Question

我在这里做错什么了吗？我一直在尝试在Party上显示虚拟图像，而我只是尝试检查“口号”之类的简单虚拟图像。我也有人口问题。我有点讨厌这个cuz，它既不会抛出任何错误，也不会警告我，我也不知道它背后发生了什么。有点令人沮丧

   const mongoose = require('mongoose');
mongoose.set("debug", true);

const partySchema = mongoose.Schema({
   name: {
       type: String,
       required: [true, 'Please provide a party'],
       unique: [true, 'Party already exists. Please try another party name'],
       maxLength: [20, 'Party Name should be less than 20 characters'],
       minLength: [4, 'Party Name should be greater than 4 characters']
   },
   slogan:{
       type: String,
       required: [true, 'Please provide a slogan'],
       maxLength: [20, 'Party Name should be less than 20 characters'],
       minLength: [5, 'Party Name should be greater than 5 characters']
   },
   createdAt:{
       type: Date,
       default: Date.now()
   }
},{
   toObject: {
       virtuals: true
     }
     ,toJSON: {
       virtuals: true
     }
});

partySchema.virtual('slogans').get(function () {
   // use an ordinary function so you can get the "this"
   return this.slogan
});
