Default format to enter MappedDateTime in text field?

[Todd O'Bryan]

How do I enter a MappedDateTime in the text field created by CRUDify
so that I don't get NULL?

Thanks,
Todd

It uses LiftRules.dateTimeConverter, which is a factory that by default uses net.liftweb.util.DefaultDateTimeConverter, which is defined as follows (references are to methods in net.liftweb.util.TimeHelpers):

object DefaultDateTimeConverter extends DateTimeConverter {

  def formatDateTime(d: Date) = internetDateFormat.format(d)

  def formatDate(d: Date) = dateFormat.format(d)

  /**  Uses Helpers.hourFormat which includes seconds but not time zone */

  def formatTime(d: Date) = hourFormat.format(d)

  

  def parseDateTime(s: String) = tryo { internetDateFormat.parse(s) }

  def parseDate(s: String) = tryo { dateFormat.parse(s) }

  /** Tries Helpers.hourFormat and Helpers.timeFormat */

  def parseTime(s: String) = tryo{hourFormat.parse(s)} or tryo{timeFormat.parse(s)}

}

Here is an example of supplying your own:

    import java.util.Date

    LiftRules.dateTimeConverter.default.set(() => new net.liftweb.util.DateTimeConverter {

      def dateTime = {

        val sdf = new java.text.SimpleDateFormat("M/d/yy hh:mm a")

        sdf.setTimeZone(java.util.TimeZone.getTimeZone("America/New_York"))

        sdf.setLenient(true)

        sdf

      }

      def date = {

        val sdf = new java.text.SimpleDateFormat("MM/dd/yyyy")

        sdf.setTimeZone(java.util.TimeZone.getTimeZone("America/New_York"))

        sdf.setLenient(true)

        sdf

      }

      def formatDateTime(d: Date) = dateTime.format(d)

      def formatDate(d: Date) = date.format(d)

      def formatTime(d: Date) = DefaultDateTimeConverter.formatTime(d)

      def parseDateTime(s: String) = Helpers.tryo { dateTime.parse(s) }

      def parseDate(s: String) = Helpers.tryo { date.parse(s) }

      def parseTime(s: String) = DefaultDateTimeConverter.parseTime(s)

    })

Thanks for taking the time to answer that. I eventually got through
the code and found my answer and should have posted back when I did.
(I had to print out a date so I could tell what it was looking for.)

Naftoli,

Thanks for replying with this. I thought I had the same issue except
with Record (DateTimeField). I see now how it's not implemented the
same way (not using LiftRules.dateTimeConverter). Should it be changed
to be consistent? Right now I don't see how Record and DateTimeField
are customizable in the same way. Am I missing something? Perhaps
TimeHelpers needs to be aware of LiftRules.dateTimeConverter?

Thanks,

Steve

I would assume it should, although I haven't really used Record and so can't really comment.
