FeathersJS 生成器有错误吗？

Question

用feathersjs生成服务时，模型文件是这样的

import { Application } from '../declarations';

export default function (app: Application) {
  const modelName = 'comments';
  const mongooseClient = app.get('mongooseClient');
  const { Schema } = mongooseClient;
  const schema = new Schema({
    text: { type: String, required: true }
  }, {
    timestamps: true
  });

  // This is necessary to avoid model compilation errors in watch mode
  // see https://mongoosejs.com/docs/api/connection.html#connection_Connection-deleteModel
  if (mongooseClient.modelNames().includes(modelName)) {
    mongooseClient.deleteModel(modelName);
  }
  return mongooseClient.model(modelName, schema);
}

mongooseClient 是 Mongoose 类型，文档说 deleteModel 在 Connection.prototype.deleteModel()

下

该行不应该说 mongooseClient.connection.deleteModel(modelName); ??

Answer 1

不应该

如果您查看根文件夹下的文件 mongoose.js，您可以看到 'mongooseClient' 是在 mongoose.connect 之后设置的：

const mongoose = require('mongoose');

    module.exports = function (app) {
      mongoose.connect(
        app.get('mongodb'),
        { useCreateIndex: true, useNewUrlParser: true, useUnifiedTopology: true }
      );
      mongoose.Promise = global.Promise;
    
      app.set('mongooseClient', mongoose);
    };

所以它是 Connection.prototype 的一部分。
