我几周来就遇到了问题。 我在Google和Symfony文档上搜索了很多，但还没有找到解决方案。
问题是我总是收到此错误消息：
方法＆＃34;用户名＆＃34; for object＆＃34; Symfony \ Component \ Form \ FormView＆＃34;在第11行的admin / user / _form.html.twig中不存在
但不是每个FormType。
例如我的Field Entity没有问题。但我的User或CompanyType有这个问题。当我在树枝中dump(form)时一切正常，我可以看到像用户名这样的变量。它也显示在Profiler中。我比较了一个功能和一个功能。据我所知，它们完全相同。
同样奇怪的是，当我渲染整个表格时
form_row(form)它正在运作。
form_row(form.username)没有。
我正在使用Symfony 2.7.9
如果您现在需要别的东西，请告诉我。 抱歉，这是我第一次积极提问。
提前感谢您的帮助。
最诚挚的问候， 凯文

答案 0 :(得分：3)
choice_label选项必须是可调用函数或与Job实体上的property path相关的字符串。您的实体没有名为getUsername()的函数，并且没有$username的公共属性。
假设您的User实体具有getUsername()功能，您可以将以下功能添加到Job实体：
public function getUsername()
{
return ($this->user) ? $this->user->getUsername() : null;
}
答案 1 :(得分：1)
感谢大家的帮助，我刚刚找到了解决问题的方法。
问题是在Controller中我从同一DeleteForm模板渲染EditForm和_form.html.twig。
当我有一个删除模板时，使用form_widget(form)
和_form的行分开，一切都按预期工作。
希望你能从我的失败中吸取教训。
