Hi there, I'm currently exploring MongoDB and Mongoose. My goal is to prevent users of my API from storing duplicate contact names in the Mongo database, but unfortunately it's not working as expected.
This is how I have set up the validation: both name and phone number are required fields, with the added condition that the name must be unique; otherwise an error should be thrown.
const contactSchema = new mongoose.Schema({
name: {
type: String,
required: true,
unique: true
},
number: {
type: Number,
required: true
}
});
app.post('/api/persons', (request, response) => {
const body = request.body;
const person = new Contact({
name: body.name,
number: +body.number
});
person.save()
.then(saved => {
response.json(saved);
})
.catch(error => {
return response.status(400).json({
error: 'content missing'
});
});
})
While sending a post request with missing name or number does trigger an error, the unique value validation doesn't seem to be functioning properly.
