Answering my own question: _.int(ZopeTime) You appear to be able to pick whether that is in localtime: _.int(ZopeTime) or GMT terms: _.int(ZopeTime ('GMT') Perhaps the maintainer of the dateTime HOW-TO would add this data to the HOW-TO? -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

Getting the epoch time as an integer
by J C Lawrence 24 Jan '00

24 Jan '00

How do I get the current time as the number of seconds since the Epoch? I know I can use ZopeTime in various interesting ways to get a pretty string that expresses the current time/date in human readable format. I don't want that. I want the raw integer number of seconds since 1970. I've been thru the HOW-TO, thru the DTML guide and all the option and format strings and I just don't see it (or I'm going blind). Surely there's a way to get just the raw time_t? -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

<dtml-sendmail> problems
by Stephen Pitts 24 Jan '00

24 Jan '00

The following code generates an "SMTP Error 503: No receipients specified". <dtml-sendmail mailhost=mailhost> From: "<dtml-var from>" To: "<dtml-var firstname> <dtml-var lastname> <<dtml-var toemail>>" Subject: <dtml-var subject> <dtml-var messagebody> </dtml-sendmail> The variables are set as follows: from - "Stephen Pitts <smpitts(a)midsouth.rr.com>" firstname - "Stephen" lastname - "Pitts" toemail - "smpitts(a)midsouth.rr.com" subject - "Stuff" messagebody - "Enter your message body here" How can I fix the code so it sends a valid email? Does Zope not support To/From fields of the type "name email(a)address.com"? -- Stephen Pitts smpitts(a)midsouth.rr.com webmaster - http://www.mschess.org

Does Zope wait until it completely renders a page before sending it back to the client or does it send as it is rendering? Jim Sanford snafford(a)bellsouth.net

Control of the +/- images for trees
by J C Lawrence 24 Jan '00

24 Jan '00

I saw traffic and patches in the archives to define different images for the control nodes on DTML trees. Did any of these get accepted? Is there currently a way of defining what images you want used instead? -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

Trees under SQL -- a correction and a question
by J C Lawrence 24 Jan '00

24 Jan '00

I'm attempting to built a DTML tree using a ZSQL method almost exactly as detailed in the "Some Neat Tricks with dtml-tree" HOW-TO at: http://www.zope.org/Members/anthony/tree-coding-tricks A minor correction to the initial DRML example, which reads: <dtml-let objectid="0"> <dtml-tree id=objectid branches_expr="child_lookup(parentid=objectid)"> <b><dtml-var objectname></b> <dtml-var objectid> </dtml-tree> </dtml-let> This is incorrect. The name assigned to "id" in the dtml-tree line needs to be single quoted making the method read: <dtml-let objectid="0"> <dtml-tree id='objectid' branches_expr="child_lookup(parentid=objectid)"> <b><dtml-var objectname></b> <dtml-var objectid> </dtml-tree> </dtml-let> However, I have a more subtle problem. For me the equivalent of "objectID" is an 8 byte BIGINT, and thus the result from the ZSQL method for that column is suffixed with an 'L' (eg "42L" for object number 42). This screws up the dtml-tree royally. Is there a way to work around this? -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

I want to be able to tell whether a method exists or not. Specifically a method of a certain name that can exist somewhere in the aquisition path.
