that should be the encoding of a single Errors instance.
xml.error do |x|
x.id(self.id)
x.msg(self.msg)
x.error_date(self.error_date.strftime('%Y-%m-%d'))
end
I think that you'd get a bunch of errors with:
Errors.find(:all, :conditions => [...]).to_xml(:root => 'errors')
By default, I get output of attributes like this:
<created-at type="datetime">2009-01-09T02:58:31Z</created-at>
<id type="integer">110</id>
<reference>From Anne</reference>
When I do #to_xml. Notice the date format for the type="datetime".
What is the actual class of error_date? Is it a Date or a DateTime or
a Time?
