Hey folks,
Just released lift-formality 1.0.0. It's got a lot of tidbits to it; see the release
announcement for more. Most importantly, we're now using it in production
at Elemica, so as we run into issues we'll be addressing them.
Currently it's only for Lift 2.6 and Scala 2.11, but I'll be working to fix that
hopefully by the end of the year.
I'll drop a slightly simplified version of the first form that Ari built using lift-formality
here for fun:
val processingMode =
selectField[ProcessingMode](
".upload-processing-mode",
processingModes,
asRadioButtons = true
) ? { mode: Box[ProcessingMode] =>
mode match {
case Full(_) => Empty
case _ => Full(S ? "validation.notEmpty")
}
}
val connectionGroup = field[String]("#connection-configuration-value") ? notEmpty
val uploadedFileField = fileUploadField("#message-file-upload")
val pastedTextField = field[String]("#paste-message")
val inboundConfigurationIdGroup =
fieldGroup(".inbound-configuration").withFields(
processingMode,
connectionGroup
).withBoxedConverter { (processingMode: Box[ProcessingMode], connectionGroupId: Box[String]) =>
for {
mode <- processingMode
connectionGroupId <- connectionGroupId
connectionGroup <- ConnectionGroup.get(connectionGroupId)
inboundGroup <- connectionGroup.inboundConnectionModeGroup
configurationId <- Box(inboundGroup.getConfigurationIdForProcessingMode(mode)) ?~ (S ? "messageSubmission-configurationNotAvailableForMode") ~> "inbound-configuration"
} yield {
configurationId
}
}
val messageContentGroup =
fieldGroup(".upload-message-container").withFields(
uploadedFileField,
pastedTextField
).withBoxedConverter { (file: Box[FileParamHolder], text: Box[String]) =>
val textBytes = text.filter(! _.isEmpty).map(_.getBytes(Charsets.UTF_8))
val fileBytes = file.map(_.file)
textBytes or fileBytes match {
case empty: EmptyBox =>
S.error("upload-message-container", S ? "submitMessageModal-mustHaveEitherFileOrMessage")
Empty
case bytes =>
bytes
}
}
val messageSubmissionForm =
form withAjaxFields(
inboundConfigurationIdGroup,
messageContentGroup
) onSuccess { (inboundConfigurationId, messageContent) =>
handleSubmitResult(submitMessage(inboundConfigurationId, messageContent))
MessageProcessed
}
"form" #> messageSubmissionForm.binder
Enjoy!
Thanks,
Antonio

I'm really excited about how this can be used to not only clean up form creation, but it can make dumb forms and ajax forms use the same code. This will be solid when combined with the VDOM stuff.

Just need to figure out the display of validation errors for “dumb” forms. Still
thinking about that one in the back of my head... There's some potential complications
there for sure.
Should be able to cook something up though ;)
Thanks,
Antonio

Oh yeah!
That relatively-small snippet does quiiiiite a bit too... POWAH!
Kudos to ya for busting it out - especially those boxed converter bits that proved oh so handy :)
