有没有办法在ROR表单中创建数量不定的嵌套资源？

class ParentModel < ApplicationRecord
  has_many :child_models
  accepts_nested_attributes_for :child_models, allow_destroy: true
end

class ParentModelsController < ApplicationController
  def new
    @parent_model = ParentModel.new
    @parent_model.child_models.build
  end

  def create
    @parent_model = ParentModel.new(parent_model_params)
    if @parent_model.save
      # 保存成功的处理逻辑
    else
      # 保存失败的处理逻辑
    end
  end

  private

  def parent_model_params
    params.require(:parent_model).permit(:attribute1, :attribute2, child_models_attributes: [:id, :child_attribute1, :child_attribute2, :_destroy])
  end
end

<%= form_for @parent_model do |f| %>
  <%= f.text_field :attribute1 %>
  <%= f.text_field :attribute2 %>

  <%= f.fields_for :child_models do |child_form| %>
    <%= child_form.text_field :child_attribute1 %>
    <%= child_form.text_field :child_attribute2 %>
    <%= child_form.check_box :_destroy, class: 'remove-child' %>
  <% end %>

  <div class="actions">
    <%= f.button 'Add Child', class: 'add-child' %>
    <%= f.submit 'Submit' %>
  </div>
<% end %>

<script>
  $(document).ready(function() {
    $('.add-child').click(function(e) {
      e.preventDefault();
      var childFields = $('.fields').last().clone();
      childFields.find('input').val('');
      childFields.insertAfter($('.fields').last());
    });

    $('.remove-child').click(function() {
      $(this).closest('.fields').remove();
    });
  });
</script>
