Question

我试图用2级嵌套资源处理表单。我的资源是供应商。我已经在新的广告编辑表单中添加（构建）新的信条（地址）。我也以新的形式添加（建立）了相似的骗子（联系人），但我在编辑形式中添加了欺骗性（联系人）的问题。在编辑表单中，我希望在每次联系后添加提交按钮[添加联系人]，当用户点击此按钮时，转到更新方法并在正确的地址中构建新的联系人实例 - 我需要发送[添加联系人]提交带有地址ID的参数。我不知道该怎么做。我尝试隐藏字段但它从循环中发送最后隐藏的字段值。是否有机会使用提交按钮发送不同的参数？

我有2级嵌套资源。供应商有必要 - ＆gt;地址地址已经过时了 - ＆gt;接触

型号：供应商：

has_many :supplier_addresses
   has_many :addresses, :through => :supplier_addresses
   accepts_nested_attributes_for :addresses, 
                            :allow_destroy => true,
                            :reject_if     => :all_blank

地址：

has_many :address_contacts
   has_many :contacts, :through => :address_contacts
   accepts_nested_attributes_for :contacts, 
                            :allow_destroy => true,
                            :reject_if     => :all_blank

联络：

 has_many :address_contacts
   has_many :addresses, :through => :address_contacts

Suppliers_Controller：

   before_action :set_supplier, only: [:show, :edit, :update, :destroy]

   def index

        @suppliers = Supplier.paginate(page: params[:page], :per_page => 15).by_letter(params[:search])

  end

   private
    # Use callbacks to share common setup or constraints between actions.

      @supplier = Supplier.find(params[:id])
    end

    #for new add

    end

    #for new add
    def add_contact?
      params[:commit] == "Add contact"

    # Never trust parameters from the scary internet, only allow the white list through.
    def supplier_params
      params.require(:supplier).permit(:name, :notes, :min_order, :pay_terms, 
                                       addresses_attributes: [:id, :name, :street1, :street2, :county, :city, :country, :post_code, :_destroy,

    end

end

形式：

<%= form_for(@supplier) do |f| %>

      <%= f.label :name %>
      <%= f.text_field :name %>

  <%= f.fields_for :addresses do |address| %>

    <%= address.label :street %>
    <%= address.text_field :street %>

    <%= address.fields_for :contacts do |contact| %>

    <%= contact.label :job_title %>
    <%= contact.text_field :job_title %>

    <%end%>

    <%=hidden_field_tag params[:add_id], address.index%>
    <div class="row">
      <div class="actions text-center">
        <%= f.submit  "Add contact",:class => 'btn btn-sm btn-warning custom2' %>
      </div>
    </div>

  <%end%>

  <div class="row">
