Sequelize外键约束格式错误

Question

我认为我没有做错任何事情。创建表时出现错误“外键约束格式错误”。我尝试了许多不同的方法，但是没有找到它。我无法解决错误的问题，请帮忙。

创建一个名为角色的表。（role.js）

'use strict';
module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.createTable('roles', {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.DataTypes.INTEGER,
      },
      roleName: {
        type: Sequelize.DataTypes.STRING,
        allowNull: false,
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY
      }
    });
  },
  down: async (queryInterface, Sequelize) => {
    await queryInterface.dropTable('roles');
  }
};

创建一个名为users（user.js）的表

'use strict';
module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.createTable('users', {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.DataTypes.INTEGER,
      },
      mail: {
        type: Sequelize.DataTypes.STRING,
        unique: true,
        allowNull: false,
      },
      password: {
        type: Sequelize.DataTypes.STRING,
       allowNull: false,
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY      }
    });
  },
  down: async (queryInterface, Sequelize) => {
    await queryInterface.dropTable('users');
  }
};

我无法创建名为用户角色的表。我收到上述错误。一切正常，我们还没有尝试过，没有解决办法。 userRole.js

'use strict';
module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.createTable('userRoles', {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.DataTypes.INTEGER
      },
      userID: {
        field: 'userID',
        type: Sequelize.INTEGER,
        references: {
          model: 'user',
          key: 'id'
        },
        onUpdate: 'CASCADE',
        onDelete: 'CASCADE',
      },
      roleID: {
        type: Sequelize.DataTypes.INTEGER,
        allowNull: false,
        references: {
          model: 'role',
          key: 'id'
        },
        onUpdate: 'CASCADE',
        onDelete: 'CASCADE',
      },
     
      createdAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DataTypes.DATEONLY
      }
    });
  },
  down: async (queryInterface, Sequelize) => {
    await queryInterface.dropTable('userRoles');
  }
};
