ruby - 关于rails中devise登录用户名的调用问题

Question

我用devise进行了注册，这个时候登录的用户名如何传到首页的尾部script中？

这后面应该怎么取值？

Answer 1

before_action :verified_student

  private
  def verified_student
    authenticate_student!
  end

Here, authenticate_student will create a current_student, pointing to the current login student in students
