I'm having trouble getting a custom validator to work with the crud
form. Is the is the correct implementation?
def f(form):
#if form.vars.id == form.vars.myfield:
form.errors.myfield = 'cannot be same as id'
...
form = crud.update(db.mytable,myrecord,onvalidation=f)
...
The form still works fine, but this doesn't ever display an error
message even if i remove the if statement in the validator. Are
custom validators done differently for CRUD and SQLFORM forms?
Thanks!
