[SQLObject] Custom Validator (unique-ness)

[Sidnei da S. <si...@pl...>]

Howdy,

I was just looking at the new validator stuff, and trying to figure
out how to do something:

I need to have a constraint on one field that the field value is
unique, but this field cannot be a primary key. So, I was thinking
about giving it a Unique validator.

Questions:

  - It seems like the easier way to do this would be to use the
  Wrapper validator, passing a callable that tests for uniqueness of a
  column. Sounds right?

  - Can I put the Unique class (that tests for uniqueness given a
  column name) on the include/Validators.py module?
