Howdy.
I’ve got an overridden to_xml() function in one of my models that
appears to be very slow. As a relative Ruby novice, I would love to
hear suggestions on how to improve the performance. Incidentally, I
was using the default to_xml() provided by ActiveRecord, but it wasn’t
handling null data the way I wanted.
class Errors < ActiveRecord:Base
…
def to_xml(options = {})
options[:indent] ||= 2
xml = options[:builder] ||= Builder::XmlMarkup.new(:indent =>
options[:indent])
xml.instruct! unless options[:skip_instruct]
xml.error do |x|
x.id(self.id) if self.attributes.has_key?

x.crtd(self.crtd.strftime("%Y-%m-%d")) # Why wouldn’t this
have worked?..
perhaps it should have been crtd.to_date.strftime() …
x.schd(self.schd.strftime("%Y-%m-%d"))
x.crtd(self.crtd ? self.crtd.to_date.to_s(:db) : "")
