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.

Re: [Zope] custom_persist_obj
Thanks! I am going to try the simpler one first. But I think to be able to create a simple product is also a must. So I will try both.

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():...)

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
