学说2：如何将除一个对象之外的所有值克隆到另一个对象上？

In $entity variable, there is an object of same type as $other_address, but with all field values filled in.

在$ entity变量中，有一个与$ other_address类型相同的对象，但填写了所有字段值。

I want to set all fields in $other_address object to have exact same values as $entity object.

我想将$ other_address对象中的所有字段设置为与$ entity对象具有完全相同的值。

Is this doable in less then N number of lines, where N is number of fields I need to set?

这是否可以少于N行，其中N是我需要设置的字段数？

I tried "clone" keyword, but it didnt work.

我尝试过“克隆”关键字，但它没有用。

Here's the code.

这是代码。

                $other_address = $em->getRepository('PennyHomeBundle:Address')
          ->findBy(array('user' => $this->get('security.context')->getToken()->getUser()->getId(), 'type' => $check_type));
                $other_address = $other_address[0];


                //I want to set all values in this object to have values from another object of same type
                $other_address->setName($entity->getName());
                $other_address->setAddress1($entity->getAddress1());
                $other_address->setAddress2($entity->getAddress2());
                $other_address->setSuburbTown($entity->getSuburbTown());
                $other_address->setCityState($entity->getCityState());
                $other_address->setPostZipCode($entity->getPostZipCode());
                $other_address->setPhone($entity->getPhone());
                $other_address->setType($check_type);

3 个解决方案

#1

I'm not sure why cloning won't work.

我不确定为什么克隆不起作用。

This seems to work for me, at least in a basic test case:

这似乎对我有用，至少在一个基本的测试用例中：

$A = $em->find('Some\Entity',1);

$B = clone $A;
$B->setId(null);

If you've got relationships to worry about, you might want to safely implement __clone so it does what you want it to do with related entities.

如果您有关系需要担心，您可能需要安全地实现__clone，以便它能够执行您希望它与相关实体做的事情。

Just Clone the entity, you don't even need to unset the id. Doctrine has tackled this for you

只需克隆实体，您甚至不需要取消设置ID。 Doctrine为你解决了这个问题

#3

$A = $em->find('Some\Entity',1);

$B = clone $A;
$em->persist($B);
$em->flush();

if you merge it will update the entity, best you use persist() it will duplicate the entire row and add auto incremented primary key

如果你合并它将更新实体，最好你使用persist（）它将复制整行并添加自动递增的主键
