New versions of a product
by Robert Leftwich 27 Apr '99

27 Apr '99

What is the best strategy to use when upgrading to a new version of a Zope Product that is already in production and has significant amounts of data in it? The issues are : 1. Modified hierarchy of objects 2. New classes/objects - not a problem as they don't exist in the earlier version. 3. Deleted classes/objects (i.e. no longer required) 4. Renamed classes/objects 5. New methods/attributes - not a problem as they don't exist in the earlier version. 6. Deleted methods/attributes (i.e. no longer required) 7. Renamed methods/attributes Robert Leftwich

I want to stream data through an external method.
by Jay, Dylan 27 Apr '99

27 Apr '99

What I have is several large files for downloading that I don't want to put inside BoboPOS as importing them seems to take forever. It is also more convienient if they exist outside the OODB. So what I want to do is for the user to dl the file through Zope. I have the following external method that works def serveFile(self, file, RESPONSE): RESPONSE.setHeader('Content-type', 'application/x-msdownload') dl_name = "C:/Provision/downloads/"+file dl_file = open(dl_name,'rb') retval = dl_file.read() dl_file.close() return retval However I think this is quite inefficient and will probably not work when large number of users attempt to download the same file at the same time. Anyone have a better solution?

Authentication with ie5 and zope.
by Jay, Dylan 27 Apr '99

27 Apr '99

Has anyone found a solution to basic authentication with ie5 and iis4.0. This is HUGE problem for me as my site has to go live in less than a week and it relies on have users authenticate themselves through the UserDB package. If they can't use ie5.0 to do this, then I have a big problem.

RE: [Zope] Has anyone tried to make Zope invisible using IIS
by Jay, Dylan 27 Apr '99

27 Apr '99

I tried using the isapi filter and it only sort of works. Any links of the first page use the original address not the one that was filtered. What I would like is for it to be completely transparent ie all links point to the virtual directory not the exe file. I assume this doesn't work because of the BASE tag that zope puts in the header. It also won't work because of my use of BASE0..n tags etc. How can these problems be overcome? > -----Original Message----- > From: Brian Lloyd [mailto:Brian@digicool.com] > Sent: Thursday, 15 April 1999 23:58 > To: 'Jay, Dylan'; 'zope(a)zope.org' > Subject: RE: [Zope] Has anyone tried to make Zope invisible using IIS > > > > I basically want to make a virtual directory that points to > > everything on > > the other side of the PCGI exe file however stupid IIS seems > > to be only able > > to make a real directory a virtual directory.

Re: [Zope] [off topic] question?

Well, there are a dozen of fine languages older than Java. What happened is that Java caught the attention of the big media because of the responsivity of web applets in HotJava, the first java-enabled web browser. Java was the first language to be "known" by Wall Street before it was known to programmers. The name of the language, "java", was aptly chosen, too. BB

Me again, sorry for the trouble!
by Tom Deprez 26 Apr '99

Hi, Yep, me again, that pesky person with it's dumb questions. Sorry, about these questions, but I want to know everything and because nobody around me knows something of this stuff, I've to ask you... hope you don't mind too much. If you do, please say! Ok, reading the docs and getting your explenations I see that the choice of database (relational or object oriented) depends on the sort of data to store. Well, I don't get this fully... Suppose we've this data to store : Examination table : Examination, Rooms, FieldX, FieldY, FieldZ Rooms Table: Room, Equipements, FieldX, Subexams SubExams Table: .. .. .. This can be be put in a relational table : Examinations : Exa1, Room1, a, b, c Exa1, Room2, c, d, e Exa2, Room1, d, d, d ... But also can be put in a object-oriented way : Exa1 Room1 a b c Room2 c d e Exa2 Room1 d d d .... So what is the best choice???? Tom.

Zope!
by Tom Deprez 26 Apr '99

26 Apr '99

Hi all, Yep, I finally started writing an article about Zope.... I hope, some of you are willing to read/correct it. Oops, I almost forgot: Question to the creators of Zope. May I write an article about Zope? Hope I may. Writing about web-applications. Does somebody has good documentation on these? i.e. what is a web-application etc. At the moment I'm writing down my own thoughts. And last thing. Can we classify Active Server Pages of M$ as a web-application platform? I though so. Regards, Tom.
