I'm doing the following:
if form.accepts(request.vars,session,onvalidation=my_val):
session.flash='success'
redirect(URL(r=request,f='newpage'))
elif form.errors:
response.flash='error'
I'm wondering if the data are committed to the db before my_val gets
executed or only afterwards? In other words, if my_val does a db
query, will it find already in the db the data from the form?
If no, what if the form acceptance depends on checking the interaction
between the data already in the db and data on the form?
In essence, I want to write the form data to the db, run an algo, then
decide whether to rollback the db. I think I'm really close to the
answer, but I'm not sure what the right way is to do this. Anyone have
a simple example?
