No this isn't what I'm suggesting, I don't think MappedEnum should be made
flexible.
I was thinking perhaps your class could work with EnumWithDescription as
shown below, which
extends Enumeration#Values to include a description.

/*
 A wrapper arround a Scala Enumeration Value that has a name, description
for each object
 */
trait ValueWithDescription  {
def description: String
def name: String
}

abstract class EnumWithDescription  {
type Value = enum.Value with ValueWithDescription

private var _values: List[Value] = Nil
def values = _values

// possibly not a good idea using this directly
val enum = new Enumeration {
def Value(inName: String, inDescription: String): Value with
ValueWithDescription = {
new Val(nextId, inName) with ValueWithDescription {
def description = inDescription
def name = inName
}
}
}

def Value(name: String, description: String): Value = {
val value = enum.Value(name, description)
_values = _values ::: List(value)  // build in order
value
}

def Value(name: String): Value = Value(name, name)

def valueOf(name: String) = values find (_.name == name)

def nameDescriptionList = values map(x => (x.name, x.description) )

}

Naftoli, you would overload the _editTemplate field or the

[Lift] form element specific error messages

[Trav]

I have a form such as:


  
  
  


and a bind:

bind("newCustomer", xhtml,
   "firstName" -> text(XXX),
   "lastName" -> text(XXX),
   "submit" -> submit(XXX)
)


If I want to require that both first and last name are required, but
the form is submitted with no last name, how anyone suggest that I put
the error message "*Required" in the appropriate div tag next to the
text box.

[Marc Boschma]

Sleeping on it the snippet would be as simple as

def group(c : scala.xml.NodeSeq) : scala.xml.NodeSeq =  
scala.xml.Group(c)

which would allow for:


Welcome
Put welcome details here


The advantage is that it is in the lift name space...

The MySQL driver may have facilities for connection pooling, but generally
you use a pool provider (dbcp, c3po, etc) or write your own.

[Lift] Re: JPA and auto generation of id

I've used JPA with MySQL in the past and I don't recall having to specify a

particular entity have AUTO_INCREMENT set for the id column?

This is a known issue - I'll get round to rebuilding the site soon (it was

eliminate these kinds of bugs.

[Lift] MySQL connection pool

[ph]

It's not strictly Lift question...

Is connection pool a feature of MySQL JDBC driver? It is a feature of
MySQL ODBC driver...
Looking into this article
http://dev.mysql.com/tech-resources/articles/connection_pooling_with_connectorj.html
it's not clear to me wheather connection pool is implemented in
application server or in driver itself.
I'm planning on writing own application server and don't know if I
need to worry about implementing connection pooling or not.

[Lift] From JPA question to ScalaQuery to Collection Abstractions

[Meredith Gregory]

All,

Again -- many thanks to the posters and responders on this thread. i've
moved on to attempt to use
ScalaQueryas the
target for the SQL persistence. Stefan Szeiger describes his work
here
.

It seems to be a week of meeting resistance, however. i've been attempting
to build the simplest possible collection to use as a toy to test my
compilation strategy. This has turned out to be quite a little brain-teaser.

For me simpler means: contains less information. In this sense, a Set is
simpler than a List. The simplest possible collection i can imagine (that
still supports associativity -- and i don't know if i can call something
that doesn't support associativity a collection) is a monad. A monad doesn't
commit to what the collection contains; only parametrically commits to how
to put things into the collection; and only parametrically commits to how to
flatten the collection (which is tantamount to supporting associativity).

After thinking about it for half a day, and revisiting the
Moors-Piessens-Odersky (MPO) paper on higher-kinded types, i realized that
the MPO construction doesn't actually apply to Scala in practice (someone
please tell me if i'm wrong) because they fundamentally rely on
constructions using type *members* and not type *parameters*. Unfortunately,
most of the collections libraries are written using type parameters. So, i
decided to roll my own and see what i got.

Here's what i came up with last night.

// smallest expression of monad i can find
trait MBrace[C[_] <: MBrace[C,A],A] {
  def nest( a : A ) : C[A]
  def flatten[T <: C[C[A]]]( bsq : T ) : C[A]
}

// one of the simplest witnesses of monad i can find
class MBraceSeq[A]( a_ : A* ) extends Seq[A] with MBrace[MBraceSeq,A] {
  override def nest( a : A ) = new MBraceSeq[A]( a )
  override def flatten[T <: MBraceSeq[MBraceSeq[A]]]( bsq : T ) :
MBraceSeq[A] = {
(new MBraceSeq[A]( ) /: bsq)( {
  ( acc : MBraceSeq[A], e : MBraceSeq[A] ) => ( acc ++ e
).asInstanceOf[MBraceSeq[A]]
} )
  }
  override def length = a_.length
  override def elements = a_.elements
  override def apply( n : Int ) = a_.apply( n )
}

i was mostly ok with this -- apart from some desiderata/concerns regarding
the Seq methods being visible at this level. i woke up this am and realized
that this is not even wrong. It requires an instance of MBrace to invoke the
nest or flatten methods.

Geez, i feel like a first year undergrad. All i want to do is write the
simplest possible collection on which i can then test a persistence
strategry and i run into roadblocks everywhere. ;-)

Best wishes,

--greg

[Lift] Re: date management

[TylerWeir]

The code Derek included:
// Set the up the RequstVar to initialize a new MyUserClass by default
object userVar extends RequestVar[MyUserClass](MyUserClass.create)

By default creates a MyUserClass instance.
Maybe you want to init the RequestVar as an Empty Box and then
conditionally modify it.

object userVar extends RequestVar[Box[MyUserClass]](Empty)

Then after you save, you can set the RequestVar to Empty again.

Without looking at your code, this is a guess, I could be/probably am
wrong.

[Lift] Re: New mapper class: MappedEnumString

Good question :-) I'm still using CRUDify generated views while
prototyping, but will probably need some more sophisticated layouts at
some point. Don't yet know if the display value will come from the
mapper object or the underlying enum.

Sure. It might also be possible to make the original MappedEnum a bit
more flexible instead (as Derek suggested earlier). My class is
basically just a copy with very few modifications to handle the db
value. I just haven't got the Scala knowledge yet to easily see how
the interface should be and I needed to nail the db schema :-)

I need this as well, especially since there are some patches that
provides pie charts

Yeah, this would be nice :-) We probably need some working code within
the next few weeks so probably can't wait for 2.8 though.

What's the best way to coordinate this? Just fork the code on github or?

OK, just ignore this message, it was a *Scala* presentation, not a
*Lift* one - sorry, I read your post too quickly - and no, the fact
that we were in Lift ml didn't make me find that strange :)

I did a presentation some weeks ago, the slides are under a creative 
common licence, so use them if you want !

[Lift] Re: Getting Username and Password from URL of form hxxp://user:passw...@foo.org

[Timothy Perrett]

Are you using the builtin support for basic authentication in lift? If
not, please see my example here: http://is.gd/1cYhR

The format you mention is standard HTTP Basic, and in accordance with
the RFC's - it should be Base64 encoded. Lift supports both HTTP basic
and HTTP digest.

Cheers, Tim
