通讯录的Rails模型（公司，人员，地址） [英] rails models for address books (company, person, address)
问题描述
我想创建一组类似于地址簿的模型来表示公司，人员，位置等。这看起来非常典型，我想知道是否有人已经在Ruby 3上做到了这一点。问题似乎不存在（仅）是由于我的懒惰，也是因为最佳实践方法通常很发达，陷阱少等。目前，我正在考虑以下模型/领域：
I want to create address-book-like set of models to represent company, person, location, etc. This looks like very typical address book, I wonder if somebody did it already with ruby on rails 3. The question appeared not (only) because of my laziness, but also because "best practice" approach is usually well-developed, have fewer pitfalls, etc. Currently I think about following models/fields:
公司：
- name
- has_many：persons
- has_many：locations
-
has_many：urls，：through =>：urlcatalog
- name
- has_many :persons
- has_many :locations
has_many :urls, :through => :urlcatalog
拥有URL目录的原因是可以为URL分配注释
the reason to have URL catalog is a possibility to assign notes to URL
人员：
- 名称可能会被拆分为第一中最后一位
- 电话
- has_one：location
-
has_many：emails：through =>：emailcatalog
- name maybe split to first-middle-last
- phone
- has_one :location
has_many :emails :through => :emailcatalog
拥有电子邮件目录的原因相同上面的代码：可以给
分配私人，办公室标签。
the reason to have email catalog is the same as above: one can assign "private", "office" labels to it. many phones can be organized this way as well.
位置
- 地址可选
- has_one：city
-
has_one：国家
- address optional
- has_one :city
has_one :country
应该存在城市或国家
城市
- 名称
- has_one：国家
国家/地区
- 名称

推荐答案
您应该查找多态关联。这意味着您的位置将得到更好的组织，并且更容易获得父母身份等等。
You should look up polymorphic associations. This means your location will be better organized and it will be easier to get parent etc...
