[Zope] Re: CoreSessionTracking

[Chris McDonough]

Hi Uwe,

If possible, continue to cc the Zope list on this... thanks...

You can explicitly cause a transaction to be committed, but not in DTML or
in a Python Script.  You'll need to use an external method...

Here's an example of an function which does this:

def commit_trans():
    get_transaction().commit()

Make an external method named commit_trans, reference this function from
within the external method UI, and then from dtml, you can do this:

<dtml-call commit_trans>

... right before the raise.  This should save the session data, then it
won't matter if you raise afterwards in the DTML.

HTH,

- C

Hi,

wow - that's a quick answer.
No I don't think that there's another way to do handle loginmanager.
Loginmanager gets called on an authorization exception. The LoginForm isn't
called directly, but gets called on any object a user tries to view without
proper authentication.
I don't know much about ZODB transactions, but probably you know if there's
a
way to finish the old transaction and start a new one ?

Thanks - I'll try to remove the raise.
