[Zope-dev] Calling HTMLFiles

[Morten W. Petersen]

Hi,

I'm having difficulties calling an HTML file from python..

Here's the code:

[...]
from events import conflicting_events

calendar_event_add_redirect = HTMLFile('calendar_event_add_redirect',
					globals())
manage_add_calendar_event_form = HTMLFile('calendar_event_add', globals())
conflicting_events_dialogue = HTMLFile('calendar_event_conflicting_events_dialogue', globals())

# These two expand into seconds
expand_hour = lambda x: x * 60 * 60
expand_minute = lambda x: x * 60

def manage_add_calendar_event(self, title='', note='',
				alarm=0, start=0, end=0,
				priority=0, status=0,
				REQUEST=None, RESPONSE=None):
	"Add an instance of the calendar_event class."

	new_id = str(self.get_unique_id())

	if REQUEST:

		alarm = expand_hour(REQUEST['alarm_hour']) + \
				expand_minute(REQUEST['alarm_minute'])

		start = expand_hour(REQUEST['start_hour']) + \
				expand_minute(REQUEST['start_minute'])

		end = expand_hour(REQUEST['end_hour']) + \
				expand_minute(REQUEST['end_minute'])

		title = REQUEST['title']
		note = REQUEST['note']
		priority = REQUEST['priority']
		status = REQUEST['status']
		
		
	conflicting_events_ = self.check_timespan(
		self.getParentNode().getParentNode().id,
		self.getParentNode().id, self.id,
		start, end)

	if conflicting_events_:
		
		return conflicting_events_dialogue(self, REQUEST)
[...]

Now, if there are any conflicting events, the HTMLFile is returned, with
some parameters passed along.

What I'm wondering about is how can I pass the variables defined
in the REQUEST so that they can be looked up with dtml-code in
the conflicting_events_dialogue?

And doing it without raising KeyErrors on DTMLMethod that are
called from within the conflicting_events_dialogue?

Thanks.
