Tengo 2 colecciones: Categoría y libro.

Libro:

 const mongoose = require('mongoose'); // eslint-disable-next-line camelcase const mongoose_delete = require('mongoose-delete'); const { Schema } = mongoose; const SchemaTypes = mongoose.Schema.Types; const Book = new Schema({ name: { type: String }, price: { type: Number }, images: { type: Array }, country: { type: String }, author: { type: String }, publicationDate: { type: String }, description: { type: String }, category: { type: SchemaTypes.ObjectId, ref: 'Category' }, date: { type: Date, default: Date.now }, }, { timestamps: true, }); Book.plugin(mongoose_delete); Book.plugin(mongoose_delete, { overrideMethods: 'all', deletedAt: true }); module.exports = mongoose.model('Book', Book);

Categoría:

 const mongoose = require('mongoose'); // eslint-disable-next-line camelcase const mongoose_delete = require('mongoose-delete'); const SchemaTypes = mongoose.Schema.Types; const { Schema } = mongoose; const Category = new Schema({ name: { type: String, required: true }, image: { type: String }, products: [{ type: SchemaTypes.ObjectId, ref: 'Book' }], date: { type: Date, default: Date.now }, }, { timestamps: true, }); Category.plugin(mongoose_delete); Category.plugin(mongoose_delete, { overrideMethods: 'all', deletedAt: true }); module.exports = mongoose.model('Category', Category);

y selecciono todos los libros recibidos de la lista:

 { _id: new ObjectId("623668ac5b1d392b37690cbc"), name: 'The Godfather', price: 110000, country: 'U.S', publicationDate: '1969', category: new ObjectId("6238fdf64f60303756b60b20"), author: 'Mario Puzo', ... : ... }

Y quiero mostrar el nombre de la categoría en la lista de productos, ¿cómo lo hago? **como: {{book.category.name}}

{{libro.categoría.imagen}}
