Hi,
In my application whenever I issue a rollback on 'sub-transaction' I
see (using logging.debug) that my main list is being reloaded from the
database.
In other words I do things like this:
- get application wide db session
- load the list of all the drinks
- begin_nested
- create/edit e.g. purchase item of one drink
- commit
- begin_nested
- create/edit another purchase item of the same drink as above
- rollback
- commit (to finally commit first purchase)
At this point all the drinks with all the relations etc are reloaded
from the database.
I tried with expire_on_commit but it doesn't seem to affect rollback.
Is there way to suppress the reloading of all the items and only load
the one affected by the changes by using expire(instance) or
refresh(instance)?
Werner
