Massimiliano Bariola	Friday 13 January 2006 8:47:22 am hi, a question which I think is rather staple but never tried it before: Let's assume I have a large numbers of objects of a certain class (say 1500). then I need to add a new attribute to this class. As far as I know, all __old__ objects get this new attribute, but it is not initialized to any "default value". Instead, the default value is dependent on the attribute's datatype. Question: how do I set the default value for the new attribute in all old objects ? PHP script? some kind of (infernal :-) ) workflow? admin functionality that I don't know ? an unknown eZ update script? Any ideas? :-) TIA, M.B.
Norman Leutner	Sunday 15 January 2006 1:23:43 am I would write a small extension which updates all you class objects. All the script has to do is: 1. Create new object version 2. Store that version 3. Publish the new object version Mit freundlichen Grüßen Best regards Norman Leutner ____________________________________________________________ eZ Publish Platinum Partner - http://www.all2e.com http://ez.no/partners/worldwide_partners/all2e_gmbh

hi,

a question which I think is rather staple but never tried it before:

Let's assume I have a large numbers of objects of a certain class (say 1500). then I need to add a new attribute to this class.

As far as I know, all __old__ objects get this new attribute, but it is not initialized to any "default value". Instead, the default value is dependent on the attribute's datatype.

Question: how do I set the default value for the new attribute in all old objects ?

PHP script?
some kind of (infernal :-) ) workflow?
admin functionality that I don't know ?
an unknown eZ update script?
Any ideas? :-)

TIA,

M.B.

I would write a small extension which updates all you class objects.

All the script has to do is:

1. Create new object version
2. Store that version
3. Publish the new object version

Mit freundlichen Grüßen
