組織員工 org_employees

所以我在下面的方式聯繫起來entoties。

員工 - 一對多 - OrgEmployee（鏈接表） - 多對一

但我得到以下錯誤：

An exception occurred while executing 'INSERT INTO org_branch_employees (is_active, created_at, created_by, modified_at, modified_by, employee_id, org_branch_id) VALUES (?, ?, ?, ?, ?, ?, ?)' with params [\"1\", \"2016-02-04 20:03:22\", 1, \"2016-02-04 20:03:22\", 1, null, null]:\n\nSQLSTATE[23000]: Integrity constraint violation: 1048 Column 'employee_id' cannot be null"

我很沮喪，我哪裏錯了，任何人都可以幫助我。

仔細看看OrgEmployee中的目標實體。複製/粘貼問題。 – Cerad

@Cerad感謝您的評論，我已更改 – user3929758

有一個在OrgEmployee實體的問題，應該是setEmployee（）和setOrganization（），並且我有$ this-> employees而不是$ this-> employee

class OrgEmployee extends BaseEntity{ 

     /** 
     * @ORM\ManyToOne(targetEntity="Employee\Entity\Employee", inversedBy="orgEmployee") 
     * @ORM\JoinColumn(name="employee_id",referencedColumnName="id",nullable=false) 
     */ 
     protected $employee; 

     /** 
     * @ORM\ManyToOne(targetEntity="Organization\Entity\Organization", inversedBy="orgEmployee") 
     * @ORM\JoinColumn(name="org_branch_id", referencedColumnName="id", nullable=false) 
     */ 
     protected $organization; 

     public function setEmployee(Employee $employee = null) 
     { 
      $this->employee = $employee; 

     return $this; 
    } 

    public function getEmployee() 
    { 
     return $this->employee; 
    } 

    public function setOrganization(Organization $organization = null) 
    { 
     $this->organization = $organization; 

     return $this; 
    } 

    public function getOrganization() 
    { 
     return $this->organization; 
    }  


}

我明白，組織有許多員工和員工可以屬於許多組織。你不需要創建新的實體。它應該是這樣的：

Employee類

/** 
* @var Organization | ArrayCollection 
* 
* @ORM\ManyToMany(targetEntity="Organization\Entity\Organization", mappedBy="employees") 
*/ 
protected $organizations; 

/** 
* @return ArrayCollection|Organization 
*/ 
public function getOrganizations() 
{ 
    return $this->organizations; 
} 

/** 
* @param Organization $organization 
* @return $this 
*/ 
public function addOrganization(Organization $organization) 
{ 
    if (!$this->organizations->contains($organization)) { 
     $this->organizations->add($organization); 
    } 

    return $this; 
} 

/** 
* @param Organization $organization 
* @return $this 
*/ 
public function removeOrganization(Organization $organization) 
{ 
    if ($this->organizations->contains($organization)) { 
     $this->categories->removeElement($category); 
    } 

    return $this; 
}

組織CLASS

/** 
* @var Employee | ArrayCollection 
* 
* @ORM\ManyToMany(targetEntity="Employee\Entity\Employee", inversedBy="organizations") 
* @ORM\JoinTable(name="org_employees", 
*  joinColumns={@ORM\JoinColumn(name="organization_id", referencedColumnName="id")}, 
*  inverseJoinColumns={@ORM\JoinColumn(name="employee_id", referencedColumnName="id")} 
*  ) 
*/ 
protected $employees; 

getter, add, remove methods here..

當心在我的代碼中的錯誤（我很快就寫了這個） - 它應該是唯一的概念展示。

鏈接表中有一個額外的列，所以我coulnt以這種方式做 – user3929758

好吧，不幸的是，我不能在鏈接表中的示例額外的列中看到。返回錯誤=>您嘗試在鏈接表中爲** employee_id **列添加** null **的新記錄。這個列不能爲空 - 你能告訴我代碼負責創建這個**插入**嗎？ – LuckyLue
