问题描述
所以我设法让这个工作与用户和工作之间的关系
我遵循完全相同的过程,检查文档,我失去了
我正在设置的关系是工作工作
1分配了许多工作项的作业
../ Entity / Job.php
**
* @ ORM\OneToMany(targetEntity =Work,mappedBy =workJob)
*
* /
protected $ jobToWork;
/ **
*添加jobToWork
*
* @param \Laelaps\InvoiceBundle\Entity\Work $ jobToWork
* @return作业
* /
public function addJobToWork(\Laelaps\InvoiceBundle\Entity\Work $ jobToWork)
{
$ this-> jobToWork [] = $ jobToWork;
return $ this;
}
/ **
*删除jobToWork
*
* @param \Laelaps\InvoiceBundle\Entity\Work $ jobToWork
* /
public function removeJobToWork(\Laelaps\InvoiceBundle\Entity\Work $ jobToWork)
{
$ this-> jobToWork-> removeElement($ jobToWork);
}
/ **
*获取jobToWork
*
* @return \Doctrine\Common\Collections\Collection
* /
public function getJobToWork()
{
return $ this-> jobToWork;
}
../ Entity / Work.php
/ **
* @ ORM\ManyToOne(targetEntity =Job,inversedBy =jobToWork)
* @ ORM\\ \\ JoinColumn(name =work_job,referencedColumnName =id)
* /
protected $ workJob;
/ **
*设置workJob
*
* @param integer $ workJob
* @return工作
* /
public function setWorkJob($ workJob)
{
$ workJob-> addJobToWork($ this);
$ this-> workJob = $ workJob;
return $ this;
}
/ **
* Get workJob
*
* @return integer
* /
public function getWorkJob )
{
return $ this-> workJob;
}
我做了一个应用程序/控制台原则:generate:crud
我知道为我的用户工作的工作关系设置完全一样。
当我尝试去创建一个新的工作项目时,我得到的错误是
类.. \Entity\Job的对象不能转换为字符串
任何帮助,一如既往的非常赞赏
更新 / p>
如答案中所定义
public function __toString()
{
return(string)$ this-> getJobName();
}
当我使用FOSUserBundle和我的用户类扩展FOSUser类时,这意味着__toString()函数在FOSUser中定义,因此在向用户创建关联时没有问题。
您可能会尝试将作业显示为字符串(例如在选择框或列表中)。只需向Job实体添加一个__toString()方法,如下所示:
public function __toString()
{
return $ this-> name; //例如
}
Hi so I managed to get this working for a relationship between users and a Job
I followed exactly the same procedure, checked the documentation and I am at a loss
The relationship i'm trying to set up is Job to work
1 Job with many work items assigned to it
../Entity/Job.php
/**
* @ORM\OneToMany(targetEntity="Work",mappedBy="workJob")
*
*/
protected $jobToWork;
/**
* Add jobToWork
*
* @param \Laelaps\InvoiceBundle\Entity\Work $jobToWork
* @return Job
*/
public function addJobToWork(\Laelaps\InvoiceBundle\Entity\Work $jobToWork)
{
$this->jobToWork[] = $jobToWork;
return $this;
}
/**
* Remove jobToWork
*
* @param \Laelaps\InvoiceBundle\Entity\Work $jobToWork
*/
public function removeJobToWork(\Laelaps\InvoiceBundle\Entity\Work $jobToWork)
{
$this->jobToWork->removeElement($jobToWork);
}
/**
* Get jobToWork
*
* @return \Doctrine\Common\Collections\Collection
*/
public function getJobToWork()
{
return $this->jobToWork;
}
../Entity/Work.php
/**
* @ORM\ManyToOne(targetEntity="Job",inversedBy="jobToWork")
* @ORM\JoinColumn(name="work_job", referencedColumnName="id")
*/
protected $workJob;
/**
* Set workJob
*
* @param integer $workJob
* @return Work
*/
public function setWorkJob($workJob)
{
$workJob->addJobToWork($this);
$this->workJob = $workJob;
return $this;
}
/**
* Get workJob
*
* @return integer
*/
public function getWorkJob()
{
return $this->workJob;
}
I did a app/console doctrine:generate:crud
Which I know worked for my user to job relationship which was set up exactly the same way.
the error I get when I try to go to create a new "work" item is Object of class ..\Entity\Job could not be converted to string
Any help, as always greatly appreciated
UPDATE
As defined in the answer
public function __toString()
{
return (string) $this->getJobName();
}
As I was using the FOSUserBundle and my user class extended the FOSUser class this meant that the __toString() function was defined in the FOSUser, hence there was no problem when creating assocations to user.
You probably try to display your Job as a string (inside a select box or a list for example). Just add a __toString() method to your Job entity like this :
public function __toString()
{
return $this->name; // For example
}
