Sorry, to finish up some considerations...
Ive been investigating how web2py assigns default validators to field
types.
If im not wrong this is done by SQLFORM which imports a function from
gluon.dal called _default_validators.
In this function the relationship between web2py field types and validators
is hardcoded.
Its a shame that these relationships cannot be extended since it looks like
creating a new field type, is as easy as something like:
db._adapter.types['booleantri']='TINYINT(1)'
I have tried it and
Field("with_kids", "booleantri", requires=IS_NULL_OR(IS_INT_IN_RANGE(0,2)))
works as expected so far.
Of course it might not be this obvious to create a field type (or maybe it
is) but the point is that it would be great if we could declare a default
validator for this sort of custom field types.
I guess that with some python surgery it can be done by overloading this
_default_validators function but yes, it would be great if there were a way
without hacking.
Thanks
