Zope Product Debug Cycle..
by Chui.Tey＠env.qld.gov.au 01 Oct '99

01 Oct '99

My current Zope Product Debug Cycle: Pythonwin: verify no syntax error Start Zope (using start.bat etc) View the traceback on product if product broken Stop Zope. Repeat. This is painfully slow. (akin to bad old days of compile,test, debug, code ...) Is there a better way? I have been experimenting with: Start Zope (using start.bat etc) Start monitor_client Pythonwin: verify no syntax error import/reload Product.myproduct instantiate class try to perform myfolder._setObject(id,instance) View the traceback on product if product broken Check product through browser Repeat. This is somewhat faster. Third option: never tried this... Create classes in Python Then subclass these classes but make them inherit from Zope's classes as well. (Kind of like wrapping my class with Zope) Then pray and debug... Fourth option: Find an existing Zope product which does similar actions (say SQL or whatever) and then see jack hack. hack, jack, hack. This is pretty good because it catches little things like doc strings required for methods to be published et c. (The fourth would be a good one if a cheat sheet is made up and we all can cut and paste) How do the zope experts do their Product development. Is there anyway we can reload a product module when Zope is running? Chui

RE: [Zope] Problem with ZODBCDA-3.1.0b2
by Alexander Staubo 01 Oct '99

Here's a suggestion that I didn't think of earlier: Enable logging in the ODBC Administrator control panel. For example, you might get things like: z2 d2:4f EXIT SQLConnectW with return code -1 (SQL_ERROR) HDBC 0x01306828 WCHAR * 0x01303478 [ 8] "Foobar" SWORD 8 WCHAR * 0x6a9ac284 [ -3] "******\ 0" SWORD -3 WCHAR * 0x6a9ac284 [ -3] "******\ 0" SWORD -3 DIAG [S1000] [Microsoft][ODBC Microsoft Access 97 Driver] Can't open database '(unknown)'. It may not be a database that your application recognizes, or the file may be corrupt. (-1028) ...which is exactly what I'm getting with a certain Access database I'm trying to set up. (A curse on Access! But sometimes that's what a customer wants, alas. A curse on customers!)

ZCatalog searching questions
by Dave Kimmel 01 Oct '99

01 Oct '99

Hello all I'm trying to re-implement the internal policy manual here at work using Zope (it's currently hyperlinked WordPerfect documents), and after demoing it to management there are now two things I need to solve with the search feature. First, is there any way I can search by regular expression or search for part of a word? Specifically, I need to search the content of a bunch of DTML Documents (these only contain the text of the policies and references to standard_html_header and standard_html_footer) for partial word matches. For example, "vac" needs to match "vacation", "vacations", "vaccination", etc. Second, is there any way to use a list of synonyms when searching? For example, a search for "headstone" should also search for "monument" and "gravestone", and likewise a search for "gravestone" should also search for "monument" and "headstone". Am I asking too much of this? Should I be buying a Python book and adding this functionality myself? Should I be using something other than ZCatalog? Should I be using something other than Zope? (Please say no, I happen to like Zope!) Thank you! -- Dave Kimmel Systems Analyst Office of the Public Trustee, Alberta Justice

"Suggestion-let" for Zope 2.0.2 (on Control_Panel/Products interface)
by 이관수 01 Oct '99

01 Oct '99

Control Panel Distribution panel needs to be more verbose than now. Particulary, there should be "Import" button for Products(or some words that if you click "Export" without selecting any installed product you can access usual Import/Export interface) and some cautions for the difference between Product Distribution and Ex/Im-ported Products. Only after "Broken Product" experience and reading Amos's http://www.zope.org/Members/Amos/ControlPanelDistribution, I realized this Sorry, I did not read through the new ZCMG, there might be some explanation. But still some more verboseness seems appropriate. Should I submit this to Collector? But this seems less than "Feature". feeling dumbset in the Zopeland, again, LEE Kwan Soo.

RE: [Zope] manage_addFile() => TypeError

Duh! This code <dtml-call "manage_addFile(rep.this(),'newid',file)"> maps id=rep.this() file='newid' title=file *self* is passed implicitly. I hate it when I waste two days on such stupid mistakes. Zope is great. I am unworthy.

Offline development
by Geoff Caplan 01 Oct '99

01 Oct '99

Hi I would be using Zope in the UK, where dialup or leaseline access to the web is still very expensive. Is it practical to develop and test offline on the local machine before uploading changes to the remote production site? How is this done? Thanks Geoff Caplan

Have a look for Scott's Session product. It's a good base to work from. I'm building an SQL-backed Session object - it works by both setting a cookie, and putting the session-id in the URL (look at a typical Amazon.com URL). It stores the session's persistent data in a SQL database. It's not yet done, but I plan to release it when it is. Anthony

grouping of user-contributed products on zope.org?
by Anthony Baxter 01 Oct '99

01 Oct '99

Has anyone put any thought into producing "categories" of products on zope.org? Right now the one list of products is getting hard to wade through already - organising products into some sort of category system would make this a bit easier... no? yes? Anthony

Session management without cookies
by Geoff Caplan 01 Oct '99

01 Oct '99

Hi My prospective application with Zope would have to test for the ability to wite cookies, and degrade gracefully to cookieless session management if required. On a quick first reading of the documentation, I am not sure if Zope offers any help with this, or would it be a matter of using hidden forms and passing a parameter from page to page? Geoff Caplan

There are no igorant questions :) FastCGI integration with Zope, like the other transport implementations, will be totally transaparent to the developer - the only time you will have to think about it is when you install it.
