无效消息未关联到字段

当两个密码字段不匹配时，我需要显示一个错误。我试图通过在repeated password字段中设置invalid_message来实现这一点，但当我试图将错误调用为{{form_errors(form.password)}}时，错误不会出现。但是，如果我使用{{form_errors(form)}}，则会出现密码不匹配错误。我需要使错误字段具体化，并将非常重视您在以下方面的输入：）

我尝试了许多在线搜索，但都无济于事。以下是我的实现，

• twig

            {{ form_start(form, {'attr': {'class': 'form-horizontal', 'role': 'form', 'novalidate': 'novalidate'}}) }}
              <!--just placed the error here for debug purposes-->
              {{ form_errors(form) }}  
              <div class="form-group {% if form.email.vars.errors|length > 0 %}has-error{% endif %} {% if form.email.vars.required == 'true' %}required{% endif %}">
               {{ form_label(form.email) }} 
                <div class="col-sm-8">
                  {{ form_widget(form.email) }}
                  <span class="help-block">{{ form_errors(form.email) }}</span>
                </div>
              </div>
              <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
