How to get data from existing MongoDB database?

Question

I have a database on mlab and now I was starting a new Project and trying to simply get data from there.

The Database has only one collection called Article.

On my Node js project, using Mongoose, I created the Model for it:

var mongoose = require('mongoose');

var articleSchema = new mongoose.Schema({
  title: { type: String, required: true },
  body: { type: String }
});

var Article = mongoose.model('Article', articleSchema);

module.exports = Article;

The in my controller I just did this:

Article.find({}, function (err, articles) {
    res.send(articles);
});

I should receive more than 300 articles but the response is just an empty Array.

I was wondering if I need to run a few more command in order to connect to the db correctly, but I don't know it...

you have var Article = mongoose.model('Article', articleSchema);, but you define article, not articleSchema, one line above. Can this be the issue? — Tudor Constantin

Do you get any errors while connecting (code not presented)? Maybe you are connecting to a different uri and therefore the articles collection is empty? — Andrey Popov

If you want to fetch on an existing Article collection:

var articleSchema = new mongoose.Schema({
  title: { type: String, required: true },
  body: { type: String }
}, { collection : 'Article' });

This is just a more complicated version of the very same code. I don't know how this answers any problem?

No I think { collection : 'Article' } solves the problem.

Yes, it was enough to write to add { collection : 'Article' } to answer my question, it should be better to edit the answer to better fit the question. Thanks.

Oh now I get it. Good catch Thomi! You just should've answered it straightly that there's a typo/difference in the collection name, rather than writing code for separate files. Anyways, good work!
