Rails 动态选择 - 验证未显示字段错误

在我的表单中，我有两个选择 - 州和城市。城市下拉列表取决于用户在州下拉列表中选择的内容。在我看来，我有以下内容：

<%= f.input :state_id, :collection => @states, :prompt => "Pick Your State" %>
<%= render :partial => 'cities', :locals => { :cities => @cities, :user => form } %>

城市部分如下所示：

<%= simple_fields_for :user do |fields| %>
  <% if cities.blank? %>
    <%= fields.input :city_id, :collection => cities, :prompt => "Pick Your State" %>
  <% else %>
    <%= fields.input :city_id, :collection => cities, :prompt => "Pick Your City" %>
  <% end %>
<% end %>

在我的模型中： validates_presence_of :state_id, :city_id

下拉菜单功能符合预期 - 如果重要的话，我正在使用 simple_form 和 jquery 。验证“起作用”是因为如果我不进行选择，记录将不会保存，而且实际上，我收到了解释问题的错误消息。然而，没有发生的是城市周围的 field_with_errors 包装器。我怀疑这与我使用部分有关，但我不确定。我需要创建某种自定义验证吗？

编辑：

我还注意到我的密码确认字段也没有获得 field_with_errors div （同样，尽管验证本身仍在强制执行）

原文

In my form, I have two selects - state and city. The city drop-down depends upon what the user selects in the state drop-down. In my view, I have the following:

<%= f.input :state_id, :collection => @states, :prompt => "Pick Your State" %>
<%= render :partial => 'cities', :locals => { :cities => @cities, :user => form } %>

The city partial looks like this:

<%= simple_fields_for :user do |fields| %>
  <% if cities.blank? %>
    <%= fields.input :city_id, :collection => cities, :prompt => "Pick Your State" %>
  <% else %>
    <%= fields.input :city_id, :collection => cities, :prompt => "Pick Your City" %>
  <% end %>
<% end %>

In my model:
validates_presence_of :state_id, :city_id

The drop-downs function as expected - I'm using simple_form and jquery if that matters. The validations "work" in that if I don't make a selection, the record won't save, and indeed, I get the error messages explaining the problem. What is not happening, however, is the field_with_errors wrapper around the city. I suspect it has to do with the fact that I am using the partial, but I'm not sure. Do I need to create a custom validation of some kind?

edit:

I also notice that my password confirmation field is not getting the field_with_errors div as well (again, though the validation itself is still being enforced)
