Symfony实体属性在树枝中未能识别

Question

我有一个形式，我想通过使用{{app.user.mail_2}}来设置输入的值，但是当我这样做时，我会收到错误：

均不是属性" mail_2"，也不是一种方法" mail_2(("，>" getMail_2(("/" ismail_2(("/" hasmail_2(("或" __call(("或" __call(("在" Baj BookingBundle Entity drivers"中。

我已经将其用于姓名，并且有效。

这是我的html.twig代码

      <div class="clear"></div>
                <div id="email-2" class="form_element email-facultatif">
                    <div>2ème e-mail (facultatif)</div>
                    <input type="email" class="email-mobile-width" 
    name="drivers[email_2]" placeholder="EMAIL" value="{{ app.user.mail_2 }}" 
    style="border-bottom-right-radius: 0px;border-top-right-radius: 0px;width: 
    224px;"/>
                    <div class="email-facultatif-block" id="email-2-img"><img
                                src="{{ asset('bundles/bajbooking/images/moin- 
    icon.png') }}" style="width: 41px;"></div>
                </div>

Answer 1

" mail_2"属性没有公共访问(这是正常(，而getMail_2((方法中不存在。

{{ app.user.getMail2() }}或 {{ app.user.mail2 }}应该起作用。

此外，建议不是使用下划线作为变量和方法名称。

Answer 2

我不认为这是抛出错误的行。该错误说实体"驱动程序"没有属性" mail_2"，而您正在调用" app.user"，该应用程序是完全认可的登录用户。

我认为您已调用driver.email_2的页面上的其他地方。
