[英]One to Many relations and add/edit form in SonataAdmin and Symfony2
I have a simple Symfony2 application with two entities: Municipality and Poi. 我有一个包含两个实体的简单Symfony2应用程序:Municipality和Poi。 There is a relation "One-To-Many" between Municipality and Pois (ie: zero or more pois placed in one municipality), so the Entity files are like this:
市与Pois之间存在“一对多”关系(即:在一个市中放置零个或更多pois),因此实体文件如下所示:
Poc\\PocBundle\\Entity\\Municipality.php POC \\ PocBundle \\实体\\ Municipality.php
<?php
// Poc\PocBundle\Entity\Municipality.php
namespace Poc\PocBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Municipality
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="Poc\PocBundle\Entity\MunicipalityRepository")
*/
class Municipality
{
/**
* @ORM\OneToMany(targetEntity="Poi", mappedBy="municipality")
*/
protected $pois;
public function __construct()
{
$this->pois = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return Municipality
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Add pois
*
* @param \Poc\PocBundle\Entity\Poi $pois
* @return Municipality
*/
public function addPois(\Poc\PocBundle\Entity\Poi $pois)
{
$this->pois[] = $pois;
return $this;
}
/**
* Remove pois
*
* @param \Poc\PocBundle\Entity\Poi $pois
*/
public function removePois(\Poc\PocBundle\Entity\Poi $pois)
{
$this->pois->removeElement($pois);
}
/**
* Get pois
*
* @return \Doctrine\Common\Collections\Collection
*/
public function getPois()
{
return $this->pois;
}
public function __toString()
{
return $this->name;
}
}
Poc\\PocBundle\\Entity\\Poi.php POC \\ PocBundle \\实体\\ Poi.php
<?php
// Poc\PocBundle\Entity\Poi.php
namespace Poc\PocBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Poi
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="Poc\PocBundle\Entity\PoiRepository")
*/
class Poi
{
/**
* @ORM\ManyToOne(targetEntity="Municipality", inversedBy="pois")
* @ORM\JoinColumn(name="municipality_id", referencedColumnName="id")
*/
protected $municipality;
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return Poi
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set municipality
*
* @param \Poc\PocBundle\Entity\Municipality $municipality
* @return Poi
*/
public function setMunicipality(\Poc\PocBundle\Entity\Municipality $municipality = null)
{
$this->municipality = $municipality;
return $this;
}
/**
* Get municipality
*
* @return \Poc\PocBundle\Entity\Municipality
*/
public function getMunicipality()
{
return $this->municipality;
}
public function __toString()
{
return $this->name;
}
}
At this point, I want to manage the One-To-Many relation between the municipality and their pois from the Municipality add/edit form in Sonata Admin. 在这一点上,我想通过Sonata Admin中的“市政添加/编辑”表单来管理市政与市政局之间的一对多关系。
I have followed the instructions explained in http://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/form_field_definition.html#advanced-usage-one-to-many , so the MunicipalityAdmin class file is: 我已经按照http://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/form_field_definition.html#advanced-usage-one-to-many中的说明进行了操作,因此,MunicipalityAdmin类文件是:
Poc/PocBundle/Admin/MunicipalityAdmin.php POC / PocBundle /管理/ MunicipalityAdmin.php
<?php
namespace Poc\PocBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Show\ShowMapper;
class MunicipalityAdmin extends Admin
{
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('name')
->add('_action', 'actions', array(
'actions' => array(
'show' => array(),
'edit' => array(),
)
))
;
}
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('name')
->add('pois', 'sonata_type_collection', array(), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
}
The form I am trying to get is an add/edit form where I can define de name of the municipality and add/remove associated pois from the Poi entity, but what I actually get is a form where I can define the name of the municipality, and manage the Poi entity in a kind of sub-form. 我要获取的表单是一个添加/编辑表单,我可以在其中定义市政当局的名称,并从Poi实体中添加/删除相关的Pois,但实际上,我得到的是一种可以定义市政当局的名称的表单,并以一种子形式管理Poi实体。
This screenshoot describe the result --> http://i.imgur.com/nM1ywwh.png 此屏幕快照描述了结果-> http://i.imgur.com/nM1ywwh.png
I mean, in this way, I can add new Pois and relations with any municipality (ie: Los Angeles), but what I'm trying to get is a list of al pois that are related to this municipality and the posibility to: 我的意思是,通过这种方式,我可以添加新的Pois以及与任何市政当局(即洛杉矶)的关系,但是我要获取的是与此市政当局有关的al pois列表,并且可以:
I've seen the way to manage this in the reverse way, selecting the Municipality related to each Poi in the Poi add/edit form (Many-to-one), but I wonder if is there any way to manage this relations in the other entity. 我已经看到了相反的管理方式,可以在Poi添加/编辑表单(多对一)中选择与每个Poi相关的自治市,但是我想知道是否有任何方法可以在其他实体。
Can I do this in SonataAdmin? 我可以在SonataAdmin中这样做吗? Any clue?
有什么线索吗?
UPDATE: Solved the UI and adding pois, but not deleting 更新:解决了用户界面并添加了pois,但未删除
I've got the way to show widget that I am looking for, by definining the form in this way: 通过以这种方式定义表单,我已经可以显示想要的小部件了:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('name')
->add('pois', null, array(), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
What I did is to change 'sonata_type_collection' for null value. 我所做的是将“ sonata_type_collection”更改为空值。 Now I get a form like this screenshot -->
现在,我得到了这样的屏幕截图->
... that as just the behavior I want. ...这只是我想要的行为。
Initially, the additions in this widget (ie: add new pois to a municipality), didn't persist. 最初,此小部件中的添加项(即:向市政当局添加新的pois)并未持久。 Thanks to the comment of Radomir Wojtera, I realized that there was methods not implemented in my Municipality Entity class (setPois, addPoi and removePoi).
多亏了Radomir Wojtera的评论,我才意识到我的市级实体类(setPois,addPoi和removePoi)中没有实现一些方法。
I added this methods ... 我添加了这种方法...
public function setPois($pois)
{
if (count($pois) > 0) {
foreach ($pois as $i) {
$this->addPoi($i);
}
}
return $this;
}
public function addPoi(\Poc\PocBundle\Entity\Poi $poi)
{
$poi->setMunicipality($this);
$this->pois->add($poi);
}
public function removePoi(\Poc\PocBundle\Entity\Poi $poi)
{
$this->pois->removeElement($poi);
}
... and now I'm able to grab new Pois for a Municipality, but when I remove some Pois, they did't disassociate. ...现在我可以为市政当局获得新的Pois,但是当我删除一些Pois时,它们并没有分离。 so I can add relations, but not remove.
因此我可以添加关系,但不能删除关系。
Finally I can resolve the second issue (removing Poi from a Municipality didn't work) by setting orphanRemoval=true in Entity configuration 最后,我可以通过在实体配置中设置orphanRemoval = true来解决第二个问题(从市政当局删除Poi无效)
class Municipality
{
/**
* @ORM\OneToMany(targetEntity="Poi", mappedBy="municipality", cascade={"persist"}, orphanRemoval=true))
*/
protected $pois;
...
The first issue is solved as commented in the question update. 如问题更新中所述,第一个问题已解决。
