Hello,
This is just a question, wanted to understand why are we checking values are present for request params over checking if key is present in request.
# File actionpack/lib/action_controller/metal/strong_parameters.rb, line 424 def require(key) return key.map { |k| require(k) } if key.is_a?(Array) value = self[key] if value.present? || value == false value else raise ParameterMissing.new(key) end end
so we can have params.require(:parameter).permit(:another_parameter)?
Thanks,
Sumit M
