型別缺少“Schema<any,Model<any,any,any,any>,{},{}>'型別的以下屬性：add、childSchemas、clearIndexes

我在 TypeScript 上有一個 Mongoose，它在沒有定義介面和型別的情況下作業，但是當我決定定義型別時，瘋狂開始了。我看過大量的手冊和主題，發現沒有人有類似的問題。我試圖嚴格按照手冊定義模型，但出現錯誤。這是我的模型檔案：

import mongoose from 'mongoose';
import { nanoid } from 'nanoid';

const GeoSchema = new mongoose.Schema({
    type: {
        type: String,
        default: 'Point',
        enum: ['Point'],
    },
    coordinates: {
        type: [Number, Number],
        index: '2dsphere',
    },
});

interface postInterface extends mongoose.Document {
    shortId: string;
    createdBy: string;
    title: string;
    description: string;
    tags: string[];
    location: {};
    images: string[];
    contacts: {
        email: Boolean;
        wa: Boolean;
        phone: Boolean;
    };
    type: 'available' | 'wanted';
    is_moderated: Boolean;
}

export const PostSchema = new mongoose.Schema(
    {
        shortId: {
            type: String,
            index: true,
            default: () => nanoid(),
        },
        createdBy: {
            type: String,
            index: true,
        },
        title: String,
        description: String,
        tags: [String],
        location: GeoSchema,
        images: [String],
        contacts: {
            email: Boolean,
            wa: Boolean,
            phone: Boolean,
        },
        type: { type: String, enum: ['available', 'wanted'] },
        is_moderated: Boolean,
    },
    { timestamps: true }
);

export const Post = mongoose.model<postInterface>('Post', PostSchema);

當我將它匯入另一個檔案時，就行了

return Post.create(post)

linter 給了我錯誤：

Type 'postInterface & { _id: any; }' is missing the following properties from type 'Schema<any, Model<any, any, any, any>, {}, {}>': add, childSchemas, clearIndexes, clone, and 37 more.ts(2740)

我用谷歌搜索了打字稿模型定義的例子，看起來對別人有用的東西對我不起作用。

我究竟做錯了什么？

更新

伙計，這太明顯了！我匯入模型的檔案如下所示：

import { Post, PostSchema } from '../models/post.model';
export class PostService {
    async createPost(post: any): Promise<typeof PostSchema | null> {
        return Post.create(post);
    }

    async getPostById(shortId: string): Promise<typeof PostSchema | null> {
        return Post.findOne({ shortId });
    }
}

所以事情在Promise<typeof PostSchema | null>. 當我將代碼更改為此時，錯誤消失了：

import { Post, postInterface } from '../models/post.model';
export class PostService {
    async createPost(post: any): Promise<postInterface | null> {
        return Post.create(post);
    }

    async getPostById(shortId: string): Promise<postInterface | null> {
        return Post.findOne({ shortId });
    }
}

感謝@lpizzinidev 將我推向正確的方向！
