Hello,
I'm trying to validate a list:string field with is_alphanumeric and
is_length - trying to ensure that names are no longer than 6 alphanumeric
characters in length. (I'm running web2py 2.8.1 in ubuntu 12.04)
view:
<li>Sample name *: {{=form.custom.widget.sample_name}}</li>
controller:
form = SQLFORM(db.register,fields=[..,'sample_name',...])
if form.validate(onvalidation=validate_sample_name):
form.vars.id = db.register.insert(**dict(form.vars))
response.flash = 'Reg saved.'
redirect(URL('samples', 'default', 'index'))
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
model:
db.define_table(
"register",
.....
Field('sample_name','list:string'),
)
def validate_sample_name(form):
for sample in form.vars.sample_name:
out,ers = IS_ALPHANUMERIC()(sample) and
IS_LENGTH(maxsize=6)('sample')
if ers:
form.errors.sample_name = ers
The above does check for alphanumeric characters but doesn't seem to check
for the length of each sample name.
Am I doing something wrong?
Many thanks.
