symfony - 如何在 Symfony2 中使用具有 OneToMany 和 ManyToOne 关系的集合？

Question

我有一个包含联系人（联系人实体）、联系人的亲属（ContactRelative实体）和各种场合（AnniBirth实体）的数据库。我首先要做的是将联系人及其详细信息保存在联系人实体中。其次，我输入联系人的所有亲属（配偶、孩子等），我希望能够输入最多 4 次（生日、周年纪念日等）。我一直在研究 Symfony2 和学说的关系/关联，以寻求实现这一点的方法，我决定使用“集合”。

除了很多 AnniBirth 到 ContactRelatives 之外，一切对我来说都很清楚，我必须在其中显示一组嵌入的 AnniBirth 表单并将它们保存回数据库。

到目前为止，关系是：

1联系人可以有很多亲戚
1 个联系人可以有很多AnniBirths
1亲戚可以有很多AnniBirths

要求：

我将能够查看所有联系人的 annibirths、亲戚和他们的 AnniBirths。

问题：

联系人成功地将所有数据保存在 MySQL 数据库中。ContactRelative 和 AnniBirth 相同，但是在保存最后两个（ContactRelative 和 AnniBirth）的数据时，contact_id和 contactrelative_id不会更新或保存在表中。我知道我在收集和持久化数据方面犯了一个错误。我试图通过使用显示contact_id， \Doctrine\Common\Util\Debug::dump($contactRelative->getAnniBirths()->contact); exit();但我得到的只是NULL。
我希望能够显示 AnniBirth 表单 4 次，但我不知道如何实现。经过几天的搜索，我发现的唯一一件事是，如果我想显示一个没有 javascript 的嵌入式表单，我必须像这样直接使用“原型”：{{ form_widget(form.annibirths.vars.prototype)}}但只显示一个表单实例。

部分问题是这样的：

    public function addAnnibirth(\********\***Bundle\Entity\AnniBirth $annibirths)
    {
        $this->annibirths[] = $annibirths;

        return $this;
    }

你会注意到，虽然这指向了联系/相对于 annibirth，但 annibirth 并没有指向后面。这也许就是为什么另一位发帖人可能会建议做一个循环。但它是一个强大而简单的解决方案：

    public function addAnnibirth(\********\***Bundle\Entity\AnniBirth $annibirth)
    {
        $this->annibirths[] = $annibirth;
        $annibirth->setContact($this);  // or setRelative for the Relative entity.
        return $this;
    }

这可能会清除您持续存在的问题。太多的代码无法确定。但绝对需要以上改动。如果您仔细查看大多数示例，您会看到相同类型的行。容易被忽视。

一旦一切设置正确，就无需在持久化之前循环。

$contactRelative->annibirth = $ab1;这不应该是可能的，因为您在 ContactRelative 中将 annibirth 设置为受保护的。那应该会引发错误（如果您之前打开了错误）。你应该做的是$contactRelative->setAnnibirth($ab1);. 但那是为了附加 php 对象，数据库中的附加实际上是在 Annibirth 表中，该表包含一个contactRelative_id，因此您必须更新此对象：$ab1->setContactRelative($contactRelative);

找到了解决方案：

在控制器中添加：

foreach ( $contactRelative->getAnnibirths() as $anni ) 
                    { 
                        $anni-> setContactRelative($contactRelative); 
                        $anni-> setContact($contactRelative->getContact());
                    }

在树枝模板中：

{% for occasion in form.annibirths %}
     <div>
            {{ form_row(occasion.type) }}
            {{ form_row(occasion.repeating) }}
            {{ form_row(occasion.celebrationDate) }}
    </div>
{% endfor %}
