This can be emulated in Python by the boolean logic: ( ({conditional expression}) and {TRUE val} ) or {FALSE val} e.g. a = ( ( (x > 1) and "biggerthanone" ) or "smallerthanone" ) >>> x = 0 >>> a = ( (x > 1) and "biggerthanone" ) or "smallerthanone" >>> a 'smallerthanone' > > Or one can embed a fcn call within an argument list in order > to supply a > needed function parameter. Hrm.. I *think* this will work as a function argment. Sure.. why not?

brain hurts regarding dynamic fcn args in Python
by Jeff Sasmor 19 Jun '00

19 Jun '00

Hi- I guess I'm somewhere past a 'newbie' (after a few solid months) and I'm developing a calendar-based (but not based on calendar tag) 'event-log' 'black-box app' for lack of a better term, for eventual relase to Zope.org, if only as a helper for _new_ newbies. I'm stuck on what I guess is a pythonish thing and my brain hurts. Is there a (straightforward?) way to dynamically compose function argument lists? For example, in C, you can write" f(arg1, arg2, (conditional expression)?(val for TRUE state):(val for FALSE state)). Or one can embed a fcn call within an argument list in order to supply a needed function parameter. In my case here in Zope, sometimes I have to search a ZCatalog prior to displaying the results in a <dtml-in> looping construct. <dtml-in "Catalog.searchResults(meta_type='EventDoc',event_date=[first,last],event_date_usage='range:min:max',sort_on='event_date ')"> .... </dtml-in> Now if the 'moderated' property is active I want to add the keyword arg reviewed='on' to the arg list at the time that the searchResults method is invoked. Since this invokation is in an expression it's certainly a python thing, but I can't find any reference to this type of capability in any reference I have. Did I miss something or is there just no simple way to do this? The only way I can see to do it is to wrap Catalog.searchResults() in an external method with some ifs and elifs. TIA.

Internationalization
by Dan Rusch 19 Jun '00

19 Jun '00

How are my fellow Zopers handling Internationalization, especially text. We have a site that is composed of several hunderd pages. We don't use classes but we have made heavy use of aquistion though. For example we have one back button that is aquired thoughout the site etc etc. Basically if the functionality (or code) is used in more than one place it has been but into a method and aquired. Any thoughts or hints? thanks, DR

Need to use a 'date' data type in sqltest
by Jones, David H 19 Jun '00

19 Jun '00

I need to include a test of a date in a DTML variable referenced in a sqltest tag in ZSQL. From reading documentation and testing, it does not appear that the 'date' data type is supported. Can anyone confirm/infirm this and suggest a solution/workaround? Regards, David H.

RE: [Zope] ZOBD caching products?
by Chris McDonough 19 Jun '00

19 Jun '00

This is a 'feature' of the product initialization process. Note that I am just documenting buginess here, I should try to fix this when possible. When a Product can't be initialized (a syntax error, a bad import, whatever), sometimes it will revert back to the state at which it wrote a good *.pyc file and continue along its merry way without giving you any indication there is a problem. Two things: Turn on the STUPID_LOG_FILE. Its contents will show you problems during problem initialization. See http://www.zope.org/Documentation/Misc/LOGGING.txt for more info. Scan the mail list archives for STUPID if this howto doesn't suit you (seriously!) When you really, truly want to refresh a product, delete the product from the control_panel and restart. I *think* that updating version.txt in the product folder has the same effect. > -----Original Message----- > From: Seb Bacon [mailto:seb.bacon@razorfish.co.uk] > Sent: Monday, June 19, 2000 1:57 PM > To: zope(a)zope.org > Subject: [Zope] ZOBD caching products? > > > Ladies and gentlemen, > > Some time ago I wrote to the list to ask for help on a > product reloading > issue.

ZOBD caching products?
by Seb Bacon 19 Jun '00

19 Jun '00

Ladies and gentlemen, Some time ago I wrote to the list to ask for help on a product reloading issue. I'm still banging my head against it now, so i'm restating the problem again in the hope someone can help: I have a very simple product (and it works!) Any changes I make don't get reflected in the product, so... 1) I change the function name in order to break it on purpose 2) I stop and restart Zope (or use the refresh product) ...and... 3) Zope thinks the product still works ?!?!£?"$"" This behaviour exhibits itself in Zope 2.1.6 *and* 2.2.0. Since no-one else ever seems to have had this problem, I can only assume I am doing something wrong at a "doh!" basic level. Sounds to me like the product is getting cached in the ZOBD. I'm only a poor newbie, so I don't really know where to go from here in order to debug the problem. Any clues???? Thanks, Seb.

Textarea Limits (slightly off topic)
by Joshua Brauer 19 Jun '00

19 Jun '00

I'm running into a limit to the amount of text that IE 5 will display on the Macintosh. I am wondering if this is true of all browsers and platforms or unique to IE5/Mac. This of course limits the size of documents that can be edited through the manage interface. Now I really wish Pike worked as an editor without it's problems with > signs.
