As documents returned by mongoose

  • 772

I am trying to manipulate a document that returns a query to mongoDB through mongoose but I manage to get it. I am developing with Node.js with Koa framework and Mongoose as ODM.

The code is :

const Router = require('koa-router');
const RestaurantModel = require('models/restaurant.model');

class RestaurantRouter{

    static async get(ctx,next){
        ctx.body = await RestaurantModel.find();
    }

    static async getById(ctx){
        ctx.body='get';
    }
}

const router = new Router({prefix:'/restaurant'});

router.get('/', RestaurantRouter.get);
router.get('/:id', RestaurantRouter.getById);

module.exports = router;

I would need to be able to manipulate the document that RestaurantModel.find(); and embed it inside another larger document and send it to the response body, something like

ctx.body = await {feature : RestaurantModel.find()};

I can't find a way since RestaurantModel.find() doesn't return the document itself but a Query object from which I can't get the document.

Any suggestion?

Thank you!

    In Koa, the Content-Type is implicit according to the value you assign to ctx.body. In your case, you must assign an object to it so that it returns a JSON. I don't see any problem in your case, except for architectural details. You just need to wrap what the model returns in another object:

    ctx.body = {
  feature: await RestaurantModel.find()
};

    Which will produce a response like.

    {
  "feature": [
    { ... },
    { ... },
    { ... }
  ]
}
