Mongoose schema nesting guide

I've encountered an issue while attempting to nest schemas in mongoose, and unfortunately I'm struggling to pinpoint the exact cause. Here's what my current setup looks like.

Starting with the parent schema:

const Comment = require("./Comment");

const BookSchema = new Schema({
  _id: Number,
  comments: [{ comment: Comment }],
  ratings: [{ rate: Number }],
  calculatedRating: Number
});

module.exports = Book = mongoose.model("book", BookSchema);

Now moving on to the child schema:


const CommentSchema = new Schema(
  {
    userName: String,
    rating: Number,
    body: String,
    submit_date: {
      type: Date,
      default: Date.now
    }
  },
  { _id: false }
);

module.exports = Comment = mongoose.model("comment", CommentSchema);

After setting up this structure, I'm encountering the following error:

"TypeError: Invalid schema configuration: Model is not a valid type at path comment."

I suspect that there might be an issue with how I exported these schemas, but I can't say for certain.

Answer №1

Your ./Response should read as follows:

const ResponseSchema = new Schema(
  {
    userName: String,
    rating: Number,
    body: String,
    submit_date: {
      type: Date,
      default: Date.now
    }
  },
  { _id: false }
);

module.exports = ResponseSchema;

If you define it as a new model like this, it will create its own collection and become a standalone model rather than a sub document schema.
