Hi list! :) I am just playing around with Ape (very cool, btw :) and wondering how it can be used from the outside, e.g. not controlled by transactions. Main idea is to manually copy parts of the ZODB to the filesystem (from a product). I first tried the transaction based process, as I found it in some tests: # init (createMapper imported from fsmapper) root_mapper, conns = createMapper(fspath) conn=conns['fs'] resource = StaticResource(root_mapper) storage = ApeStorage(resource, conns) db = ApeDB(storage, resource) get_transaction().begin() # test object to store object = getattr(self,'standard_template.pt') c=db.open() app=c.root()['Application'] id=object.getId() app._setObject(id,object.aq_base,set_owner=0) get_transaction().commit() db.close() which actually stores it but does not seem to me that clean because of all the transaction stuff. I would here then recursively run through all the objects and do that inside one transaction. I then detected the fascades in io.py which I tried to use (dunno if they're thought to be used for such a purpose actually ;-): root_mapper, conns = createMapper(fspath) ei=ExportImport(root_mapper,conns) ei.exportObject(object) Unfortunately this results in an exception Type: MappingError Error Value: Path keychains require a name So can maybe somebody point me to the easiest way to serialize an object using the fsmapper (Shane? ;-) ? I am also interested in reading a serialized object from the fs again and writing it to the fs. Also I wonder if I need to delete objects which have been modified before another export or if there's a possibility to just change it). (and the best would be of course some simple methods for reading/writing a whole directory recursively. I don't know if something like this is already in there somehow or how it works internally.. seems all a bit magic to me ;-) So thanks in advance if anybody can help me :) cheers, Christian -- COM.lounge http://comlounge.net/ communication & design info@comlounge.net
