sequelize index 选项运行两次并导致测试失败

Question

这是我的模型：


var PaymentsToMonths = db.define('PaymentsToMonths', {
    id: {
        type: DataTypes.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },
    PaymentPlanDetailID: {
        type: Sequelize.DECIMAL,
        allowNull: false,
    },
    month: {
        type: Sequelize.DECIMAL,
        allowNull: false,
        // todo add validation 1-12
    },
    year: {
        type: Sequelize.DECIMAL,
        allowNull: false,
    },
    sum: {
        type: Sequelize.DECIMAL,
        allowNull: false,
    },
    monthTotal: {
        type: Sequelize.DECIMAL,
        allowNull: false,
    }
    
}, {
    tableName: 'PaymentsToMonths',
    freezeTableName: true, // Model tableName will be the same as the model name
    timestamps: true,
    indexes: [
        {
            unique: true,
            fields: ['PaymentPlanDetailID', 'month', 'year'],
            name: 'unique_payment_per_month_and_year'
        }
    ]
})

当运行测试时我看到这个错误：

  console.error
    SequelizeDatabaseError: Duplicate key name 'unique_payment_per_month_and_year'

这是由于运行这两个相同的行：

  console.log
    Executing (default): ALTER TABLE `PaymentsToMonths` ADD UNIQUE INDEX `unique_payment_per_month_and_year` (`PaymentPlanDetailID`, `month`, `year`)

      at Sequelize.log (../node_modules/sequelize/lib/sequelize.js:1171:15)

  console.log
    Executing (default): ALTER TABLE `PaymentsToMonths` ADD UNIQUE INDEX `unique_payment_per_month_and_year` (`PaymentPlanDetailID`, `month`, `year`)

为什么会这样？

不确定是否相关，但我也有这段代码用于测试：

afterAll(async (done) => {
    jest.restoreAllMocks();

    // remove all data and tables
    await sequelize.drop();

    // to end the jest process
    done();

})

原来是因为使用了

sequelize.sync({force: false})

在我的 main_test.js 文件中。

愚蠢的错误..

删除其中一个有效。

sequelize index option runs twice and causes test to fail
