Answer 1

I know, what you met. if you strong params is

def result_params
  params.require(:result).permit(:data)
end

Your parameters should has the format like this

Parameters: {"result"=>{"data"=>"string"}}

and your parameters is just

Parameters: {"data"=>"string"}

so you should remove the "result"
