Question

我想创建一个简单的节点博客，但我需要一些帮助！

我想将我的博客'条目'或'帖子'保存到rethinkdb，但要做到这一点我首先需要知道如何让我的帖子显示在我的博客上，所以我创建了一个rethinkdb服务器，带有一些条目！这就是它的样子：

[

    {
        "body": "This is the standard hello world message!" ,
        "id": "1" ,
        "published": "2014-04-19" ,
        "title": "Hello World!" 
    } ,
    {
        "body": "I tought dinner with my family would be horrific, but maybe my low expectations made it bearable" ,
        "id": "3" ,
        "published": "2014-04-19" ,
        "title": "Dinner was ok!" 
    } ,
    {
        "body": "Here I am ranting about how easter is not as awesome it is said to be" ,
        "id": "2" ,
        "published": "2014-04-19" ,
        "title": "Easter is hard work" 
    } 

]

数据库名称为'blogdb'，表名为'entries'

这是我的app.js（node.js服务器）

/**
 * Module dependencies.
 */

var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');

var app = express();

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

app.use(express.bodyParser());

// development only
if ('development' == app.get('env')) {
  app.use(express.errorHandler());
}

app.get('/', function(req, res) {
    res.render('index',
    {title: 'My Blog'}
    )
});

app.get('/about', function(req, res) {
    res.render('about',
    { title : 'About' }
    )
})

app.get('/photos', function(req, res) {
    res.render('photos',
    { title : 'Photos' }
    )
})

http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});

最后，我们有index.jade（网页）

extend layout
block content
    p this is where I want my entreis to be!
    footer
      p
        a(href='/') Home
        | ~
        a(href='/about') About Me
        | ~
        a(href='/photos') Some photos

我知道这并不多，但在我有参赛作品之前，我不想做太多的设计！

如何将rethinkdb服务器中的所有条目都放入我的网页？

所有帮助表示赞赏！

我个人使用sailsjs进行节点开发，所以我对具体表达并不了解......但......

你需要为初学者提供rethinkdb适配器......

var r = require('rethinkdb');

那么也许你可以把你的主页路线改成这样的......

app.get('/', function(req, res) {
    r.connect({host: 'rethinkdb_server_ip', db: 'blogdb'}, function(err, conn){
        r.table('entries').run(conn, function(err, cursor){
            if (err) {
                //Handle errors if you want.
            }
            cursor.toArray(function(entries){
                res.render('index', {entries: entries, title: 'My Blog'})
            });
        });
    });
});

从rethinkdb获取条目到node.js博客
