Problem with User.remove, it says that it is not a function

Question

I'm trying to post users on /user with express.Router() But it says that await User.remove is not a function. Maybe i need to import some more features? Here is code

import express from "express";
import User from "./Models/UserModel.js";
import users from "./data/users.js";
import Product from "./Models/ProductModel.js"


const ImportData = express.Router()

ImportData.post(
    "/user",
    async (req, res) => {
      await User.remove({});
      const importUser = await User.insertMany(users);
      res.send({ importUser });
    }
  );

ImportData.post("/products",async (req,res)=>{
    await Product.remove({});
    const importProducts = await Product.insertMany(products);
    res.send({ importProducts });
});

export default ImportData;

Here is error:

await User.remove({});
                 ^

TypeError: User.remove is not a function
    at file:///C:/react//frontend/Server/DataImport.js:12:18 

UserModel.js:

import mongoose from "mongoose";
import bcrypt from "bcryptjs";

const userSchema = mongoose.Schema(
  {
    name: {
      type: String,
      required: true,
    },
    email: {
      type: String,
      required: true,
      unique: true,
    },
    password: {
      type: String,
      required: true,
    },
    isAdmin: {
      type: Boolean,
      required: true,
      default: false,
    },
  },
  {
    timestamps: true,
  }
);

const User = mongoose.model("User", userSchema);

export default User;

I tried a lot, maybe here is another solving of this problem? Thank u in advance

Answer 1

In new mongoose versions, document.remove() is deprecated. Replace remove() with deleteOne() or deleteMany().

Check the mongoose documentation's deprecation warning here.

Answer 2

The object you are calling remove() on is a Model. Looking at its documentation, there indeed is no remove function; the only function whose name hints at similar behavior I can find is the deleteOne() and deleteMany() function found in the documentation.

The remove function is part of a Schema, as seen here in the documentation. In your code, a Schema is only used in the UserModel.js file, to create the Model.
