Re: [Zope] Base ZClass propertysheet management

2000-10-06 Thread Jim Washington 

Hi, Seb

Go to the "Views" tab of the ProductItem ZClass.  You should be able to
add another tab referring to propertysheets/Picture/manage.  This has
worked for me in a similar situation.

RE: [Zope] Base ZClass propertysheet management

2000-10-06 Thread Seb Bacon 

Thanks,

I'll rephrase it using my real life problem:

I have a Picture class, which comprises image, title, description, etc.
I also have a ProductItem class, which subclasses Picture to include a
price, etc.

So finally I have got a ProductItem class, which has a title, image, price,
...

I can access properties inherited from the Picture no problem.  The problem
is that the default management screen for editing the properties of
ProductItem, propertysheets/Details/manage, only provides a means of editing
the unique properties of ProductItem.  Is there a means of managing all the
properties of a ZClass, including those of its parent class?  Or do I have
to code my own management screen to do this?  And if so, what is the correct
way of refering to these properties in DTML?

Feeling a bit dumb...cheers,

Seb

Re: [Zope] Base ZClass propertysheet management

2000-10-06 Thread knight 

Either I don't fully understand your question, or I'm misinterpreting what
you are trying to accomplish.

If you are subclassing A, calling it B, then it _already_ has the
properties of A when it was subclassed. However, if you have two instances
running, one A, and one subclass of A called B, then you can not access
that data in A from B since they are seperate instances.

Maybe you could clarify what you are trying to accomplish (example
maybe)...

Knight
