在添加第二个嵌套表单新字段时，第一个嵌套表单字段会在编辑中消失

Question

我有三个表

1） 客户2） 家庭3） 雇员

虽然以新形式添加新字段，但一切都很完美

但是在编辑形式中，如果我首先为家庭添加嵌套属性然后我为员工添加嵌套属性，然后为家庭添加的字段消失，为员工添加字段

        class Client < ActiveRecord::Base
         self.primary_key = "id"
         has_many :familys , dependent: :destroy, :foreign_key => 'client_id'
         accepts_nested_attributes_for :familys , allow_destroy: true
         has_many :employees , dependent: :destroy, :foreign_key => 'client_id'
         accepts_nested_attributes_for :employees , allow_destroy: true
        end

        class Family < ActiveRecord::Base
            belongs_to :client              
        end

        class Employee < ActiveRecord::Base
            belongs_to :client              
        end

       #-------_form.html.erb-----------------------------#
        <%= nested_form_for(@client) do |f| %>
        <div><%= f.submit 'addfamily',:name => "add_n_tenpo" %></div>
        <%= f.fields_for :familys  do |w| %>
         <tr>
            <td class="label_width">巡店店舗</td>
            <td><%= w.text_field :tenpo_code_1, class: 'form-control tenpoautofill' %></td>
            <td><%= w.text_field :tenpo_code_2, class: 'form-control tenpoautofill' %></td>
        </tr>
        <% end %>
        <div><%= f.submit 'addemployee',:name => "add_nw_tenpo" %></div>
        <%= f.fields_for :employees  do |nw| %>
        <tr>
              <td class="label_width">巡店店舗</td>
              <td><%= nw.text_field :nw_tenpo_code_1, class: 'form-control' %></td>
              <td><%= nw.text_field :nw_tenpo_code_2, class: 'form-control' %></td>
        </tr>
        <% end %>
        <% end %>

Answer 1

因为您需要显式传递familys的值，并以嵌套形式employees进行编辑操作，所以这不会影响新操作的形式，因为在新操作中@client为零，因此需要为编辑操作传递值。

试试这个

<%= nested_form_for(@client) do |f| %>
    <%= f.fields_for :familys_attributes, @client.familys  do |w| %>
     <tr>
        <td class="label_width">巡店店舗</td>
        <td><%= w.text_field :tenpo_code_1, class: 'form-control tenpoautofill' %></td>
        <td><%= w.text_field :tenpo_code_2, class: 'form-control tenpoautofill' %></td>
    </tr>
    <% end %>
    <%= f.fields_for :employees_attributes, @client.employees  do |nw| %>
    <tr>
          <td class="label_width">巡店店舗</td>
          <td><%= nw.text_field :nw_tenpo_code_1, class: 'form-control' %></td>
          <td><%= nw.text_field :nw_tenpo_code_2, class: 'form-control' %></td>
    </tr>
    <% end %>
    <% end %>
