复选框状态控制-最佳选项？（javascript/jquery、数据库或其他）

我正试图找到实施解决方案的最佳方法，我想听听你对此的看法

我有一个表单rails-simpleform和几个字段。其中一些字段有一个关联的复选框。复选框的用法很简单：如果用户希望将字段留空，则数据可能丢失，他需要选中复选框，这是为了确保他将字段留空

现在我用javascript和jquery验证控制复选框。对于我在模型上使用的字段，进行以下验证

validates :field, acceptance: true, :unless => :field?

这是有效的，除非用户忘记输入一些数据，rails抛出一些错误，例如：字段必须被接受，然后页面刷新，复选框状态丢失

为了在编辑或更新操作中控制这一点，我在文档加载时运行了一个脚本，该脚本检查字段的内容是否为空，如果为空，则表示应选中该复选框

除此之外，当出现错误并刷新页面时，新建或创建操作也不起作用

所以我在寻找更好的解决方案。。。我应该使用jquery.cookie之类的东西并将复选框状态存储在cookie上吗？我是否应该将所有复选框添加到数据库并以这种方式控制状态？我不喜欢用巨大的表来控制数据库中的一切。。。我应该将状态作为参数传递到表单上吗

您对实现这一目标的最佳解决方案有何想法

--更新--

以下是控制器代码：

respond_to do |format|
  if @sample.save
    format.html { redirect_to @sample, notice: 'Sample was successfully created.' }
    format.json { render json: @sample, status: :created, location: @sample }
  else
    format.html { render action: "new" }
    format.json { render json: @sample.errors, status: :unprocessable_entity }
  end
end

在这方面：

<% if @sample.errors.any? %>
  <div id="error_explanation" class="field_with_errors">
    <h3>Não foi possível gravar o registo. Erro(s) encontrado(s): <%= pluralize(@sample.errors.count, "erro") %></h3>
    <ul>
    <% @sample.errors.full_messages.each do |msg| %>
      <li><%= msg %></li>
    <% end %>
    </ul>
  </div>
<% end %>

听起来您在控制器中所做的事情与Rails颗粒相反。如果您在控制器的else中使用@resource来响应_，那么您应该会看到一个页面重新加载，其中包含内联呈现的错误，并记住除密码以外的信息。它看起来确实正确。@sample的另一个非密码信息还在吗？还有，你能把你的表格放上去吗？最后，能否尝试删除验证中的除非：：字段部分？是的，其余字段仍然存在。只有复选框失去了它们的状态。我也尝试了不使用除非：：字段，但行为是一样的

<%= simple_form_for @sample, :html => { :class => 'form-horizontal' } do |f| %>
<!-- Error messages while saving-->
<% if @sample.errors.any? %>
  <div id="error_explanation" class="field_with_errors">
    <h3>Não foi possível gravar o registo. Erro(s) encontrado(s): <%= pluralize(@sample.errors.count, "erro") %></h3>
    <ul>
    <% @sample.errors.full_messages.each do |msg| %>
      <li><%= msg %></li>
    <% end %>
    </ul>
  </div>
<% end %>
<br>
<!-- end of error messages -->
