Mongoose没有为api / mlab保存数据

Question

I have a search api that you can search using the imgur api and it'll return json data of the images, but will also record your latest search in the "/latest" url. The only problem is it returns an empty array which leads me to believe my mlab database isn't saving anything despite having a save method.

Whole file: https://github.com/jeffm64/image-search-abstraction-layer

the code that may be not allowing it: index.js

        router.get("/latest", function (req, res) {
          History.find({}, 'term when -_id').sort('-when').limit(10).then(function (results) {
            res.json(results);
          });
        });

        router.get("/search/:q", function (req, res) {
          imgur.getImage(req.params.q, req.query.offset).then(function (ans) {
            new History({ term: req.params.q }).save();
            res.json(ans);
          });
        });

history.js

var historySchema = new mongoose.Schema({  term: String,  when: { type: Date, default: Date.now } });

var History = mongoose.model("History", historySchema);

Ok so the answer to this is super noob level. It wouldn't connect to the database because you made the user login for mlabs database read me only on accident. I guess I will leave this in case some other poor soul spends 15+ hours troubleshooting code that's probably fine!
