 Blank datesnumbers are important, I don' t know how they could
 escape us.

 As for nicer interface... I guess you' ll have to elaborate a
 bit ;-)

Well, I think it's manage_changeProperties (nasty name for starters) that
deletes any property you don't include in its arguments, see the interfaces
wiki for details.

How about just replacing it with:

def modifyProperties(**kw)

...where kw is a dictionary mapping property name to property value. If it
property specified in kw didn't exist, it would be created.

Also, on addProperty and modifyProperties, how about making type coersion
happen and raise an exception if it fails?

so, if you did addProperty('test','string',1.234), addProperty would coerse
1.234 into the string '1.234' or raise an UncoercableException if it
couldn't?

Might be nice if the available property types were also documented
somewhere.
Hmm, also, coersion should check that when something is stored as the
'lines' property type, it only accepts a list of strings.

cheers,

Chris

2001-05-28 Thread Zopista

ZWiki's seem a little wonky at the moment so Im commenting here.

The one big that would be hugely helpful is a dict property class. Should be
quite simple and very useful IHMO without having to rely on TinyTables etc.

Cheers and thanks for starting up the project.

Subject: [Zope-dev] What would *you* like to have in PropertyManager and
friends?


 raise
ZopeProject('http://dev.zope.org/Wikis/DevSite/Proposals/PropertyRevamp')

 We at Hiperlogica realize a lot of you people prefer to write
 your code in Python in the filesystem. However, we also believe
 the power of Zope's trough-the-web RAD framework is one of the
 reasons for its success; more importantly, it's a good part of
 the reason it works for *us*.

 In this spirit, we fired up HiperDom a few months ago, and
 we're now working on ZUnitTTW to allow developers to unit test
 their ZClasses and even their very sites.

 Now, we've been taking note of a lot of peeves we have with
 Properties, in the past one year or so. After all this time,
 and dealing with some Zope internals, we feel confident enough
 to propose to fix them.

 So we're raising a Project in the fishbowl to implement these
 changes. But before we dive in the mud, we'd like to hear from
 people that really use Properties (and/or ZClasses), or that
 would use them if they were more powerful. Please go to the
 Proposal page, linked above, and tell us what you think.

 ...and how about a list-of-objects type too?

Hmm what is that? You can have a list already.

Cheers.
