ruby - rails 开发 保存对象报错？

Question

目的：实现通过前段网页提交并保存一个一个company对象，这个对象只有一个字段，那就是name.

但是提交时保存却说：找不到lname方法！controller保存时并没有设计lname方法，不知道为什么会报这个错误。

2天了，没弄明白。

下面是报错：

NoMethodError in CompaniesController#create
undefined method `lname' for #<Company id: nil, name: "c1", created_at: nil, updated_at: nil>

Extracted source (around line #23):

21 def create
22 @company = Company.new(params[:company].permit(:name))
23 @company.save
24 redirect_to @company
25 end

Rails.root:

이런 문제가 발생하면 주로 프로젝트를 글로벌하게 검색합니다 lname 어딘가에 추가 코드가 누락된 게 있을 텐데요 l 찾아서 수정하면 됩니다~

도움이 되길 바랍니다~ :)
