Re: [Zope] manipulating zodb from independent database connection
Thanks Paul and Stefan,
I will look into learning ZEO.
I wish somebody would write a new book on the latest zope releases. I
think Zope is ready for a resurge in interest. Maybe it already is
happening.
Grok...eggificationREST + AJAX architectures.the growing
interest in web services (just what is google doing with zope?).
There are lots of reasons to be getting into zope these days.

I'd like these newly inserted objects to be Zpublishable as well.
To access the ZODB from separate processes you have to run ZEO.

[Zope] manipulating zodb from independent database connection
Does anybody have a script available that shows how to insert objects
into the ZODB root['Application'] from a non-zope process outside the
Zope application? Everytime I try to read root['Application'] I get a
page template error.
I'm using zope 2.5 (matches a book I like) and doing like so:
from ZODB import FileStorage, DB
storage = FileStorage.FileStorage('Data.fs')
db = DB(storage)
connection = db.open()
root = connection.root()

You can do whatever you like, but you're not likely to find many
people still running 2.5 on this list... so you might get less useful
help than you would like.
and doing like so:
from ZODB import FileStorage, DB
storage = FileStorage.FileStorage('Data.fs')
db = DB(storage)
connection = db.open()
root = connection.root()

Not with FileStorage. Only one process at a time can open a
FileStorage.
If you would use ZEO instead, then it would be possible. Your code
above would then be modified to use ClientStorage instead of
FileStorage. But I don't know exactly what the code would look like
in zope 2.5, I haven't run that version in years. I vaguely remember
needing a custom_zodb.py file to set up ClientStorage. If you would
upgrade to a more recent Zope (2.7 or later), then ZEO is available
out of the box just by uncommenting some lines in the example
zope.conf. And you would also get a script at bin/zopectl that's
perfect for this kind of job. Your own script would be invoked as an
argument to zopectl, like:
./bin/zopectl run path/to/my/script
... and you would get the root application automatically set up for
you and bound as app.
But you still need to use ZEO.
