you might try to reload model and inspect it again:
您可能会尝试重新加载模型并再次检查它：
request.reload
puts request.last.inspect
though according to your code snippet the model must be persisted - save! would throw error otherwise.
虽然根据你的代码片段，模型必须保持 - 保存！否则会抛出错误。
P.S. I'd rather leave a comment on your question but don't have enough reputation.
