favouriting users profiles in rails

Question

所以我創建了一個具有用戶配置文件的Web應用程序，用戶可以根據興趣等搜索其他用戶。我如何添加一個功能，以便用戶可以收藏個人配置文件？即用戶A找到用戶B並喜歡他們看到的內容，並且可以單擊「收藏該個人資料」按鈕，也許它已加星標並存儲？代碼是什麼樣子的？只是一個想法，但我願意接受所有想法。

創建與用戶一旦創建了最喜愛的模型

一個has_and_belongs_to_many關係最喜愛的模型，並建立了關係，你可以做這樣的事情：

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

給用戶指定收藏夾，或者用類似的方式顯示它們：

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