如何使用 sequelize 播种 uuidv4
How to seed uuidv4 with sequelize
我正在尝试使用 sequelize generate UUID 为 uuid 播种,但出现此错误 Seed file failed with error: sequelize.Utils.generateUUID is not a function TypeError: sequelize.Utils.generateUUID is not a function
我如何播种 UUID?
return queryInterface.bulkInsert('companies', [{
id: sequelize.Utils.generateUUID(),
name: 'Testing',
updated_at: new Date(),
created_at: new Date()
}]);
只需安装 uuid:
npm install uuid
在你的种子文件上:
const uuidv4 = require('uuid/v4');
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.bulkInsert('yourTableName', [
{
id: uuidv4()
}],
{});
因为它包含在 DataTypes
包中,所以按照 Matt 的建议使用 already available 是有意义的。你可以这样使用它:
{
...,
type: DataTypes.UUID,
defaultValue: DataTypes.UUIDV4,
...
}
npm install uuid
将其导入您的种子文件
const { v4: uuidv4 } = require('uuid');
return queryInterface.bulkInsert('companies', [{
id: uuidv4(),
name: 'Testing',
updated_at: new Date(),
created_at: new Date()
}]);
