[Zope] custom_persist_obj
Hi, I am new to Zope and not a programmer. It is a little bit complex for me. I am very frustrated, as I can not find the solution for a pretty simple task: I would like to have persistent object with dictionaries. I think I do not need a ZClass or Product, just a simple object for holding mutable and persistent dictionaries (Manipulating with Script). Like MyObject: dict1 = [ a:1, b:1, c:1, ...] dict2 = [ a:2, d:4, e:6] etc. Thanks for your help in advance, Tamas ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

But that needn't be complex. http://www.zope.org/Members/maxm/HowTo/minimal_01 -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] custom_persist_obj
You have a built-in Zope object for this : PersistentMapping.
dict1=PersistentMapping({'a':1,'b':1,'c':1, ...})
dict1=PersistentMapping({'a':2,'d':4,'e':6})
The only thing you can not do compared to dictionaries is :
for key in dict1:
do something
(you need to use for key in dict1.keys():...)

Re: [Zope] custom_persist_obj
Well, sure. But you need to write some unrestricted (i.e.
filesystem-based) code if you want to create instanced of
PersistentMapping and the like.
by the way, if it's ever going to get large, you might look
into using OOBTree instead of PersistentMapping.
