I am trying to create a short validator that limits the number of children
that can be listed under one parent but I'm having a problem with the
highlighted line because I cant use *parent.id *to specify the selected
parent when the parent variable is referenced outside the validator
function. I rightfully get:
*<type 'exceptions.NameError'> global name 'parent' is not defined*
Anyone on ideas on how to work around this?
def my_validator(form):
* if db((db.children.id>0) & (db.children.parent==parent.id)).count()
>=10:*
form.errors.children_names=SPAN("The number of children has
exceeded the required number")
def registration():
* parent=db.parent(request.args(0, cast=int)) #referenced outside the
validator function*
db.children.parent.default=parent.id
form=SQLFORM(db.children)
if form.process(onvalidation=my_validator).accepted:
response.flash=T('Client Registered')
return locals()
