Don't custom paranoid gem.You can write: |
| class Client < ActiveRecord::Base | ||
| acts_as_paranoid | ||
|
|
||
| validates :name, uniqueness: { paranoia: :with_deleted } |

Doesn't work for me

Doesn't work for me either in rails v4.2.10 using MySQL. Traced it a bit and I found that rails wasn't actually removing the scope via the unscope method because of the way the relation query is set up. By the time it hits here, the relation is wrapped and chained with an AND query. It doesn't get through this case statement to actually remove the column from the scope because the relation rel is a Arel::Nodes::And at that point.
I just ended up making my own validator which manually checked for uniqueness against the unscoped records to move forward.
Paranoia doesn't support unique validation including deleted records: rubysherpas/paranoia#333 We use a custom validator, ScopedUniquenessValidator to avoid the issue

For with_default_scope add a
paranoia: :with_deletedoption when you want to ensure uniqueness on all records.For without_default_scope add a
paranoia: :without_deletedoption when you want to ensure uniqueness on only non-deleted records.
