Question

我正在尝试在此表上插入新数据（使用继承）：

Entity\AbstractSurveyAnswer:
    type: entity
    table: survey_answers
    inheritanceType: JOINED
    discriminatorColumn:
        name: type_class
        type: string
    discriminatorMap:
        database: SurveyDatabaseAnswer
        client_text: SurveyClientTextAnswer
        client_number: SurveyClientNumberAnswer
        client_date: SurveyClientDateAnswer

    id:
        id:
            type: integer
            generator:
                strategy: AUTO

    manyToOne:
        client:
            targetEntity: Entity\Client
            joinColumn:
                name: id_client
                nullable: false
                referenceColumnName: id

        survey:
            targetEntity: Entity\AbstractSurvey
            joinColumn:
                name: id_survey
                nullable: false
                referenceColumnName: id

和

Entity\SurveyDatabaseAnswer:
    type: entity
    table: survey_database_answers

    indexes:
        id:
            columns: [id, id_answer]

    manyToOne:
        answer:
            targetEntity: Entity\Answer
            joinColumn:
                name: id_answer
                nullable: false
                referenceColumnName: id

我以这种方式更新表，并且它起作用（有一些省略的代码和一些诸如flush的学说功能封装在另一个类上）

$updated_answer = new SurveyDatabaseAnswer();
$updated_answer->setId($result[0]);
$updated_answer->setClient($client);
$updated_answer->setSurvey($survey);
$updated_answer->setAnswer($answer);
$storage->merge($updated_answer);
$storage->flush();

但是如果我尝试插入新行

$updated_answer = new SurveyDatabaseAnswer();
$updated_answer->setClient($client);
$updated_answer->setSurvey($survey);
$updated_answer->setAnswer($answer);
$storage->persist($updated_answer);
$storage->flush();

我收到此错误，教义试图插入和存在的ID

Type: Doctrine\DBAL\Exception\UniqueConstraintViolationException

Message: An exception occurred while executing 'INSERT INTO survey_database_answers (id, id_answer) VALUES (?, ?)' with params [7438572, 1888]: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '7438572' for key 'PRIMARY'

我在教义上犯错了吗？
