Ruby on rails 如何让两个循环在彼此之间显示信息

我有两个输入字段，由两个不同的哈希生成

table_head = {"key1"=>"thead1", "key2"=>"thead2", "key3"=>"thead3", "key4"=>"thead4"}

table_content = {"1"=>"column1", "2"=>"column2", "3"=>"column3", "4"=>"column4"}

 <%= form_for([@category, @page], url: update_pages_path) do |f| %>

    <% @page.table_head.each_with_index do |(key, value), i| %>
      <%= text_field_tag ('header[' + i.to_s + ']'), value %> 
    <% end%>


    <% @page.table_content.each_with_index do |(key, value), i| %>
      <%= select_tag 'content[' + i.to_s + ']', options_for_select(@category_keys, value), { :multiple => true, :size => 3}  %>
    <% end%>


 <% end %>

但是在内容字段中不能输入select

值

的默认

选项

如何将字段排序为head、content、head、content等。。插入头、头、头、头、内容、内容等。
表头={“键1”=>“thead1”、“键2”=>“thead2”、“键3”=>“thead3”、“键4”=>“thead4”}
table_head = {"key1"=>"thead1", "key2"=>"thead2", "key3"=>"thead3", "key4"=>"thead4"}

table_content = {"1"=>"column1", "2"=>"column2", "3"=>"column3", "4"=>"column4"}

<%= form_for([@category, @page], url: update_pages_path) do |f| %>
  <% @page.table_head.zip(@page.table_content).each do |head, content| %>
    <% head_key, head_value = head %>
    <% content_key, content_value = content %>
    <%= text_field_tag ('header[' + head_key + ']'), head_value %> 
    <%= select_tag 'content[' + content_key + ']', options_for_select(@category_keys, content_value), { :multiple => true, :size => 3}  %>
  <%end%>
<% end %>

表内容={“1”=>“column1”，“2”=>“column2”，“3”=>“column3”，“4”=>“column4”}
正确，：大小=>3}%>
我将如何将其应用于表单？像这样@user3234020将更加具体，并询问我如何使用
.zip
单独访问每个哈希值，而不是作为一个完整的哈希值。我试试你最新的答案。
table_head = {"key1"=>"thead1", "key2"=>"thead2", "key3"=>"thead3", "key4"=>"thead4"}

table_content = {"1"=>"column1", "2"=>"column2", "3"=>"column3", "4"=>"column4"}

<%= form_for([@category, @page], url: update_pages_path) do |f| %>
  <% @page.table_head.zip(@page.table_content).each do |head, content| %>
    <% head_key, head_value = head %>
    <% content_key, content_value = content %>
    <%= text_field_tag ('header[' + head_key + ']'), head_value %> 
    <%= select_tag 'content[' + content_key + ']', options_for_select(@category_keys, content_value), { :multiple => true, :size => 3}  %>
  <%end%>
<% end %>
