我有这些代码运行尝试将对象保存到MongoDB中.
该.save()从来没有成功运行.代码运行正常.
.save()方法不起作用.
var conn = mongoose.createConnection(mongoUrl, {auth: {authdb: "admin"}});
conn.on('error', function (err) {
throw err;
});
conn.once('open', function callback() {
console.log("connected to " + mongoUrl);
var cacheSchema = mongoose.Schema({}, {strict: false});
cacheSchema.set('collection', 'caches');
// you need to specify which connection is uing.
var Cache = conn.model('cache', cacheSchema);
var measure = new Cache();
measure['test'] = "test";
measure.save(function(err){
console.log('test');
});
});
