Use 'virtual' in an array of objects (Mongoose)-CodePudding

I have two schemas as the following:

const castListSchema = new Schema({
  id: String,
  roleInVideo: String
});

const videoSchema = new Schame({
  castList: { type: [castListSchema], default: [] }
});

I want to get data by the following structure:

castList: [
  {
    details: { ... },
    roleInVideo: 'director'

  },
  ...
]

I want to use virtual not aggregate and etc...

Is it possible? How?

CodePudding user response：

Yes, you can use the virtual function inside the array of objects.

Use the following code to use the virtual function for the array of objects.

videoSchema.virtual("castList.castData", {
  ref: "new_assets",
  localField: "castList.castListSchema",
  foreignField: "_id",
  justOne: true
});

In populate also use this "castList.castData" as key to retrieve the data.
