I think (this implies, I am not sure), that ZPublisher translates exceptions into HTTP response codes. This would mean, you could try: In your "privacy" method: .... <dtml-call "RESPONSE.redirect(...)"> <dtml-raise type="Redirect"></dtml-raise> .... in your other objects: <dtml-call privacy> ...header... .... ...footer...

Re: [Zope] get property of type 'list'

If it were, it would be really strange, unbelievable. ['1', '2', '3', '4'] would be normal, when you use a list (it definitely is one!) in e.g.: <dtml-var "_.getitem('toks')"> as a list (of cause) can not be part of a generated HTML page. It must be converted into a string. And the above it the string representation of a list. To get the representation, you seem to favour (though I do not understand why), you could use: <dtml-var "_.str(_.getitem('toks'))[1:-1]"> This make the string conversion explicitly ("_.str") and then keeps the slice "[1:-1]" which means everything beside the first and last character, i.e. you chop the '[]'.

Re: [Zope] REPOST: dtml-with doesn't work
by Dieter Maurer 10 Jan '01

Usually, I complain that problem reports are too terse. But, your's was very big, such that I did not read it carefully. It is very difficult to get it right for everyone. Just a remark: SQL methods do *NOT* look at the DTML namespace *AT ALL*, just at REQUEST (or the expliciitly passed keyword arguments). Thus, "dtml-with", "dtml-let" and friends are all ineffective with respect to ZSQL methods. May be, that explains your problem. May be not, as I am not sure, that you need the values indeed inside a ZSQL method. I can assure you: "dtml-with" does work. Dieter

The data displayed can be anywhere, for example in a database. If you have a small database with your holidays or other relevant events, then such a calendar should be easy to realize. Dieter

And what error do you get? I tried: from DateTime import DateTime def f(): return DateTime('2001/01/09') and there was no problem. Dieter

Storing and Using Object references
by Tom Jenkins 10 Jan '01

10 Jan '01

Hello all, i have a question and I hope someone can point me in the right direction to solve it. I need one zope object to hold a reference to another zope object so the first object can call methods of the second object. oh, these are python classes. Example: object 1 is : /container1/container1a/item1 object 2 is : /container2/container2a/item1 object1 needs to hold a reference to object2. I'm really stuck on how to store and access object2 from object1. any pointers? Tom Jenkins devis - Development InfoStructure http://www.devis.com

Trouble with dates in an External Method
by Steven Grimes 10 Jan '01

10 Jan '01

I'm having trouble using dates in an external method. I can't get it to import the python DateTime module. I need to compare two dates which are in string form in the external method. I know that this isn't a good description of what I'm trying to do but I'm new to Zope development. If this should go to a different mailing list please let me know. Thanks in advance for any help, Steven

Re: [Zope] slow DocumentTemplate (dtml) import speed
by Dieter Maurer 10 Jan '01

Federico Grau writes: > ... import of "DocumentTemplate" in CGI script takes too much time ... Check whether your Web Server supports FCGI. If the Web Server is Apache, then there are several Apache modules to integrate Python inside Apache. I think Guido van Rossum uses "mod_snake". Search "comp.lang.python" via "www.python.org" or "dejanews". All these approaches would save you the new process spawn and the build up of its infrastructure all together. If you cannot use any of these options, then the Python "freeze" facility may help you. Dieter
