What is the current behavior?
When trying to set a default on an Array field, the default function doesn't give me access to the current object being created. I want to fill the array differently depending on the other values.
I found a similar issue #6263
But it is recommended to access pre-hooks, which I can't do. I need to have access to the default field.
Im using the latest version of mongoose (5.2.7).
Im using the same example as in the mongoose doc http://mongoosejs.com/docs/defaults.html#default-functions-and-this
I just added a field "actors" which is an array.
In releaseDate, I have access to this , but not in actors
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const schema = new Schema({
title: String,
released: Boolean,
releaseDate: {
type: Date,
default: function() {
console.log("releaseDate: ", this.released);
if (this.released) {
return Date.now();
}
return null;
}
},
actors: {
type: [
{
name: String,
age: Number
}
],
default: function() {
console.log("actors: ", this.released);
return [
{
name: "Test",
age: 20
}
];
}
}
});
const Movie = mongoose.model("Movie", schema);
const movie1 = new Movie({ title: "The Terminator", released: true });
const movie2 = new Movie({ title: "The Legend of Conan", released: false });
console.log(movie1);
