Creating instance in current folder
by Bodo Bauer 02 Mar '01

02 Mar '01

Hi, I'd like to create a TinyTable using DTML in the current folder and am not quite successful. The table gets created, but in the parent directory. I have a Zclass with a dtml-method which test the existence of the table and if it's not there already it's supposed to create it. Note that this of cource happends in the instance of this class. Everyhting seems fine, exept tht fact that the table isn't create where I want it to. Here is the code I use: <dtml-if xref_table> UPDATE<P> <dtml-with xref_table> <dtml-call "delAllRows()"> </dtml-with> <dtml-else> NEW!<P> <dtml-call "manage_addTinyTablePlus('xref_table', 'xref', 'label number url type')"> </dtml-if> ... more stuffi ... I tried several permutations of PARENTS[?].manage_addTInyTablePlus(...), but I never got it to create the table in the current directory. Can anybody help?

ZMySQLDA 2.0.0 and Time fields
by Peter Bengtsson 02 Mar '01

02 Mar '01

Got it! Hacked it :) In ZMySQLDA 2.0.0 there is a bug when using a time field. What happened was that when I select-query a table with TIME (not datetime or timestamp or date or anything normal like that) The ZMySQLDA tried to convert that using DateTime. That failed. >>> print DateTime('00:00:01') Traceback (innermost last): File "<pyshell#4>", line 1, in ? print DateTime('00:00:01') File "C:\Program Files\Zopesite\lib\python\DateTime\DateTime.py", line 711, in __init__ yr,mo,dy,hr,mn,sc,tz=self._parse(arg) File "C:\Program Files\Zopesite\lib\python\DateTime\DateTime.py", line 1050, in _parse raise self.SyntaxError, string Invalid Date-Time String: 00:00:01 Solution: Somewhere in db.py search for DateTime from bottom and up. The first line there can be removed from the conv {}-dict. Let it be. Peter

Re: [Zope] Newbie

Adam: Check out this HowTo: http://www.zope.org/Members/Caseman/client_script_howto I personally find it is pretty easy to use javascript with Zope. Basically, if I want to use javascript (like mouse-overs), I create a dtml document containing the javascript I want Then, I modify the "standard_html_header" method and add something like this: <dtml-if js_Rollover_Insert> <dtml-var js_Rollover> </dtml-if> Then, whatever DTML document I want to insert the javascript code for the mouse-over (ie "index_html"), I add a property called "js_Rollover_Insert". The value is not necessary, I use "Yes" for clarity. What then happens is that whenever that "index_html" is called, the property js_Rollover_Insert is added to the namespace. Then, as Zope goes through the namespace rendering objects, you eventually hit standard_html_header. Since the property js_Rollover_Insert is in the namespace, the <dtml-if> statement will evaluate to true and render whatever is in the object "js_Rollover". Hope I haven't confused you... Just as a side note, I started out using IIS/Delphi to write a web application for the LAN group I was in at the time. I did a pretty good job of writing the site; however, once I discovered Zope, and got through the learning curve, I was able to rewrite the site in less than 1/2 the time it took me to write the CGI scripts/ISAP DLL's. It was also a *lot* easier to go back and add functionality as it was needed. If you are considering using a DB to store your data in, Zope will *really* outshine writing CGI/ISAPI in Delphi.

data point on ease of learning Zope -- I give up.
by zooko＠zooko.com 02 Mar '01

Hi Zopesters! I'm an experienced Python programmer, and I need to hack together a quick web app that simply accepts POSTed XML data entries from authenticated users, stores the data persistently, and provides a formatted HTML representation of the list of all such entries to the same authenticated user. I thought I would look at using ZODB so that I could have the coolness of nearly transparent persistence. Then I thought I would use Zope so that I wouldn't have to bother with connecting the HTTP transactions to the logic. So I did `apt-get install zope'[1] to download and install the current Debian-packaged version of Zope (v2.2.4), and while I was waiting on the download I went to zope.org. It is now about 3 hours later and I have not yet found any "example code" or instructions that shows how to set up a basic web site or how to write Python code that gets executed, CGI-style, in response to an HTTP transaction. I browsed zope.org, the ZDP, and a site called "ZopeNewbies". I looked at the "QuickStart" that came with the zope server, but all I saw was how to edit web pages using DTML. I don't want to have anything to do with DTML (though we use it in my product, Mojo Nation[2], which BTW is probably the second-biggest open source Python app, after Zope), and I don't want to edit any static pages, so I stopped reading the "QuickStart". So now I give up. I'm going to install apache (`apt-get install apache'), and use the Python bsddb module for a simple dict-like database. Even though I wasted about half of my scheduled time on trying to set up a basic Zope server, I'll probably still have my prototype up and running 3 hours from now, when I have a meeting with my co-workers.

can't login to Zope!
by Stuart Quimby 01 Mar '01

01 Mar '01

A newbie problem here. I can't seem to login to Zope no matter what I try. - I've installed Zope 2.3.0-1 and ZServer 2.3.0-1 from rpm's accessible from the Zope.org site on a RH 7.0 machine. - I run /etc/rc.d/init.d/zope start and it starts fine. - I open Mozilla to :8080 and the Zope start screen displays. - Tried pointing the browser to :8080/manage and it asks for username/passwd. - I supply admin and 123 and no go. No error message just keeps asking for the password again. - Cruise the docs and mail list archives. - Run python zpasswd.py inituser and reset the password. (This was suggested on the mail lists - I couldn't find it in the docs.) - Verify that the inituser file was changed. - Close all browser windows. - Run /etc/rc.d/init.d/zope restart. - Open browser and try to log in again. - Same response. - Try running python zpasswd.py access. - Close browsers/restart zope/open browsers - same response - no error messages - just doesn't like the usernames and passwords I'm providing. - Thought maybe it was a 'Mozilla thang'. Tried Netscape. Same response. This is pathetic. I've got 6-7 hours into this just trying to get the management interface up!!! Can anyone point me to how to get this thing running?

data point on ease of learning Zope -- I give up
by Donald Braman 01 Mar '01

While I probably abuse the list by doing this, if I can't find documentation after an hour of searching, I post a note to this list and they have an answer (like the one Phil just posted). I'm often looking in the wrong places or for the wrong thing. But the point about learning to use Zope is a good one. The "Learn Zope" page should have a channel for newbies and for experienced programmers. If people can find what they want quickly, they may not stick around long enough to see. Also, maybe a more detailed TOC for the Zope Book would help (like in the Postgres documentation). Looking at the Zope Book TOC doesn't really show you where to find the Python/XML bits (though "Advanced Scripting" is a nice clue). I sympathize, Zooko, I too suffer from poor searching capabilities. And there are others out there like us, I am sure. -Don +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ [Zope] data point on ease of learning Zope -- I give up. zooko(a)zooko.com zooko(a)zooko.com Thu, 01 Mar 2001 13:59:00 -0800 Hi Zopesters!

xmlrpclib in python scripts
by magnus/Websys＠websys.no 01 Mar '01

01 Mar '01

We've started using XML-RPC with Zope and Java. Works fine, using external methods (Zope is the client). However, it would be neat to be able to use XML- RPC in python scripts. How do I validate a new module (xmlrpclib) for importing into python scripts? Of course, an XML-RPC client product would be even sweeter :-) -Magnus
