Question

我有一个场景，我将链接以下表格：

组织雇员 org_employees

所以我用以下方式链接这些行为。

员工 - OneToMany - OrgEmployee（链接表） - ManyToOne

但我收到以下错误：

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"

我很沮丧，我错了，任何人都可以帮助我。

    public function getOrganizations()
    {
        return $this->organizations;

}

Answer 1

OrgEmployee实体存在问题，应该是setEmployee（）和setOrganization（），我有$ this-＆gt;员工而不是$ this-＆gt;员工

    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;
    }    


}

Answer 2

据我所知，组织有很多员工，员工可以属于很多组织。您不需要创建新实体。它应该是这样的：

员工人数

/**
 * @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;
}

组织类

/**
 * @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..

注意我的代码中的错误（我快速写了这篇文章） - 它应该只显示概念。
