[mod_python] Using Templates

Hi Ron,

I'll have some additional comments later, but I just noticed that you 
have a name collision in your month.tmpl. Whatever loadCalendar.strDate 
is will override the value of strDate you set in the line tmpl.run(vars 
= {'strDate': strDate})

def setStrDate(req):
	if not hasattr(req, 'session'):
		session = initSession(req)
		strDate = ""
		session = Session.Session(req)
		strDate = getSessionVariable(session, 'currDate')
	req.content_type = 'text/html'
	tmpl = psp.PSP(req, filename='Month.tmpl')
	tmpl.run(vars = {'strDate': strDate})
	return ""

from mod_python import apache, psp
from loadCalendar import loadMonth, strDate
                                     What's this?


<%=loadMonth(req, =strDate)%>
