Hi! I solved (partially) my problem: very thanks.

I studied acquisition and then I understood your example.

I've another problem (the last, I hope): I call some ZSQLMethod from Python scripts so I need to execute a command dynamically. example I need to execute 'container.include.sql.%s.getX()' % container.REQUEST.SESSION['dbconn']

but 'exec' is not allowed. Does exist another way or I have to write: if container.REQUEST.SESSION['dbconn'] == 'conn1': container.include.sql.conn1.getX() elif container.REQUEST.SESSION['dbconn'] == 'conn2': container.include.sql.conn2.getX() elif ...

?

In ZPT pages I use python:path('python:container.%s.getX()' % var) without problem but I don't knoe how do the same thing in a script python.

Well, thats just python - I'd suggest skimming thru the python tutorial at python.org at least. You reach objects by getattr(parent,attributename) And in Zope also via: parent[attributename] This should get you going I think. Regards Tino
