ruby-on-rails - 在 rails 中收藏用户配置文件

Question

所以我创建了一个具有用户配置文件的网络应用程序，用户可以在其中根据兴趣等搜索其他用户。我如何添加用户可以收藏个人配置文件的功能？ IE。用户 A 找到用户 B 并喜欢他们看到的内容，然后可以单击“收藏此配置文件”按钮，也许它已加星标并存储？代码会是什么样子？只是一个想法，但我对所有想法持开放态度。

Answer 1

创建一个与 User 具有 has_and_belongs_to_many 关系的 Favorite 模型

创建收藏模型并建立关系后，您可以执行以下操作:

@user.favorites = [ user1, user2, user3 ]
@user.favorites << user4

将收藏夹分配给用户，或用类似的东西显示它们:

<%= @user.favorites.map(&:name).to_sentence %>

您将在此处找到有关如何执行此操作所需了解的所有信息:http://guides.rubyonrails.org/association_basics.html
