sharing data between snippet functions during a single HTTP request
Another strategy, different from what Ross suggests, that I have found
useful in some circumstances. In the view do this:
lift:YourPage
page:firstsection
firstsection:username/
firstsection:foo/
/page:firstsection
page:secondsection
secondsection:username/
secondsection:foo/
/page:secondsection
/lift:YourPage
Then
class YourPage extends RenderSnippet {
def render(xhtml: NodeSeq) = {
val user = User.currentUser
def firstSection(xhtml: NodeSeq) = {
val foo = whatever
bind(firstsection, xhtml, username - user.name, foo -
foo.name)
}
def secondSection(xhtml: NodeSeq) = {
val bar = whatever
bind(firstsection, xhtml, username - user.name, bar -
bar.name)
}
bind(page, xhtml, firstsection - firstSection _,
secondSection - secondSection)
}
}

Yes, what Ross said. Further, taking a look at JsonParser.scala the
bug appears to be on line ~202 where there are a couple of missing
escape sequences: \/ as well as \f.

[Lift] Re: simple database question
Here is what you need for a minimal Person table that contains two
columns: an id for the primary key, and name which is a string:
package com.jacksdomain.model
import net.liftweb.mapper._
class Person extends LongKeyedMapper[Person] with IdPK {
def getSingleton = Person
object name extends MappedString(this, 100)
}
object Person extends Person with LongKeyedMetaMapper[Person] {
override def dbTableName = person
}
You can then do things like this:
val person = Person.find(1) // retrieve the person with id = 1 from
the database
val person = Person.find(By(Person.name, Jack)) // retrieve the
person with name = Jack from the database
val people = Person.findAll() // retrieve all people form the database
val people = Person.findAll(By_(Person.id, 10)) // retrieve all the
people with id 10
etc.

[Lift] lift-json question related to Lists of things
consider:
case class Foo(id: Int, bars: List[Bar])
case class Bar(id: Int)
val foo = json.extract[Foo]
The following json will cause a problem:
{
id: 12
}
This can be fixed by changing bars to an Option[List[Bar]]. Should
that really be necessary though? Can't bars just be an empty list if
there are none of them?

[Lift] Memcached + Mapper (or Record?)
Is anyone successfully running Lift with a simple Memcached based row cache? If so, are you doing it with Mapper or Record? Are there any docs and/or sample code that would help with this sort of thing? I'm happy to read source code, but wondering if there are any other resources in this general area that might be useful. -harryh -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Memcached + Mapper (or Record?)
Then how to go back from the case class (pulled in from memcached) to a Mapper object (that I can modify and then save)? I'm worried about getting the mapper object in an incorrect state where it thinks it needs to add a new row to the table on save rather than update an existing one. Ideally I'd like to override findDbByKey() in my MetaMapper class, and save() in my Mapper class(1) and leave the rest of my code unchanged. -harryh (1) And maybe also bulkDelete_!! and delete, but you get the general idea. Personally, I'd use final case classes, serialize them via lift-json and put them in memcached... but that's just me. -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Memcached + Mapper (or Record?)
Hmmm... so you want to cache the model object in memcached rather than keeping a link to it in the JVM. Yes, because I'm running on 1 JVMs. when you have a modify operation to the model object, you want to update the field and hit save and have the right row go back to the RDBMS? Yes. Where the object was originally loaded from memcached or the RDBMS (if it wasn't in the cache). Further, the save should update the cache as well as the RDBMS. (sorry if I'm being dense... just want to create a firm picture in my head of what you want to do.) No problem at all. And definitely tell me if what I want to do sounds crazy to you for some reason. Ultimately what I want to do is decrease the load on my RDBMS. How I go about that exactly is all up for discussion. -harryh -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] intro to lift-json?
Is there a basic intro to lift-json floating around anywhere? I'm
having a bit of trouble getting started with a couple basic things.
For example if a have a JObject that corresponds to:
{
foo : {
bar : 999
}
}
How do I get the 999 (as an int) out of the JObject? I'm sure this is
simple, just a bit confused on the basics.

[Lift] foursquare.com now basically all on Lift
I've been a bit coy about it on the list, but three months ago when I joined the team at foursquare.com I made the final decision that we would port our webservers to Scala/Lift.

REST api (api.foursquare.com). I'd like the send a huge thank you to dpp and the rest of the Lift team. You've built a really great framework here, and I look forward to using it and seeing it grow for many years to come. An additional thanks goes out to all those who have answered my many random questions over the past couple of months. For those who haven't yet found out about foursquare, you can read more about it here: http://foursquare.com/learn_more Anyways, that's about enough self promotion, but I did want to officially let the community know about what I hope will be a fairly high profile site that is using Lift. -harryh (1) Haven't quite ported feeds.foursquare.com, and there is a legacy PHP based REST api that will live on for a bit longer as it supports current versions of our iPhone app. -- You received this message because you are subscribed to the Google Groups Lift group.

The problem is that emtyMap in the second RewriteResponse. The

being destroyed at which point bad things happen.
Is there a better way to do what I am trying to do here?

[Lift] Re: maintaining logged in user longer outside of SessionVar
It's going to load the user for each stateful request. What do you mean by a stateful request? I guess we can change it up to make the load lazy so it'll only happen in the requestvar is actually accessed. Does that sould reasonable? If that makes it so I don't hit the database when loading static files, then yes. -harryh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] maintaining logged in user longer outside of SessionVar
I want users to stay logged into my site for extended periods of time (through server restarts, and browser restarts). By default Lift stores a User in a SessionVar so this doesn't get me there. I've configured jetty so the session cookie doesn't time out for 30 days, and I have a database table with a session id - user id mapping, but keeping this up to date has proven to be kind of a pain as the session id can change from time to time (like when I restart my servers to push a new website version) and it's a bit more tricky than I would like to handle all of this correctly. Are any other lift users trying to accomplish the same goal? How have you gone about it? Would it be a good feature for the framework to have something to do this a bit more built in? -harryh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

This seems very strange to me, and I don't have a minimal test case yet, but I'm seeing a problem where elements are not being properly bound when they appear inside of a select in my view. So, for example: select stats:options /select stats:options isn't being bound. But div stats:options /div gets bound find (but then I, obviously, don't have proper HTML since the options are inside of a div instead of a select). Has anyone else seen this?

So, your callOnAjaxCompleteFunc will be called if any of the ajax functions in the block are executed. That's certainly one way to go. I was thinking it might be nice to modify the URL used for the ajax request though because then the request can be logged in a standard way (whatever it is that jetty/ tomcat/whatever server you are using is already doing) and parsed with standard tools. callOnAjaxCompleteFunc could certainly create a log entry designed to look like the above, but it might be a bit more work for the developer. -harryh PS: Just so you know this isn't high priority or anything.

[Lift] LongKeyedMapper object where I can set the id
LongKeyedMapper object where I can set the id.
I want a database object where I set the primary key myself (rather
than having it be sequentially by the database). I thought I could do
this:
class Tombstone extends LongKeyedMapper[Tombstone] {
def getSingleton = Tombstone
def primaryKeyField = id
object id extends MappedLongIndex(this) {
override def writePermission_? = true
}
}
object Tombstone extends Tombstone with LongKeyedMetaMapper[Tombstone]
{
override def dbTableName = tombstones
}
But when I do Tombstone.create.id(12).save it does an UPDATE instead
of an INSERT. Is there any good way to do what I want here?

- Would also be nice if all excessive white space were stripped from the output (not sure how much this matters if it's gzip'ed) This would be nice as well, but can be a lot more complicated. GXP (a templating language I worked on at Google) had pretty awesome whitespace control that I'm happy to describe in detail if dpp (or another committer) is interested.

Personally, when doing this, I like splitting out the code to fill in
the rows into a separate function like so:

})
}
bind(questions, xhtml, row - row _)

tdquestion:id//td
tdquestion:text//td
tdquestion:answers//td

The result should be a table row like that:
tr id=someId
td.../td

/tr
So in this case I want to replace the row-element itself (and add an
attribute value), but the contents (children) of the row-element must be
preserved! How can this be accomplished?
Thank you!

~1125 ms for your query. ~50ms for the IN based on that lift currently generates. This is doing things in the psql console on the same machine the database lives on. It's not so much the query time that concerns me, as the amount of data being sent back in the results. In my example at the top of the thread I only need 10 users, but the query is spitting back thousands. -harryh On Sep 10, 2:16 pm, Viktor Klang viktor.kl...@gmail.com wrote: On Thu, Sep 10, 2009 at 8:15 PM, Viktor Klang viktor.kl...@gmail.comwrote: On Thu, Sep 10, 2009 at 6:23 PM, harryh har...@gmail.com wrote: Consider: val venues = Venue.findAll(By(Venue.cityid, City.currentCity), NotNullRef(Venue.owner), OrderBy(Venue.id, Descending), MaxRows(10), PreCache(Venue.owner)) This appears to be generating a query like so: SELECT DISTINCT users.id, users.firstname, users.lastname FROM users WHERE id IN (SELECT owner FROM venues WHERE cityid = 22 AND owner IS NOT NULL ) - 970ms Just out of curosity, if you run the following query, how long does it take?
