Generate function static values not being inserted.

[AnthonyConklin]

Problem:

const data = DataFactory.createForClass(Message).generate(1, {
  body: 'Test this overwrites'
});
// Output { "body": "Exercitationem rerum ab quae libero nobis debitis deleniti iusto aut." }
// Expected { "body": "Test this overwrites" }

// message.schema.ts

import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose';
import { Date, Document, Types } from 'mongoose';
import { Factory } from 'nestjs-seeder';
import { Chat } from 'src/chats/chat.schema';
import { User } from 'src/users/user.schema';

@Schema()
export class MessageHistory {
  @Prop({ default: '' })
  message: string;

  @Prop({ type: Date, default: Date.now })
  timestamp: Date;
}
// Generate a Mongoose Schema before use as Subdocument
const MessageHistorySchema = SchemaFactory.createForClass(MessageHistory);

@Schema({
  timestamps: true,
  toJSON: {
    virtuals: true
  }
})
export class Message {
  @Prop({ type: String, ref: 'User' })
  user: User;

  @Prop({ type: Types.ObjectId, ref: 'Chat', index: true })
  chat: Chat;

  @Factory((faker) => faker.lorem.sentence())
  @Prop({ default: '' })
  body: string;

  @Prop({ type: Date, default: undefined })
  deletedAt: Date;

  @Prop({ type: [MessageHistorySchema] })
  editHistory: MessageHistory[];
}

export type MessageDocument = Message & Document;

export const MessageSchema = SchemaFactory.createForClass(Message);

MessageSchema.virtual('edited').get(function (this: MessageDocument) {
  return this.editHistory.length > 0;
});
