I had a situation where I needed to pass an array of integers in the query string.
I tried using
array_of: Integerbut this didn't work, because the values was passed in as an array of strings:["1", "2"]instead of[1, 2].This PR fixes that by allowing ArrayValidator to use other validators to validate the elements of the parameter array. So I was able to use
array_of: :number. It should work for other validators too because it looks them up withBaseValidator.find.I also added a spec.
