Usage

Installing hanami-validations enables support for params validation in hanami-controller’s Hanami::Action classes.

class Signup < Hanami::Action
  params do
    required(:first_name)
    required(:last_name)
    required(:email)
  end

  def handle(req, *)
    puts req.params.class            # => Signup::Params
    puts req.params.class.superclass # => Hanami::Action::Params

    puts req.params[:first_name]     # => "Luca"
    puts req.params[:admin]          # => nil
  end
end

See hanami-controller for more detail on params validation.
