I'm practicing creating models and routes and am using postman to send a POST request to test it out. However, I keep getting the user is not a constructor error.
index.js (route)
const express = require('express')
require('./db/mongoose')
const User = ('./models/user')
const app = express()
const port = process.env.PORT || 3000
app.use(express.json())
app.post('/users', (req, res) => {
const user = new User(req.body)
user.save().then(() => {
res.send(user)
}).catch(() => {
})
})
app.listen(port, () => {
console.log(port + ' is aliiiiiiiive!')
})
User (schema)
const mongoose = require('mongoose')
const validator = require('validator')
const User = mongoose.model('User', {
name: {
type: String,
required: true,
trim: true
},
email: {
type: String,
require: true,
trim: true,
lowercase: true,
validate(value) {
if(!validator.isEmail(value)) {
throw new Error('Email is invalid')
}
}
},
age: {
type: Number,
default: 0,
validate(value) {
if(value < 0) {
throw new Error('Age must be a positive number.')
}
}
},
password: {
type: String,
trim: true,
lowercase: true,
required: true,
minlength: 7,
validate(value) {
if( value.toLowerCase().includes("password")) {
throw new Error("Password can't be 'password'.")
}
}
}
})
module.exports = User
mongoose.js
const mongoose = require('mongoose')
mongoose.connect('mongodb://127.0.0.1:27017/task-manager-api', {
useNewUrlParser: true,
useCreateIndex: true
})
I expect it to send back an object with the following information I'm sending on Postman:
{
"name": "Michael",
"email": "email@eail.com",
"password": "ThisIsAPassword"
}
You have to define a userSchema before compiling the model, like this:
const mongoose = require('mongoose')
const validator = require('validator')
const userSchema = new mongoose.Schema({
name: {
type: String,
required: true,
trim: true
},
email: {
type: String,
require: true,
trim: true,
lowercase: true,
validate(value) {
if(!validator.isEmail(value)) {
throw new Error('Email is invalid')
}
}
},
age: {
type: Number,
default: 0,
validate(value) {
if(value < 0) {
throw new Error('Age must be a positive number.')
}
}
},
password: {
type: String,
trim: true,
lowercase: true,
required: true,
minlength: 7,
validate(value) {
if( value.toLowerCase().includes("password")) {
throw new Error("Password can't be 'password'.")
}
}
}
})
const User = mongoose.model('User', userSchema);
exports.User = User
Now it is a constructor, because we are saying each instance of User
is a new
instance of userSchema
.
I figured it out. On the third in my index.js file, I left out require.
Instead of this:
const User = ('./models/user')
It should have been this:
const User = require('./models/user')
Thanks for all your help, everyone!
