Ruby on rails Rais应用程序用户特定索引将显示给所有用户

我制作了一个用于管理个人图书馆（书籍和漫画）的应用程序，它运行得很好，但它开始向所有用户（新的或现有的）显示给定用户介绍的所有书籍（似乎显示整个数据库）；但我已经设计并实施了权威认证，到目前为止，它一直在保护用户信息。。。。需要一些帮助来解决这个问题。 代码如下，但如果需要更多，请大声喊叫。 提前谢谢

Book_controller.rb

book.rb

classbookcsv重新分配@books实例变量时，上一个作用域将丢失。试试这样的东西：

@books=policy\u范围（Book）.order（：title）
@books=@books.search_by_full_name（params[：term]），如果params[：term]。是否存在？
回应待办事项|格式|
format.html{@books=@books.paginate（page:params[：page]））
format.csv{send_data@books.to_csv}
结束
您正在多次覆盖
@books
变量，而不是执行一些链接

@books=policy\u范围（Book）
@books=@books.search_by_full_name（params[：term]），如果params[：term]。是否存在？
@books=@books.order（：title）
回应。。。
结束
解决了它。。。我没有在每本书的视图/索引中应用当前用户。。。这样，每个用户都有自己的图书数据库，但当呈现索引时，它显示每个人的图书，不管是哪个用户创建的。。。大多数情况下都很简单：P
您在哪里筛选登录用户？这只是获取了我假定的所有内容
@books=Book.paginate（page:params[：page]）
class BooksController < ApplicationController
  before_action :authenticate_user!

  def index
    unless params[:term].present?
      @books = policy_scope(Book)

    @books = Book.order(:title)
    respond_to do |format|
      format.html
      format.csv { send_data @books.to_csv }
      format.xls # { send_data @products.to_csv(col_sep: "\t") }
