Validates Uniqueness (discussion)

[mattconnolly]

Validates uniqueness appears to work, although:

1. You need to validate the encrypted_* field which doesn't match up with form fields for display to user; and
2. shoulda-matcher validates_uniqueness_of(:encrypted_*) doesn't seem to work.

Could this be solved by a custom validator such as "validates :field, :encrypted_uniqueness => true"

Thoughts?

Looking at existing usages for validates it could also support an extra option in the uniqueness specifier:

  validates :name, uniqueness: {case_sensitive: true, encrypted: true}, presence: true

This does however assume that the field against which the uniqueness is being tested does not have the random_iv: true option set. The encrypted value will always be unique in that case even if the decrypted value is the same.

A pull request with such a change will be very useful, as I have no doubt others have the same need.
