Question

这是我在symfony 3.4中更新架构时遇到的错误。当我将第二个类中的referencedColumnName更改为第一个类的id时，它不会出错。但当我把它改成＆＃34; costmodelinternal_name＆＃34;第一个类中的变量，它会给我以下错误。

In AbstractMySQLDriver.php line 121:

  An exception occurred while executing 'ALTER TABLE cost_model_internal ADD CONSTRAINT FK_F59CC1232B401EC6 FOREIGN K
  EY (costmodelinternal_name) REFERENCES bonus_calculation_1 (costmodelinternal_name)':

  SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint


In PDOConnection.php line 106:

  SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint


In PDOConnection.php line 104:

  SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint


doctrine:schema:update [--complete] [--dump-sql] [-f|--force] [--em [EM]] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction] [-e|--env ENV] [--no-debug] [--] <command>

这是类相关字段（一对多）关系

class BonusCalculation1
{
    /**
     * @ORM\OneToMany(targetEntity="CostModelInternal", mappedBy="bonus_calculation1")
     */
    private $cost_model_internals;

    public function __construct() {
        $this->cost_model_internals = new ArrayCollection();
    }
}

class CostModelInternal
{
     /**
     * @ORM\ManyToOne(targetEntity="BonusCalculation1", inversedBy="cost_model_internals")
     * @ORM\JoinColumn(name="costmodelinternal_name", referencedColumnName="costmodelinternal_name")
     */
    private $bonus_calculation1;
}

提前感谢您的帮助

实际上我正在尝试使用没有主键属性来构建关系。在学说中不允许这样做

字符串外键的Doctrine错误
