by Stuart Foster 05 Sep '00

05 Sep '00

I know I've seen many posts about this, I just can't find one. I need to put the current date into an input's value when a form is loaded. Is there a way to do this with DTML. TIA Stuart

Help with calcualtions in DTML
by Dario Lopez-K�sten 05 Sep '00

05 Sep '00

Hello! I have the following listing of objects in my folder: <table> <tr> <td>Name</td> <td align="right">Size</td> <td align="right">date</td> </tr> <dtml-in expr="doc.objectValues()"> <tr> <td> <a href="<dtml-var absolute_url>"><dtml-var id></a> </td> <td align="right"> <dtml-var get_size> bytes </td> <td align="right"> <dtml-var bobobase_modification_time fmt="%Y-%m-%d %H:%M"> </td> </tr> </dtml-in> </table> It gives me the name of the object, the size in bytes and the modification time in GMT. I need to do the following: express the size in kb, format the output with spaces for thousands. I also need the date displayed according to my locale (+2 GMT in Sweden) so if bobobase_modification_time is 10:48, I need to show it as 8:48, and on top of that I also need to take dayligth savings into account. How do I do it? The fmt strings are abviously adjusted to US standards, so us ISO-people need to hack our own format strings :-). I know i could calculate the size in KB myself IF I only knew how to get the get_size attribute into a calculation expression (that goes for bobobase_modification_time as well, however this returns as string. How do I get the date as a date?) Any help is appreciated and needed. Thank you. /dario PS: has anyone been thinking of renaming bobobase_modification_time to something shorter and more intuitive, like, say, modification_time? :-)) - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services

illegal id chars?
by Jason Byron 05 Sep '00

05 Sep '00

Why is it that objects can't be created because the id chosen contains characters that aren't proper in urls? Spaces are allowed and converted to their hex values when you create an object. Why not do this with every illegal url character? I must me missing something here because this seems like this should have been one of the first things designed into Zope. Right? __________________________________________________ Do You Yahoo!? Yahoo! Mail - Free email you can access from anywhere! http://mail.yahoo.com/

That :method thingy.. where's it documented?
by Brad Clements 05 Sep '00

05 Sep '00

I've searched through all the how-toos and documentation on the zope site, but I can't find any reference to :method types.. I know they exist, but searching for "method type" returns too many hits. Can someone remind me where to find this documented? Thanks Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements

External method and stdout
by Sven Hohage 05 Sep '00

05 Sep '00

Hallo, that's the problem: I've made an external method which is working with lists and should return the result to Zope. The python code is working very well, but is sending everything to sys.stdout( I'm using the print-statement).How do I convince Zope to print the result on the html-page. Thanks.

RE: [Zope] Folder and SQL security

George, Hi... please continue to respond to the list... Did you clear the acquire permissions settings checkbox for all the permissions in the "wholesale" folder? Does it make any difference?

For the Zope community
by Shane Hathaway 05 Sep '00

05 Sep '00

Zopistas, It has been very rewarding to work with DC and the Zope community. I have learned a lot about software and community spirit. I have never had the opportunity to work with a more enthusiastic and dedicated group of developers. So at this time I'm releasing two new products designed to help Zope users to get their job done more easily. http://www.zope.org/Members/hathawsh/ZDebug/index_html ZDebug is a set of patches to Zope that help in the deciphering of DTML errors and authorization exceptions. Because this is the first release, remember to make a backup before installing. http://www.zope.org/Members/hathawsh/tcpwatch/index_html TCPWatch is a simple Python script that lets you monitor a TCP connection. It does *not* depend on Zope, but it can be especially useful when writing Zope apps for WAP devices because the WAP devices will not display Zope exceptions while TCPWatch will. It's also useful for debugging any TCP/IP-based protocol implementation. Keep up the awesome work! Shane

Re: [Zope] DTML horror

They may be available in all installations but they aren't necessarily available to all users )-: Have fun, Murph (who is not actually complaining given the price he has to pay for use of a public Zope server) >>> Rik Hoekstra <rik.hoekstra(a)inghist.nl> 05/09/00 11:51:35 >>> Use Python Methods (http://www.zope.org/Members/4am/PythonMethod) or External Methods (available in all Zope installations RTFM). They will probably not completely replace DTML though.
