cal is a string not a file. I am not a Zope user though so I might be talking nonsense Pavlos

I'm inching along. Thanks to Michel Pelletier and Andy Kuchling, I now know my calendar module is a Product and what most (all?) of the necessary scaffolding is. My Calendar class supports a show method:

def show(self, year, month=0): """return plain ASCII calendar

month == 0 ==> display calendar for entire year """

if year < 1 or year > 9999: raise ValueError, ("year out of range: %d" % year) if month < 0 or month > 12: raise ValueError, ("month out of range: %d" % month)

if month: cal = os.popen("cal %s %s" % (month, year)).read() else: cal = os.popen("cal %s" % year).read()

return HTMLFile('cal', month=month, year=year, cal=cal)

Is this Globals.HTMLFile or DocumentTemplate.HTMLFile?

When I access

http://localhost:8080/Calendar/show?month:int=0&year:int=1998

I get the following traceback:

Traceback (innermost last): File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/ZPublisher/Publish.py, line 861, in publish_module File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/ZPublisher/Publish.py, line 585, in publish (Info: /Calendar/show) File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/ZPublisher/Response.py, line 284, in setBody File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/DocumentTemplate/DT_HTML.py, line 217, in __str__ (Object: /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/cal.dtml) File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/DocumentTemplate/DT_HTML.py, line 209, in quotedHTML (Object: /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/cal.dtml) File /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/DocumentTemplate/DT_String.py, line 532, in read_raw (Object: /home/dolphin/skip/src/Zope-1.9b1-src/lib/python/cal.dtml) IOError: (2, 'No such file or directory')

which suggests to me that my cal.dtml file is not where Zope expects to find it. All files in my Products/Calendar directory are in that directory:

% ls -F lib/python/Products/Calendar/ __init__.py cal.dtml vcal.gif __init__.pyc cal.py addCalendar_form.dtml cal.pyc

Why is it looking up two levels in the directory hierarchy for the DTML file?

I bet that you are running Globals.HTMLFile, which assumes that DTML files are in SOFTWARE_HOME.

As far as I can tell, I'm using the same calling conventions for HTMLFile objects as the MailHost and sample Products do.

Not quite. If you look closely, you'll see that HTMLFile is used to create methods and that it's usually called with globals() passed in. This allows it to figure out where the calling package is located so that it can find the DTML file. I think you want: _show=HTMLFile('cal',globals()) def show(self, year, month=0): """return plain ASCII calendar month == 0 ==> display calendar for entire year """ if year < 1 or year > 9999: raise ValueError, ("year out of range: %d" % year) if month < 0 or month > 12: raise ValueError, ("month out of range: %d" % month) if month: cal = os.popen("cal %s %s" % (month, year)).read() else: cal = os.popen("cal %s" % year).read() return self._show(self, month=month, year=year, cal=cal) I assume that you want to return the rendered template, right? In your version you were just calling the constructor. It's better to call the constructor in the class definition so that you don't pay construction and compilation costs on each hit.
