I would think it would make more sense to use the _before_update callback.
Then you could simply select the records to be updated and add the relevant
fields to the update fields before the update happens. Instead, though, I
would probably just handle it all more explicitly -- before making the

Another problem or symptom is that the computed function need the record
update call to pass all the fields the computed function needs to access
otherwise does not execute.
for example
my record with id =1
{"event":"1","created_by":4,"status":21}

db(db.entities.id==1).update(event="2

during the computation i retieve from auth_membership the user_id

In auth.signature, the "created_by" field has a "default" attribute, which

I'm using web2py version 2.10.3, so in the model I did this:

I've found that one of my models does a conditional check on request

However, when the function is called from the scheduler, there is no HTTP

Thanks for your replies. I guess you are right Anthony, one should handle
unlikely events even if they are normally rare. The site did already does
this for paying bookings, but I did not expect the duplicates on
reservations.
I have now prevented multiple reservations from a single confirm.

In any case, you should probably have some code that prevents double
booking (i.e., the first time you receive a request with the confirmation,
make some change in the session or db that prevents the same order from
being confirmed/fulfilled twice).

Hi,

Add a print statement. You find that the function is being called

Mind that a function that inserts without a form posting is vulnerable

If you're going to be searching based on the difference between date1 and
date2 why not just include the difference in the DB itself with a computed
field? (http://www.web2py.com/book/default/chapter/06#Computed-Fields)
Yes I do not know how to compare dates with datetime fields in a

I suppose there would ideally be some built-in method to express one
type as the other.
Maybe someone knows a way to do it... D
