simple node api request don't display any data

Look I have request in my server.js file

var Post = require('./../models/post');
//GET ALL POSTS
app.get('/api/posts', function (req, res) {
    Post.getPosts(function (err, posts) {
        if(err) {
            throw err;
        }
        res.json(posts);
    });
});

and my post.js model looks like this:

var mongoose = require('mongoose');

var postSchema = mongoose.Schema({
    username: {
        type: String,
        required: true
    },
    body: {
        type: String,
        required: true
    },
    date: { type: Date,
        default: Date.now
    }
});

var Post = module.exports = mongoose.model('Post', postSchema);

// Get All Posts
module.exports.getPosts = function (callback, limit) {
    Post.find(callback).limit(limit);
};

In my eye all code is written right but it does not display data so I double check the mongoDB if i have any record there:

> show dbs
admin      0.000GB
bookstore  0.000GB
local      0.000GB
ownfb      0.000GB
> use ownfb
switched to db ownfb
> show collections
posts
> db.posts.find()
{ "_id" : ObjectId("597aa5b04c08c647b4efb58d"), "type" : "user", "body" : "POST_Z_MONGOOSE_YO" }

MongoDB looks good and contains one record so why when I go to url http://localhost:5000/api/posts

It shows nothing except empty array

[]

Also I do not get any error in cmd/browser.

Gist full code of those 2 files:

app.get('/api/posts', function (req, res) { Post.getPosts(function (err, posts) { res.json(posts); res.end(); // !!!!! }); // returns here with no results });

Please note the res.end() function that must be called after res.json() to actually transfer the data.

You're not passing in the correct parameters into your getPosts() function. It's expecting callback and limit... I bet it's using 0 as the limit since you're not giving it any.

OR

You could try only having one export. postSchema.getPosts() is where you could attach the method and then just export mongoose.model('Post', postSchema); and nothing else.
