I'm trying to create a prototype method for a "User" object. How is "create" undefined when I am literally declaring it to a function?
const mongoose = require("mongoose")
const userSchema = new mongoose.Schema({
username: {
type: String,
required: [true, "Field cannot be left blank"],
unique: [true, "That username is already taken"],
minlength: [3, "Username must be at least 3 characters"],
maxlength: [15, "Username cannot exceed 15 characters"],
},
})
const Doc = new mongoose.model("user", userSchema)
let User = (username) => {
this.username = username
}
User.prototype.create = function () {
return new Promise(async (resolve, reject) => {
try {
let doc = await new Doc({
username: this.username,
})
resolve(doc)
} catch (err) {
reject(err)
}
})
}
module.exports = User
I was able to solve it by changing the arrow function of my constructor to an anonymous function. I did some research and ES6 does not allow constructor functions to be arrow functions.
//previous code
let User = (username) => {
this.username = username
}
//correct code
let User = function(username) {
this.username = username
}
