You may explicitly pass all parameters: <dtml-if "extAccess(this(),'COM')"> .... This should work. Dieter

how to reload external method?
by Riku Voipio 15 Sep '00

15 Sep '00

How do you reolad an external method that has changed? the only way I hafe found is restarting zope - pretty slow, and I wouldn't want to do on the daytime at our server (versions are rather cool, now I can develop on the production server safely). The only other way I see would be writing bug free code at the first time, which would be rather cool... Is reloading zope _really_ the only way forus mere mortals? -- Riku Voipio riku.voipio(a)tietoenator.com 09-862 60764

Pluggable brains
by gotcha＠swing.be 14 Sep '00

14 Sep '00

Is there a place where pluggable brains mechanism is described ? I am beginning a Zope site project. With the few I have read about pluggable brains, I feel that more info could help me in deciding which part of data has to stay in ZODB and which should go inside RDBM. Thanks.

Re: [Zope] Adding a new property over http

You have at least 2 options: * Look at the object reference (--> zdp.zope.org) for the method that adds a property (probably something like "manage_addProperty"). * You know, you can do it via the management interface. Search the list archives for a message where I outline how to find out how to do something programmatically from the management DTML source. Dieter

> Thanks Albert and Oleg. If I'm honest, while I have become somewhat > familiar with what Albert describes as zope's 'multiple personality > disorder', I can't say I truly understand it. I still don't think I've > got my head around the _['whatever'] syntax. You like that you can use <dtml-var name> both for properties, external methods and DTML objects? If you do, then you probably like that "_['name']" does the same. "_[...]" evaluates '...' (which should yield a string), looks that up in the namespace (giving an object), determines what type it is (external method, DTML object, something callable, something else) and does what usually is right for such an object. This means, it either calls the method/object with appropriate parameters or returns the object itself (if not callable). If you do not like this, you can use "_.getitem(...)". This returns the object itself, without magical type specific handling. I think, the "multiple personality disorder" does not refer to this "_[...]" intelligence but to the fact, that "id" usually is a (parameterless) method but sometimes is an attribute. The "_[...]" and "<dtml-var name>" magic usually hides this disorder, but without the magic, you may get hit by this design flaw. Dieter

Python requires names to start with a letter. You name "7Dlogoicon_gif" starts with a digit. That is the problem. You can use "_.getitem('7Dlogoicon_gif').tag(border = 0)">, instead Dieter
