问题描述
代理实体
/ **
* @var \Doctrine\Common\Collections\ArrayCollection $ agentLists
*
* @ ORM\ManyToMany(targetEntity =AgentList ,inversedBy =agents)
* @ ORM\JoinTable(name =agent_agentlist,
* joinColumns = {@ ORM\JoinColumn(name =agent_id,referencedColumnName =id) }
* inverseJoinColumns = {@ ORM\JoinColumn(name =agentlist_id,referencedColumnName =id)}
*)
* /
protected $ agentLists;
/ **
*获取代理列表
*
* @return \Doctrine\Common\Collections\ArrayCollection
* /
public function getAgentLists()
{
return $ this-> agentLists;
}
/ **
*将代理列表添加到代理
*
* @param AgentList $ agentList
* /
public function addAgentList(AgentList $ agentList)
{
$ this-> agentLists-> add($ agentList);
$ agentList-> addAgent($ this);
}
/ **
*从代理中删除代理列表
*
* @param AgentList $ agentList
* /
public function removeAgentList(AgentList $ agentList)
{
$ this-> agentLists-> removeElement($ agentList);
$ agentList-> removeAgent($ this);
}
AgentList实体
/ **
* @var \Doctrine\Common\Collections\ArrayCollection $ agents
*
* @ ORM\ManyToMany targetEntity =Agent,mappedBy =agentLists)
* /
protected $ agents;
/ **
*获取代理
*
* @return \Doctrine\Common\Collections\ArrayCollection
* /
public function getAgents()
{
return $ this-> agents;
}
/ **
*添加代理
*
* @param代理$代理
* /
公共函数addAgent(Agent $ agent)
{
$ this-> agents [] = $ agent;
}
/ **
*删除代理
*
* @param代理$代理
* /
公共函数removeAgent(Agent $ agent)
{
$ this-> agents-> removeElement($ agent);
}
代理类型
- > add('agentLists',null,array('choices'=> $ this-> commercial-> getAgentLists(),'required'=> ));
在代理列表类型
- > add('agents',null,array(
'required'=> false,
'choices'=> $ commercial-> getAgents b $ b
只有在我使用AgentType的情况下才有效
如果我使用AgentListType不保存代理关系!
以同样的方式,如果我:
$ agent-> addAgentList($ agentList);
一切正常!
如果我:
$ agentList-> addAgent($ agent);
不保存任何东西...
解决方案
对于多对多我创建的嵌入字段,例如
- > add('agentsEmbed','collection',
array(
'type' => new AgentListType(),
'allow_add'=> true,
'allow_delete'=> true,
'prototype'=> true,
'property_path'=> false
)
)
控制器中的Afrer:
$ agents = $ form ['agentsEmbed'] - > getData();
if($ agents)
{
$ entity-> setAgentLists(new ArrayCollection());
foreach($ agents as $ agent)
{
$ entity-> addAgentList($ em-> getRepository('AgentList') - > find($ agent - >的getId()););
}
}
$ em-> persist($ entity);
$ em-> flush();
它适用于常见的多对多
I have a problem saving entities with forms. The relationship that gives me problems is many-to-many bidirectional.
Agent Entity
/**
* @var \Doctrine\Common\Collections\ArrayCollection $agentLists
*
* @ORM\ManyToMany(targetEntity="AgentList", inversedBy="agents")
* @ORM\JoinTable(name="agent_agentlist",
* joinColumns={@ORM\JoinColumn(name="agent_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM\JoinColumn(name="agentlist_id", referencedColumnName="id")}
* )
*/
protected $agentLists;
/**
* Get agent lists
*
* @return \Doctrine\Common\Collections\ArrayCollection
*/
public function getAgentLists()
{
return $this->agentLists;
}
/**
* Add agent list to agent
*
* @param AgentList $agentList
*/
public function addAgentList(AgentList $agentList)
{
$this->agentLists->add($agentList);
$agentList->addAgent($this);
}
/**
* Remove agent list from agent
*
* @param AgentList $agentList
*/
public function removeAgentList(AgentList $agentList)
{
$this->agentLists->removeElement($agentList);
$agentList->removeAgent($this);
}
AgentList Entity
/**
* @var \Doctrine\Common\Collections\ArrayCollection $agents
*
* @ORM\ManyToMany(targetEntity="Agent", mappedBy="agentLists")
*/
protected $agents;
/**
* Get agents
*
* @return \Doctrine\Common\Collections\ArrayCollection
*/
public function getAgents()
{
return $this->agents;
}
/**
* Add agent
*
* @param Agent $agent
*/
public function addAgent(Agent $agent)
{
$this->agents[] = $agent;
}
/**
* Remove agent
*
* @param Agent $agent
*/
public function removeAgent(Agent $agent)
{
$this->agents->removeElement($agent);
}
In Agent Type
->add('agentLists', null, array('choices' => $this->commercial->getAgentLists(), 'required' => false));
In AgentList Type
->add('agents', null, array(
'required' => false,
'choices' => $commercial->getAgents()
It only works if I use AgentType. If I use AgentListType don't save Agents Relations! In the same way, If I:
$agent->addAgentList($agentList);
All works fine! If I:
$agentList->addAgent($agent);
don't save nothing...
解决方案
For many-to-many i'm creating embed field, for example
->add('agentsEmbed', 'collection',
array(
'type' => new AgentListType(),
'allow_add' => true,
'allow_delete' => true,
'prototype' => true,
'property_path' => false
)
)
Afrer in controller:
$agents = $form['agentsEmbed']->getData();
if($agents)
{
$entity->setAgentLists(new ArrayCollection());
foreach($agents as $agent)
{
$entity->addAgentList($em->getRepository('AgentList')->find($agent->getId()););
}
}
$em->persist($entity);
$em->flush();
It's works for common Many-to-Many
