Documentation issues ... cloning folders into instances
by Joachim Werner 01 Apr '00

01 Apr '00

<frustration> I'm finding myself again trying to figure out how things work in Zope, just to find out at the end that it is MUCH simpler that I thought -- but totally undocumented! Or maybe I just haven't looked for it enough ... Isn't there somewhere a list of all method calls I can use from DTML (like manage_addXYZ)? It can't all be just trial and error or "read the code". -- Yes it can, but I don't want to be that pessimistic ;-) O.k., my current problem is that I have a folder with icons and images in a ZClass that should be copied to all new instances of the class. There seems to be a "manage_clone" call for that (just read about it in a posting), but how does it work and where do I find any documentation on it? As all those methods are in the namespace, isn't there at least a trick to get a list of all names to print out? That would be a first start. I mean, I had to figure out every single call like manage_addDTMLDocument or manage_changeProperties by trial and error. That makes Zope so much less efficient that it could be ... </frustration> Joachim Werner.

Zope ISP giving access to Products folder?
by Darran Edmundson 01 Apr '00

01 Apr '00

On behalf of an ISP who has now installed Zope (on my behalf) ... Does giving ClientX 'Manager' access to Control_Panel/Products/ClientX_Product open up any security holes? The alternative is to have ClientX develop on his local machine, save out ClientX_Product.zexp, and ship it over for us to install. Comments? Cheers, Darran.

Zope/Interbase/ODBC resolution
by Graham Chiu 31 Mar '00

31 Mar '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I previously posted that I was having problems with Zope and Interbase losing the ODBC connection ( on Win32 ). This would happen whenever I entered the web management interface, and at other times when I could not identify a cause. I then had to shut Zope down and restart it. Zope would not allow the ODBC connection to be made otherwise. I was using the much older Visigenic driver because the Intersolv driver truncated varchar fields (a known bug). However, recently I joined the Interbase mailing list, and one of the Interbase staffers suggested I retry the Intersolv driver and recast the varchar field as char to work round the truncation viz. select cast(myvarchar as char(n)) as myvarchar from foo; I am pleased to report that this works well, and over the last few days I have not observed a single disconnection. Furthermore, I have noticed that the very first use of the OBDC connection after Zope started always gave an error. This problem has also now disappeared. For interest, my experimental server is using a PII 300 overclocked to 450, 128Mb ram, NT4 server, and an IDE hard drive served on an ADSL connection. There are about 20,000 items in the ecommerce database. I am also using Interbase to do Zope session management. You can reach the server by using the url below ( a PHP script on my static server redirects to the ADSL box). I'll post an update if the situation changes. In addition, Interbase Corp has expressed an interest in supporting Zope by helping/writing native drivers for Linux and other platforms which are supported by the new Open Source Interbase 6.0 - ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/x.php?/Shopping -----BEGIN PGP SIGNATURE----- Version: PGPsdk version 1.7.1 iQA/AwUBOOSMmbTRdIWzaLpMEQI2agCgwGVCB+/54azaocujM+ewVCq3RLIAoJtw Lj3Ney3HRWunOqfwKh5ZB1FX =5xb/ -----END PGP SIGNATURE-----

Hmm, here is what I have, in DTML Method aaabbbccc:: <dtml-var standard_html_header> <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p> <dtml-let foo="'bar'"> <dtml-var asdf> </dtml-let> <dtml-var standard_html_footer> And in DTML Method asdf:: <p> <dtml-var foo></p> When I view aaabbbccc, I see:: Calling asdf with variable 'foo' = 'bar', using the let tag: bar which is exactly what I expected. Can you see any differences between your code and mine? Tres. -- ========================================================= Tres Seaver tseaver(a)digicool.com tseaver(a)palladion.com

What's the most elegant way to shut down a folder to public access while doing maintenance. I wondered about using a redirect in the standard_html_header but that doesn't seem to work... ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

User quotas
by Pierre-Julien Grizel 31 Mar '00

31 Mar '00

Hi, 1- Is there a way to keep user quotas on Zope objects ?... I.e. restrict the amount of place a user can waste with its objects. I briefly looked at the list's archive but did not find the actual answer. 2- Is there a way to purge the ZODB object history (ie. not the cache but the older versions of each object) once I have a stabe "release" of my website ?... It would take less space on disk, and I suppose rendering will be faster. Thanks, P.-J. Grizel

Status of the PTK (Portal Toolkit)
by Alexander Limi 31 Mar '00

31 Mar '00

Hi. I would just like to know how far the PTK has progressed. Is the code sufficiently complete for me to create a user with individual preferences/properties yet? I don't need the whole shaboodle, user code will do me fine right now. And please CC me, I'm still not on the list :( Regards, Alexander. Who would prefer _not_ to implement his own proprietary "user with properties" code. :)

Zope in Jpython
by Sin Hang Kin 31 Mar '00

31 Mar '00

Zope is greate, all reviews say so. Most of the reviews complain the documentation. I believe all come to known zope have experience the same difficults and all those remains can feel the power of zope. Not only the documentation is matter. Under the greate architecture, zope is inconsistance, non-intutive, and mistiness. To be fast to market is not enough, it must also easy to maintain, endure greate and fast change to make zope success. To make good use of zope, one should paid more attentation on content instead of control. Making separation of control and content as deep as possible. Write re-usable, structural components. I believe the following is very important : 1. re-introduce unified naming convention. encourage developers to change over this 2. move un-necessary codes from the zope kernel to user space: <base> <lang> ... 3. support of unicode 4. make zope content easy to co-operative with current technonlgy especially search engines. zope oodb is greate, but it prevent other apps to access the data, so it is difficult to contruct a local search facility. 5. support cvs style versioning 6. multiple output format 7. new scripting language, encourage separation of content and control, may be more xsl and xpointer style. Converting zope to Jpython have the following benefits: 1. Unicode support 2. draw other java components : for example, several xml tools being develop in Apache.org is very useful. If a complete re-write is not economic, at least DC should consider how to separate the content and control in zope, make the syntax easy to learn and use. Rgs, Kent Sin

>i don't know what more tell you about the error. In case you have not realized, what you have provided is NOT an error message. I don't know why you call it an error message. That is why I asked you to provide the error message. :) If you have an error message, please provide it. If not, please don't call something an error message when it is NOT. Por Dios, si no hay error, para que me asustas? :) Please read the README.txt file and follow the steps there. (1) First check your environmental variable is properly pointed. Do echo $SYBASE if it does not show the directory of installation of your Sybase database, you are in bad shape. You need to set this environment variable, preferable from the moment you reboot the machine, but if not, from your Zope's "start" file. SYBASE=/mnt/sybase1192 export SYBASE (2) Follow the instructions in README.txt cp Setup.linux Setup make -f Makefile.pre.in boot make cp sy_occ.so .. Then it'll work. (Me parece que tu problema no es Sybase adapter, tu problema puede ser Unix/Linux. Parece que no eres familiar con Unix/Linux.)
