Mongoose錯誤MissingSchemaError：尚未在打字稿中為模型注冊模式

花費大量時間在互聯網上進行研究。在這種情況下，我無法找出我遺漏了什么。請幫助我，非常感謝！

Permission.ts（這是 Permission 模型檔案。它通過“ModelID”與 Module 模型具有參考）

import mongoose from 'mongoose';

// An interface that describes the properties
// that are requried to create a new User
interface PermissionAttrs {
  Code: string;
  Name: string;
  Description: string;
  ModuleID: string;
  Active: boolean;
  CreatedByUserID: string;
  UpdatedByUserID: string;
  createdAt: Date;
  updatedAt: Date;
}

// An interface that describes the properties
// that a User Model has
interface PermissionModel extends mongoose.Model<PermissionDoc> {
  build(attrs: PermissionAttrs): PermissionDoc;
}

// An interface that describes the properties
// that a User Document has
interface PermissionDoc extends mongoose.Document {
  Code: string;
  Name: string;
  Description: string;
  ModuleID: string;
  Active: boolean;
  CreatedByUserID: string;
  UpdatedByUserID: string;
  createdAt: Date;
  updatedAt: Date;
}

const PermissionSchema = new mongoose.Schema(
  {
    Code: { type: String, required: true, unique: true },
    Name: { type: String, required: true },
    Description: { type: String },
    ModuleID: { type: mongoose.Schema.Types.ObjectId, ref: 'Module' },
    Active: { type: Boolean, default: true },
    CreatedByUserID: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    UpdatedByUserID: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    createdAt: { type: Date, default: Date.now() },
    updatedAt: { type: Date },
  },
  {
    timestamps: true,
    toJSON: {
      transform(doc, ret) {
        ret.id = ret._id;
        delete ret._id;
        delete ret.__v;
      },
    },
  }
);

PermissionSchema.statics.build = (attrs: PermissionAttrs) => {
  return new Permission(attrs);
};

const Permission = mongoose.model<PermissionDoc, PermissionModel>(
  'Permission',
  PermissionSchema
);

export { Permission };

Module.ts（這是模塊模型檔案）

import mongoose from 'mongoose';

// An interface that describes the properties
// that are requried to create a new User
interface ModuleAttrs {
  Name: string;
  Description: string;
  Active: boolean;
  CreatedByUserID: string;
  UpdatedByUserID: string;
  createdAt: Date;
  updatedAt: Date;
}

// An interface that describes the properties
// that a User Model has
interface ModuleModel extends mongoose.Model<ModuleDoc> {
  build(attrs: ModuleAttrs): ModuleDoc;
}

// An interface that describes the properties
// that a User Document has
interface ModuleDoc extends mongoose.Document {
  Name: string;
  Description: string;
  Active: boolean;
  CreatedByUserID: string;
  UpdatedByUserID: string;
  createdAt: Date;
  updatedAt: Date;
}

const ModuleSchema = new mongoose.Schema(
  {
    Name: { type: String, required: true },
    Description: { type: String },
    Active: { type: Boolean, default: false },
    CreatedByUserID: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    UpdatedByUserID: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    createdAt: { type: Date, default: Date.now() },
    updatedAt: { type: Date },
  },
  {
    timestamps: true,
    toJSON: {
      transform(doc, ret) {
        ret.id = ret._id;
        delete ret._id;
        delete ret.__v;
      },
    },
  }
);

ModuleSchema.statics.build = (attrs: ModuleAttrs) => {
  return new Module(attrs);
};

const Module = mongoose.model<ModuleDoc, ModuleModel>('Module', ModuleSchema);

export { Module };

我在路線中使用過：

import { Permission } from '../models/permission';
...
const Items = await Permission.find()
        .populate('ModuleID')
        .or(filter || {})
        .sort(sort || {})
        .skip(start || 0)
        .limit(length || 0);

      console.log(Items);

錯誤

“Mongoose 錯誤 MissingSchemaError：尚未為模型模塊注冊模式”

我今天的所有時間都用來找出問題，但不能。請幫幫我，我錯過了什么？

uj5u.com熱心網友回復：

解決方法是在路由開始時匯入模塊檔案。

import { Module } from '../models/Module';
import { Permission } from '../models/permission';
...
const Items = await Permission.find()
        .populate('ModuleID')
        .or(filter || {})
        .sort(sort || {})
        .skip(start || 0)
        .limit(length || 0);

      console.log(Items);

解釋是您需要執行以下行來注冊Module模型的架構：

const Module = mongoose.model<ModuleDoc, ModuleModel>('Module', ModuleSchema);
