Mongoose Not Saving Data

Question

I am having trouble with a simple query on my database. Following this tutorial: https://scotch.io/tutorials/build-a-restful-api-using-node-and-express-4 when Model.find() i

Answer 1

Exact same thing happened to me...

First two POSTs succeeded but did not post the data I was sending:

var p = new Post();
p.result = 'hello-world';

p.save(function (err) {});

Turned on debug mode: mongoose.set('debug', true); and next POST the field was saved...

Baffling!

Answer 2

For this code

post.title = req.body.title; // Set title (from request) post.content = req.body.content; // Set content (from request)

could you check

1. req.body.title and req.body.content are not undefined?

2. do you set the field in your Post schema as

   var PostSchema = new Schema({ title: String, content: String });

Answer 3

The problem is that you need to set the content-type while sending the post request as application/json otherwise the fields are not recognized.

Answer 4

I am beyond confused right now. It suddenly works, the code is the exact same as above. I am going to leave this open in case someone stumbles across it one day and can solve this mystery.

Answer 5

If you are using a manual tool like Postman to test your app, you must also put quotes around the key names in the body of your request, like {"key": "some string"}.

If you just put {key: "some string"} then the whole key/value pair is ignored when the document is saved to the database.

Answer 6

I experienced an error like this.

The problem was that I was loading the wrong mongoose Schema.

The result is that the only fields that are saved are those that are present in both schemas, i.e. _id and __v.
