Symfony2 ajax表单验证在树枝中渲染错误

i have a form in Symfony2 which i validate with ajax. This is all working, and i get back a json with "global" (for global errors) and "fields" (errors for each field in here) in my success statement of the ajax call:

我在Symfony2中有一个表单，我用ajax验证。这一切都正常，我在ajax调用的成功声明中找回了一个带有“global”（全局错误）和“fields”（这里的每个字段的错误）的json：

{"global":[],"fields":{"fos_user_registration_form_username":"Please enter a 
username","fos_user_registration_form_email":"Please enter an 
email","fos_user_registration_form_plainPassword_first":"Please enter a password"}}

My question is: What is the best way to present these errors from "fields" in the view for each field? I rendered the view elements as the following when i validated the form without ajax:

我的问题是：在每个字段的视图中，从“字段”中显示这些错误的最佳方法是什么？当我验证没有ajax的表单时，我将视图元素渲染为：

 <div class="form-group">
   {{ form_label(form.xyz) }}
   {{ form_widget(form.xyz) }}
   {{ form_errors(form.xyz) }}
 </div>

How can i inject now the errors from the "field" list of my json object into the appropriate

我怎样才能将我的json对象的“field”列表中的错误注入到相应的中

{{ form_errors(form.xyz) }}

？

I would love to hear your ideas and best practices.

我很想听听你的想法和最佳实践。

You add them via Javascript/jQuery.

你通过Javascript / jQuery添加它们。

I've a similar situation and this is my code:

我有类似的情况，这是我的代码：

The Js code that post form data and show errors messages in case of errors.

发布表单数据并在出现错误时显示错误消息的Js代码。

$.ajax({

    url : $(this).attr('action') + ".json",
    method : 'POST',
    data : $(this).serialize(),

}).done(function(data) {

        // Code in case of success

}).fail(function(jqXHR) {

   $.each(jqXHR.responseJSON.errors.children, function(k, v) {

       errorsText = "";

       if ((v.errors) && (v.errors.length > 0)) {
           $.each(v.errors, function(n, errorText) {
               errorsText += errorText;
           });
           $('#form_'+k).tooltip('destroy');
           $('#form_'+k).tooltip({'title': errorsText});    
           $('#form_'+k).closest('div[class="form-group"]').addClass('has-error');
        } else {
           $('#form_'+k).closest('div[class="form-group has-error"]').removeClass('has-error');
           $('#form_'+k).tooltip('destroy');
      }

   });
}

Here is my Json in case of error. Is the standard one you get if you use FOSRestBundle

如果出现错误，这是我的Json。如果您使用FOSRestBundle，则是标准配置

{
   "code":400,
   "message":"Validation Failed",
   "errors":{
      "children":{
         "name":{
            "errors":[
               "This value should not be blank."
            ]
         }
         "email":{
            "errors":[
               "This value should not be blank."
            ]
         }
         "privacy":{
            "errors":[
               "This value should not be blank."
            ]
         }
      }
   }
}

The HTML for my form is

我的表单的HTML是

<form id="sfForm" action="/landingbuilder/landing/test_template" method="POST">

    <div class="form-group">
        <label class="control-label required" for="form_name">Name</label>
        <input type="text" id="form_name" name="form[name]" required="required" class="form-control" />
    </div>

    [..]

</form>
