Mirroring to IIS
by Jake LeBeau 10 Jul '00

10 Jul '00

Hello all, I'm attempting to mirror our Zope site to IIS 5.0 on a W2K Server, and am having problems with Netscape Navigator. Because the files have no file extension, Netscape keeps trying to download and save the files to disk, rather than displaying the content as HTML. I've tried several ways of specifying that the MIME content type header coming from the server is "text/html", but nothing alters the behavior of Netscape. Is there anyone else out there who may have had experience with this and would be willing to help? Any advice would be appreciated. Thank you, Jake LeBeau <jlebeau(a)cityofboise.org>

Are you sure, you did write the argument correctly? You know, Zope is case sensitiv. If it is not wrong, then maybe, this is one of the Zope 2.1.6 Z SQL method bugs. Look in the collector (URL:http://classic.zope.org:8080/Collector) for a patch. Dieter

Re: [Zope] Sorting a list

What you see is caused by the following code in "DocumentTemplate.DT_In.InClass.__init__": if has_key('sort'): self.sort=sort=args['sort'] if sort=='sequence-item': self.sort='' This means, "dtml-in sort=sequence-item" does not sort by "sequence-item" but by the complete tuple (key,item). I think, the special treatment of lists of pairs is altogether a slight misfeature. It would probably have been better to use a special "dict" attribute in analogy to the "mapping" attribute to call for the special pair interpretation. 'sequence-item' should then still be the complete item and 'sequence-value' the second pair component. Probably, it is too late by now to change this. Dieter

automatic link adjustment
by Ragnar Beer 10 Jul '00

10 Jul '00

Howdy Zopistas out there! I just ran into some kind of administrative problem: my students are not so willing anymore when it comes to changing links for the third revision of our website. There are about 200 links to change manually and they have my full sympathy. Apart from that this process is quite error-prone and always needs a lot of testing. Is it possible to have automatic link adjustment in Zope if you change an objects name? I mean like in Dreamweaver or whatever website management programm so that it would ask whether to adjust the referring links if you change a page's name? I know we could do the management partly with Dreamweaver and put the files via ftp but whatever sends cleartext passwords is not an option. So ftp is out. Any other way? --Ragnar

RE: [Zope] Trouble compiling ZMySQLDA
by Eric L. Walstad 10 Jul '00

10 Jul '00

Hi Again, Ewald, // I think I'ts a shame information like this isn't in the ZMySQLDA docs. I // think // it's also a bit of a shame that it's so easy (at least for stupid folks // like me :-) // to download an old version of ZMySQLDA from zope.org while installing // version 1.2 // is a piece of cake. If you search the archives for my name (Walstad) you will see a LOT of questions on how to compile the MySQLDA and MySQLDB. I had a really hard time with it. I now have it working nicely and am happy with it on my "hobby" sites (www.walstads.net) However, I am now considering going to PostgreSQL, instead of MySQL, to serve a business site I am working on so I may have even more to learn. If you are going to use your DB for a production site, I would recommend you look into the comparisons between MySQL and PostgreSQL. PostgreSQL may be a better fit for you and getting started with it now may save you some frustration later on. The mailing list archives have a few discussions on the differences and benefits of each DB. As far as poor documentation goes, I feel your pain. If you believe in "No Pain, No Gain" then relax, you are going to gain a lot from the experience. I'm not a masichist, but I am glad I stuck with it. I like the "open sores" (that's what my wife calls it) community as it has no borders and promotes boundless learning. I'm sure everyone on the list has had similar experiences and will help out as "free" time allows. Good luck. Eric.

Testing For Filesize
by Terry Babbey 10 Jul '00

10 Jul '00

I am trying to create a automated drop down list, and here is my code so far: <form NAME="BOOGER"> <SELECT name="myList"> <dtml-in "objectValues(['DTML Document'])"> <OPTION value='<dtml-var id>'><dtml-var title></OPTION> </dtml-in> </SELECT> </form> I would like to be more specific though and only list files of zero byte size. Is this possible?
