RuntimeError 即将到来 Rails 3

Question

当我使用 Rails 3.

提交表单时出现以下错误

错误：

HcsysController#create 中的运行时错误

Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
Rails.root: C:/Site/swargadwar_admin

Application Trace | Framework Trace | Full Trace
app/controllers/hcsys_controller.rb:12:in `create'

请帮帮我。

Answer 1

将 @hcsy.sdp_id=@sdp.id 更改为 @hcsy.sdp_id=@sdf.id ... 只是 @sdf.id
