如何使用 sequelize 和 postgres 批量插入

Question

在这里，我尝试在我的 sequelize db 中插入批量数据，但它会产生问题。 如何在angularjs中使用sequelize和postgres批量插入？

首先使用sequelize seed:create --name nameofseed创建种子文件，它将在你的根目录中创建种子文件夹，在config.js的development:{seederStorage:'sequelize'}中添加seederStorage:'sequelize' 在这里给表名是offer，但在db中它是offers和json对象中的表字段。 创建播种机后，它需要分别migrate 和run。 这是运行种子的命令：sequelize db:seed:all，然后运行迁移命令：sequelize db:migrate 就是这样。

 module.exports = {
      up: function(queryInterface, Sequelize) {
        queryInterface.bulkInsert('offers', [{
          ban: [1],
          sDate: '2016-03-31T08:00:10.354Z',
          eDate: '2016-03-31T08:00:10.354Z',
          isActive: true,
          reminder: false,
          sold: false,
          couponFor: 'Coupon Code',
          couponVal: 'Flat20%',
          createdAt: '2016-03-31T08:00:10.354Z',
          updatedAt: '2016-03-31T08:00:10.354Z'
        },
        {
          ban: [1, 2],
          sDate: '2016-03-31T08:00:10.354Z',
          eDate: '2016-03-31T08:00:10.354Z',
          isActive: true,
          reminder: false,
          sold: false,
          couponFor: 'Coupon Code',
          couponVal: 'Flat40%',
          createdAt: '2016-03-31T08:00:10.354Z',
          updatedAt: '2016-03-31T08:00:10.354Z'
        },
        {
          ban: [1, 2],
          sDate: '2016-03-31T08:00:10.354Z',
          eDate: '2016-03-31T08:00:10.354Z',
          isActive: true,
          reminder: false,
          sold: false,
          couponFor: 'Coupon Code',
          couponVal: 'Flat60%',
          createdAt: '2016-03-31T08:00:10.354Z',
          updatedAt: '2016-03-31T08:00:10.354Z'
        },
        {
          ban: [1],
          sDate: '2016-03-31T08:00:10.354Z',
          eDate: '2016-03-31T08:00:10.354Z',
          isActive: true,
          reminder: false,
          sold: false,
          couponFor: 'Coupon Code',
          couponVal: 'Flat100%',
          createdAt: '2016-03-31T08:00:10.354Z',
          updatedAt: '2016-03-31T08:00:10.354Z'
        }], {});
        /*
          Add altering commands here.
          Return a promise to correctly handle asynchronicity.

          Example:
          return queryInterface.bulkInsert('Person', [{
            name: 'John Doe',
            isBetaMember: false
          }], {});
        */
      },

      down: function(queryInterface, Sequelize) {
        /*
          Add reverting commands here.
          Return a promise to correctly handle asynchronicity.

          Example:
          return queryInterface.bulkDelete('Person', null, {});
        */
      }
    };
