Rails的AJAX：我的部分需求FormBuilder实例 [英] Rails AJAX: My partial needs a FormBuilder instance

问题描述

所以，我有我的Rails应用程序的一种形式，它使用的自定义FormBuilder给我一些自定义字段标签

So I've got a form in my Rails app which uses a custom FormBuilder to give me some custom field tags

<% form_for :staff_member, @staff_member, :builder => MyFormBuilder do |f| %>
[...]
    <%= render :partial => "staff_members/forms/personal_details", :locals => {:f => f, :skill_groups => @skill_groups, :staff_member => @staff_member} %>	
[...]
<% end %>

现在，这部分是它通过一个AJAX回调得到替换形式的区域。我最终从控制器操作的响应于AJAX请求是：

Now, this partial is in an area of the form which gets replaces by an AJAX callback. What I end up doing from the controller in response to the AJAX request is:

render :partial => "staff_members/forms/personal_details", :locals => {:skill_groups => @skill_groups, :staff_member => @staff_member}

但是，如果我这样做，那么表单休息，为FormBuilder对象我以前在的form_for不再可用。有什么办法，我用我的自定义FormBuilder对象中部分使用了一个AJAX回调？

However, if I do that then the form breaks, as the FormBuilder object I used in the form_for is no longer available. Is there any way for me to use my custom FormBuilder object inside a partial used for an AJAX callback?

推荐答案

使用 fields_for 里面的部分。它执行类似的任务，但没有包装的形式标记。请参阅 API文档。

Use fields_for inside your partial. It performs a similar task but without wrapping the form tags. See the API docs.
