为什么在这个脚本中mongoose的唯一性校验完全不起作用?
var child_process = require('child_process');
// Load required packages
child_process.exec("mongo test --eval 'db.users.drop();'", function(err){
var mongoose = require('mongoose');
console.log(mongoose.version);
mongoose.connect('mongodb://localhost:27017/test');
// Define our user schema
var json = {};
json.phone = { type: String, required: true, unique: true};
var UserSchema = new mongoose.Schema(json);
var Model = mongoose.model('user', UserSchema);
var jp = new Model({ phone: "123456"});
mongoose.connection.on('open', function(){
console.log(jp);
jp.save(function(err){
console.log(err);
var jp2 = new Model({ phone: "123456"});
console.log(jp2);
jp2.save(function(err){
console.log(err);
process.exit();
});
})
});
});
我很困惑,结果就像这样
3.8.20
{ phone: '123456', _id: 54856cceb5b40f7a88fcc2af }
null
{ phone: '123456', _id: 54856cceb5b40f7a88fcc2b0 }
null
感谢您的帮助。
