reusable params with shared helper - Boolean type problem

[chrisyoumans]

When defining a reusable parameter using a shared helper, if my parameter is of type Boolean, I receive a NameError. (block in module:ParamsHelper': uninitialized constant ParamsHelper::Boolean (NameError))

module ParamsHelper
  extend Grape::API::Helpers

  params :forensics do
    optional :forensics, type: Boolean, default: false, desc: "Turn forensics node on or off."
  end
end

All other types seem to work fine. It's as if it doesn't know where to look for the Boolean type. I even tried type: Grape::Validations::ParamsScope::Boolean and received: "block in module:ParamsHelper': uninitialized constant Grape::Validations::ParamsScope::Boolean (NameError)." I did the equivalent with String and while it threw a warning, it worked.

It's very possible I'm missing something, but considering the other types seem to work fine, I'm not sure what it could be.

OK, the problem goes away if I use type: Virtus::Attribute::Boolean. Seems a little strange considering that isn't necessary when the params are declared inside of the resource, but it works.

This behavior is because that 'Boolean' constant is defined under Grape::API, here. So it can be reached when you're inside an instance of Grape::API, but not from your module. I agree it's a little silly, though; it's always seemed weird to me that Ruby doesn't have a Boolean type when it has Integer, String, etc.

I am not sure we can do anything about this, closing.
