Question

我有一个带有下拉框的搜索字段，我可以选择要搜索的列和内容，如下所示：

“+”按钮会添加另一个搜索字段，搜索会发送搜索表单。

我已经拥有获取此字段并将标记附加到它们的函数，使其成为元素数组。问题是，现在我有这个数组并且搜索不起作用，当我提交字段时，另一方没有返回，只有nil类。我试图在live_search中传递一个，并通过所有元素迭代它，但它也不起作用。我认为问题可能在控制器中，但我没有太多经验，所以我不知道该怎么做......

search_engine.html.erb

<div id="search-form">
  <%= button_tag "+", class: "add_field" %>
  <%= form_tag({controller: "people", action: "index"}, method: "get", class: "form_wrapper", remote: true) do %>
    <%= button_tag "search", class: "button_search" %>
  <% end %>
</div>

<script type="text/javascript">

  column =
  '<%  valid_column_names = Person.column_names.reject{|r| r == "created_at" || r == "updated_at" || r == "slug"} %>' +
  '<%= j (select_tag :object_columns, options_for_select(valid_column_names), class: "object_columns") %>' +
  '<%= text_field(:search, :record, autocomplete: :off, class: "search") %>';

  $('button.add_field').on('click',function(){
    $('.form_wrapper').after(column);
    format_fields();
  });

  function format_fields() {
    add_indexes();
    add_ids();
  }

  function add_indexes() {
    add_index_to('object_columns');
    add_index_to('search');
  }

  function add_ids() {
    add_ids_to('object_columns');
    add_ids_to('search');
  }

  function add_index_to(element) {
    var i=0;
    $('.'+element).each(function(){
      i++;
      var newName=element+'['+i+']';
      $(this).attr('name',newName);
    });
  }

  function add_ids_to(element) {
    var i=0;
    $('.'+element).each(function(){
      i++;
      var newID=element+i;
      $(this).attr('id',newID);
    });
  }

对于这个日志，我有两个活动搜索，一个用于ID，另一个用于Name。

如何在rails中创建和提交动态相等的搜索字段？
