Suppose I have a folder object and a string containing the id of a file in that folder. How would I remove a file in that folder on the zope filesystem using the Zope API from within a Python Script? Thanks, John Hunter

PS. they're really the same Newspaper. Mike wrote: A piece also appeared in today's Sydney Morning Herald - IT section, page 2. I'd guess it was the same piece. The URL for the words is: http://www.it.mycareer.com.au/news/2002/03/19/FFXF7G6VSYC.html

Piece on Zope and OzZope in today's Age IT section.
by Anthony Baxter 19 Mar '02

19 Mar '02

There's a nice piece on Zope in today's issue of The Age IT section (or whatever it's called now). I've not been able to find it on the age website (www.theage.com.au) - I suspect that they must update the site at different times than the paper stuff.

Re: [Zope] Passing Dictionary (ZPublisher.HTTPRequest.record)
by Ronald L Roeber 18 Mar '02

Thank you Dieter, You were correct. I had used 'records' instead of 'record' in the input tag. I made the change and all works as advertized. That I got an object that looked close to what I was looking for kept me from seeing the obvious. Many thanks. Sorry for the trouble.

Strange. I can do that. Are you sure, you use a record instance? I tested with the following form/action pair: test_record_form: <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <form action="test_record_action"> <p> <input name="a.a:record" value="a" type="hidden"> <input name="a.b:record" value="b" type="hidden"> <input type=submit> </p> </form> <dtml-var standard_html_footer> test_record_action: <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <p> <dtml-var expr="a.items()"> <dtml-var expr="a.copy()"> </p> <dtml-var standard_html_footer> I remember that your original post mentioned ":records" not ":record", then your object is a sequence of "record" objects. You need to first select a single record object (throuch subscription with integers, e.g. "o[0]") and can then use the record methods and attributes. Dieter
