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

Apabila menghadapi masalah seperti ini, saya biasanya mencari projek secara global lname
Mesti ada kod tambahan yang hilang di suatu tempat l
Cuma cari dan ubah suainya~
