That would work if you have a persistent object you can (and want)
to attach the DA to.

What is the sense? You can not store persistent objects. You might store
a reference to the object using some _v_ variables to avoid getting
the DA everytime through acquisition (this makes only sense
if you have performance issues, do you?).


The sense is that I would like to find an easy way to install my product
without setting up the database connection manually. I guess the way to
do it is to add some code in install.py then ?



huh? Either you expect a DA under a particular ID and use acquisition to 
get hold of it or you except a certain meta_type and use superValues() to 
search for instances of this particular meta_type.
