Question

我有三个模特

class Property < ActiveRecord::Base
  has_many :contact
  accepts_nested_attributes_for :contact
  has_many :business
  accepts_nested_attributes_for :business
end

class Business < ActiveRecord::Base
  belongs_to :property
  has_many :contact
end

class Contact < ActiveRecord::Base
  belongs_to :property
  belongs_to :business
end

我创建了一个使用嵌套联系人和嵌套业务创建Property的表单，如何让该业务与嵌套联系人建立？

这是我的表格

 <%= form_for(@property) do |f| %>
  <div class="field">
    <%= f.label :address %><br>
    <%= f.text_field :address %>
  </div>
 <% end %>
 <%= f.fields_for :contact do |contact_form| %>
  <div class="field">
    <%= f.label :contact_title, "Title" %><br>
    <%= contact_form.text_field :title %><br>

    <%= f.label :contact_name, "Name" %><br>
    <%= contact_form.text_field :name %><br>
  </div>
 <% end %>
 <%= f.fields_for :business do | business_form| %>
    <div class="indv-biz field">
      <%= f.label :business_name, "Name" %><br>
      <%= business_form.text_field :name %><br>
    </div>
     <div class="business-contact">
     <p>Business Contact</p>
  <%= f.fields_for :business_contact do | business_contact | %>
    <div class="field">
      <%= business_contact.label :contact_title, "Title" %><br>
      <%= business_contact.text_field :title %><br>
 <% end %>
 <% end %>

我可以保存，以便业务连接到该属性，并且联系人已连接到该属性，但我无法弄清楚如何将联系人连接到该业务

你应该像this一样尝试深度嵌套。您的要求是拥有许多业务的财产，而这些业务又有很多联系方式。在这种情况下，您实际应该做的是为业务设置属性的嵌套表单，并且该业务应该具有嵌套的联系人形式。下面的一个适合你。

<强>表格

nested_form_for @property do |f| 
  ...
  f.fields_for :bussiness do |bussiness_form|
    ...
    bussiness_form.fields_for :contact_form do |contact_form|
       ....
      end
    end
  end
end

<强>模型

class Property < ActiveRecord::Base
  has_many :contact

  has_many :business
  accepts_nested_attributes_for :business
end

class Business < ActiveRecord::Base
  belongs_to :property
  has_many :contacts
  accepts_nested_attributes_for :contacts
end

class Contact < ActiveRecord::Base
  belongs_to :property
  belongs_to :business
end

<强>控制器

def property_params
      params.require(:property).permit(:id,.., :bussiness_attributes => [:id,.., , :contacts_attributes => [:id, ..]])
  end
