Dynamically choosing a ZSQLMethod to run
by Michael Wang-Helmke 06 Jan '00

06 Jan '00

hi all, I have an application where I have several different SQL queries I want to do but I want to use the same DTML method to render the output. I imagine that I should be able to store a reference to a ZSQLMethod in a variable like thing and set it to the right query before I call the DTML method. Otherwise it seems like I need N display functions for the N queries. How can I do this? I have moderate experience in Python and enough experience in Zope to have built a bug tracking database system entirely in DTML (no external methods or external python products). thanks Michael Wang-Helmke Play, Incorporated

RE: NT User Folder

> I have a question in regards to your > jcNTUserFolder..........how can set the > folder to authenticate to a remote Domain Controller? When a user identify himself as USERNAME, it is considered to be DEFAULTNTDOMAIN\USERNAME. So I you want to authenticate users on a different domain than the local domain, you have to change the Default NT Domain to the remote domain. I suppose that your server have to be part of the domain. Unfortunately, you have then to create each remote user in the 'domain users' tab **in order to be able to give them roles**. If those users are to be anonymous, you needn't create them in the tab. Also, a user can log as DOMAIN\USERNAME to authenticate as USERNAME on DOMAIN. My product is currently designed to be run *on* a Domain Controller (primary or backup) to be able to enumerate all the users of the domain. Perhaps in a future version it will be able to enumerate users on a distant server??? > In addition, when I use your product....the local Domain Name > it sees is "NT Authority" This is normal because you run Zope as a service. I noticed that the users are authenticated the right way nevertheless. So it shouldn't be a problem. If you are in doubt, change the default nt domain > When I run the win32api.GetDomainName in the PythonWin I would get the > correct Domain. Pythonwin is not run as a service... :-) > What can I do to change this? It shouldn't be a problem. users should be authenticated the right way. If you have problems, I am interested to hear about them. PS: I hope to write some docs very soon. I apologize to release a product without any docs. As usual, the source is to be read to understand how the product work :-) Regards, Jephte CLAIN minf7(a)educ.univ-reunion.fr

comparing <dtml-var> values
by Timothy Wilson 06 Jan '00

06 Jan '00

Hi everyone, I can't find the answer to this anywhere. How do I compare the values of two <dtml-var> tags inside a <dtml-if>? Specifically, <dtml-if "<dtml-var var1> == <dtml-var var2>"> do something </dtml-if> That obviously doesn't work, but I can't figure out what would. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Re: [Zope] Versions and FTP access
by Jon Prettyman 06 Jan '00

06 Jan '00

Given an object: /folder/object And a version: /folder/versionN Couldn't the FTP server be made to return the original object if the request is for /folder/object and the ``versioned'' object if the request was for /folder/object/versionN ? It seems that this would work for GETs and PUTs. Jon Michel Pelletier <michel(a)digicool.com> writes: > > ... > > You cannot work in a version through FTP.

Extending ZSQL methods to zope objects
by Chuck Burdick (TT) 05 Jan '00

05 Jan '00

Does anyone have some simple (and useful) examples in which the results from ZSQL methods are extended to be zope objects? I'm trying to figure out what is possible and what is not. Right now, the documentation in the ZSQL guide gives a trivial example of an extension. However, the guide only eludes to tying together ZSQL results with a URL (ex: http://some.zope/myfolder/myzsql/lastname/Smith) and does not really explain how this works. I would love to see some more realistic examples of using ZSQL methods in a powerful way. Can you use the URL to define searches and filters based on ZSQL results and inherit the index_html from a base folder? What else is possible? It seems that simple-yet-powerful integration of Zope with SQL datasources is crucial to Zope's success. Maybe DC can enlighten us on some ZSQL best practices.

Installation Routes Comparison
by Guy Davis 05 Jan '00

05 Jan '00

I have been struggling with Zope installation for the last few days and decided that a pros/cons comparison of the different installation routes would have been helpful for new users. I have written one at: http://www.zope.org/Members/guy_davis/install_routes. I would like to make sure that any corrections and ommissions (I'm sure there are some) are fixed, so please email with any you find. Thanks. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council

PCGI uses Rewrite module, which is a complex Apache facility, and otherwise, configuring Apache sometimes may be complicated. The best thing you can do is to browse the zope(a)zope.org archive (1999 oct - dec) for Apache, PCGI, or read some invaluable HOW-TOS. To whet your appetite here is my receipe (with some technical background) how to install Zope with Apache on RH6.1. If you manage (I am sure you will) to install Zope+PCGI+Apache, please write us what was the cause of your problem. It would be very nice to collect a list of troubles with Apache+Zope installation.

There are a couple of how-tos on this allready. Ok, like the "Formatted Document" product used on the Zope site. So basiclly: don't use DTML Document/Method, subclass them to do what you want them to do, instead of a lot of dtml-tags inside of them? That way you get different meta-type tags for different type of data, and zcatalog can handle them properly...? Am I getting it right? -- /Magnus Heino

Zope Weekly News
by Mike Pelletier 05 Jan '00

05 Jan '00

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday evening. Any opinions contained in the Zope Weekly News are those of the chronicler exclusively. Announcements * A security hole has been found and patched. The problem, found thanks to Kevin Littlejohn's efforts, affects those sites which make their Zope management interface available to untrusted users. All Zope users are encouraged to read the announcement and update their Zope installation. Patches are available for both 2.x and 1.x. This patch forced two new Zope releases, 2.1.2 and 1.10.4. http://www.zope.org/Products/Zope/2.1.2/Zope_212_release New Products * Jephte CLAIN has released a new NT Domain authenticator: jcNTUserFolder. Jephte's Product differs from "htrd"'s in that roles are given through the web and impersonation is not used. http://www.zope.org/Members/jephte/jcNTUserFolder Updates * "Drew" updated the Photo Product. Photo resizes images to the user's preferred size. The present version is 0.1.0. http://www.zope.org/Members/Drew/Photo * "vladap" updated the mysqlUserFolder Product. This update fixes a folder creation bug. mysqlUserFolder allows you to authenticate users with data stored in a mysql database. It also allows you to store arbitrary per-user data, and it supports HTTP and cookie-based authentication schemes. The present version is 0.3.2. http://www.zope.org/Members/vladap/mysqlUserFolder * Jephte CLAIN has also released two patches, one to the MIME tag, and one to the import/export system. The MIME patch adds *_expr versions of the type, disposition, encode and name attributes of the MIME tag. These allow you to evaluate an expression for the value of the attribute rather than specifying a literal value. The patch also adds the attributes filename and filename_expr to the tag. These attributes supply hints that the client will use to determine the file's name. The import/export patch allows you to import objects through the web instead of having to place files on the filesystem. http://www.zope.org/Members/jephte/MIMETag http://www.zope.org/Members/jephte/WebImport * "phd" released an update to the mod_pcgi2 package. This update adds a PCGI_ROOT command for virtual hosting. mod_pcgi2 is an Apache module which moves the PCGI client into Apache's address space, preventing the need to start a new process to avoid the "fork tax". The present version is 0.2.0. http://www.zope.org/Members/phd/mod_pcgi2 Zope.org items * "Gregor" had some quibbles with a couple aspects of Zope's user interface. He wrote and submitted a How-To describing how to prevent the "Powered by Zope" link from opening in a frame, and how to make the Zope document editing TEXTAREA soft-wrap. http://www.zope.org/Members/Gregor/misc_nitpicks Notable Discussions * Olivier Deckmyn <olivier.deckmyn(a)mail.dotcom.fr> has just started what stands to be an interesting thread for those wishing to take the first step developing Zope applications. Olivier has a set of classes which implement the logic of the application he wishes to produce. He is looking for advice on how to move from a set of standalone objects to a Zope application. http://lists.zope.org/pipermail/zope/1999-December/016251.html * To ring in the new year, Wei Tao <taow(a)bd748.pku.edu.cn> started a Zope wishlist thread. Got a wish, rant or suggestion? Chime in. http://lists.zope.org/pipermail/zope/2000-January/016318.html * A thread significant to Product developers: Martijn Faassen <m.faassen(a)vet.uu.nl> desires to develop a set of Product standards. He points out that there are some rather arcane things that one has to do to produce a well-behaved Zope Product, but that many people do not know what they are and even those who do know do not always know _why_ ("voodoo programming"). Martijn makes a number of suggestions to rectify this problem. Chris McDonough graciously offers to contribute some effort to the cause. http://lists.zope.org/pipermail/zope-dev/2000-January/002823.html http://lists.zope.org/pipermail/zope-dev/2000-January/002824.html -- Mike Pelletier.

Marcus Mendes writes: > I've got the follow content : Key Error SERVER_NAME, that is, > .... > form= REQUEST.form > .... > server = form['SERVER_NAME'] The error report is unambiguous. Your "REQUEST.form" does not contain "SERVER_NAME". You may try "REQUEST['SERVER_NAME']". Remember: "REQUEST.form" contains just the form variable or parameter definitions in the URL's query string. "REQUEST" contains other information in "REQUEST.cookies", "REQUEST.other" and "REQUEST.environ", all of which are accessible through "REQUEST[...]". "SERVER_NAME" is a CGI variable, defined in "REQUEST.environ". Dieter
