sorry, i'm sick and really loopy...
let me rephrase ( and this may have changed since last i tested a
while bac )
everything that comes through request.params / submitted to your
pylons app is a string
there are some neat validators that will handle conversions for you,
so everything is seamless / painless
however, lets say that your select field has only these valid ids,
which you know of as constants from your database:
valid_ids= [0,1,2,3,5,8,13,21,34]
but if you choose something like:
valid= formencode.validators.OneOf( valid_ids )
most will be invalid , because this is really what we want:
valid= formencode.validators.OneOf( [ "%s"%i for i in valid_ids] )
so...
enter things like mike's neat validator, which is """A combination of
the Int and OneOf validators with a custom message"""
and now you're able to do
valid= formencode.validators.SelectInt( valid_ids )
