Manuele,
May I ask you how you did it?
First of all consider to define a function that returns a unique result
starting from your fields in the uniques list. If theese fields are all
integer (such as id of external references) you can simply append them
in a string following always the same order or if they are string you
car create a dictionary with the field names and values and transform it
in a string that will be unique. Let's call it getUnique().
def getUnique(**kwargs):
...
return out
now add this 'myid' field to your table as in the example below:
db.define_table('mytable',
Field('field1', ...),
Field('field2', ...),
...
Field('myid', length=256, unique=True,
compute=lambda r: getUnique(
**dict([(x, r[x]) for x in (field2, field3, ..., )])
)
I hope I've been clear
bye
Manuele
