File uploading not working

[Antonded]

My schema is
var NewsItemSchema = new Schema({
title: {type: String, required: true},
date: {type: Date, required: true, default: new Date()},
subtitle: {type: String, required: false},
images: {type: Schema.Types.File, upload_to: __dirname + '/../public/uploads/'},
text:{type: String, required: true},
state:{type: String, enum: ['current', 'archive', 'draft', 'personal']}
});

but nothing happens, in browser's POST request is no field containing my file. In Webstorm debugger i can't see that FileField pre_precess function works, but nothing happens. my App.js:

'use strict';

var mongoose = require('./models/mongoose').mongoose;

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var log = require('./libs/log')(module);
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var passport = require('passport');
var config = require('./libs/config');
var session = require('express-session');
var methodOverride = require('method-override');
var multer = require('multer');
var MongoStore = require('connect-mongo')(session);

require('./libs/passport.js');

var app = express();
var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(cookieParser());
app.use(methodOverride());
app.use(bodyParser.json());
app.use(multer({ dest: __dirname + '/private/uploads/'}));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));

var formage = require('formage').init(app, express, mongoose.models, {
title: 'Экономическая олимпиада имени Кондратьева',
root: '/formage',
default_section: 'main',
admin_users_gui: true
});

app.use(session({
secret: "hidden",
proxy: true,
resave: true,
saveUninitialized: true,
store:new MongoStore({db: 'kondrat-olymp'})
}));

app.use(passport.initialize());
app.use(passport.session());

and forage can't find socket.io.js, i've added it manually but it can't establish connection
