我ng-pattern="/0-9/"用来设置price_field不接受decimal number.但是当我输入自然数(从0到9999999)时,ng-show会被激活Not valid number!.

我哪里做错了？.请帮忙.

<form name="myform" data-ng-submit="create()">
        <input type="number"
               name="price_field"
               data-ng-model="price"
               require
               ng-pattern="/0-9/"
        <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
        <input type="submit" class="btn">
</form>

我正在使用MongoDb和Nodejs.Nodejs托管在Heroku服务器上,Mongodb通过Heroku附加组件在MongoLab中托管.

安装MongoLab插件后,我收到了这个URI:

mongodb://<dbuser>:<dbpassword>@ds053148.mongolab.com:53148/heroku_app18934798

我不知道如何使用这个URI,请帮帮忙？在哪里放？什么是<dbuser>:<dbpassword

这是我的配置,它与mongoDB有关 locallhost

在 server.js

var env = process.env.NODE_ENV || 'development',
    config = require('./config/config')[env],
    mongoose = require('mongoose');

var db = mongoose.connect(config.db);

在 express.js

app.use(express.session({
            secret: 'thissecret',
            key:'express.sid',
            store: new mongoStore({
                url: config.db,
                collection: 'sessions'
            })
        }));

在 config.js

module.exports = {
    development: {
        db: 'mongodb://localhost/mean-dev',
        root: rootPath,
        app: {
            name: 'MEAN - A Modern Stack - Development'
        },
        facebook: {
            clientID: "APP_ID",
            clientSecret: "APP_SECRET",
            callbackURL: "http://localhost:3000/auth/facebook/callback"
        }

    },
    test: {
        db: 'mongodb://localhost/mean-test',
        root: rootPath,
        app: { …
