Zope Weekly News
by Mike Pelletier 29 Mar '00

29 Mar '00

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the zope-announce mailing list and the Zope.org site. The ZWN is changing days! The next ZWN will be published on Tuesday. Any opinions contained in the Zope Weekly News are those of the chronicler exclusively. Announcements * ZEO will go Open Source ZEO, the commercial Zope scalability option from Digital Creations, will go Open Source. After a trial period in mid-April, it will be available to everyone by mid-May. ZEO (Zope Enterprise Option) turns Zope into a distributed transactional object system, allowing people to add processors, machines, and networks to scale their web applications. More information can be found on the ZEO Product page. http://www.zope.org/Products/ZEO/ * Oracle 8i Setup file, by Chris Petrilli Chris has released his Oracle setup file. This file is used to create the Oracle library. It has been tested internally for a couple of weeks. See Chris's announcement for a caveat. http://www.zope.org/Members/petrilli/Oracle8i * Zope LATEX Math, by Bruno Vernier On his site, Bruno describes how to use LaTeX notation to render mathematical expressions directly from Zope. http://ess.vancouver.bc.ca/zope/math * Users Group - Ohio James Orbin <jorbin33(a)hotmail.com> would like to set up (or would like to participate in) a Zope users group for Ohio. If you are interested, please write James, or see: http://lists.zope.org/pipermail/zope-announce/2000-March/000137.html New Products * Software Product: L10NFolder, by "fog" The author writes, "This is a subclass of the standard folder with some added bonuses. The L10NFolder support localized properties and search paths." http://www.zope.org/Members/fog/l10nfolder Updates * Software Product: XML Document, by Amos Latteier XML Document has been updated to work with Zope 2.1.6. The latest release is 1.0a6. http://www.zope.org/Products/XMLDocument * Software Product: Zope MySQL Database Adapter, by "mordred" "mordred" has released an update to the MySQL Database Adapter, by Michel Pelletier (Portland). This release is 1.1.4, and fixes one bug: - Fixed a bug that caused Zope to fail on selecting aggregate functions such as 'select max(number) from table' * Software Product: ZWiki, by "simon" ZWiki is a Wiki web for Zope. Zope and Wiki are a good combination. Wiki assumes that, in general, users are trustworthy. Zope, with it's security and transaction history, makes it easy to trust users. ZWiki is a sort of anarchic collaborative authoring system. This version, 0.5, streamlines the default pages and UI, and disables the experimental catalog support. This release is intended to be immediately usable out of the box. http://www.zope.org/Members/simon/ZWiki/ Zope.org items * How-To: Changing Base Classes for a ZClass, by "AlexR" When you create a ZClass, you are given an opportunity to chose which classes it will inherit from. Since ZClasses are often used for rapid prototyping, you will not always select the correct classes the first time. It is quite a lot of work to create a new set of classes with the correct bases and to move all the contents into them from the old classes. Armed with this How-To, you will be able to change the base classes of a ZClass in-place! http://www.zope.org/Members/AlexR/ChangingBaseClasses * How-To: Serve PHP/Perl within Zope, by "Mamey" "As you migrate your site to Zope, you may want to embed a previously created PHP or Perl directory tree within Zope. Or perhaps you found a nifty web application that is coded in PHP/Perl and want to serve it within your Zope site." This is a bit more advanced than simply rewriting certain URLs to be served by a different server. This How-To will actually allow you to embed the external content in dynamic Zope pages. http://www.zope.org/Members/Mamey/PHP -- Mike Pelletier.

building/exporting site and server question
by David Eleuterius 29 Mar '00

29 Mar '00

I am relatively new to Zope, and I am working on a personal project at home on my Win98 box. I am just now getting the "zen" of Zope as everyone refers to it, and am building a true functional application. So now that I am getting comfortable with Zope, here is my question. I am wondering if I can build my site/application on my Win98 box at home, export it out and then import it into another Zope installation running on another operating system (either BSDI or Linux). I am thinking I will have to buy my own server so that I can let Zope run as the server itself -- our servers up here all run Apache and I doubt our systems administrator up here would want to take the time and effort required to get that running properly (plus those are production servers, not really for employee projects!). Is it possible and/or recommended to build a site/application on one installation and import it into another? Or should I just go ahead and by a box, put Linux on it, and proceed to build it on that platform? My concern is spending a lot of time building out the site on my home box and then finding a show-stopping hitch in the migration to another platform/installation. Anyone who has had any experience with migrating Zope applications to other platforms/installation please reply so that I can make an informed decision as to how to proceed. And also is there any reason to use Apache instead of letting Zope run as the server itself -- this will be on my own server so I doubt there will be much else on the box then my personal project and my home site (two virtual domains). Thanks in advance.

Mac2ISO conversion?
by Oliver Wrede 29 Mar '00

29 Mar '00

I need to enter text data into a MySQL database via HTML forms. Text entered on a Macintosh client is not ISO-Latin as it seems. When getting that text out of the database, the special characters are broken in the HTML page but not in the textarea. Text entered via a Windows browser are not broken in the Mac browsers HTML page - but in the textarea. So I guess I should care for getting ISO-Latin text from the Mac clients into the database! >From other areas I know this requires a mac-to-iso translation (in both directions (because the text must be editable on Macs). But how can I do this in Zope? I know how to figure out, if it's a Mac-Client -- do I have to create an External method fr this? Oliver .. Oliver Wrede .. owrede(a)khm.de ..

RE: [Zope] Abstract rendering made difficult?
by Brian Lloyd 29 Mar '00

> >> <dtml-call "REQUEST.set('foo', 'index_html')"> > >> <dtml-var foo> > > > <dtml-call "REQUEST.set('foo',index_html)"> > > <dtml-var foo> > > > > looks like it works > > In my case, 'foo' must be a string, and is actually passed in via > a POST (I need it to maintain state in a "wizard" style form). I'm coming in late on this thread, so ignore me if this has already been covered... :) It sounds like what you want is something like the following: # docname is the variable passed in via the POST whose # value is the name of the document to render. We use # _.getattr(this(), docname) to retrieve the needed # document from the current object. Note that we use # the "let" tag instead of REQUEST.set, which is # increasingly considered evil :) <dtml-let theDoc="_.getattr(this(), docname)"> <dtml-var theDoc> </dtml-let> Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Colour in Structured Text?
by Chris Withers 29 Mar '00

29 Mar '00

Can you do colour in structured text? The reason I ask is that I've just found out how great ZWiki Webs are but I'm wondering if there's a shorter way of changing text colour than: <FONT COLOR="#xxxxxx"> </FONT> I'm looking to use a Wiki so a group of people can edit a web of documents and I was hoping that each person could use a different colour. Having to do the colour by hand defeats the simplicity of a Wiki :( Any ideas? Chris

Problem with SQL+Special chars...
by Oliver Wrede 29 Mar '00

29 Mar '00

I am having a problem with HTML entities. I am using Zope to enter and output text into a MySQL Database. When I output the text, it is rendered through my own External Method: <dtml-var "myMthod(myText)"> I tired to write a little subrouting which is supposed to translate special chars in the database into HTML during output. Unfortuneatly the texts are entered on both MacOS and Windows browsers. This unfortunatly makes it difficult: There is no unique ASCII code in the database -- in other words: the same special char may be represented in the database with to character values. First I looked if the <dtml-sqlvar ...> had anything to offer, but that does not seem to be the case. How can I store text in ISO-Latin into the database regardless the Text is entered via a Mac-Browser or a Windows-Browser? Oliver .. Oliver Wrede .. owrede(a)khm.de ..

ZRDB
by Tino Wildenhain 29 Mar '00

29 Mar '00

Hi, browsing thru Shared.DC.ZRDB.Results i found this construct: -------- line 117 ------------ if not name: raise ValueError, 'Empty column name, %s' % name ------------------------------ This looks a bit silly, because if name is empty, %s will be replaced with nothing... Furthermore, would it not be better to provide a generic name for the empty column? Sure, it is difficult to provide such a name who does not collide with others in namespace, but it would be very helpful, if the underlying database-adaptor does not provide full names under certain circumstances, such as ODBC with CenturaSQLBase always returns empty column names to Zope with the count() Operator. Even if used "as" to rename. How about something like: if not name: name='column%d' % i or such? Next there is always some hassle with those 'table.column' columns returning from databases who do not support column renaming. Would it be a way to rename them automatically to something like table_column? Yes, I know there could be a column already beeing called so. But if one knows she can use table.table_column in such circumstances. May be as alias? Regards Tino Wildenhain
