I think they are already in the name space when your module is imported into it. You are going under the assumption that your module is the top level entity, it is not. They tell me they don't want to put python code in the object database. Just why should be put on the zope web site.

- DTML Example folder...
by Andy Smith 22 Jan '99

22 Jan '99

Hi All, I've just uploaded a tar file to the contrib area. It contains a Zope folder with a bunch of demos showing how to get started with DTML. It should be useful for newbies to get a feel for how to achieve the 'bare-bones' functionality you might want when creating a site. (Looping, Traversing, Storing Info, Creating Folders etc.). The file untars in the top level zope directory, and has the following files... var/export.bbe - the contents of the folder. Extensions/timesTable.py - An external methods file Extensions/README_DTMLExamples.txt - How to load the folder Comments welcome. Cheers, Andy.

- Extending SQLtest
by David White 22 Jan '99

22 Jan '99

Would it be possible to 'extend' the SQLtest class to be able to dynamically generate more things than just 'in' and '='? I'd like to be able to put the following in int type textboxes: '1-10' will generate the SQL fragment: (column BETWEEN 1 AND 10). '1,3,5-12,17-28,34,37,39' will generate the SQL fragment: ((column IN (1,3,5,34,37,39)) OR (column BETWEEN 5 AND 12) OR (column BETWEEN 17 AND 28)) '> 34' will generate the SQL fragment (note: all numeric comparisons should be available (>,<,>=,<=,!=, etc): (column > 34) In text type textboxes id like to be able to put the following: 'Z%' and have it generate: (column LIKE 'Z%') And finally in date type textboxes I'd like to be able to specify a list or range of dates (similar to the int type above) with the exception that to specify a date range you wouldn't be able to use the '-' character. You could use something like 'to' like this: '01-JAN-1999 to 01-MAR-1999' Note that none of these should be very difficult to implement. I actually have a web based database app (connecting to Oracle and written in Perl) which does all of this (and more). All my queries are dynamically generated using the above rules. I've become VERY interested in Zope as of late and am trying to push for our Apps to be more Product centric and Zope seems heaven-sent, so hence my interest in porting some/all of our apps to Zope Products. Getting everyone else to see that vision is another matter... My question is whether this would be a generally useful addition to SQLtest or if it should be created as an Extension Module?

- Website recommendation
by Kevin Dangoor 22 Jan '99

22 Jan '99

I was speaking with a coworker here yesterday, and he was saying that one advantage that perl has over python is CPAN. He said that there are tons of python modules out there, but you really have to go looking for them. I've seen a few Products that people have put together here and posted on their own websites. I think it would be good to take the contrib area on the Zope site seriously, so that it will grow into a repository as useful as CPAN. To get things going in that direction requires the cooperation of everyone. If DC can keep the contrib area organized as the number of Products increases, and if people make sure they submit their Products to the site, we'll have the beginnings of CZAN :) Kevin -- Kevin Dangoor kid(a)ans.net / 734-214-7349

Jim> I think that XML-RPC would almost certainly be a cool thing to Jim> support in Zope, and Zope would be a cool server for XML RPC. IMO, Jim> the right way to do it would be to add support for it to Jim> ZPublisher. Yes, and Dave Winer would like to see Zope support XML-RPC. I could add it easily to the module I'm currently publishing. I'll see what I can come up with. It's perhaps not what Jim had in mind, but should be easily incorporated into other peoples' servers. Jim> XML-RPC (http://www.scripting.com/frontier5/xml/code/rpc.html) uses Jim> POST requests with content type "text/xml". (Does anyone but me Jim> think that this content type is a bit too broad?) I suspect on the surface it might be. I'm no whiz with HTTP, but XML-RPC requests are supposed to POST to /RPC2: POST /RPC2 HTTP/1.0 Content-type: text/xml ... I think that should serve to distinguish between different uses of text/xml, yes? I noticed with my sample server (the stuff Fredrik Lundh sent me) I am seeing all of POST /RPC2 HTTP/1.0 POST / HTTP/1.0 GET / HTTP/1.0 I'm not inspecting the PATH component at the moment, so the first two both work. The second should get a 404 error since my server only handles XML-RPC requests. The third bombs correctly with a 501 error (method not implemented).

- ANNOUNCE: ExternalLink product
by The Dragon De Monsyne 22 Jan '99

22 Jan '99

Well, I've been having fun poking around Zope, and whilst learning, I came up with a simple,but usefull Zope product, ExternalLink. It's used to represent hyperlink, and is usefull for linklists. It: - can check links - also keeps track of statistics on the remote document (size, mimetype & last modified date) - can count click-thrus - has a facility for batch creation of ExternalLink objects by uploading a simple textfile And it includes a ZPublisher.Client script runnable from a cronjob to automate link checking (when the script runs, it does the actual contacting of the remote server itself to avoid blocking the Zope server) So, get it, use it, love it :> http://www.integral.org/~dragondm/python/ExternalLink.tar.gz -The Dragon De Monsyne

I have not tested if It could be the proxy server, as I have not yet properly set it up on my home computer. some more facts: 1. On my clients computer the switch to Apache 1.3.3 does not make any difference, so I guess it is a pcgi/Bobo problem 2. I use the pcgi info file to set PYTHONUNBUFFERED=1 BTW, does PYTHONUNBUFFERED affect also pcgi-publisher.exe ? 3. I once got an uncomplete response on my home machine as well, it was the first time I accessed the page after startup, i.e. the request that started the Bobo server. So it just _may_ be that it is a performance related issue. Just speculating, but it may happen to other people as well, and they just don't notice, because: a) it does not happen on very short files b) it is usually hard to detect if the end of file is missing I see it each time because the end of file contains a JavaScript function that is invoked using onLoad() and thus each time it is missing IE4.0 shows an alert (in addition to not running the function) ---------- Hannu

- FW: Help with how to do a PUT in Zope
by David Wagle 22 Jan '99

22 Jan '99

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ok. I have a database system that is accessed through Zope. It works great. I want to add a page that allows the users to use simply provide their local path to a html page and it will be uploaded to the server with the 'PUT' protocall. If figure this is doable. Perhaps with some of the code from teh Client.py file. HOWEVER, I can't seem to figure this out. Am I simply misguided here? IF it can be done could someone be kind enough to hack up a simple example? Thanks. Dave ps -- list maintainer: PLEASE do not require RARP on the list.

- Bug? (Overzealous authorization)
by Magnus Lie Hetland 22 Jan '99

22 Jan '99

After a small problem uploading a file, now Zope insists on me supplying a password even for just watching the pages. I have looked at the Anonymous rights, and they are as they have always been... What can I do about this? (These are the times when I wish I could see what was in the DB... Much easier with web pages as text files ;) -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

- How can I get the column names from an SQL Method with DTML?
by Plamen Nikolaev 22 Jan '99

22 Jan '99

Hi everybody, I've been fascinated with Zope for 3 days already (thanks Digital Creations!) and here is my first serious problem: I would like to ease the creation of input forms for inserting data in a database. My plan is to be able to generate a form based on the fields of an already created SQL Method with a "select * from table" statement. My question is: how can I get the column names from the SQL method? I think I noticed that _searchable_result_columns() is used to get this information when creating a Search Interface. Is it possible to get it from DTML without using an External Method? Thanks, Plamen
