Hi,
i'm wondering if it's possible to add validation based on the field
spec into web2py.
for example, if a field 'text' has length 25, then the field.requires
list should contain the validator IS_LENGTH(25). this might apply to
conditions like unique, non-empty, as well.

Hi rctay,
some of this is done already. In particular in the example you mention
if a "string" field has length=78, you atomtalically get a IS_LENGTH
(78) validators. Similarly a date field gets a IS_DATE() validators,
etc. This does not apply to 'text' because most databases impose no
length contraints on TEXT.
Anyway, I will look into improving this without breaking backward
compatibility.
