That's great, I'm sure I'll find all sorts of places that's useful now
that I know about it.
Now that I can dynamically build my Fields for my list, I've tried to
go back and put a requirement on them for validation. You can't use
keywords in a list so I'm a little stumped.
Is there a suggestion for editing this code to insert 'requires'
statements? Or possibly can I just set one global requires? In my
case all values are INTS in the same range.
----
for item in list:
fields.append(Field(item))
form=SQLFORM.factory(*[fields[num] for num in range(len(fields))])
----
If the 'requires' statement didn't have to go IN the field statement I
was thinking the ** notation with a keyword of 'requires' and a value
of 'IS_INT_IN_RANGE(0,100)' might help, but it's got to go IN the Field
(item) statement not just appended to the list after it.
Any suggestions?
