我正在尝试使用如下所示的destroy实例方法,但是我一直在接收NaN而不是删除的行数。
const Sequelize = require('sequelize');
const sequelize = new Sequelize(options);
const user = sequelize.define('user', {
firstName: {
type: Sequelize.STRING,
field: 'first_name' // Will result in an attribute that is firstName when user facing but first_name in the database
},
lastName: {
type: Sequelize.STRING
}
}
// insert some records with user object, etc
user.destroy({ truncate: true }).asCallback((err, deleted) => {
if (err) {
throw err;
}
console.log(deleted);
// Always prints NaN
});
任何帮助将不胜感激!

截断模型做类似的事情
var model = require('../models');
model.user.destroy({ truncate : true, cascade: false }).then(function(result)
{
res.json(result)
}).catch(function(err){
res.json(err)
})
或者如果要删除特定记录,请执行以下操作。如果不受影响,这将返回effected
或0
的行数
user.destroy({
where: {
email: "test@gmail.com"
}
})
.then(function (delete_rows) {
console.log(delete_rows);
res.json(delete_rows)
})
.catch(function (error){
res.status(500).json(error);
});
