I have no idea how to fix the code so it deduces the correct type or if I've
diagnosed the problem incorrectly; however, you can force the type:
object testEnum extends JSONEnumNameField[Settings, TestEnum.type](this,
TestEnum)
and that seems to make it happy. I tried this with 2.8.0.Beta1 also and it
appears that it also rejects it.

Re: [Lift] Trouble with lift-couchdb
I'll have to look at this in more detail tonight. I took a quick couple hacks
at it and I can honestly say I have no idea what kind of problem the Scala
compiler is trying to tell you about :-/
If you avoid types, they clearly are of the same type and value (e.g.
settings.testEnum.valueBox.open_! == Full(TestEnum.One) - true)

Ok, thanks for the hint. I clean compiled each Scala library that touches the

of Scala in the path (I checked with the Maven dependency plugin, and I do not
get the warning that multiple versions were detected) but I am still seeing the
error. Anything else I should try in order to eliminate library/compile
versions as the culprit?

Re: [Lift] Trouble with lift-couchdb
To test further, I've created a simple test project with only one dependency,
lift-couchdb, and this code:
object Settings extends Settings with CouchMetaRecord[ Settings]
class Settings extends CouchRecord[ Settings] {
def meta = Settings
object updated extends JSONDateTimeField( this)
}
object Testing {
def main( args: Array[ String]) {
import CouchDB.defaultDatabase
defaultDatabase = new Database( :/( localhost, 5984) as_! (
username, password), database)
val settings = Settings.createRecord
settings.updated( Calendar.getInstance( TimeZone.getTimeZone(
UTC)))
settings.save
}
}
I get the same error:
java.lang.AbstractMethodError:

I've also put the test code in Github in case anyone might be able to reproduce
it locally:

If JSONRecord generates a runtime AbstractMethodError, compiling it with the
same classpath would generate a compiler error.
Do you know what that test.Settings... line is referring to? If not look up the
line mentioned. Something about that reference is different between compile
time and runtime.

Ok, thanks for the hint. I clean compiled each Scala library that touches the
project (including lift), and made sure that their are no conflicting versions
of Scala in the path (I checked with the Maven dependency plugin, and I do not
get the warning that multiple versions were detected) but I am still seeing the
error. Anything else I should try in order to eliminate library/compile
versions as the culprit?

Okay, type erasure ate your lunch. I have a patched version locally that
apparently works -- your code on my machine gets to invalid username or
password accessing Couch, which indicates it got past the previous problem.
I'd love it if you could apply this patch to your local trunk and give it a
quick spin. If it works out for you, I'll get it into master, along with that
new enum field.

Unfortunately the compiler error is bizarre (due to some of the type shuffling
involved), but the underlying problem you're experiencing is that
DateTimeFields (and therefore JSONDateTimeFields) have a storage type of
Calendar, and you're trying to assign a Date to them. Try Calendar.getInstance
instead of new Date() and see if that resolves it for you?

Re: [Lift] Trouble with lift-couchdb
Sure, will do. The only thing I think I'll need to figure out is how to
persist an enumeration by name rather than ordinal value, but I imagine that it
should be pretty straight-forward to add a new field type in my app to handle
it.

Let me know if it works for you. If so, I'll start the process of getting it
into master as soon as I can.

that DateTimeFields (and therefore JSONDateTimeFields) have a storage type
of Calendar, and you're trying to assign a Date to them. Try
Calendar.getInstance instead of new Date() and see if that resolves it for
you?

Hi,
I am getting familiar with the lift-couchdb module, and trying to put
together a sample based on the tests in the module. Trying to create a
record, based on this test code:
def testRec1: Person = Person.createRecord.name(Alice).age(25)
this is what I have:
class Account extends CouchRecord[Account] {
def meta = Account
object created extends JSONDateTimeField(this)
}
object Account extends Account with CouchMetaRecord[Account]
...
val account = Account.createRecord.created(new Date())
I get a compilation error:
[WARNING] Test.scala:44: error: overloaded method value apply with

forSome { val _13: object test.Account#created } cannot be applied to
(java.util.Date)
[WARNING] val account = Account.createRecord.created( new

I'm sure that I am just missing something obvious. Any ideas what?
Thanks,

Re: [Lift] Trouble with lift-couchdb
Just took a minor change to compile (didn't like ?~) and I'll let you know how
it goes soon. I'm running into one more problem, this time a runtime exception
saving a document:
java.lang.AbstractMethodError:
test.Settings$updated$.encode(Ljava/lang/Object;)Ljava/lang/String;

at net.liftweb.common.Full.map(Box.scala:330)

The field is defined as:
object updated extends JSONDateTimeField( this)
Surely something else I missed?

Re: [Lift] Trouble with lift-couchdb
AbstractMethodError means you need to do a clean build and make sure you don't
have multiple scala versions.
