Yes, you are right.
Thank you massimo
P.S. I love web2py!

The next logical step is creating, reading, updating, and deleting
other records from within the transaction, at which point the lambda
which is really a function, should not be stuck under the field=...
since it is now much more than a field.
Since the lambda is passed the entire record, perhaps
It is worth a try. I can help with debugging but have no time for

The more I think about this the more I like your solution.
We can provide both notations:
1) row.update_record(count=db.table.count+1)
2) row.update_record(count=lambda r: r.count+1)
and the lambda notation should work even without GAE.
If you send me the patch for GAE I can fix the non-gae.
perhaps it is time to again to run web2py to jython! who wants to
take the lead on this?

In trunk. See if it works as you suggested.

Nice, thats great syntax for incrementing counters, but you would need
a lambda to do anything more complicated than arithmetic in a
transaction.
What about a more complex transaction like read a value and set it
based on rules (for creating a lock)?
t2.create() already has onaccept= (it should have been called
onsave= ) because it does not get called until after the record has
been created/updated within the form. You are right oncreate/onupdate
could be replaced with onsave, which does not need to be passed to the
SQLFORM.
Ideally, it shou

I think we have something like this without introducing a special
syntax for GAE based on lambda. In fact on non-gae you can now do
row.update_record(count=db.table.count+1)
The same could work on GAE with your code below.

I can see the use for onaccept but why oncreate/onupdate. This would
be equivalent to putting the code after accepts(..) returns. Am I
missing something?

SQLFORM.accepts(...) could use hooks: onaccept, oncreate, onupdate.
onaccept: called after FORM.accept and immediately before create() or
insert()
oncreate: called after create()
onupdate: callled after update()
These hooks could be used by t2 and passed to SQLFORM:
t2.update(onaccept=...,onupda

This is bad UI to present people with pages to which they don't have

To perform certain actions on GAE you need transactions, eg.
atomically increment a counter.
This is what it would look like:

The GAE driver would check attributes for lambdas and invoke a
transaction when a lambda is present, the other SQL drivers c

Hi Massimo,
I don't think that the sharplus guys would like to distribute their

If the are app specific I would put them in a model file.
I was not planning to extend the number of built-in validators but you
raised a good issue. I think we need one more or one more parameter
for IS_IN_DB.

Ok,
It seems that the version of sqlite shipped with Python versions 2.5
to 3.0 for Windows has been compiled in a way as to not include what
the sqlite guys call the ICU extension. The ICU is a little extension
that links sqlite with the ICU library (installed separately), thus
allowing it to pr
There has been a lot of discussion on HTML helpers. I think their main
shortcoming is actually that for novice web2py users it's hard to find
'the right amount' of them. Some tend to avoid them like yourself and
deprive themselves of some rapid prototyping/design options, while
some people overuse

Thank you, Massimo, it works fine
But, if I want to put these codes in the right files, which files
should I use and which imports should I do ?
have you as a project to expand the list of validators or to make the
