A combination of a real import/export facility plus Sessions would perhaps let locking do its work and warn about collisions. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- Z Publisher + Musi-Cal
by skip＠calendar.com 29 Dec '98

29 Dec '98

I wrote a Z Publisher (nee Bobo) module that replaces the CGI script interface to Musi-Cal's database server. It's available for playing/testing at http://www.automatrix.com/~skip/z.html This is a straightforward adaptation of the general search interface available at http://concerts.calendar.com/search.shtml If you try it out and encounter any problems, let me know. BOBO_DEBUG_MODE is set, so any tracebacks generated will be visible. This is a test-only interface, so please don't publicize it outside of the Zope/Bobo community. Performance is fairly impressive. Comparing the following two URLs: http://concerts.calendar.com/cgi-bin/event-search?city=Albany,+NY&keywords=… http://concerts.calendar.com:8080/search?city=Albany,+NY&keywords=acoustic the CGI version averaged 2.6 seconds for ten runs while the Z version averaged 0.6 seconds. The two obvious places to look for the time differences are elimination of the CGI startup time and the performance boost from the new DocumentTemplate code (critical parts written in C and the long-running process's ability to reuse the parsed template). Any questions, comments or bug reports, let me know.

- pcgi, os.environ, and cookies
by BScherer＠mobile.bam.com 29 Dec '98

29 Dec '98

Hi, I've got bobo application that I've converted to run under the pcgi that comes with Zope 1.9 final. The application uses a cookie based authentication/identification scheme. The problem is that the app runnning under pcgi seems to maintain the environment under which it was started, which means that the cookie info never changes. If I start the app as an authenticated user, anybody can get in; if I start it as a non authenticated user, nobody can get in. I've confirmed the static environ by logging it; it never changes. I'm using an old cookie.py module: # by Dave Mitchell (davem(a)magnet.com) 1995 Maybe there is another way to get fresh cookies? Thanks Bill

- additional docs, of builtin modules and _ ?
by Anthony Baxter 29 Dec '98

29 Dec '98

Has any thought gone into extending the HelpSys stuff to also document the contents of _ and the standard builtin modules? I had something to just dump this out back under Principia at my last place of work - I could re-hack this, but it would be much prettier as a component of HelpSys.

- Zope - New MySQLDA breaks connectivity
by Chad Fowler 29 Dec '98

29 Dec '98

My last post ended up being caused by a bug in the MySQL adapter (hence today's patch). While I was delighted to hear that it wasn't my fault, I encountered more bad luck after upgrading to the new adapter. With new or existing MySQL connection objects, I am unable to connect and receive an error that my connection string is invalid. Has anyone else had similar problems? Unfortunately, I'm more experienced with Sybase and Oracle, so I'm not sure if it's just something I've done wrong with MySQL. Before, I was just using: testdb root ...as my connection string. Stupid, maybe, but it was sufficient for learning Zope on my non-production workstation. I've since attempted to create users with valid passwords and use them. I've also done something like the following: testdb@myhost myusername mypassword ...and every conceivable variation of that. I'm at a loss. Thanks in advance, Chad Fowler

- Discovering sub-folders names and proprieties
by Paulo Eduardo Neves 28 Dec '98

28 Dec '98

Hi, I tried Zope last weekend. It's darn coooooool. Let's get Zoped!!! Now my first question in this list: How can I get the subfolders names and proprieties (e.g. title) from DTML? I want to build a navigation bar that would automatically expand when a new subfolder is added. thanks in advance, -- Paulo Eduardo Neves PUC-Rio de Janeiro Pager: Central: 292-4499 cod. 213 99 64 ou use a URL: http://www.learn.fplf.org.br/neves/mensagempager.html

- OK, i"m stupid or.. fsimport
by Christopher G. Petrilli 28 Dec '98

28 Dec '98

OK, I've got directories with a bunch of images in them, so to cram them into the POS, I am using fsimport... so two things: 1) the page says use URL?fsfile=... when it's really URL?fsdir=... no big deal :-) 2) I tworked for the first directory, I think, but I added a test so that it would work, regardless of the case of the extensions in figuring out it's an image... now it doesn't work, even though according to dear old Mr. Creosote, it's passing the _isimg test...

- Re: Re: [Zope] - RESPONSE.headers Help needed
by BScherer＠mobile.bam.com 28 Dec '98

28 Dec '98

I've got some more info that may help solve my problem. I change the hanlder for text/plain from Netscape to 'Save to Disk', and it worked. This prompted me to look more closely at the headers. This is what I found: HTTP/1.1 200 OK Date: Mon, 28 Dec 1998 18:52:25 GMT Server: Apache/1.3.3(Unix) Content-Disposition: inline; filename=salesdat.csv Content-Length: 501 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Content-Type: text/plain <--snip--> This leads me to beleive the Bobo is ignoring or overwriting the content-type line in my code: RESPONSE.headers['Content-Type'] = "text/csv" RESPONSE.headers['Content-Disposition'] = "inline; filename=salesdat.csv" RESPONSE.flush() Have we a bug here?

You could try playing around with JavaScript (perhaps), but that seems (even if it works) like a worse solution than lying.

- USING THE ZOPE OBJECT DATABASE
by Theodore Patrick 28 Dec '98

28 Dec '98

Ok, I have been reading on Object storage and manipulation in Python and there has been a number of threads about attaching databases. WHY? ZOPE IS A DATABASE! If I am not mistaken! (no flames yet...read on) In traditional object storage you create objects(folders in Zope) with properties. Then refer to them. ______________________________ HERE IS MY QUESTION(Q:) AND POINT(P:) Q:CAN ZOPE STORE DATA AS PROPERTIES OF A FOLDER? Q:CAN THIS HAPPEN DYNAMICALLY? (a.Create objects b.Store Form data to objects c.Refer to Objects) P:IF YES: THEN YOU DO NOT NEED A DATABASE(in most/some cases-Depending on the APP)! ______________________________ SCENARIO 1. User Logs on to a site made of ZOPE. 2. User fills out form full of data on the user. FORM DATA=(username=monty,dog=rover,shoes=yes,picture=me.gif) 3. Zope creates a new user record object --> user_recs.monty 4. Zope attaches all of the form data to the object as properties so that: a. user_recs.monty.dog = rover b. user_recs.monty.shoes = yes a. user_recs.monty.picture = me.gif 5. To GET data simply refer to object property and Data Appears. DING! ______________________________ Objects in Zope vs. Objects in Python ??? (OBJECT CREATION, PROPERTY ALLOCATION, AND PERSISTENCE) DO OBJECTS GET CREATED SIMPLY BY SETTING THEM TO A VALUE? IN DTML: user.dogs.fred.john = 1 Have I created a PERSISTENT OBJECT IN ZOPE? Have I created New Folders?ie; [john(property)=1] inside [fred(object-folder)] inside [dogs(object-folder)] inside [user(object-folder)] How would I do this in ZOPE DTML? ______________________________ Thanks and Happy Holidays!
