由于父表上的外键违规，Sequelize 事务失败

Question

我有 3 个表：

1. 公司
2. 操作大师
3. 运营公司Xref

OperationCompanyXref是Company和OperationMaster的子表

协会是：

OperationsCompanyXref.belongsTo(Company, { foreignKey: 'companyId' });
OperationsCompanyXref.belongsTo(Operations, { foreignKey: 'operationId' });
Company.hasMany(OperationsCompanyXref, { foreignKey: 'companyId' });
Operations.hasMany(OperationsCompanyXref, { foreignKey: 'operationId' });

OperationMaster 已经有 1 个条目在创建新Company时，它应该插入到 2 个表中： Company ，然后是OperationsCompanyXref

Function 创建公司

    async function createCompany(companyObject) {
      let transaction = await db.sequelizeConnection.transaction();
      try {
        var createCompany = await db.Company.create(companyObject, { transaction })
    
        for (let i = 0; i < companyObject.operations.length; i++) {
          await db.OperationCompanyXref.create({
            operationId: companyObject.operations[i],
            companyId: createCompany.id,
            status : true
          },transaction);
        }
        await transaction.commit();
        return { createCompany };
      } catch (err) {
        console.error(err);
        await transaction.rollback();
        return err;
      }

问题：

code: 'ER_LOCK_WAIT_TIMEOUT', errno: 1205, sqlState: 'HY000', sqlMessage: '超过锁定等待超时； 尝试重新启动事务', sql: 'INSERT INTO OperationCompanyXrefs ( id , status , createdAt , updatedAt , companyId , operationId ) VALUES (DEFAULT,?,?,?,?,?);',

我注释掉插入OperationCompanyXrefs的代码，API调用成功插入Company。 手动插入 OperationCompanyXrefs 也能正常工作。

Answer 1

transaction选项应该在options object 中传递：

await db.OperationCompanyXref.create({
            operationId: companyObject.operations[i],
            companyId: createCompany.id,
            status : true
          },{ transaction });
