如何在控制器中向rails params添加属性并传递给不同的控制器

Question

upload_controller
 def create
  file = @upload.file
  content = File.read file
  params['content'] = content
 end
end

此处params['content']具有适当的文件内容。

book_controller
 def create
  @book.description = params['content']
  @book.save
 end
end

但params['content']中的book_controller.rb会返回nil

如何将内容从上传控制器传递到图书管理员？
