Misbehaviour in "uniqueness" validation

[loureirorg]

ActiveRecord's built-in uniqueness validation does not account for records deleted by paranoid2.

[loureirorg]

a workaround is to use:

uniqueness: { conditions: -> { where(deleted_at: nil) } }

instead of:

uniqueness: true

[yury]

Uniqueness validator by default uses unscoped scope

Not sure if we need to change this. You won't be able to restore deleted record (it would be invalid)

[loureirorg]

actasparanoid has solved this by adding a custom uniqueness validator.

its use:

validates_uniqueness_of_without_deleted :name

istead of:

validates_uniqueness_of :name

[yury]

@loureirorg you can use following scope to make code a little bit cleaner for now.

uniqueness: { conditions: -> { paranoid_scope } }

I will think more about this validator.

Thank you for your report
