Thanks David and Anthony:
1- I will reorder validtors for final example, most common ones first.
2- Good suggestion:
I'll try to write a web2pyslices, I like that site a lot as it can
offer
more complete solutions than these discussions often do.
2- A validator?
*Question:*
Would it be worth considering an actual validator for username and
user-like fields.
*IS_LIKE_GOOGLE*
IS_LIKE_GOOGLE validator enforces a username policy similar to Google
Accounts (as of 2012),
min 6 - 30 characters, only letters (a-z) and numbers (0-9), and periods,
can't start or end with a period,
can't have consecutive periods, and of course can't exist in database.
Note: if an optional
IS_LIKE_GOOGLE(db, 'table.fieldname') - then any user created user type
field would be validated,
Cheers,
Today,
I'm going to work on "bad words" in username feature, this should complete
my example.
Rob
