K259	Thursday 07 July 2005 3:04:32 am I was going to add an attribute to the article class. We got about 13.000 articles in the database, and when i add this attribute in the admin-interface then Exponential isn't able to do this operation. Exponential fails this task. Does anyone know how I can create this attribute with a script or make this work in another way? L.

K259	Thursday 07 July 2005 3:31:56 am Exponential processes and you can see on the statusbar in the browser that ez is working, but it hangs after a while..I check some articles, Some articles have got this new attribute available, but not all.
Mikael Johansson	Thursday 07 July 2005 3:42:53 am Maybe it is updating the database so that all articles get an empty value for the attribute? Try to extend the timeout (showld be in your vhosts file I think) and let it process? Mikael Johansson, Sweden
K259	Thursday 07 July 2005 4:15:07 am Nope. The eZ team mentioned that I need to write a script to be able to add a new attribute on a class if there are a lot of objects of this article class in the database. Because it's to heavy to process this through the admin-interface when there's thousands of objects in the db.

Frederik Holljen	Friday 08 July 2005 2:14:27 am As long as the process doesn't time out when you run it through your browser you should be ok. We have a script internaly that we use for this that I think you can use as a starting point. I'll ask someone who has it.
