Using something like: http://www.zope.org/Members/srichter/Products/DBObjects http://sf.net/projects/modeling But reading the first one has given me a gread headache. It's a complex topic. Well from what I read from DBOBjects, it seems to be convenient to have a trace of the object in the zodb. You put the database adapter on the Openflow, and it regenerates the object structure. Then, you work transparently. One point would be: if you delete the openflow, the objects would not be deleted from the database. If you replace the openflow with and upgrade, it will still use the objects on the database, and will not alterate them. This is: even if there is a trace of the objects of the Zodb, funcionally the datas are completly outside, in the database. From=20the second reading, http://sf.net/projects/modeling, it has been to fast, so no idea :-) Well, I don't know, maybe a simpler solution would be possible, but, how would you attach a property to an instance ? All seem to point to something like this. Just ideas, for the future :-) --=20 __o _ \<_ (_)/(_) Saludos de Juli=E1n -.- DVD-record Tools for linux http://www.freesoftware.fsf.org/dvdrtools/ |
