ruby-on-rails - Rails 4 MongoID 嵌入式文档

Question

我有以下模型

class Professional
  include Mongoid::Document
  field :first_name, type: String
  field :last_name, type: String
  field :company_name, type: String
  field :address, type: String


  validates :first_name, length: { minimum: 5, :message => "What" }, format: { with: /\A[a-zA-Z]+\z/, message: "only allows letters" }
end

我想包含一个嵌入式文档，我可以在其中存储多个办公地址。我正在寻找以下数据库结构

{
  "first_name": "Harsha",
  "last_name": "MV",
  "company_name": "Mink7",
  "offices": [
    {
      "name": "Head Office",
      "address": "some address here"
    },
    {
      "name": "Off Site Office",
      "address": "some large address here"
    }
  ]
}

Answer 1

您必须定义该模型正在嵌入 office 对象，反之亦然，此处解释:http://mongoid.org/en/mongoid/docs/relations.html .我猜您需要一个 1-N 关系，以便 Professional 可以嵌入多个办公室？在那种情况下，类似这样的事情应该可行。

专业模特

class Professional
  include Mongoid::Document
  field :first_name, type: String
  field :last_name, type: String
  field :company_name, type: String
  field :address, type: String


  validates :first_name, length: { minimum: 5, :message => "What" }, format: { with: /\A[a-zA-Z]+\z/, message: "only allows letters" }

  embeds_many :offices, class_name: "Office"
end

办公模型

class Office
  include Mongoid::Document
  field :name, type: String
  field :address, type: String

  embedded_in :professional, :inverse_of => :offices
end

请记住，如果您要为这些对象使用一种形式，则必须使用嵌套形式，例如(或只是谷歌搜索):

<%= form_for @professional, :url => { :action => "create" } do |o| %>
    <%= o.text_field :first_name %>
    <%= o.text_field :last_name %>

    <%= o.fields_for :office do |builder| %>
        <%= builder.text_field :name %>
        <%= builder.text_field :address %>
    <% end %>
<% end %>

请注意，没有任何内容经过测试。
