Mongoose if (!this.modelSchemas[name]) 错误

Mongoose if (!this.modelSchemas[name]) error

每当我尝试使用下面的代码连接时,

const mongoose = require('mongoose');
 
// var Model = mongoose.model.bind(mongoose); didnt work

var imageSchema = new mongoose.Schema({
 
  name: String,
  dob: String,
  breed: String,
  details: String,
    img:
    {
        data: Buffer,
        contentType: String
    }
 
});

module.exports = new mongoose.model('Image', imageSchema);

我在控制台中记录了这个错误

if (!this.modelSchemas[name]) {
                        ^

TypeError: Cannot read property 'Image' of undefined

我已经按照另一页的建议尝试了模型绑定猫鼬,但效果不佳

model是returns模型的一种方法。你不应该用 new:

来调用它
module.exports = mongoose.model('Image', imageSchema);
