Boolean validation failed

[hidogcat]

Hi there,
There is a defect about validation, for example:
WHEN
params: some_name do
xxx
requires :some_symbol, type: Grape::API::Boolean, allow_blank: false
xxx
end
THEN
send the request with some_symbol = false
GOT
a bad request with "error": "some_name[some_symbol] is empty"

This happened when allow_blank is false

Best regards,
Zhijia

Please try to write a spec for this?

I've noticed this too. I believe it's because the allow_blank validator is using the rails present? method which will treat false as not present and therefore fail the validation.

I forked the repo and added a failing test here https://github.com/mfunaro/grape/blob/master/spec/grape/validations/validators/allow_blank_spec.rb
