While I'll never rule out the possibility that I'm doing something wrong, every time I've tried just "manage_changeProperties" for ZClass instance, nothing happens. When I do "propertysheets.Whatever.manage_changePropertes" it works just fine... So, AFAIK, yes. That's the way to go for changing properties on a ZClass instance.

To use manage_changeProperties with a ZClass, you need to call the method on the propertysheet itself... like: <dtml-call "propertysheets.properties.manage_changeProperties({'Drafted' : _.getattr(AllPlayers,'draft_round')})"> I believe the reason that you're not seeing the changed property in the cloned object is that you are trying to clone in the same transaction. Therefore, the changed to the Drafted property has not actually been committed yet. The easiest thing to do might be to do a changeProperties on the new object after cloning. Or maybe it's possible to write an external method to commit the transaction (I don't know much about the transaction machinery though). Good luck! Kevin

ZClass wierdness
by Cayce Ullman 12 Oct '99

12 Oct '99

I've been experimenting with Zope, for a few days now. I have been writing a fantasy basketball tracking site for a friend of mine. I am having a few problems with Zclasses. I am trying to change a property of a ZClass then clone it. Everything works, except the cloned copy does not have the latest changed value. Here is my code :  <dtml-with "_.getattr(AllPlayers,player)"> <dtml-call "setAttr('Drafted',_.getattr(AllPlayers,'draft_round'))"> </dtml-with> <dtml-with "_.getattr(Teams,AUTHENTICATED_USER.getUserName())"> <dtml-call "manage_clone(_.getattr(AllPlayers,player),_['player'], REQUEST)"> </dtml-with>  The setAttr method is an external method I wrote for setting attributes, since I can't seem to get the manage_changeProperties to work for a ZClass. (I've heard others are having the same problem) The Drafted property is set on the original object and unset on the cloned one. I can't figure this out.

ZClass and ZCatalog
by Kam Cheung 12 Oct '99

12 Oct '99

I created a ZClass which is inherited from CatalogAware & Object Manager, it's structure is like this: MyClass bodycopy_html index_html Propertysheets Basic ClassName Now, if I find this object using a ZCatalog object, bodycopy_html will become a separate object. This is not what I want, I want the content of bodycopy_html to be indexed as part of a MyClass object. What I am doing now is to hack it on the report, link the result to the MyClass object instead of the bodycopy_html whenever data_record_id_'s parent is a MyClass object. However, is there a better way of handling this? What a ZCatalog looks for when it indexes an object? Does it call a specific method on that object? Can I override it? Kam

Using string.split() on a DTML method
by Jim Cain 12 Oct '99

12 Oct '99

I have a DTML method, category_list_cookie, which returns a string of colon-separated values I use elsewhere. I would like to split this into a list so I can use something like phred.count('whatever') to see if this value is present. However, when I do something like: <dtml-with "_.namespace(var1=_.string.split(category_list_cookie, ':'))"> I get this error: Error Type: TypeError Error Value: argument 1: expected read-only character buffer, ImplicitAcquirerWrapper found Even with something like this: <dtml-with "_.namespace(var1=category_list_cookie)"> <dtml-call "REQUEST.set('var2', _.string.split(var1, ':'))"> the split method gives the same error. Is var1 in the second example merely a reference to category_list_cookie, so that I get the same error? Whether or not this is the case, what does the error mean and how do I fix it? Cheers, Jim
