I don't have a direct answer to your question; but I thought I'd mention (in case you hadn't are ready seen them) the date-handling features built into DTML that make this kind of transformation easy. Check out Appendix A of http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html

Thanks, however I think they only work on date objects. There is a DateTime() function to create date objects mentioned in the DTML guide, but it doesn't seem to be documented. Nevertheless, I would be interested in why atoi does not work for me. ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

There is a DateTime() function to create date objects mentioned in the DTML guide, but it doesn't seem to be documented.

Okay, it's simple enough -

<dtml-call "REQUEST.set('mydate',_.DateTime('2000/12/31'))">

creates the date object I need to then reformat it.

Oops, spoke too soon. Spent the last few hours trying to suss this out without any progress :-( I have a variable called START returned by a sqlquery <dtml-call "REQUEST.set('startdate',START)"> start is <dtml-var startdate> and that's okay <dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth"> That, and variations of the same, dies with Error Type: TypeError Error Value: __div__ nor __rdiv__ defined for these operands Why is that these simple little things are so difficult in Zope? ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

Another way of doing this, however, is something like the following:

<dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))"> <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate fmt=year>

I forgot that you can also use C-style formatting, which reads much better in this case: <dtml-var mydate fmt="%d-%b-%Y"> See: http://www.zope.org/Members/AlexR/CustomDateFormats --Jeff --- Jeff K.

I'm still having difficulty with this. I want to add a date to a character string ( dated user comments ) to store into a sqltable. <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)"> The docs say that this returns a date string ( as opposed to a date object? ) <dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)"> produces this error Error Type: TypeError Error Value: illegal argument type for built-in operation And if I try this <dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))"> mystring is then 'date:' ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/x.php?/Shopping http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">

This is the same problem as last time. You must CALL the Date method, not just reference it. The above line should read: <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()"> Note the use of parens on Date(). Try it for yourself by putting the following in a DTML Method: <dtml-var expr="ZopeTime().Date"> You get: <method DateTime.Date of DateTime instance at 568eb0> if you do a View | Source in your browser.

The docs say that this returns a date string ( as opposed to a date object? )

It does, if you CALL it.

<dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)">

produces this error

Error Type: TypeError Error Value: illegal argument type for built-in operation

Here is some code that works: <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())"> <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)"> <dtml-var mystring>

And if I try this

<dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))">

Again, you've never set CurrentDate correctly. View the source of the page that comes back and you will see the problem.

mystring is then 'date:'

Hope this helps. --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff@goingv.com Going Virtual, L.L.C. http://www.goingv.com/

What had me confused is that

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())"> <dtml-var Currentdate>

and

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)"> <dtml-var Currentdate>

both display the same date string whereas I guess the latter should display an error. It only reports an error when I try to do something else with the variable.

In the second case, I guess <dtml-var CurrentDate> is recognizing that CurrentDate is a reference to a function and calling it. I understand, now, how that had you confused. Anyway, glad it's working! --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff@goingv.com Going Virtual, L.L.C. http://www.goingv.com/
