sequelize.js - Sequelize 运行迁移无法添加外键约束

Question

我创建了两个模型。在我想为他们创建迁移之后。
配置模型。该配置将“hasMany”与域相关联。一个配置可以与多个域相关。

const { Model } = require('sequelize');
module.exports = (sequelize, DataTypes) => {
    class Config extends Model {
        static associate(models) {
            Config.hasMany(models.domain, {
                foreignKey: 'configId',
                onDelete: 'CASCADE',
            });
        }
    }

    Config.init(
        {
            id: {
                allowNull: false,
                autoIncrement: true,
                primaryKey: true,
                type: DataTypes.INTEGER,
            },
            country: {
                type: DataTypes.STRING,
                allowNull: false,
            },
        },
        {
            sequelize,
            tableName: 'configs',
            modelName: 'config',
            timestamps: false,
        },
    );
    return Config;
};

配置模型。该域具有与配置相关的“belongsTo”。一个域可以与一个配置相关。

const { Model } = require('sequelize');
module.exports = (sequelize, DataTypes) => {
    class Domain extends Model {
        static associate(models) {
            Domain.belongsTo(models.config, {
                foreignKey: 'configId',
            });
        }
    }

    Domain.init(
        {
            id: {
                allowNull: false,
                autoIncrement: true,
                primaryKey: true,
                type: DataTypes.INTEGER,
            },
            domain: {
                type: DataTypes.STRING,
                allowNull: false,
            },
            isActive: {
                type: DataTypes.BOOLEAN,
                allowNull: false,
                defaultValue: false,
            },
        },
        {
            sequelize,
            tableName: 'domains',
            modelName: 'domain',
            timestamps: false,
        },
    );
    return Domain;
};

在我创建了两个迁移之后。
配置迁移。

module.exports = {
    up: async (queryInterface, Sequelize) => {
        await queryInterface.createTable('configs', {
            id: {
                allowNull: false,
                autoIncrement: true,
                primaryKey: true,
                type: Sequelize.INTEGER,
            },
            country: {
                type: Sequelize.STRING,
                allowNull: false,
            },
        });
    },

    down: async (queryInterface, Sequelize) => {
        await queryInterface.dropTable('configs');
    },
};

域迁移

module.exports = {
    up: async (queryInterface, Sequelize) => {
        await queryInterface.createTable('domains', {
            id: {
                allowNull: false,
                autoIncrement: true,
                primaryKey: true,
                type: Sequelize.INTEGER,
            },
            domain: {
                type: Sequelize.STRING,
                allowNull: false,
            },
            isActive: {
                type: Sequelize.BOOLEAN,
                allowNull: false,
                defaultValue: false,
            },
            configId: {
                type: Sequelize.INTEGER,
                onDelete: 'CASCADE',
                references: {
                    model: 'configs',
                    key: 'id',
                },
            },
        });
    },

    down: async (queryInterface, Sequelize) => {
        await queryInterface.dropTable('domains');
    },
};

然后我运行我的迁移并出现错误。

user@user-ps:~/Documents/projects/app-api$ npm run migration:run

> app-api@1.0.0 migration:run
> sequelize db:migrate

我哪里做错了？我想创建迁移然后我可以运行或反转。

“迁移”路径中的JS文件顺序问题:
在生成“域”表之前，生成“配置”表。
