无法添加外键约束 - SEQUELIZE

Question

我认为像这样的错误应该与字段类型（数据类型）不匹配有关。但这已被证明是错误的，因为我已尝试将 table id 和外键的数据类型更改为整数和 uuid，但结果仍然相同。我还想指出 nodejs 是全新的，所以你知道我来自哪里......

migration/xxxxxxx-demo-user.js

'use strict';
module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.createTable('Users', {
      id: {
        type: Sequelize.UUID,
        defaultValue: Sequelize.UUIDV4,
        allowNull: false,
        primaryKey: true
      },
      firstName: {
        type: Sequelize.STRING
      },
      lastName: {
        type: Sequelize.STRING
      },
      email: {
        type: Sequelize.STRING
      },
      phoneNumber: {
        type: Sequelize.STRING
      },
      country: {
        type: Sequelize.STRING
      },
      PlanId: {
        type: Sequelize.UUID,
        references: {
            model: 'Plans',
            key: 'id'
        },
        onUpdate: 'CASCADE',
        onDelete: 'SET NULL',
      },
      password: {
        type: Sequelize.STRING
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DATE
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE
      }
    });
  },
  down: async (queryInterface, Sequelize) => {
    await queryInterface.dropTable('Users');
  }
};

migrations/xxxxxx-demo-plan.js

'use strict';
module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.createTable('Plans', {
      id: {
        type: Sequelize.UUID,
        defaultValue: Sequelize.UUIDV4,
        allowNull: false,
        primaryKey: true
      },
      title: {
        type: Sequelize.STRING
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DATE
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE
      }
    });
  },
  down: async (queryInterface, Sequelize) => {
    await queryInterface.dropTable('Plans');
  }
};

Answer 1

尝试重命名您的“xxxxxxx-demo-user.js”和“xxxxxxx-demo-plan.js”迁移文件名。一开始您在计划迁移之前进行了运行用户迁移，这就是为什么您的“planId”字段（用户 table）指向不存在的计划 table。尝试这样的操作，然后运行再次迁移：

20210918101111-demo-plan.js
20210918102222-demo-user.js

sequelize db:migrate:undo:all
sequelize db:migrate
