我正在尝试创建一个登录系统,管理员可以在其中登录并查看公众无法使用的数据。现在我只是想在我的数据库中找到我的管理实例。我有两个节点文件: app.js
和 account_manager.js
app.js
//creates node app
var express = require('express');
var app = express();
var mongoose = require('mongoose');
var AM = require('./account_manager');
//stuff...
/***************************************
LOGIN
***************************************/
app.post('/login', function(req, res){
AM.manualLogin(req.param('username'), req.param('password'), function(e, o){
if (!o){
res.send(e, 400);
} else{
req.session.user = o;
res.send(o, 200);
}
});
});
account_manger.js
需要app.js
并存储在 AM 中
account_manager.js
:
var express = require('express');
var app = express();
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost');
var admin_db = mongoose.connection;
admin_db.on('error', console.error.bind(console, 'connection error: '));
//connection open?
admin_db.once('open', function callback(){
console.log("User Database connection open!\n");
});
var User_Schema = new mongoose.Schema({username: String, password: String});
var Admin = mongoose.model('Admin', User_Schema);
exports.manualLogin = function(user, pass, callback)
{
admin_db.find({username: user},function(err,docs){ //error is here
if(docs){
var x = 0;
var flag = false;
while(docs[x]){ //goes through all the admins
if (docs[x].param("username") == user){ //if it's a match
callback(null, docs);
flag = true;
break;
}
x+=1;
}
if (flag == false){
callback('invalid-password/username');
}
}
});
}
我得到一个TypeError
说:
Object #<NativeConnection> has no method 'find'
我的问题是什么?
