我有以下表格:用户、朋友、兴趣和假期。 这项评估的目的是重新重视用户的利益和他们庆祝的假期(包括朋友出生日、周年纪念日)以及朋友的利益,以便以相关内容发出催复通知。 任何途径:

A user will have interests
A user will have friends
Friends will also have Interests
A user will have holidays they celebrate (a list of about 10)
-If mothers day, fathers day, or valentines day is selected (in the holidays) I will need to store the persons name and their interests as well

因此,不禁要问如何确定这些内容。 trick计是利益和假期。

如果利益是多变的,那么用户和朋友都可以接触吗? 或者有许多:通过?

假期是什么? 他们如何记录姓名和个人利益?

感谢! 真正为这一努力而奋斗,可能克服重叠。

最佳回答

现在我想我理解你想要做些什么,这就是我如何模仿:

<编码> 用户:

has_many :friends
has_many :person_interests, :as => :person
has_many :interests, :through => :person_interests
has_many :user_holidays
has_many :holidays, :through => :user_holidays

www.un.org/apps/

belongs_to :user
has_many :person_interests, :as => :person
has_many :interests, :through => :person_interests

www.un.org/spanish/ga/president

belongs_to :interest
belongs_to :person, :polymorphic => true

www.un.org/Depts/DGACM/index_spanish.htm

has_many :person_interests
has_many :people, :through => :person_interests # may need an `inverse_of` here

<编码> 用户Holiday:

belongs_to :user
belongs_to :holiday

www.un.org/Depts/DGACM/index_spanish.htm

has_many :user_holidays
has_many :users, :through => :user_holidays

有了这些安排,你就能够回答你需要回答的问题。
