Many thanks Anthony!
That looks like it will work for now...I may specifically handle call that
code just before validate_and_insert calls in the web app, so I don't get
rid of readURL validation in a place where I need it.

Thanks. I updated the Github issue, as there are multiple problems with the
current implementation of the .validate_and_ methods.
For now, you should be able to get around the two issues you observe by
removing the validators:
db.story.titleAsSlug.requires = db.story.readURL.requires = None
Yo
Can do, here's an example:
# DB
db.define_table('story',
Field('title',
length=512,
widget=lambda field, value: SQLFORM.widgets.string.widget(field,
value,
_size=40),
requires=[IS_NOT_
Need to see the fields.

I'm passing all of the fields needed by the compute function. It looks
something like this:

Uh oh...I just removed requires from the computed field and reran my unit
tests, and now validate_and_insert inserts but the computed field isn't
calculated at all! I tried insert and it does the computation.
Is there some reason validate_and_insert would not compute where insert
does?

In terms of implementation, compute is handled in the .insert() method,
which must necessarily run after validation. I suppos
Thanks for the info Anthony! I'll try one of those approaches.
Why is validation run before compute?

As per the docs, they say they are stored in db but not computed on
retrieval. i guess this applies to updates.
Does this calculate_field function does not return a value in some case?
for example total = unit * price may be None if the operation fails because
either unit or price is None or th
Hi Alfonso,
I think the original reason was that sometimes I would end up with a
computed field without a value. Inserts should automatically compute rows,
but for some reason that wasn't happening here.

Hi Chris, why do you use requires IS_NOT_EMPTY in a computed field?, if you
do, you have to supply a value before is computed, isnt it?
