validates_uniqueness_of scoped to multiple columns
ruby, ruby-on-rails
Solution
Yes, it's valid and your syntax is exactly the way to achieve it. See the validations documentation page for more details.
Problem
When using Validates_uniqueness_of with the :scope option, is it valid to pass an array of columns like this: ``` validates_uniqueness_of :x, :scope => [:y, :z] ``` As I want :x to be unique in the context of both :y and :z If not then how could you achieve this? 2 validations one for each scope? Thanks
